On average, solar panels weigh between 10 and 20 pounds per square meter. For a sound roof, this weight won't threaten the roof's stability under the panels. The weight doesn't spread evenly across the surface of your solar panel. The fixtures where the panels are mounted bear the bulk of the weight for each panel.
Generally, standard residential photovoltaic panels weigh between 40 and 50 pounds (about 18 to 22 kilograms). This weight makes them manageable, but still requires careful lifting during installation. Why is knowing the photovoltaic panels weight so important before installation?
This statistic may be more meaningful for you in figuring out if your roof can bear the weight of solar panels. For residential photovoltaic panels, the typical weight distribution is four pounds per sq foot, quite manageable for most residential roofs. While more common in commercial settings, some residences do have them.
When you take into account the solar panels and all the mounting equipment, racking, junction boxes, and wiring, the total weight of the solar installation comes in at around 3-4 pounds per square foot (this does not include the inverter, which usually gets bolted to the wall).
