PV is now a vital part of the global power supply; Wood Mackenzie data indicates that by early 2026, cumulative worldwide PV capacity had reached nearly three terawatts. This growth creates new challenges for the power grid and for market mechanisms, such as negative prices during peak periods and a rise in redispatch measures. All of this makes large-scale storage systems a game changer because they store surplus solar power and later feed it back into the grid, contributing to more flexibility, better grid integration and more efficient utilization of the renewable energy system.

Stationary storage devices are becoming more and more profitable. According to BloombergNEF, the price of stationary storage plunged to 70 US dollars per kilowatt hour in 2025 - this is the largest drop across all battery segments. The price reductions were driven by overcapacities in cell manufacturing, fierce competition between Chinese manufacturers and the expanding use of lithium-iron-phosphate (LFP). Stationary storage devices can be combined to form hybrid PV systems, making them an integral part of the European - and the global - energy transition. They boost system stability, enable new business models and strengthen the profitability of projects under changed market conditions and new subsidy rules.

New financing models: CFD

In many EU countries, CFD models have started to replace conventional feed-in tariffs. They secure yields for project developers, stabilize consumer electricity prices and include clawback features for refunding excess revenues. The system is about to be changed in Germany, too: The government-approved feed-in tariff under the Renewable Energy Sources Act (EEG) is going to be discontinued at the end of 2026. Market players fear that without the EEG feed-in tariff, securing loans for new projects is going to become more difficult, and are calling for reliable framework conditions for secure investments in Germany and across Europe.

Meet an international crowd at Intersolar Europe

Hybrid PV power plants and new financing models will get much attention at Intersolar Europe 2026. The Intersolar Europe Conference starts on June 22, offering a high-level kickoff event for the exhibition, featuring renowned experts, strategic discussions and exclusive insights into market trends. From June 23-25, the practical implications of these topics will be discussed at the Intersolar Forum, while exhibitors will be presenting concrete solutions in the exhibition halls. Intersolar Europe will take place as part of The smarter E Europe, Europe’s largest alliance of exhibitions for the energy industry, alongside three other exhibitions, ees Europe, Power2Drive Europe and EM-Power Europe. More than 2,800 exhibitors and over 100,000 visitors from all over the world are expected to attend in 2026. Intersolar Europe is organized by Solar Promotion GmbH and Freiburg Wirtschaft Touristik und Messe GmbH & Co. KG (FWTM).
