A Guide to Floating Solar Photovoltaic Systems
It is believed that the first floating photovoltaic (FPV) system was installed by MIRARCO, a non-profit research firm, in 2008 by mounting ground-based PV systems on pontoons in a tailings pond near Ontario, Canada. The first utility scale FPV system was called SolarSea in the Maldives and was constructed in 2014 by the Austrian company Swimsol. The first US installation of an FPV system was at the Miami International Airport in 2020 by Ceil and Terre. By the end of 2018, FPV installations reached 1.3 gigawatt-peak (GWp) of total installed global capacity. These systems have been shown to increase energy yield, reduce evaporation, and in certain cases improve water quality in comparison to land-based PV systems. FPVs reduce the need for land resources for solar power generation. As a result, several densely populated countries are considering large-scale FPVs to support their growing energy demands.
At some large hydropower plants, covering 3-4% of the reservoir area with FPVs could double the estimated capacity. Combining the solar and hydropower can smooth the variability of the solar output while optimizing use of existing transmission assets, creating a synergistic benefit in countries where grids are weak. Challenges remain, such as a short track records, uncertainty about costs and environmental impacts, and the increased complexity of designing, building and operating on water.
This course introduces the student to floating solar photovoltaic (FPV) systems and goes into detail about the steps involved in every phase of project development. It also compares these steps and design considerations to those involved in land-based PV projects, and offers current case studies and examples of FPV applications around the world.
This course is based on the publication, World Bank Group, ESMAP and SERIS, 2019. “Where Sun Meets Water – Floating Solar Handbook for Practitioners”, Washington, DC World Bank.
