PV-COMPARE: Direct Comparison of Eleven PV Technologies at Two Locations in Northern and Southern Europe

摘要

Two identical 6.2 kWp arrays have produced 4,884 and 8,050 kWh of energy per year in Oxford, UK and Mallorca, Spain, respectively. Multi-junction amorphous silicon and copper indium diselenide technologies give the highest returns of energy per peak power. Amorphous silicon and CIS have good spectral response to blue wavelengths, and consequently operate more efficiently under overcast conditions. Amorphous silicon also performs well at high insolations because its large band gap renders it less susceptible to temperature effects. Crystalline silicon technologies perform relatively better under the lower temperatures found in the UK.
