The temperature on the back of the photovoltaic panel is higher than that on the front

The arrangement of PV cells into a module changes the flow of heat into and out of the module. This increase in the temperature causes a lowered output voltage for the PV module. It's important to note that there are different temperature coefficients for. . The panel's degree of heat is usually higher due to direct solar radiation and limited cooling. This implies a reduced output. . In real-world conditions, solar panels typically operate 20-40°C above ambient air temperature, meaning a 30°C (86°F) day can result in panel temperatures reaching 50-70°C (122-158°F). [pdf]
