Solar Panel Weight Per M2

On average a solar panel weighs about 40 pounds but it could be as light as 33 pounds and as heavy as up to 50 pounds.

Solar panel weight per m2.

Weight is an important criterion in solar panels as a solar rooftop plant with several panels could exert significant load on the roof. In the case of a 6kw solar installation which constitutes 20 solar panels you are talking about 800 pounds 20 panels by 40 pounds heavy. Based on our calculation above we know that this same system measures at 352 square feet which works out to a weight of 2 3 pounds per square foot 800 pounds 352 sq ft. This depends on the manufacturers and technology used.

In a 6 kilowatt solar installation made up of 20 solar panels the panels alone will weigh approximately 800 pounds 20 panels x 40 lbs. The weight is within the acceptable limits of any roof. The point loads are other considerations to take into account since installers often want to minimize the number of mounting locations for them to. However one has to take into account the point loads as installers often want to minimize the number of mounting locations in order to minimize the risk of leaks.

By dividing the weight of the modules and underlying racking by the area of the modules we generally find that the combined weight of solar modules and the racking that supports them puts about 3 4 pounds of weight per square foot on a roof. On average solar panels and the mounting equipment weigh 2 4 lbs per square foot 10 20 kg per square meter which is usually within the acceptable limits of your roof.
