Why are solar panels put on the roof?
The main components are the solar panels which will be located on the roof area, and the inverter which will be located within your house or attic. The solar panels convert the light into DC electricity, and the inverter converts this DC electricity into AC electricity for use in your home.
Do solar panels have to be on your roof?
Because they’re not dependent on your roof, ground-mounted solar panels are set at the perfect angle to optimize energy production. … Most installers offer a ground-mount system option, and the cost of standard ground-mounted solar is comparable with a rooftop solar energy system installation.

Is it cheaper to install solar panels on the ground or on the roof?
Ground-mounted photovoltaic arrays typically cost more than rooftop systems. The additional materials needed — including reinforced pole structures and cement foundations — are responsible for much of the added expense. Labor charges are also higher for ground-mounted panels, due to the more involved mounting process.
Are solar trackers worth it?
In most cases, solar trackers are not worth the additional investment, even though they do produce more electricity.
