The thickness of the thermal insulation was varied in order to find a minimum thickness sufficient for suppressing the heat losses and for the simulation of roof integration. The module-dependent coefficients for the Faiman model for the module temperature depend on the back-side heat losses. A correction for roof integration is proposed. This model allows the calculation of the maximum temperatures reached for given climatic situations (irradiation in plane of array, ambient temperature, and wind speed).enphotovoltaisches ModulSysteme und ZuverlässigkeitPhotovoltaische Module und KraftwerkeServicebereicheGebrauchsdauer von Modulen und MaterialienPV-modulesmodule temperatureintegrationSolarthermieOptikPhotovoltaikSilicium-PhotovoltaikfeedstockKristallisationwafering621journal article
