In the marking field, solar electrical energy must be stored, because consumption and production occur within a different timeframe at the same time as production varies according to climatic conditions.
To ensure continuous nocturnal operation at the desired power level, the stored energy must meet the desired consumption but also provide a reserve for periods when sunlight is insufficient to provide a complete recharge. This is the challenge that the GEOLED technologies successfully took up.
The color codes represent the average duration of nocturnal operation in France (select the month to be displayed), given a brightness of 5 lumens of white light under Geoled-recommended installation conditions.
