Increasing the efficiency of photovoltaic panels by watercooling

Today, the use of photovoltaic systems is increasing in the field of renewable energy in particular. The efficiency of the photovoltaic panels used is of utmost importance. One of the ways to improve efficiency is to cool the panels used during the energy production phase. In this thesis study, a PV panel with 100 watts output power was installed on a construction. Water for cooling panel, Data logger for the output current, voltage values and temperature measurements of the panel, and flow meter devices for measuring the flow rate of the water. In addition, a rheostat was used as a load. In these measurements, normal measurements were made first, then the panel was cooled and the current voltage and temperature values of the panel were measured. Then the voltage and temperature values are measured again when the panel is warmed up normally. The obtained data were arranged in the computer environment and necessary calculations were made.
