Abstract
The high cost of photovoltaic modules motivates the use of reflectors to increase the electricity production. The system geometry of static low-concentrating PV systems for building-integration with parabolic aluminium reflectors was optimised for maximum annual electricity production. The optical efficiency of systems with different geometries was calculated from short-circuit current measurements on thin film modules and the annual electricity production was simulated. An inclination of the reflectors’ optical axis of 35°, resulting in a concentration ratio of 4.65, showed the highest electricity yield per cell area, 120 kWh/m2 cell area, 72% higher than for a vertical module without reflector.
