In the U.S., PV module efficiency (median values) rose from 12.7% in 2002 to 18.4% in 2018, much of it in the last decade and a full percentage-point increase in the last year alone. The best modules are even more efficient, says John Rogers at the Union of Concerned Scientists. Improvements have come from manufacturing processes and cell architectures, and the increasing share of more-efficient mono-crystalline technologies: up from 40% in 2016 … [Read more...]
Solar energy is green. Solar panels are not. AI can revolutionise their design
Solar panels are manufactured at 2,000˚C, a temperature so high it requires fossil-fuel power. They are also made using rare earth elements, the supply of which has both capacity and political issues. A new and global project is using artificial intelligence (AI) to rapidly create new designs with new materials that can make their manufacture greener and cheaper. The new designs may even bring their manufacture back to your home country, says … [Read more...]
Solar panels replaced tarmac on a road. Here are the results
Using roads for solar energy generation is one of those ideas that makes engineers frown but seems to capture the public imagination, with an Indiegogo fundraising campaign for the concept pulling in almost $2.3m in 2014. But now the idea is being put into practice it appears the engineers may have been right all along, according to Dylan Ryan of Edinburgh Napier University.
