Residential PV

The International Energy Agency (IEA) Photovoltaic Power Systems Programme (PVPS) has published a wide-reaching snapshot of the global PV market, covering installations, manufacturing, policy trends, and grid integration.

Ohm Analytics reported that the 2.3 GW of distributed generation, which includes rooftop solar, deployed in Q4 2023 marked the end of a long period of growth. Roth MKM warns that if a turnaround does not occur soon, residential solar could decline by 20% to 30% in 2024.

The Solar Energy Industries Association (SEIA) released an overview of the top states for solar installation last year.

Rooftop solar has the technical potential to serve 45% of electricity demand, based on 2022 demand levels, said a report from Environment America. As of that year, it served about 1.5% of electricity consumed.

The Massachusetts STAR program announced its fourth phase of program participants.

The 18th edition of the EnergySage Marketplace Report finds the residential solar segment in the U.S. is rocked by persistent inflation, the California NEM 3.0 and rising loan fees. Yet prices have fallen and consumer interest in storage is strong.

BloombergNEF says in a new report that developers deployed 444 GW of new PV capacity throughout the world in 2023. It says new installations could reach 574 GW this year, 627 GW in 2025, and 880 GW in 2030.

Today, it only represents about 1.5% of the electricity used. A report from Environment America shows how installed rooftop solar increased 1000% in the past decade, and how it has a long runway of growth ahead.

Also on the rise: 26% of battery storage systems have fire detection and suppression issues. Solar glass manufacturing comes to Georgia. And more.

Solrite Energy says its new power purchase agreement has more agreeable finance terms due to the ability of distributed solar-plus-storage to make money as part of a virtual power plant.
