Theoretical and experimental analysis of a floating photovoltaic cover for water irrigation reservoirs

摘要

The article presents the main design features and photovoltaic requirements of a FPCS (floating photovoltaic cover system) for water irrigation reservoirs whose purpose is to reduce the evaporation of water while generating electrical power. Also, a summary of installation costs and relationship with the yield performance is deeply analyzed. A prototype of 20 kWp was implemented, and given the success of the results observed, the whole surface reservoir was covered (4490 m~2 and 300 kWp). The paper analyses the first electricity productions of the system and from these data the CO_2 balance of the facility is calculated.
