Current implementation of energy simulation for floating PV systems is based on research articles about floating solar.
First article analyses temperature model of PV modules in existing installations:
FLOATING PHOTOVOLTAIC MODULE TEMPERATURE OPERATION CHARACTERISTICS, Waithiru Charles Lawrence K., Chang-Sub Won, Dong-Chan Kim, Kwang-wook Kim, Bo-ram Kang, Gun-Hyun Lee, Ogeuk Kwon, Sumin Lee, Power Conversion Research Team, LSIS Corporation Korea, 36th European Photovoltaic Solar Energy Conference and Exhibition, Marseille, France 2019.
Second article analyses mismatch losses caused by water movement:
INFLUENCE OF WAVE INDUCED MOVEMENTS ON THE PERFORMANCE OF FLOATING PV SYSTEMS, Maarten Dörenkämper, Daan van der Werf, Kostas Sinapis, Minne de Jong, Wiep Folkerts, TNO-SEAC, 36th European Photovoltaic Solar Energy Conference and Exhibition, Marseille, France 2019.
In Prospect app, we are using definition of some kind of "general" floating system with some basic settings and properties. Thus results of calculation should be handled only as preliminary estimation because there are existing several types of floating system constructions (usually specifically selected according to local conditions) and we are not considering all of them. Later, when more research/knowledge/installations/data/validations will be available, we plan to introduce more specific types of systems.
