The weight is within the acceptable limits of any roof.
Solar panel weight per area.
With these numbers in mind, it is important to check whether your roof structure can withstand such weight.
Most structures built after 1970 are designed to support loads far greater than this.
In terms of weight per area, the average weight/area of a residential solar panel is around 2.25 pounds per square foot (24.3lbs/m² or 11kg/m²).
The average size of above 330 watt solar panel is 2 meter x 1 meter ( 6.5 ft x 3.25 ft ) and weight is approximately 25 kg.
On average, photovoltaic panels weigh around 40 pounds per panel.
These modules also weigh 52.9 pounds.
Photovoltaic solar panel with 72 cells.
The surface area of a 330 watt solar panel is 21 sq.ft and the maximum weight exerted by solar panels on your roof is 1.8 kg.
How large are solar panels on average?
With regards to their dimensions, the solar panel surface area is 2.22 square meters or 23.87 square feet on average.
So a solar panel of this size and weight distributes about 2.4 pounds over each square foot it covers.
The weight of a solar panel per unit is an important consideration when deciding which size is best for your home, which we will discuss further in a later section.
Go for a structural analysis before making any move with the panels.
Solar panel weight on your roof.
1000 watts = total area x 1000 watts/m 2 x 0.18.
The total area covered would be around 352 square feet.
I you are going to install all the panels in one line you would need a space of approximately 1 m x 5.56 m (each panel having a size of 1 m x.
You can expect a photovoltaic solar panel to weigh anywhere between 33 to 50 pounds.
