Abstract/Summary:


Floating Photovoltaic (FPV) has recently gained a large interest worldwide, essentially as a result of promoting unused land to generate electricity. Like ground-mounted PV projects, FPV feasibility is bound to the power production estimation. Considering a production gain of 0.4% per °C for silicium cells, in addition of cooler local climate over waterbodies, predicting the thermal behavior of PV modules through modelling system arises as a stepping-stone of the next FPV commercial stage. In that context, EDF has launched a floating structure with numbers of high-frequency sensors in order to catch the evolution of interesting physical parameters, contrasting with parameters encountered over ground-mounted structures. To support previous research under tropical conditions, six months of data have been gathered during a cold period of temperate area. Discernable cooling effects were less frequent and profited of lower magnitude in such area. In addition, waterbody physical behavior was highlighted as an important catalyst of module temperature behavior. Thus, global climate conditions emerged as a key factor of cooling effect estimation for FPV. Finally, predicting module temperature has been managed through existing thermal model including in the in-house 3D-ray tracing software PVNOV.
