Solar is a renewable energy technology that can be easily integrated into existing infrastructure. A photovoltaic solar system, which silently produces clean energy without any moving parts, is ideal for on-site applications at commercial facilities. Depending on the quantity and kind of available space, there are different types of installations that work best. Most on-site commercial solar installations fit into three broad categories: roof-mounted, ground-mounted and parking canopy systems. Below, we describe the different categories and the advantages of each.
