Abstract: Carbon dioxide emissions have risen sharply in recent years, and the solution is to switch to carbon-free energy sources. One of the renewable technologies with bright prospects is solar PV. To maximise performance, increasing the amount of irradiation and maintaining the operating temperature is required. This study suggests an easy modification for an existing solar PV system, with a combination of a single, dual aluminium reflector and spray cooling. NIT Kurukshetra is the site of the present investigation; a water spray recirculation system has been designed. Experiments were run comparing the performance of a reference configuration to those run with a single and a dual reflector. When using just one reflector and intermittent cooling, the average power generation efficiency increase was 5.74% compared to the reference system and when using a dual aluminium reflector with intermittent cooling it was 10.53%. An economic analysis and exergy analysis of the two methods and their comparison have also been made.
