Customer ServicePassive 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.
When the PV systems are implemented in an extreme environment, the PV cooling systems will be powered by the PV generators. By running water across the thin film of film of water, we can both reduce the reflection loss and keep the panel cooler. To adjust the temperature of the panel, we can use water cooling. 4.2.2.

The heat transfer model for a photovoltaic panel was simulated using Matlab software. The front surface temperature of the photovoltaic panel was simulated, and the results were validated by experimental data. The front surface temperatures of a no-load photovoltaic panel and a photovoltaic panel covered with snow were simulated respectively.
During the heating phase, the temperature of the front surface of the photovoltaic panel rises and reaches the melting point of snow (0 °C), causing the snow to begin melting. Absorbing the large amount of latent heat required for melting causes the temperature to drop slightly.
When the P.V. module heats up, its output decreases. This bump is directly related to the energy absorbed by the panel and is then transformed into heat and results in lower panel output, energy efficiency, performance, and the life of the panel. To avoid PV panel overheating and to keep panel temperatures low, cooling techniques can be utilized.
At the beginning of the melting process (τ 1),\ a peak appears in the temperature curve of the photovoltaic panel. During this phase, the temperature of the front surface of the photovoltaic panel continues to rise, and after the melting point of snow (0 °C), the snow starts melting.
