Air-based cooling technique PV panels can be cooled by forced and natural flow of air depending on active and passive cooling. Passive cooling is performed by the natural flow of air on a heated surface. While Active cooling is performed by the forced airflow in channels, heat sinks, and fins are attached to the back side of the panel.
Passive cooling of photovoltaic panels can be enhanced by additional components such as heat sinks, metallic materials such as fins installed on the back of P.V. to ensure convective heat transfer from air to panels . The high thermal conductive heat sinks are generally located behind the solar cell.
Excessive heat build-up is an enemy of solar modules. It makes them work harder, degrade faster and produce less energy. Cooling down your solar panels is extremely important, and it can boost the output of your solar PV system a great deal.
