Solar trees as you can see above and below, are decorative ways of producing solar energy. The idea was first put into practice in Austria, a few years ago. In Europe, they are usually used for street light. They are able to provide enough light during the night-time even when the sun did not show for as much as four days in a row.
In San Diego, California, Envision Solar, a developer of solar integrated building systems, is planting Solar Trees in parking lots.
The project incorporates complete sustainable design elements and integrates architectural form with renewable energy’s functionality to increase property value, produce electricity and offset carbon emissions.
Not only that they use the sun to produce energy, but they also shade cars, displace unwanted rain run-off, and even have a place to plug in electric vehicles. A solar parking lot is also being tested as a prototype at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. The facility uses its solar for plug-in hybrid electric vehicles.
The company presented its innovative projects at the 1st Sustainable Infrastructure Financing Summit, Global Energy Basel (11-12 January, 2011), where representatives of 40 of the world’s cities have met to help their municipalities find investors – also attending – for sustainable infrastructure projects such as energy efficient buildings and transport and provision of renewable energy supplies.

764 days agoTrees are natural photovoltaic panels. Why not imitate them? Average leaf captures only 0.1 % of direct and dissipated light. But we have in our disposal PV panels that are capturing from 10 % up to 40.5 % of visible light to electricity. Besides, the underlying area can also be used for some purposes (like parking).

474 days agoSolar panels are becoming so cheap and each year have a higher efficiency. A new discovery will push effficiency from 20 to 70 %. That’s much higher than the efficiency from power plants, which have an average efficiency of 40%. They are the future and coming sooner than most people think. Forget new coal or nuclear power plants, buy solar panels yourself, they produce cheaper power than you pay now. Especially in poor countries without a power grid people are now able to produce their own power, at much lower prices than with a diesel generator. Solar power will be with us for the next 5 billion years, without pollution or dwindling resources, available for everybody.

350 days agoHow and where we can improve skill training aspects in renewable energy like solar panel production, maintenance or marketing?
Is there curriculum available on modular form in the field of renewable energy? Where can I get such sources?
