Solar Power as a Work-From-Home Perks?

Solar Power as a Work-From-Home Perks?

Ever heard of Solar Power as a Working-From-Home Perk? Installing solar power systems is already a tedious process for homeowners, and with many of us working and learning remotely, we’re too distracted to get started. Those renting or living in states where policies have made solar power a no-go can forget about it — lower bills due to solar are a pipe dream. But as many companies scramble to keep their employees motivated and rethink perks while their employees work from home, a Washington, D.C.-based startup says it has a solution.

Arcadia describes itself as the first nationwide “digital utility” in the U.S. Since its founding in 2014, the company’s platform is now available in all 50 states and with more than 100 power utilities. Users can acquire a solar power subscription from Arcadia, buy as little as one solar panel or more, and see the results as a credit on their monthly utility bills.

Therein lies an opportunity for a company’s virtual human resources desk to offer a new benefit to employees.

It’s true that we’ve seen a decrease in emissions worldwide due to the novel corona virus pandemic; how much of a reduction varies by the sources consulted. But here’s the problem for companies: For those that are tabulating their emissions as part of their sustainability or environmental responsibility strategies, many of those emissions have simply shifted from the properties they own or lease to their employees’ individual homes. Solar power can help solve that problem.

After all, many individuals’ utility bills have bumped upward, as we’re leaving our devices charged and air conditioning units running with greater frequency — not to mention the fact we’re using our household appliances more (yes, opening that fridge door constantly as a procrastination tactic adds more to your utility bill in the long term). But with working from home becoming the reality for many through 2021, companies now have the chance to offer employees financial relief while swatting away some of their own emissions.

In a recent interview with Fast Company, Arcadia CEO Kiran Bhatraju said the company’s corporate clients so far include McDonald’s, SkySpecs and CustomerFirst Renewables. But with more companies saying that working from home for the most part ended up becoming a net positive after the initial shell shock, watch for Arcadia to win more clients as remote work is redefining the very notion of “perks.”

In Ghana, where the Corona virus has increased working  from home options for many employees especially in the banking sector. Nocheski has therefore developed  special packages solar packages at very competitive prices. Call 0244270092 for more information

Coronavirus (Covid-19) :China sneezes & solar catches a cold

coronavirus solar china

The coronavirus (Covid-19) outbreak has caused a slowdown of China economic growth. The International Monetary Fund (IMF) has cut China’s gross domestic product (GDP) growth outlook by 0.4% to 5.6% but also alerted of further alterations, taking into account the extent and magnitude of the impact of the coronavirus outbreak.

The current scenario in the country is going to have an effect on its power demand and generation. China is a world leader in renewable energy investment. The country has proved itself as a leader in wind power installation, wind turbine manufacturing and solar photovoltaic (PV) manufacturing.

The country’s renewable power sector is experiencing the impact of the Covid-19, specifically wind and solar PV, which could witness lower capacity additions in Q1 2020 due to suspended manufacturing and construction works.

China is a leader in terms of solar PV installations and the production of solar PV panels. The country has the largest installed solar power capacity of more than 205GW, contributing more than 35% of the global installations. China’s annual installation was expected to be approximately 30GW in 2020 and the outbreak is likely to impact solar installations at the end of the year in 2020.

Globally, China is the biggest manufacturing economy, including solar PV equipment manufacturing. The solar sector is expected to face the heat, given the tight capacity in solar equipment manufacturing. Of the top ten solar PV manufacturers in terms of module shipments, the majority of them are China-based. These include Jinko Solar, JA Solar, Trina Solar, LONGi Solar, Risen Energy, GCL System and Suntech. Coronavirus-hit province Zhejiang is home to a few of Jinko Solar’s manufacturing works, the largest Solar Module Super League (SMSL), while JA Solar is also involved in manufacturing operations in the province.

KEY FEATURES
Innovative solar cells
​Four bus-bar cell technology provides a more robust and powerful module ideal for utility scale applications
Low-light performance
Improved low light performance through advancements in glass technology and surface texturing
Weather resistance
Certified by TUV for high salt mist and ammonia resistance
Strong and durable
Tested and tried to endure up to 5400Pa positive and 2400Pa negative loads

Post Covid-19 outbreak, the Jiangsu province in China took the hardest hit in terms of solar PV production capacity as more than 60% of the country’s solar PV panels are made here as per the Gofa institute, a part of the Chinese government’s National Energy Administration (NEA).

The key manufacturing hubs in the Jiangsu province include Canadian Solar, LONGi Group, Trina Solar, Q-CELLS and JA Solar. Due to the outbreak, the solar power market has concerns with regards to material supply shortage and logistical restrictions due to closed borders, which could increase the price of solar modules that otherwise was rapidly plunging. The shortage will delay equipment deliveries and affect the solar sector’s global supply chain.

While the country is beginning to get back to work at a slow pace after the coronavirus outbreak, many factories have not yet started operating at a full capacity due to shortage of staff and raw materials. Solar PV manufacturers such as Trina Solar has alerted about production delays and LONGi Green has commented that there is no significant outcome on its solar PV panel sales and production and its shipment targets will also not experience any changes this year.

The NEA and the State Grid Corporation of China (SGCC) have notified about the threats coronavirus (Covid-19) outbreak poses to the power industry and the Chinese Photovoltaic Industry Association (CPIA) has recommended the Chinese government to delay connection deadlines of large-scale solar power projects on March 31 and June 30. In the current situation, late project completion will impact the amount of subsidies received.

The coronavirus (Covid-19) outbreak will affect the overall supply chain and solar installations not only in China but globally, mostly the in the US and other countries such as India and Australia, heavily dependent on Chinese raw materials and components. Many solar manufacturing plants located outside of China are dependent on Chinese imports for raw materials such as aluminium framing and solar PV glass.

With more than 75GW installed as of 2019, the US is majorly dependent on solar PV panel production from China. The country is already facing supply bottleneck since the extension in PTC and ITC granted in December 2019. The Q1 production delays due to extended Chinese New Year Holidays as a result of the coronavirus outbreak will worsen the situation for the US developers who will be forced to look out for alternative sourcing avenues.

In the short term, the shock-waves from the Covid-19-sparked collapse in the price of crude have the potential to cause serial disruptions to the energy sector supply chains and prompted oil companies to retrench spending to protect existing oil & gas investments rather than commit capital to renewables.

This has led industry analysts to forecast significant fall-out for the until-now swiftly expanding clean-energy sectors, with the debate now revolving round only how damaging it will be.

n Europe, renewable energy developers and their supply chains have a put a brave — but realistic — face on the immediate impact of Covid-19.

Danish utility Orsted’s chief executive, Samuel Poulsen, assessed the utility’s development plans to be “on track so far” and Germany’s EnBW announced surging profits from renewables had carried it to meet earnings targets early, making it “rock solid” to weather the coronavirus storm.

Both, in the same breath, recognised there were “clear risks” down the road as the pandemic sweeps the globe.

Wind turbine makers have been showing themselves to be resilient, temporarily shutting down nacelle and blade plants for safety reviews, but with the sector overall seeing manufacturing levels running at 96% , according to advocacy body WindEurope.

And, based on early soundings of its membership, SolarPower Europe is sticking to its expectation that the PV build-out in the EU will not be derailed from reaching 35GW by 2023.

The likelihood that this broad regional market stability would be maintained was given a shot in the arm following a statement by 27 EU heads of government in which they jointly argued that Europe’s Green Deal and longer-term energy transition strategy should be dovetailed via a “co-ordinated” approach to Covid-19 emergency measures built around the “green transition and digital transformation”.

US looks gloomier

Things look much less rosy in the US, where the pandemic has placed more than half of the wind power sector’s 44GW short-term project pipeline – and some 35,000 jobs – at risk, according to the American Wind Energy Association, while, by mid-March, the pandemic was already “taking a toll” on US solar, according to Abigail Ross Hopper, chief executive of the Solar Energy Industries Association

Bringing home the “solar power” of education

No comments yet

In the dark of night, students in a rural village in Ghana huddle around a kerosene lamp to complete their homework. Others shine flashlights to illuminate textbooks. The lack of electricity, nonetheless computers, dimmed the prospects of a bright future for students in the village of Kpantarigo. This was until Francis Abugbilla, a second-year doctoral student at the Henry M. Jackson School of International Studies at the University of Washington in Seattle, brought electricity to them in the form of solar power.

“The world is technologically-driven. I want to empower the children in my community by giving them a quality education,” he said. “I don’t want the children in my village [of Kpantarigo] to lag behind the world.”

Even though his village of over 1,500 had no electricity, computers, schools or clinics, he knew from his own experience that education is the impetus for change.

Making education matter
Born and raised in a small farming community, Abugbilla worked as a shepherd and began his formal education at 12. He was determined to excel. He walked nearly two hours a day to and from the elementary school in another village. The money his family scraped together paid for the kerosene to light the lamp for his studies.

“I was economically disadvantaged,” Abugbilla said. “Education was the key to change my family’s situation and my community.”

At 17, he participated in a French quiz competition in the regional capital of Bolgatanga. This day changed his life: It was the first time he saw a computer.

“At first, I thought it was a TV because of the desktop monitor,” Abugbilla laughed. “I needed to know how it worked and how I could use it.”

Later in high school, he looked over the shoulders of his classmates. He was mesmerized as they pounded keys and information magically appeared on the screen. He wasn’t confident enough to try. Until his instructor publicly shamed him.

“He said why can’t you do the basic things on a computer,” Abugbilla recalled. “My self-esteem was quite low.”

Determined to prove his instructor wrong, Abugbilla practiced typing with the help of a friend. Not long after, he bought his own Hewlett-Packard laptop as part of a scholarship he earned for his studies.

Becoming a global steward
Abugbilla excelled in his undergraduate studies at the University of Cape Coast, Ghana, where he earned a bachelor’s of education in French honors degree with a minor in English. But he had his sights on coming to America. He applied to the University of Arizona, Tucson and received a full-ride scholarship.

Francis Abugbilla

Francis Abugbilla, a Jackson School doctoral candidate, shares solar power with students in Ghana. Pictured is Francis giving a solar lamp to one of three winners of a global affairs competition that he initiated, September 2018.

As one of five to graduate from college in his village and the only one to obtain a master’s degree, Abugbilla was determined to climb the highest rung of education.

After completing his master’s degree in French, he applied for doctoral programs at 10 universities including the University of Washington’s Henry M. Jackson School of International Studies.

He received six acceptances with four full-ride scholarships. But the UW’s Jackson School stood amongst the crowd.

“I chose the Jackson School because of the accelerated nature of the program. It is not like the traditional doctoral program. I wanted to experience academia and the practical side of the policy world,” he said.

Abugbilla also received the Henry M. Jackson Doctoral Fellowship, funded by the Henry M. Jackson Foundation, that annually supports a deserving doctoral student with promising potential.

Finding a meaningful solution
Despite all his accomplishments, Abugbilla didn’t forget about the young people in his village.

“I had this idea of bringing electricity to my village through solar panels,” he said. “It was this daunting task. I didn’t know who to reach out to, where to turn, how would I fund this?”

Abugbilla shares a Ghanaian proverb: “The gods that look for yams for a child in the forest, will look for a hoe for digging the yams.” Where there is a vision, there is a provision, he explained.

In 2018, he found that chance thanks to the UW Marcy Migdal Fund for Educational Equality, a $1,000 fund supporting exceptional students engaged in finding meaningful solutions to global problems. With the support, Abugbilla installed a solar panel in the village school, allowing teachers to prepare lessons and students to have computer lessons and return to the school in the evening to do their homework. He also initiated an annual global studies competition in the school.The equipment installed include the Victron Energy Phoenix Inverter VE.Direct 500VA and  Victron Energy BlueSolar MPPT 75/15 

The Marcy Migdal fund is administered by the Center for Global Studies, which is housed at the Jackson School and is also a U.S. Department of Education National Resource Center. Students from all three campuses are encouraged to apply for the fellowship in February, with awardees announced in June.

Joel Migdal, professor of international studies who set up the Migdal fund in his late wife’s name said: “I couldn’t think of a project that my late wife, Marcy, who was an educator and social justice activist, would have found more meaningful than that of Francis’s. It brought tears to my eyes.”

Abugbilla continues to fundraise on GoFundMe to expand the solar panel project. He said he has been overwhelmed by the support he received from UW students, professors and others in the community.

“The Marcy Migdal fund was the tool to get me to dig the yam,” Abugbilla beamed. “It was the opportunity that opened more opportunities for me.” Tamara Leonard, Managing Director of the Center for Global Studies, added that the project exemplifies the kind of work that the Fund is intended to support.

Teaching others at UW and beyond
Shortly after initiating his solar power project, Abugbilla was invited to and participated in the Clinton Global Initiative University Annual Conference at the University of Chicago, an event honoring student leaders dedicated to addressing pressing challenges in the world. He also recently served as the keynote speaker for the 2019 Africa Now Youth Leadership Conference, an organization based in Seattle dedicated to inspiring African youth. In June 2019, he will attend the Global Youth Advancement Summit at the Michigan State University to talk about his solar power project.

Thanks in part to support from Carnegie Corporation of New York, in winter 2020 Abugbilla will help teach a course in the Donald C. Hellmann Task Force Program, an experiential learning capstone for undergraduate international studies majors. The Task Force, on energy interventions in Sub-Saharan Africa, will be led by Danny Hoffman, a professor in anthropology at the UW.

While Abugbilla plans on continuing his research at the Jackson School with a focus on peace, violence and security, his heart is still in Ghana.

“The goal is to electrify the schools  with solar power and then scale it up to the entire community,” he said. “It is important that people take their destiny into their own hands and effect the needed change in their lives. I want to spur them into thinking innovatively and outside the box.”

As just one of five in his village and in his family to graduate from college, and the only one to earn a master’s degree, Abugbilla is well on his way to propelling his community with solar power and the world forward.

Lithium SuperPack batteries – an all in one solution

No comments yet

Lithium SuperPack batteries – an all in one solution .These new Lithium-Ion, LiFePO4 chemistry batteries are often an ideal replacement for many 12V and 24V marine, automotive, caravan, motorhome, work vans and similar battery applications. It might even be for an overland motorcycle if using the smallest 20Ah version; to recharge a camera, phone or laptop for instance.

Other examples – take a typical small boat or van which may have a 110Ah to 220Ah lead-acid leisure battery for light continuous loads such as lighting, laptops, phones, instruments, powering a diesel heater, a fridge etc. And for shorter term loads maybe add a small inverter to charge power tools, run a small microwave or travel kettle for example. Using one SuperPack battery it matches well with the Phoenix Inverter VE.Direct 250VA – 1200VA range. Maybe you’ll add in around 100 to 200Wp of solar panels too using a small MPPT.

Regardless of the use, whichever SuperPack you choose it’ll be lighter than lead, can be smaller if you wish or give you more Wh in the same space – plus give you around 5 times the cycle life.

The main difference to Victron’s other lithium (often more kWh) offerings are the SuperPacks keep everything in one package, by having an integrated BMS and safety switch built-in. No additional components are needed as the internal switch will disconnect the battery in case of over discharge, over charge or high temperature. Simple, compact and safe.

If you are considering a new battery don’t immediately discount Lithium as being too costly. Whilst it is true that the capital cost of Li-ion is greater than that of quality AGM or Gel batteries – it is also true that the cost of ownership can be less than lead acid types. Much depends on your application, but rest assured – life with Li-ion is far less hassle than lead.

Over the last 8 years on my sailing yacht I’ve run AGM lead leisure batteries and Lithium-Ion propulsion batteries. Initially it was AGM for propulsion before discovering the effectiveness of Lithium. That journey taught me a lot about loads, capacity, cost and battery life – it’s one of the reasons why I think we’ve reached a tipping point and why these new SuperPack batteries may just be the ticket for your next project or battery replacement.

If in the first instance you are unfamiliar with AGM vs Lithium, then here’s a blog that explains that.

When to use a SuperPack?

Every battery size and type has it’s own particular use. For instance you may use the Lithium battery 12,8V & 25,6V Smart and the Lithium battery 24V (LiFePO4 & NMC chemistries) ranges (all of which have an external BMS) in quite different applications to the new SuperPack range. So, where to use the SuperPacks?

When it comes to replacing lead acid type batteries such as AGM and Gel in many applications, the SuperPack range can be considered the next generation after lead – making it far easier to replace lead with lithium. The only caveats being replacement is down to certain parameters being met, namely – Capacity (Ah), Voltages (12.8V & 25.6V), Discharge and Charge currents (C rates). Do in that case be sure that your chosen replacement fits your criteria by checking the datasheet and be aware the SuperPacks can be connected in parallel, but not in series. Hence in that case you would consider the other Victron lithium products named above.

The Lithium SuperPack

Victron Energy’s recently introduced Lithium SuperPack range comes in the following capacities and voltages:

12.8V & 25.6V Lithium SuperPack batteries:

  • 12.8V – 20Ah
  • 12.8V – 60Ah
  • 12.8V – 100Ah
  • 12.8V – 200Ah
  • 25.6V – 50Ah

These SuperPacks will give you 2,500 cycles to 80% depth of discharge at 25°C, much more than lead.

Comparison: SuperPack 60Ah LiFePO4 vs 90Ah AGM

Let’s compare the 60Ah Li-ion to say a typical 90Ah AGM battery discharged to the commonly accepted economic cycle life of 50% discharge for lead. That would give us 600 cycles at that DOD for the AGM compared to 2,500 at the even deeper discharge of 80% for the LiFePO4. Already you can see you may need to replace your lead-acid type battery 2 to 4 times as often as the Lithium. Of course loads, operating conditions and calendar life have to be factored in too. Regardless you get the idea – Lithium does more and lasts longer.

The benefits of Lithium don’t stop there though. Whilst LiFePO4 chemistry is considered the safest of them all, it’s worth considering other factors too to decide whether the reduced weight and volume of say NMC is of more importance for your application than LiFePO4 for example. Victron Energy do both types. These star graphs do a good job of explaining the differences: https://batteryuniversity.com/learn/article/types_of_lithium_ion

Notes for the table above:

  • Useable energy and cycle life are based on 80% depth of discharge for Li-ion and 50% for AGM, these being considered the most economic use of those battery types.
  • Higher loads with lead will further reduce available Wh (Peukert’s Law) when compared to Li-ion.
  • Capacity is also reduced for both types by temperatures below their 25°C temperature rating (see their respective datasheets)

Make what you will of the above and whilst you are pondering the pros and cons don’t forget to take these additional factors into account for the comparison above.

  • Shipping: If you are replacing your lead from 2 to 4 times as often as Li-on and the fact that the lead weighs around 3 to 4 times as much (depends on Li-ion chemistry used) – then do consider the extra shipping costs.
  • Voltage stability: The voltage profile is far flatter for Li-ion compared to lead.
  • Voltage sag: Subject to the load, voltage sag with lead is significant compared to Li-ion.
  • Li-ion has much faster charge times and if charging from a generator it saves on generator runtime.

Other factors to consider

Is the above enough to convince you of why Lithium might be a better alternative than AGM or indeed Gel? Personally I’m sold on Lithium, but if you are not here’s a few things further to consider:

  1. A lead-acid battery will fail prematurely due to sulfation if it operates in deficit mode for long periods of time (i.e. if the battery is rarely, or never at all, fully charged). It will also fail early if left partially charged or worse, fully discharged.
  2. By comparison a Lithium-Ion battery does not need to be fully charged. This is a major advantage of Li-ion compared to lead-acid which needs to be fully charged often to prevent sulfation.
  1. Efficiency. In several applications (especially off-grid solar), energy efficiency can be of crucial importance. The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80%.
  2. The round-trip energy efficiency of a Li-ion battery is 92%.
  1. The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy are required (battery operating in 70% to 100% charged state).
  2. In contrast, a Li-ion battery will still achieve 90% efficiency even under shallow discharge conditions.

Make the switch?

Are you ready to make the switch from Lead to LiFe? If you’ve considered all the above I suspect you might be. And if you need more useable Ah why not run the sums on say a 100Ah Lithium SuperPack vs 220Ah AGM using the process I have above. Or indeed a 200Ah Li-ion SuperPack vs your choice of lead.Lithium SuperPack batteries – an all in one solution

Don’t forget too that Lithium has little or no Peukert effect when compared to Lead types. This is especially important when considering loads with lead-acid higher than 0.05C (Battery Ah divided by 20 or Ah multiplied by 0.05). In other words for a 100Ah AGM with a Peukert of say 1.15 or more and discharging at 0.25C (25 Amps in this case – which is 5 times the 20 hour rate) there will be significant reduction in capacity – as there will be at colder temperatures too. Li-ion has a Peukert of around 1.05 when compared to lead of around 1.15 to 1.25.

So – if you were discharging that 100Ah lead at 5 Amps (the 20 hour discharge rate at a temperature of 25 degrees centigrade) then the full capacity of 100Ah is still availaable and it’s not shrunk due to Peukert. But now if it were 0.25C, it’ll be around 80% of that original 100Ah capacity – or less, subject to load type and duration.Lithium SuperPack batteries – an all in one solution

The bottom line is you no longer have the Ah you purchased, whereas with Lithium there is little to no effect, helped by a lower Peukert and good voltage stability. That is especially important with constant inverter loads – a place where lithium shines. If you want to learn more about Peukert and run a spreadsheet to see such effects, then I have found this link most helpful.

Finally and one I’m always grateful of is vastly reduced charge times, no more waiting for hours of lead absorption charging to get from 80% to 100% SOC. Conversely Li-ion flies up to around 98% SOC in bulk with those last few percent in absorption to fully balance the cells – and unlike lead you don’t always have to fully charge to 100% as often. Note that your 12V charging system needs to accommodate 14.2V – 14.4V ‘absorption’ and ‘13.5V’ float. If charging from an alternator also note the maximum continuous charge currents for the 12.8V range, by checking the datasheet.

Downsides

Not wanting to sound too evangelical, we also need to consider the few downsides of Li-ion.

  • Higher upfront cost and to some extent higher capital risk.
  • Charging is restricted to the +5°C to +45° range, subject to an internal means of blocking the charge source when the temperature is below +5°C. Note this is currently automatically possible with Victron MPPTs when used in conjunction with the Smart Battery Sense for instance. Other products are being worked on to achieve this too and documentation to that effect will be updated in due course.
  • The SuperPack (unlike other Victron Lithiums) is not designed for series connections.
  • The peak and maximum continuous discharge current of the SuperPack range is not as much as some of our Lithium batteries as its related to the BMS and the disconnect being internal to the battery – so do check the datasheet to make sure the current peak and discharge ratings suit your needs – or choose from the Lithium battery 12.8V & 25.6V Smart or the Lithium battery 24V range or build a parallel SuperPack bank.Lithium SuperPack batteries – an all in one solution

Conclusion

Whatever your decision when purchasing new batteries, maybe it is time to give the Lithium SuperPack batteries a chance. There’s LiFe after Lead you know – but as I’ve shown that all depends on what you want to achieve. Is it less weight, less volume, maybe it’s capacity or voltage or any of the multitude of factors that go into choosing a battery system.Lithium SuperPack batteries – an all in one solution

Siemens partners WestPark for industrial park in Takoradi

Siemens has announced it has signed a Memorandum of Understanding (MOU) with WestPark Enterprises to develop an expandable microgrid solution for the fast-growing industrial and business park based in Takoradi, Western Ghana.

The Westpark aims to eliminate many of the challenges faced by companies doing business in Sub-Sahara Africa, such as access to reliable power, water, broadband internet and transport.

 The new industrial park is poised to accelerate the transformation of Takoradi – Ghana’s third-largest city.To lay the foundations for reliable, competitive and efficient energy, WestPark has entered into a partnership with Siemens.

As part of the agreement, Siemens will develop a 250kW microgrid that controls the energy generation for the initial phase of buildings to be constructed at WestPark.

Siemens will design the microgrid so that the first phase of WestPark can be powered entirely by renewable energy and therefore provide a sustainable and cost-effective solution for tenants.

On-site photovoltaic panels will power the microgrid and a back-up battery storage solution will be sourced as well.

The grid can be expanded as more buildings are added with the aim of ensuring that the park remains powered by renewable energy.

According to Sabine Dall’Omo, CEO of Siemens Southern and Eastern Africa, “This project is perfectly in line with Siemens’ vision for future business in Ghana and other African countries. As a company, we are continuously looking for new responsible and efficient energy and infrastructure solutions, and our collaboration with WestPark is a good example of how we can support partners with similar goals.”

Siemens is specifically committed to economic growth across Africa, and in doing so in a forward-thinking manner by implementing environmentally sustainable solutions that will help its partners and customers succeed in today’s environmentally-conscious global market.

Siemens AG is a German conglomerate company headquartered in Berlin and Munich and the largest industrial manufacturing company in Europe with branch offices abroad. The principal divisions of the company are Industry, Energy, Healthcare, and Infrastructure & Cities, which represent the main activities of the company.

Ghana:Organizations to shift to solar net metering system

Mr Kwabena Otu Danquah, the Head of Renewable Energy Promotion of the Energy Commission, has advised organisations to shift to the solar net metering system to save them from getting into the higher consumption rate bracket.

 

He said net metering was a mechanism that fed the national grid with surplus solar energy from households while assisting them to save cost and urged consumers to take advantage of it.

Mr Danquah was speaking at a two-day solar industry workshop in Accra organised by the Netherlands Development Organisation (SNV) and the Association of Ghana Solar Industries (AGSI) on current initiatives and opportunities in Ghana’s energy sector.

He said the Energy Commission, in collaboration with the Electricity Company of Ghana, had installed 35 net metering systems in various homes in Accra on a pilot basis.

“We are waiting for the Public Utilities Regulatory Commission (PURC) for the gazette to ensure that the new solar metering system fully takes off in Ghana,” he said.

Mr Danquah said the Energy Commission had created the enabling environment to ensure the attainment of enough renewable energy targets by 2020.

He said by the provision of the Renewable Energy Act 2011, 832, the Energy Commission, in collaboration with the Ghana Standards Authority, would enforce the law on the importation of renewable energy products that would meet good standards and certification.

He said: “The solar technology we know are perfect but the installation is the problem, hence the need for the Energy Commission to license all electricians and develop a training curriculum to train technicians to ensure good certification of solar.”

Mr Emmanuel Aziebor from the Netherland Development Organisation, a resource person, urged stakeholders in the solar industry to come out with substantive business models to convince the microfinance companies to invest in solar energy.

He advised the technical experts to support and sustain the technology whilst training more technicians on it.

Mr Aziebor said: “We need to have people prepared, trained and exposed to solar energy while looking at the local production of the products in future.”

Mr Eric Omane Acheampong, the President of AGSI, advised the members to develop activities on networking to enable them to assess their progress while sharing knowledge.

Mr James Robinson, the SNV Leader for Energy Sector, Ghana, gave the assurance that the SNV would continue to facilitate the activities of AGSI to sustain and promote solar energy in the country.

Solar PV Power Paradigm Shift- The Ghana case

Solar PV Power Paradigm Shift- The Ghana Energy

Solar PV Power Paradigm Shift- The Ghana case.I am not that kind of a man, but I have been in the company of other men who in the midst of challenges rather saw them as opportunities to change the paradigm.

I strongly believe that very few energy planners and experts would disagree that Energy Independence for Ghana is an important, even urgent, goal.

But the question remains, is shifting the energy paradigm realistic; and if so, how?

And do our politicians and related institutions have the needed passion and spirit to embrace the new paradigm in our energy sector?

In recent years it has become so glaring that the conventional energy paradigm (fossil fuel tradition) has rapidly lost ground in comparison to the concept of Sustainable Development, as it is based on the intensive use of non-renewable fossil fuels — causing environmental degradation and posing Global Energy Security Risks.

Thus, a modification in our energy paradigm is necessary for our energy independence. A paradigm shift in the goals of energy policy should take place: toward independence, security of supply and climate change. Transition to a sustainable energy system is one of the critical challenges humankind faces in achieving energy independence in the new millennium.

Ghana is a country that has unbelievable solar energy potential; but, sadly, solar energy sources contribute only 0.1% (on-grid+ off-grid) of the total installed capacity for the total installed power capacity of 2104.5 MW in Ghana. (VRA: Facts & Figures).

Some people may say I am overly obsessed with the idea of solar energy for our small but incredibly energy-resource-rich nation.

It’s true – I am! But is it practical for Ghana to actually pursue this objective?

Talking of our potential, Wa — capital of the Upper West Region — has the highest level of solar irradiation (5.524 KWh/m2-day) across the country.

May is the month with the highest solar irradiation (5.897 KWh/m2-day), with August recording the lowest measurement (4.937kWh/m2-day) in Wa.

Akim Oda, conversely, is the location that records the lowest radiation (4.567kWh/m2-day) measurements across the country.

The highest measurement in Akim Oda was recorded in the month of April (5.176kWh/m2-day) and the lowest in August (3.802kWh/m2-day). See Table 1. 

As a nation we are blessed with daily sunshine that averages 5 hours, which ranges between about 7 hours and 4 hours for the northern and southern regions of the nation respectively. Ghana also has annual average daily solar radiation of about 4.5 to 5 KWm2/day.

Assuming we are to use only 23,854km² which is 10% of the total land area (238,585 km²) of Ghana to harness the sun’s energy with PV panels of 15% conversion efficiency, then Ghana would harvest 4,114 TerraWattHours of energy per year. 

This amount is equal to 2.42billion barrels of oil.

Consequently, if we juxtapose this amount with our current oil production in the Jubilee Field, then it is about 27 times the current crude oil production of Ghana per year.” See Chart A on Ghana PV Output.

In Ghana, Solar PV applications are gradually receiving acceptance in most places. However, despite improvements in local Research and Development (R&D) efforts, the body of knowledge on these technologies and their market potentials is considerably inadequate.

Launching major national initiatives on these technologies — such as the President’s 200,000 solar rooftops for households — requires a robust knowledge base and capacity.

In all, PV technologies are showing increasing promise in terms of efficiency improvements and cost. The estimated lifetime of PV modules are 25 years, and this makes them exceptionally attractive for investors.

Today, except for the Solar PV Panels produced in Kpone-Tema by Strategic Power Solutions (SPS) — a subsidiary of Strategic Security Systems International Limited, almost 80% the PV modules on the Ghanaian market are imported.

Solar PV systems can be extensively used for a wide range of electrical energy requirements: including solar home systems, water pumping, refrigeration and telecommunications that will reduce the load curve of electricity demand.

It has been estimated that solar rural electrification is about 30% cheaper than the cost of grid extension to rural communities that are about 18 to 20km from the nearest grid station.

However, there are still economic and institutional obstacles that limit this ability to self-generate power. For instance, while it is practical to install solar panels on a home, it is more difficult to scale-up these systems for commercial and industrial-sized projects. Scale is a critical issue in energy generation, as with scale comes lower project costs and greater efficiency.

For privately distributed generation projects, both small and large, to make greater contributions toward our national energy independence, there needs to be continued evolution of the bold policies that first introduced grid-connection rights and net metering in our renewable energy act.

The government must as a matter of urgency assist all consumers anywhere in the country to benefit from the net-metering incentive for solar power consumers. Again, due to the high upfront cost, government must establish a renewable energy revolving credit fund whereby solar consumers can borrow money to finance solar systems without making large up-front payments and without paying high interest rates to banks or private financiers.

Also, the PURC must establish a coherent pricing tariff for distributors to buy power from private solar-farm developers. This could unlock an untapped source of clean, reliable, economical power for Ghana.

While not easy to accomplish, these advances are achievable – and, importantly, they don’t need to cost the tax payers any money. However, they depend on the political will and leadership of our energy-sector authorities.

Why Bill Gates thinks Solar is not the energy solution Africa needs

No comments yet

 

Bill Gates once again shunned solar power from his vision for energy access in Africa in his talk at the University of Pretoria in South Africa on Sunday, where he argued that whilst “cheap, clean energy” is what Africa needs, solar does not fit the bill.

During the delivery of his Nelson Mandela Annual Lecture, the Microsoft founder and philanthropist identified that Africa, like the rest of the world, is in need of a “breakthrough energy miracle that provides cheap, clean energy for everyone.”

Africa is more dependent on such a phenomenon than other continents, because seven in ten Africans still lack power at present, while more than 500 million Africans still will not have electricity by 2040.

This is not the first time Gates has taken a less than welcoming stance to solar power. In February, during an interview with a news outlet, he echoed a similar thought. “When I say ‘an energy miracle’,” he said, “I mean that there will be some form of energy whose 24-hour cost really is competitive with hydrocarbons given, say, 20 years of learning curve.

“You invent it, then you look at how much its costs go down over the next 20 years, that it really beats hydrocarbons.

“You might say, well, aren’t people saying that about wind and solar today? Not really. Only in the super-narrow sense that the capital costs per output, when the wind is blowing, is slightly lower.”

In fact, Gates has been advocating anti-solar sentiment for a while. In 2014, he blogged about energy poverty, arguing for outdated fossil fuel solutions to tackle the electricity deficit in underdeveloped economies, characterising energy poverty as a climate issue.

Solar is ‘not enough’

In the speech on Sunday, the software entrepreneur recommended increased investment in renewables, namely hydropower and geothermal. He went on to argue that recently launched solar power initiatives have not been enough:

“There has been a lot of experimentation with small-scale renewable energy, including micro solar,” he said. “This approach can provide individuals with some electricity for basic purposes, but it’s not going to be the solution for the continent as a whole.”

PV Tech contacted the South African Photovoltaic Industry Association (SAPVIA), who vehemently disagreed with Gates’ sentiments.

“To downplay the role that solar photovoltaics (PV) can play as part of a unique African energy mix in the strive to alleviate Africa’s energy constraints would be irresponsible,” a spokesperson said, whilst citing data that should deem solar a ‘no brainer’ solution for Africa: “Africa has 7 of the 10 sunniest countries on earth and, according to IHS Technology, a US-based economic and energy market research company, Africa’s total solar power–generating capacity is projected to reach 3,380MW by 2017.”

Solar deployment in Africa

In fact, solar power is undergoing rapid deployment and implementation as many countries across the continent are battling energy crises and look to alternatives to expensive fossil fuels such as diesel and coal. A series of feed-in tariffs and solar tenders have offered a foray into a solution that not only is clean and inexpensive, but is easily accessible.

In South Africa in particular, the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) has successfully awarded 965MW of new solar capacity, which SAPVIA points out “is being delivered on time and on budget”.

“The rapidly escalating uptake of the technology in the rest of Africa can be clearly seen,” argued SAPVIA. “Expedited solar PV roll-out is being seen as supportive policies and regulations, such as the Get FIT Programme are developed and implemented. These policies and programmes, combined with the drop in the cost of PV technology (currently fully off-grid solar-PV technologiesdeployed at site can be deployed for as little as US$ 0.15/kWh and they do not require additional expensive transmission networks to move the electricity around), [we] see solar PV will make a significant impact on Africa and its energy challenges.

“One can expect – as has happened in South Africa – as the necessary supportive policies and regulations are scaled up, the rest of Africa will experience an increased uptake of solar PVtechnology. New renewable energy markets in Africa are already showing greater appeal to international and local investors – further spurring the uptake of solar PV in African markets.”
