I have gone through a research paper stating that if two semi-transparent PV panels were place one upon one to form two layers with some gap between them. And still the lower panel can generate upto 30% of what the upper pannel is generating. I want to study this condition. Also with case of dust layer. Case of Water layer on top of panel which allows a dust free panel but also a coolent. can I study this phenomenon in pvsyst?
