Electrek Green Energy Brief: A daily technical, financial, and political review/analysis of important green energy news.
40% of U.S. Homeowners Interested in Bundling Solar Power With Electric Utility Bill – “Bundling solar with energy services received the most consumer interest—40% of U.S. homeowners in broadband households are interested in bundling solar power purchasing with their electricity bill.” Over 50% of U.S. broadband households would purchase a smart device to manage energy consumption during TOU peak hours. The first quote here – 40% of broadband households wanting solar is a huge opportunity for the electric utilities to make money off of a lot of people. A chance to stay relevant. That second item could be a home battery system – lots of people wouldn’t mind throttling house hardware to take advantage of pricing disparities. Maybe batteries at home and solar on the grid is a big subset of buyers.
Proposition of an Environment Friendly Triple Junction Solar Cell Based on Earth Abundant CBTSSe/CZTS/ACZTSe Materials – The maximum obtainable efficiency is calculated to be 36.04% with 2.73 V open circuit voltage. Love base research. Earth abundant materials and a potential 36% efficiency. Anyone actually dealing with a real triple junction product in the world?
Yingli Green using bifacial modules in 100MW ‘Top Runner’ project – Data shows that, since the grid-connection of the Datong 50 MW ‘Top Runner’ project, which utilized PANDA Bifacial panels, its monthly energy yield is up to approximately 17% higher than typical multi-crystalline solar plants. 100MW of higher efficiency solar panels. This is why we see all of China upgrading their hardware to PERC and bifacial and mono – if the manufacturers want to sell their hardware into government supported programs, you gotta sell the high quality, high-efficiency product. Cool to see a 17% increase in production from bifacial solar panels – I’d like to know more data about how the panels we laid out, land composition, etc.
Orsted bonds raise €1.25bn – The €500m bond, which is listed on the Luxembourg Stock Exchange, was five times oversubscribed. The €750m security is listed on the London Stock Exchange and was 2.3 times oversubscribed, Orsted said. They’re building the largest wind farms on the planet. They need a lot of money. If they can go to the bond market to finance a few billions for a few GW of floating wind power, then we’re going to see wind power get developed at much faster and cheaper rates.
The difference between 300W monoPERCs and 270W polysilicon is only 7¢/W. This 300W panel is 18.3% efficient. Not bad – but it’d be real nice to see the solar cell/solar panel efficiency get closer.
Keystone Pipeline leaked. Almost a quarter million gallons of oil. Apparently, that amount of oil is about equal to what 7 drivers would use in their lifetime. Poured over farmland.
