Net PV capacity additions in the first half of 2026 totaled 7,931.1 MW—roughly on par with the previous year. However, the mix has shifted: For the first time, ground-mounted systems accounted for more capacity than all rooftop systems combined, while the number of new installations plummeted by 18 percent.

In 2025, the exchange price was below zero for 573 hours. How often do negative electricity prices occur, when exactly—and why it is not the exchange figure that counts for revenue calculations, but rather the figures reported by the transmission system operators.

Co-location combines a PV system and battery storage behind a single grid connection—resulting in a project IRR increase of approximately 29% due to shared infrastructure. An overview of technology, tax, and incentives for 2026.

Italy’s subsidy framework has been back in place since August 2026: The FER-X Decree allocates 37.15 GW, and the strike price for photovoltaic power in the auctions is 80 euros per MWh. The application deadline for the first round is September 30, 2026. What this means for German investors—market, subsidies, permits, taxes.

What will the feed-in tariff be in 2026? Since August, the rates have been 7.70 ct/kWh (partial feed-in) and 12.22 ct/kWh (full feed-in). Here are all the rates by power class, trends since 2000, and the implications of the 2027 EEG reform for investors and businesses.

In 2025, solar power in Germany generated more electricity than lignite for the first time: approximately 87 TWh from solar versus 67 TWh from lignite, ranking second in the electricity mix behind wind. What this shift in the trend means for PV investors.

On January 22, 2026, a new market for instantaneous reserve capacity was launched in Germany. For the first time, battery storage systems can participate in this system service and thereby generate additional revenue. What this means for PV investors—opportunities, risks, and specific figures.
