Testing floating PV with tracking systems
French water management agency Société du Canal de Provence (SCP) is planning an innovative floating project to test its combination with a solar tracking system. The 250 kW project was awarded a fixed tariff in a special tender for innovative PV projects held by The French Energy Regulatory Commission (CRE) in February 2018. The plant will be deployed on a water surface managed by SCP in Southern France.
