Energy Yield Prediction of Amorphous Silicon PV Modules Using Full Time Data Series of Irradiance and Temperature for Different Geographical Locations

For several reasons, amorphous silicon is expected to be the preferred technology for hot climates: low temperature coefficients for maximum power, prevalence of annealing effect over light induced degradation, better matching of the solar spectrum due to air mass effects and smaller fraction of diffused light in comparison to direct one. An empirical method of the energy yield prediction of the amorphous silicon technology using full time series of irradiance and temperature for different geographical locations was developed, validated for a roof integrated PV system and a free mounted triple junction amorphous silicon module and simulated for different sites in Europe and Africa.
