Abstract/Summary:


Floating PV emerges as an important segment in the global PV industry, with close to 2 GWp installed at the time of writing. A list of more-or-less documented benefits motivates the interest, investment and growth in the field. These include the increased access to areas near population centers, industrial sites and power plants, as well as potentially lower land, component and installation costs. In addition, many papers and reports stress increased production as a function of effective cooling of the PV modules as an important benefit. In this paper, we combine data from the available literature, thermomechanical modeling of specific floating and mounting solutions and configuration, PV systems modeling in PVSyst, as well as own temperature and performance measurements of floating PV power plants. We use the data as a basis for a structured and critical review of this for the industry very important issue. We will show that, although cooling resulting in a production increase of up to, perhaps even exceeding 10% is indeed possible for a commercial-scale floating PV plant, this depends strongly on the selected technology. Data from floating PV systems based on pontoons, platforms and supported membranes will be compared and discussed.
