This report uses data from the EIA to analyze solar and wind capacity and generation over the past decade (2014 to 2023) in all 50 states and the District of Columbia. Recent data are compared across states and against historical figures to show which states have led growth in.
With a solar electric system, you work on the power source itself (the PV panels or associated wiring)-this is fundamentally different than working on a 'safed load' and you must keep this in mind. Even low light conditions can create a voltage potential that can lead to a.
Over the past decade, the cost of solar panels has decreased globally by 90%, now being under $0. Conversion efficiency improved from 1-2% to 22% within the past century, reducing manufacturing and installation costs.
VDE Americas and RETC, part of the VDE Group, today introduce the hail resiliency curve (HRC) test that simulates real-world hailstorm conditions where solar panels may face numerous impacts from a range of hailstone sizes and wind speeds during server storms.
Solar industry news: Mounting, inverter, PV module, tracker and energy storage trends; net metering regulation; financing, buying trends and more. The Hawaii Public Utilities Commission (PUC) has given its stamp of approval for the Kaawanui Solar and energy storage.
California's rooftop solar policy is under renewed scrutiny. In August 2025, the California Supreme Court ordered a lower court to re-examine the state's controversial "NEM 3. 0" rules, which slashed compensation for solar customers feeding energy back to the grid.
Developers added 12 gigawatts (GW) of new utility-scale solar electric generating capacity in the United States during the first half of 2025, and they plan to add another 21 GW in the second half of the year, according to our latest survey of electric generating capacity.
IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a "kill switch" scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.
