Ageing solar parks are quietly losing value. Falling injection prices, more negative hours, support schemes running out. There's a second act in them. Take the 6.4 MWp park in Tertre. It has injected fully into the grid for years. Like many installations from that period, it was built for one task: produce and inject. The market it operates in has changed since, and the value of pure injection is under pressure. A 1 MW / 2 MWh battery was added to the same site. For months, generation and storage ran on separate tracks. The panels injected. The battery handled imbalance and FCR on its own. Two assets, two separate stories. Since last month, they work as one system. An energy management system decides on its own, hour by hour, which value the assets deliver: imbalance, FCR, or shifting energy to a better moment. The market sets the choice, the system carries it out. That moves an installation from separate revenue streams to one integrated whole that delivers more than the sum of its parts. For owners of existing solar parks, that shift matters. Especially those watching their original support period expire and wondering what the asset is still worth afterwards. Storage and active steering, with or without repowering of ageing panels, can turn it into a strong business case again. We design, finance, build and operate this as a service. No CAPEX. Do you own a solar park with declining returns? Let's look together at what storage and steering can add.
