Germany has surpassed the halfway mark in its legally mandated target to double solar power capacity to 215 gigawatts (GW) by 2030, according to new data released by the Federal Network Agency.
As of mid-2025, the country’s total installed photovoltaic (PV) capacity stands at approximately 107.5GW, enough to meet about 15% of national electricity demand.
While the milestone reflects substantial progress, the German Solar Industry Association (BSW-Solar) cautioned that the pace of expansion has slowed in recent months, potentially putting the 2030 target at risk.
“There is no way around a stronger expansion of photovoltaics and storage systems in terms of climate and energy policy,” said Carsten Körnig, managing director of BSW-Solar. “The current heat wave and increasing climate damage make this painfully clear.”
BSW-Solar reported that over five million PV systems are currently in operation across rooftops, balconies, and open spaces nationwide. The association urged the federal government to accelerate efforts to dismantle remaining market barriers, including securing EU state aid approval for the long-delayed solar policy package.
Körnig highlighted the economic advantages of solar power, calling it “the cheapest form of electricity globally” and noting its growing role in reducing energy costs for both households and businesses.
The group also pressed for faster implementation of digital grid connection procedures and an expansion in battery storage. Current capacity is estimated at around 20 gigawatt-hours (GWh) across two million systems, but projections indicate that 100 to 150GWh will be needed by the end of the decade.
To meet that target, BSW-Solar said full enforcement of storage-related provisions in the coalition agreement—specifically the building law privilege for storage systems—will be required.
