This is the simplest way of cooling PV modules, so it is very popular. This method increases the energy efficiency and cost-effectiveness of the system with a limited investment. Passive cooling with air is the cheapest and simplest method of removing excess heat from PV panels. In such a solution, the PV modules are cooled by natural airflow.
1. PV panels cooling systems Cooling of PV panels is used to reduce the negative impact of the decrease in power output of PV panels as their operating temperature increases. Developing a suitable cooling system compensates for the decrease in power output and increases operational reliability.
Proper cooling can improve the electrical efficiency, and decrease the rate of cell degradation with time, resulting in maximisation of the life span of photovoltaic modules. The excessive heat removed by the cooling system can be used in domestic, commercial or industrial applications.
Cooling tubes can increase the efficiency of power production by more than 13% and decrease the temperature of PV panels by 10–25 °C.
