Photovoltaic power generation and energy storage in Western Europe

Is the solar PV sector on the brink of transformative growth?

The solar photovoltaic (PV) sector in Europe is on the brink of transformative growth as we approach 2025. With an accelerating shift toward renewable energy, solar PV is poised to play a central role in the continent’s energy transition.

How does solar power affect battery storage in the EU?

Years of strong solar growth and high gas prices have increased electricity price volatility across the EU, strengthening opportunities for battery storage. In turn, batteries can increase power demand at peak solar times, supporting solar revenues.

Will large rooftops unlock solar power in Europe?

Large rooftops still hold vast solar potential in Europe. Unlocking it will require more energy storage and greater system flexibility. This March marked the third month in a row that Europe broke a historic power generation record. According to Eurelectric, solar now accounts for over 10% of the continent’s electricity mix.

Which country generates the most electricity from solar photovoltaics?

In 2024, Germany was the country with the highest electricity generation from solar photovoltaics, amounting to more than 74 terawatt-hours. That is roughly one-fourth of the total generation in the European Union.

Is battery energy storage a solution to Europe's energy crisis?

Europe is at the forefront of decarbonisation efforts, with already achieved results and ambitious goals for the coming decades, particularly in the power sector. However, the greening of the European electricity system also requires increasing flexibility . Battery energy storage systems (BESS) represent a crucial component of the solution.

Could a 5% battery capacity ensure optimal integration of PV in Europe?

A 5% battery capacity level could ensure optimal integration of PV in Europe. The varying level of RES curtailment could be handled by 5% battery capacity. Country heterogeneity is observed in the optimal level of batteries. Batteries can ease the strong cannibalisation effect of PV plants.
