6 FAQs about [What is the function of the high temperature strips of photovoltaic panels]
Does high temperature affect the performance of PV panels?
This high temperature causes the cell surfaces to develop lower electrical efficiency and corrosion, resulting in the reduced service life of the PV panels. Empirical and theoretical studies have shown that high temperature is inversely linked to the PV module power out, and the PV panels performed better when a cooling process is applied.
