BMW goes green with Bamboo & Solar

German automaker BMW has unveiled its new solar carports in South Africa, which it will begin rolling out in July.

The BMW i solar carport supplies an average of 3.6 kW of solar power straight to the BMW i Wallbox, which is used to charge electric and plug-in hybrid BMW models and which is equipped with a live readout of how much power is being generated by the sun.

Tim Abbott, CEO of BMW Group South Africa and Sub-Sahara, said the company was the first automaker to offer such a broad-based EV smart charging product to reduce costs for customers. The rollout is part of the company’s global efforts to expand home and publicly accessible charging infrastructure for electric vehicles, Abbott added.

In the coming months, BMW Group South Africa will expand the installation of the solar carport in major cities, including Johannesburg, Cape Town and Durban, for public charging.

Customers and fleet companies will also be able to order the solar carport for home and office charging.

“We have always emphasized that in order for electric vehicles and plug-in hybrid electric vehicles to be successful, we need to firstly increase consumer confidence in the viability of electric vehicles and secondly make public charging easily accessible for customers who purchase these cars,” Abbott said. “The roll-out of the solar carport is also an emphasis on this philosophy.”

The solar carport is produced by PV solar system designer and installer Sunworks. It is made of high-end bamboo and stainless steel housing for the glass solar modules.

Bamboo is considered a particularly sustainable and high strength-to-weight ratio natural composite material useful for structures, BMW said.

The problem with Apple:too much money ,too much power

No comments yet

Apple has a solar power problem. It has too much of it. Worldwide, Apple gets 93% of the electrical energy it needs from solar and other renewable sources. That electricity runs its stores, offices, and datacenters worldwide. But in California and Nevada, it gets more electricity than it can use from the solar power installations it has constructed.

Apple Inc. plans to sell excess electricity generated by solar panels on the roof of its new headquarters in Cupertino, California, joining Google parent Alphabet Inc. in efforts to trade on the energy market.

A subsidiary named Apple Energy LLC has applied to the U.S. Federal Energy Regulatory Commission to sell power from the site’s solar panels and hydrogen fuel cells, as well as from solar farms, hydroelectric plants and biogas facilities in Oregon, North Carolina, California, Nevada and Arizona, according to a June 6 application submitted by Apple to the agency. The filing was reported earlier by 9to5Mac.com.

Apple, which plans to move into Apple Campus 2 next year, and Google are among the biggest investors in energy projects outside the utility industry.

The iPhone maker spent $850 million last year on a 130-MW solar farm south of San Francisco. If Apple’s application is approved, it will be able to sell energy directly to customers, rather than through an energy utility, beginning Aug. 5. It says in its application it should be able to sell energy at market rates since it’s not a big energy company and can’t influence the price of electricity.

Even with the excess capacity it has at the moment, Apple plans to add another 521 megawatts of solar power capacity worldwide, according to its 2016 Environmental Responsibility Report. Is there a connection between the desire to add renewable energy capacity and Apple’s not-so-secret plan to build an electric car? Apple is known to have an interest in electric car charging technology. Perhaps it plans to create a network of electric car recharging stations to compete with the Tesla Supercharger network?

It would be an excellent marketing strategy if it could claim all the electricity needed to recharge electric cars comes from renewable sources. Tesla already gets the power for its Supercharger stations from some renewable energy sources, but it cannot say all the electricity it needs for the network comes from solar power. At least not yet. Google secured similar rights back in December 2010 under the trade name Google Energy.

Victron Energy Multiplus inverter -improved faster switching

Victron Energy Multiplus inverter -Now improved with faster switching to grid

Victron Energy Multiplus inverter -Now improved with faster switching to grid.It can now switch much faster from inverter mode to mains mode. Combined with our high peak power ratings, this makes it possible to switch to mains mode before shutting down in an inverter overload alarm. This is especially useful in Self-consumption Hub-1 and 2 installations: it allows using an inverter/charger with a nameplate power below the system power. Victron Energy Multiplus  inverter improved: faster switching to grid

The old hardware will take approximately 8.5 seconds to switch from inverter- to charger-mode, the new hardware can do it within half a second. Some notes:

  • single phase installations will be even faster than the half a second mentioned;
  • fast switching is only possible in the 3xx firmware versions. The difference between 3xx on one hand, and 1xx and 2xx on the other hand is approximately another 0.5 second in the worst case scenario: slightly differing frequency, and inverter being 180 degrees out of sync with the grid;
  • all larger models, 3kVA and upwards, already have fast-switching since a long time;
  • do not forget the other limit to using an ‘undersized’ Victron Energy  multiplus Compact in an installation: the AC transfer capacity. Max system load may never exceed the transfer switch capacity;
  • the load-shedding functions in the self-consumption hub-1 and 2 Assistants give options to further undersize a Victron Energy  Multiplus Compact: use an external relay which is controlled via the Auxiliary output;
  • mentioned switching delays have not been measured exactly;
  • for parallel and three-phase operation, please check the Disqus comments below.

Lots of little details, but all together the conclusion is that this significantly reduces the chance of a Victron switching off in overload condition. Victron Energy  inverter improved: faster switching to grid

Availability

Despite stock and production logistics, all different models are shipping with the new hardware. Below table gives an overview of the current situation, from our main warehouse DSV in the Netherlands.
