For years, French homeowners with solar panels could bank on selling their excess electricity back to the grid, adding a tidy sum to the family budget. But that’s a thing of the past. The collapse of feed-in tariffs for surplus solar power—plus the axing of self-consumption bonuses—has fundamentally changed the economics for photovoltaics in France. Put simply: it’s now smarter to use your own solar energy or store it for later, rather than counting on selling it off.
According to data from Enedis (France’s electricity distribution operator), solar installations equipped with storage systems shot up by nearly 167% between Q4 2024 and the end of 2025. In fact, their numbers have more than tripled in just three years. While battery-equipped systems still make up just around 8% of the total self-consumption market by volume, they’re by far the fastest-growing slice of France’s solar scene.
This acceleration is partly thanks to a new generation of battery storage solutions, like those developed by Zendure. Gone are the days of complex hybrid inverters and heavy-duty electrical work. These new low-voltage modular batteries plug directly into a standard power outlet, meaning no mandatory electrician is needed for installation. This opens the battery game to renters and small-installation owners who, until now, were locked out by the cost and complexity of traditional solutions.
What’s more, Zendure is betting big on artificial intelligence to squeeze every last cent of value from storage. Its ZEN+ HOME ecosystem—built around the ZENKI AI assistant and their proprietary ZenPulse model—constantly tracks solar production, household consumption, and electricity prices. The result? It can anticipate your energy needs 24 hours ahead, then automatically trigger the smartest charge-discharge cycles.
The PowerHub, described as the heart of this ecosystem, manages everything: from solar panels and batteries to grid connection, backup supply, and even smart home devices like heat pumps or electric vehicle charging stations.
Come August 2026, Zendure raised the bar again with a new partnership with French energy supplier Sobry. Now, users of certain SolarFlow models can activate a variable-rate electricity subscription—straight from the app. The benefit? You charge your battery when power is cheapest, and use it when rates soar. According to Zendure, a household equipped with solar panels and an 8 kWh battery could save up to €625 (roughly $675) per year, without needing to touch a thing.
The lesson? If you thought solar’s game-changing days were behind us, think again: smart storage (and a dash of clever software) is rewriting the rules once more.
