The U.S. solar industry installed 43.1 gigawatts-direct current (GWdc) of capacity in 2025, down 14% from 2024. GWdc is the nameplate rating of projects before they connect to the grid through inverters, which convert direct current (DC) to the alternating current (AC) our grid uses. Two elements lower DC ratings to AC ratings. First, inverter losses account for around 4%. More importantly, solar...

Xcel Energy and Google recently announced a monumental clean energy agreement to power a new data center in Minnesota.
