Up through the 1970s, the US Navy and others supported development of solion devices for sensitive sonar and seismic applications, and a number of patents were filed.

These 2 PV system integrators will produce the other components and will assembly the SOLION product (battery + inverter + system management).

The objective of the SOLION partnership is to develop an integrated energy kit able to be produced on an industrial scale for decentralised on-grid, residential PV systems.

However, early solion devices had a number of serious problems such as lack of reproducibility and poor linearity, and practical production of devices was abandoned in the US and progress languished for decades.

SOLION has been recognised by the Eureka/Eurogia and Tenerrdis programmes, and is supported by the French Ministry of Economy Finance and Employment (DGE) and the German Ministry of Environment (BMU).

PARIS, August 28 /PRNewswire-FirstCall/ -- Saft, Conergy and Tenesol have announced the launch of SOLION, a Franco-German project dedicated to the development of a new concept in energy conversion and storage for grid connected photovoltaic (PV) systems.
