Temperatures higher than 25 °C and 30 °C occurred on 2 fewer days when using the green energy roof than when using the solar energy roof. The mean temperature decreased by approximately 0.4 °C when a green roof without plants was adopted. Table 12 Solar module temperatures.
The back panel temperature of the solar panel is similar to the roof temperature for the exposed roof. However, since the roof surface underneath the PV panel is shaded its temperature is significantly lower than for the exposed roof.
Consequently solar PV has indirect effects on roof heat transfer. The effect of rooftop PV systems on the building roof and indoor energy balance as well as their economic impacts on building HVAC costs have not been investigated. Roof calculator models currently do not account for rooftop modifications such as PV arrays.
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). The optimal solar panel operating temperature is 25°C (77°F) under standard test conditions.
