The choice of solar panels must match the size and area of the house. This is because, if you choose a component that is not the right size for your roof, then even if it works well during the day, it won’t be what your roof needs.
Solar panels can be square or round. Since the panels themselves are a larger component, they can be used on larger roofs. Installing solar panels on a smaller roof also has a better chance of gaining power output.
Solar panels need to be mounted on the roof to work properly, and need to be fixed above a certain height to work properly. This is one of the reasons why we have to consider mounting brackets.
