As we have already seen, there are two types of solar panels: thermal panels and photovoltaic panels.
The thermal panels are used to convert solar energy into hot water or heating for the house.
The sun's rays are absorbed by the panels and converted into heat through the heat transfer by radiation. This thermal energy is then transmitted to the water heater or heating circuit by a pump.
Photovoltaic panels are a bit more complex since they must transform the sunlight into electricity. Each panel shall be set up of several photovoltaic cells connected together. Each cell sends a given voltage (0.5 to 0.6V.) Regardless of sunlight. It lists three types of photovoltaic cells: monocrystalline cells, polycrystalline cells and amorphous cells. Their costs are decreasing, but therefore their well. Yields
The electricity produced by the panels can be estimated by multiplying the cell voltage by the intensity, linked to the sunshine. You will therefore understand, the more the sun shines, the more you produce Watt!
