Lab-made perovskite solar panel loses 25% of efficiency over 9-month period
Researchers have studied a perovskite solar panel array with little generation loss due to high temperatures, and better performance than expected.
Solar on US canals moves closer to reality
Project Nexus expects to break ground on a canal-top solar project in the fall, with completion targeted by the end of 2023.
Aluminum-sulfur battery for small-scale storage at $8.99/kWh
Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.
GAF Energy breaks ground on US solar roofing factory
GAF Energy said its new production facility in Georgetown, Texas, will create hundreds of renewable energy jobs.
Predicting solar power output with limited data sizes
Researchers in Greece have developed three different transfer-learning strategies for solar power forecasting. The techniques are based on a stacked long short-term memory model, which is a kind of recurrent neural network that can learn order dependence in sequence prediction problems.
Sri Lanka launches tender for 100 MW solar park
The Sri Lankan authorities are seeking a developer to build a 100 MW solar project on a build-own-operate basis, in addition to a new 132 kV transmission line. The facility will sell power to the Ceylon Electricity Board under a 20-year power purchase agreement.
Grid-forming inverter to stabilize microgrids
Toshiba has developed a smart synchronous inverter that stabilizes power fluctuations in microgrids. The Japanese company said it has tested the device in combination with PV and battery storage.
Airbus solar airplane crashes after 64 days of flying
The 25-meter-wide Airbus solar drone, which is remotely controlled by satellite, is entirely covered with PV modules.
Australian ‘renewable energy zone’ attracts 17 GW of project proposals
Renewable energy investors have proposed more than 40 new clean energy projects, or about 17 GW of capacity, for a coordinated “renewable energy zone” to be built in New South Wales, Australia.
Hydrostor develops 500 MW/4 GWh compressed air storage project in California
Hydrostor has selected an engineering company to provide front-end studies for a 500 MW compressed air energy storage project in California.
