Welcome to
Reiner Lemoine Institute


We are an independent non-profit research institution working towards a future with 100 % Renewable Energy in our three research units Transformation of Energy Systems, Mobility with Renewably Energy and Off-Grid Systems. For more than 10 years we have conducted applied research to give scientific support to a long-term energy transition.

The institute is supported by the Reiner Lemoine Foundation. Reiner Lemoine was a pioneer in the field of renewable energy. While others were thinking and talking about alternative forms of energy, Reiner Lemoine took the lead and founded, amongst others, the solar companies SOLON and Q-Cells.
