Solar heating

Solar heating is a way of using the Sun's energy to heat up air or water. It works by using something called a solar panel (also known as a photovoltaic panel) to collect the Sun's energy and turn it into heat. The heat then gets transferred to a container like a storage tank where it can be used to warm things like your home or buildings. It is a great way to use the Sun's energy for free, as it does not produce any pollution and it does not use any fuel like gas or oil.
