One method to mitigate the solar radiation load is directed natural ventilation underneath the PV. Providing the module with an air gap that allows air to flow behind the module decreases solar panel temperature and increases the performance of BIPV. Heat is transferred by convection to the air and transported away by the airflow.
The unique properties of roofs, such as good sunlight incidence, good ventilation conditions, no redundant shielding, and flexible tilt angle for PV panels, are advantageous for solar energy harvesting.
