The objective of the Solion partnership is to develop an integrated energy kit able to be produced on an industrial scale for decentralized on-grid, residential photovoltaic (PV) systems.

The project will introduce large lithium-ion batteries into PV systems on the largest scale ever tested in Europe, said Saft. Lithium-ion technology is required in order to meet the need for 20 years’ battery life in demanding environmental conditions.

The 75 systems will be deployed in Germany and France. These trials will validate the performance of the system, its economic viability, the added value of energy storage in an on-grid PV system and the benefits for stakeholders.
