[TRNSYS-users] PV Panels increase roof temperature ?

[Tushar Sharma]

Dear Sam

I think you could utilize the thermal component using Pv-t panels than just normal PV. Or else you can do some detailed cfd analysis for a portion of roof that interacts with PV under different operating conditions just to see which factors contribute to the thermal losses. Not sure if that's possible in trnsys.

Subject: [TRNSYS-users] PV Panels increase roof temperature ?

Dear community,

I'm wondering if the roof of the building I'm modelling is 70% covered of PV panels increases roof's temperature,

Let's assume 20% of solar energy is converted to electricity, the remaining 80% is thermal energy stored in the PV panels as heat and transmitted to the roof and the sky, thus increasing roof's temperature compared to a low absorption roof coating (cool roof without
PV panels) ? am I getting this wrong ?

Thank you!
