Abstract

A study of leakage currents in Photovoltaic (PV) modules has been shown to be effective in early detection of design, material, as well as process flaws. Corrosion has been found to occur in some old-generation a-Si:H PV modules during accelerated testing under damp-heat and under high voltage bias conditions. PV systems with progressively higher voltages are being built especially in Europe so as to derive the benefits of higher voltage operation. It is, therefore, essential to carry out acceleration testing at considerably higher bias voltages in hot and humid climate so as to detect possible design, material and process-induced weak points in PV modules.
