**6.2 Cooling and cleaning mechanism**

The PV system's output dropped as the panels' temperature climbed over 25°C. Dirt on solar panels might have a negative impact on their performance. In order to reverse this declining trend and improve field performance, the solar panels' surfaces must be cleaned and cooled in some way. A tiny sprinkler mounted in front of the system is used as a cooling mechanism that could improve the system performance by 7–9%.
