Photovoltaic thermal module
PVT modules produce electricity and thermal energy.
The generated electricity from PVT modules is about 15% to 20% compared to the standard Photovoltaic module аnd thermal energy is about 3 times higher than the power of the standard photovoltaic modules.
Most of the absorbed solar radiation in the photovoltaic is converted to heat (about 70-80%), a small part is reflected, and the rest is converted into electricity. As a result, the temperature of the photovoltaic cells increases. This effect reduces the efficiency of the photovoltaic.
In facade or slanting installations, thermal losses are reduced due to reduced cooling on the back of the photovoltaic and the module operates at higher temperatures.
This undesirable effect can be avoided with the PVT hybrid module (Figures b and c), where heat is removed from the fluid circulating PV modules, while maintaining satisfactory electrical efficiency.
The PVT modules are divided into two groups:
- Glazed: Photovoltaic modules with additional glass above the Photovoltaic module, which produce more thermal energy, and
- Unglazed: Photovoltaic modules without additional glass, which produce more electricity.
