Abstract: The performances of one photovoltaic and two thermal panels during several months of outdoor exposure have been measured. For the photovoltaic panel, the average degradation rate of the efficiency was 7% per month, whereas, for the thermal panels, the average degradation rate on the optical efficiency ranged from 2·8% to 7% per month for this maritime-desert-subzone type of environment.
