Solar capture rates fell in Europe in March 2025 says Pexapark

Pexapark, a Zurich-based energy analytics firm, has reported sharp declines in solar capture factors across key European markets in March 2025. According to Pexapark, Germany’s capture factor fell from 0.77 to 0.53 due to 17 GW added capacity and generation rising from 4.5 TWh to 6.6 TWh. France, Greece, and the Netherlands were also affected, with capture factors dropping between 13% and 17% year-on-year. As per the report, Spain remained stable at 0.49 because solar generation stayed near 3.1 TWh despite 5 GW new capacity. Pexapark said growing solar output is reducing market value during peak hours, and current battery storage deployment is not yet sufficient to absorb the excess supply or support price stability.
