Utilities Bid To Own Rooftop Solar Even As They Oppose It

July 15th, 2019 | by John Farrell

Four years have passed since ILSR’s initial report on utility-owned rooftop solar, and this 2019 update shows small growth but some potentially large repercussions. This update rehashes the costs and benefits, updates the progress of the four initial programs, highlights a few new programs, and discusses the wider implications


Ciel et Terre Turns To PPA For California’s Largest Floating Solar System

May 23rd, 2019 | by Charles W. Thurston

French floating solar specialist Ciel et Terre has begun installation of 1.78 megawatt floatovoltaic technology system at what it calls the largest floating solar system in California. To finance this project, the company has utilized a 25-year power purchase agreement for the first time, providing a lifetime savings of $4 million for the Town of Windsor


Cleantech-Focused Innovation Organizations: More Money, More Resources, Faster Time To Market

May 23rd, 2019 | by Guest Contributor

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.”


NREL Builds First Solar Database For Bifacial Albedo

February 18th, 2019 | by Charles W. Thurston

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


San Diego Has Vast Solar Parking Lot Potential

January 18th, 2019 | by Charles W. Thurston

San Diego has an untapped 500 megawatt solar potential at commercial sites within the city, with parking lots representing three-quarters of the total, according to a new survey by the Clean Coalition.


Rooftop Solar Curtailment To Ease With Refocused Hawaii Energy Contracts

January 7th, 2019 | by Charles W. Thurston

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


Stanford Maps 1.47 Million Solar Roofs in America

December 19th, 2018 | by Charles W. Thurston

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


EVs, Aerospace, & Wearable Solar Foster Power-to-Weight Advances

November 30th, 2018 | by Charles W. Thurston

Advances in thin-film and other new solar technologies are expected to be driven by the demand for lightweight, high-power solutions in the EV, aerospace and wearable solar markets, reckons Matthew Reese, the author of a new study on the evolution of the technology
