Energy innovation is both time- and capital-intensive and heavily regulated. Because investors tend to be risk-averse when it comes to technological development, cleantech startups face a broad array of challenges that can impede their technology from making it to the marketplace. According to one prominent venture capitalist in the energy space, “If I have to put in $30 million to find out if the technology will work, it’s a no-go.”

Access to reliable electricity is essential for improving human livelihoods and is a prerequisite for economic development. Yet hundreds of millions of people lack access to a stable supply. While access to electricity is essential, the sector is also the leading driver of greenhouse gas emissions globally

The National Renewable Energy Lab is building the first national database of albedo, or reflected light values, to help model the performance of bifacial solar panels, the highest-yield type of panel in the industry thus far. The database is an outgrowth of a large field test of bifacial panels at the lab, which includes a variety of fixed-mount and tracker systems and a mix of bifacial panels from different manufacturers

Hawaiian electric utilities have been forcefully de-linking residential rooftop solar generators at peak hours for several years, but the installation-discouraging practice may fade as refocused utility-scale solar+storage contracts come into effect. Beyond Hawaii, these new contract types, which shift curtailment risk away from the solar owner, also may help California avoid an increase in the curtailment of solar flowing onto its grid

Researchers at Stanford University have managed to create a map of almost every solar rooftop in America, pulling together satellite images and extracting the information. The DeepSolar data, based on Google’s Inception V3, is the first publicly available, high-fidelity solar installation database in the contiguous United States, the researchers say
