A Dutch-Hungarian research team has measured, for 12 years, the degradation rates of PV modules installed in an off-grid system located in Ghana. It found that the panels had an average annual decline in power yield of 3.19%.Scientists at Hungary's Szent István University and the Eindhoven University of Technology, in the Netherlands, have conducted a 12-year assessment of solar module degradation rates at an off-grid solar power generator located in Koforidua, in the Eastern Region of Ghana. The main goal of the research was to measure the levels of PV module degradation in hot, humid, tropical ...Den vollständigen Artikel lesen ...
