Installed solar panels typically weigh around 2–4 lb (0.91–1.81 kg) per 1 sq ft (930 cm 2 ), which—if the panels are installed properly so the load is evenly distributed—is typically manageable for a roof in good condition. Consult a structural engineer if you have any concerns about your roof’s capability to support solar panels.
Commercial solar panels weigh around 50 pounds. Frames and mounting equipment for both panels weigh about the same amount. It is also important to consider the weight of installing solar panels on your rooftop. On average, mounting equipment and solar panels weigh two to four pounds per square foot.
In fact, a shingled roof should be able to support 20 pounds per square foot and a clay tile or metal roof should support 27 pounds per square foot. With most solar panels distributing 40-45 pounds of weight across 18 square feet (about 2.5 pounds per square foot), your roof should be able to easily support an entire solar system.
