Solar PV panels convert sunlight into electricity through a process called the photovoltaic effect. (PV) and solar thermal – is the same. They absorb raw energy from the sun and use it to create usable energy. The amount of solar radiation on the earth surface can. A solar heating system, or solar thermal system, converts the sun's radiation directly into usable heat energy for residential or commercial purposes. The process of solar heat conversion implies using energy collectors - the specially designed mirrors, lenses, heat exchangers, which would concentrate the radiant energy from the sun and transfer it. Solar panels provide a sustainable way to generate electricity, which can be utilized to power electric heaters, enhancing energy efficiency and reducing reliance on fossil fuels.
