Due to COVID, SolarEdge has delayed its residential battery system and has seen a slow recovery for its commercial customers. But its Q3 reports were strong due to a surge in res sales for inverters. In 2019 SolarEdge held 60% of the US panel-level power electronics market.
Clean energy companies are confronting racism by issuing statements condemning it and donating to the NAACP. But it also requires changing the demographics re leadership, shifting internal company culture and promoting access to solar for communities of color.
Increases in temperature impact tandem perovskite/silicon solar cell performance due to voltage loss and mismatch between the two sub-cells. If one of the two-terminal tandem cells generates less current than the other there’s a mismatch and the device’s current is affected.
Can RE’s deliver year-round reliable power? Yes. How? Don’t store the power spill, learn how to use it in real time; solve the missing power problem by fueling gas plants with RE’s; understand and manage the fact that spills will be largely seasonal.
On Nov 4 the US formally withdrew from the Paris Agreement that set carbon reduction targets. Several US states and major corporations have vowed to uphold its stipulations. ACORE CEO states it means the US “is squandering global credibility and goodwill.”
More and more manufacturers are transitioning to minimal-flashing solar roof mounts to address the problems that come with prying composite shingles up to slide the sealing roof attachment under them. It started with tech from QuickBOLT, EJOT, and Zep and has grown.
SPW created a roundup of 17 US solar policy snapshots: only 1/5 of U.S. cities are on track to meet carbon reduction goals, Duke Energy plans to double renewable portfolio goal by 2025, and the NY Power Authority will look at how to transition natural gas peaker plants to clean.
Three solar companies pursuing philanthropy are Twende Solar (focuses on philanthropic solar dev), the Honnold Foundation (brings solar to NPs, provides grant funding and project management) and Solar Crowdsource (tech and services to promote Solarize campaigns).
2021 corporate renewable energy market predictions are for an increased interest in social justice, being 100% renewable and reducing Scope 3 emissions through supply chain programs. PPA portfolios will include storage. A desire to meet 2030 sustainability goals will drive innovation.
Solar+storage provides value by allowing for energy reliability during emergency power outages and helping the grid balance demand and generation during non-emergencies. Too much solar to the grid has sometimes meant switching off excess power flowing from farms.
