Using machine learning and cheap satellite data to design rooftop solar power

Researchers have built a tool to use cheap satellite imagery – like Google Maps – to automatically create solar designs with a 91% accuracy rate.

Bifacial beats Trump’s tariffs

Federal trade authorities have ruled that bifacial solar modules are no longer subject to the Section 201 ruling, which currently apply a 25% tariff to most solar modules imported to the United States.

California is learning to trust 100% residential solar power

California utility PG&E has tested levels of residential solar power up to 100% penetration, and how to mitigate the effects of voltage and thermal overload via smart inverters and traditional transformer and circuit upgrades — with smart inverters shown to allow for up to 100% penetration at cost-effective pricing.

California’s solar power record setting season arrives

The state grid operator reported breaking 11 GW of instantaneous power from large scale solar on Saturday at 1.50pm. Just 20 minutes earlier, the CAISO grid was exporting a record 1.5 GW of electricity, and last Wednesday it hit 93% clean electricity for a moment.

Tesla, GAF, RGS and now Hanergy: will solar roofs finally heat up this year?

Hanergy displayed the newest rendition of its 18.7% Thin Film Flat SOLARtile in Australia last week as it gears up for the U.S. and global product launch later in 2019.

High-efficiency solar module upgrades from REC and Trina

REC Group has begun production of its residential N-Peak Black series, reaching up to 325 watts. Concurrently, Trina Solar has released four new modules within its Tallmax, Duomax, Duomax Twin and Honey series — some of which reach up to 415 watts.

DOE supporting cheap gallium arsenide, 30% efficient perovskite, and more

The DOE’s Office of Energy Efficiency & Renewable Energy has awarded $50,000 to 20 teams that advanced to the semifinal stage of the American Made Solar Prize. The teams will now have 90 days to design a proof of concept.

If bifacial panels can compete on price the (backsheet) choice is clear

Jinko Solar has launched a new bifacial solar module, with a clear backsheet manufactured by DuPont, to compete with standard glass-on-glass bifacial products, as well to create markets where bifacial might not have previously fit.

Enphase is making money again

The California-based microinverter maker posted $92 million in revenue in the final quarter of last year, and more than $106 million in cash as the company reported its first positive quarterly and annual operating income figures in years. Enphase is booked out for all of this quarter and seemingly into the late spring months too.

A blockchain trading solar power system in the real world

PowerLedger’s xGrid is a blockchain-based electricity trading platform that’s now being used in a Pennsylvania business park, in addition to Chicago, California, a large housing unit in Australia, plus a few more locations.
