A solar air conditioner can combine solar as well as electricity or only solar power, depending on the type. In simple words, it takes energy from the Sun and uses it to power your AC to cool your space or keep it warm. There are two different types of solar air conditioners, hybrid solar air conditioner and 100% off-grid solar air conditioners.
Hybrid solar air conditioners are connected to solar panels and the power grid, switching between the two through a smart system, so that they never run out of power but take full advantage of any solar energy available in the environment.
100% off-grid solar air conditioners are connected to a sufficient number of solar panels so that they can run continuously on solar power, using no grid power at all.
Solar panel is a device that captures the power of the Sun. It converts the Sun rays into electrical energy. This energy can then be used directly or stored in a battery. This is known as DC power. A solar-powered air conditioner then uses this DC power, either directly as DC or after conversion into AC (using an inverter), to cool your space or keep it warm.
