The literature provides examples, procedures, and relationships for determining the influence of operating temperature over the efficiency of PV panels, but most of them are related to the STC or NOCT conditions only . A feasible method to increase the efficiency of PV panels consists in using cooling solutions [14, 15].
The hot spot effect can cause solar panels to overheat locally, reducing their efficiency and potentially causing damage. Details are as follows: 1.Efficiency degradation: When hot spots occur in solar panels, the local temperature rises, which usually leads to a decrease in the performance of the solar cell as the temperature rises.
Deokar et al. employed an active cooling system for reducing the temperature of a PV panel and recovering the waste heat to dry onion flakes. Mild steel chips and thermal grease were applied at the back of the PV panel to act as a heat sink. A 16.1 °C temperature drop was recorded using this method.
Cooling is a critical issue in the design and operation of concentrated photovoltaic (CPV) technology, as high cell temperatures and non-uniform temperature distribution can cause current mismatching and hot spots on the cell, resulting in either reduced efficiency or permanent structural damage due to thermal stresses. Due to high cell temperature and non-uniform temperature distribution.
Owing to the low efficiency of conversion of solar energy to electrical energy,more than 80% of the incident or the striking solar energy heats the photovoltaic (PV) panel surface. This heating causes
