– Solar Innovations 2020
Solar Innovations 2020 New solar energy innovations are being unveiled at Intersolar 2020 in San Diego this week, including the California launch of a concrete solar shingle, a unique under-the-panel battery storage configuration, and a single-axis tracker that can accommodate a 10% grade on undulating sites. And one forward-looking company is now buying up broken […]
– Correcting Anti-Renewable Energy Propaganda
In 1989, pro-nuclear lobbyists claimed that wind power couldn’t even provide 1% of Germany’s electricity. A few years later, pro-nuclear lobbyists ran ads in German newspapers, claiming that renewables wouldn’t be able to meet 4% of German electricity demand. After the renewable energy revolution took off, in 2015, the pro-nuclear power “Breakthrough Institute” published an […]
– Are Li-Ion or Lead-Acid Batteries better for Home Energy Storage?
Are Li-Ion or Lead-Acid Batteries better for Home Energy Storage? Until recently the majority of solar-powered homes with energy storage used lead-acid batteries – particularly those that were entirely off-grid, but in the past few years that’s starting to change as an increasing number of companies are offering home energy storage systems using lithium-ion batteries. […]
– Tandem cells approaching 30% efficiency
Tandem cells approaching 30% efficiency Scientists at the Helmholtz Zentrum Berlin have taken back the world efficiency record for a perovskite/silicon tandem solar cell, achieving 29.15% with a device measuring 1cm². The record has been confirmed by Fraunhofer ISE, and according to HZB, this means that the 30% efficiency mark is within reach. A group […]
