Technical FAQs 4

How much do solar panels weigh?

If you’re planning a rooftop mounted solar system, it’s critical that you understand how much your solar panels weigh, so that you can determine if your roof can support the system. As with the size, the weight of a solar panel can vary by manufacturer. Typically, 60-cell residential solar panels weigh around 40 pounds a piece.

What are the dimensions of standard solar panels?

Most solar panels are about 1.5 inches thick. The typical classification of solar panel sizes is based on the solar cell size, but it's not very useful for most calculations.

How much weight can a solar panel support?

Solar panel weight is a critical factor for roof structural integrity: Most residential roofs can support 20 pounds per square foot, making solar panels well within safe limits. However, older homes or those with structural concerns should have a professional assessment. Panel thickness typically ranges from 1.4 to 2.0 inches, affecting:

How much does a solar installation weigh?

All things considered, the easiest way to estimate a solar installation’s weight is by first calculating its approximate square footage. In the table below, we assume a total installation weight of 3 lbs per square foot across various system sizes, each using 400 W solar panels.
