To maximize endurance and efficiency, solar panels must be mounted onto a solid structure and face east, west or south and have little to no shade from trees or other buildings.
The most common method of installation is to mount the panels to the roof with a standard slope. Solar panels can be mounted on a flat roof however the installation requires additional expertise that may add a little to the cost. The solar panels can be mounted to a pole if tree cover is an issue, but the ideal situation is to mount them to the sunny side of your roof or if you have some available open space, ground mounted systems are common and affordable as well.
