If you’re doing research on powering a home or business with solar, you might be wondering, “How large is a solar panel?” This article will answer that question along with dimensions, weight, and more popular topics about going solar.

How big are solar panels?

The standard sized panel used on a residential solar project is 65 inches by 39 inches or a little bigger than 5 feet by 3 feet (17.55 square feet). The exact size varies by manufacturer, but this is a common or safe measurement to use in your calculations of how many solar panels will fit on your roof.

SolarWorld – 40 to 47 lbs

Other common questions about going solar

Can my roof support the added weight of solar panels?

The roofs on most newer homes can handle significantly more than the average 3 pounds per square foot of weight from a solar panel installation. However, if you have an older roof or are concerned about whether your roof can support the additional weight of a solar power system, talk to a roofing company. A roof inspection can help you determine whether the additional weight of solar panels are a viable option for your home.
