PV, storage may allow 53% of European households to end reliance on grid

Leave a Comment / News / By

Thanks to PV systems and battery storage, millions of households in Europe are already partially self-sufficient. A German-Swiss research group has calculated the potential for European residential buildings to achieve grid independence with solar-plus-storage solutions. The team aimed to determine whether such homes could abandon the grid completely. They based their calculations on a database …
