A solar roof or rooftop photovoltaic (PV) system is a setup where electricity-generating solar panels are mounted on the roof, utilizing the prime exposure of the rooftop to sunlight and creating one of the most environmentally friendly roofs possible.
As of 2026, the average cost to install solar shingles is $21 to $25 per square foot, or $2,100 to $2,500 per roofing square (100 square feet), including installation and labor.
Rooftop solar for factories refers to solar panels installed on the roofs of manufacturing facilities to generate electricity. These systems convert sunlight into electricity that powers factory operations, helping industries reduce electricity costs and dependence on grid power.
