[esp-r] Re: PV generation, winter's power >> summer's?

[Geissler Achim]

... check the "performance of PV vs. Cell temperature" of the model. Performance of (standard) PV modules generally deteriorates with rising temperature
... what is the tilt of the PV? Vertical? A vertical surface may receive similar amounts of radiation in winter for locations "close" to the equator
... integrate the actual radiation received on the corresponding surface for each of the intervals of interest to get an idea of what really to expect

Achim
