In this article, you''ll learn how to assess your roof''s dimensions, the factors that influence solar panel placement, and practical tips for maximizing your solar energy potential.
Let''s walk through how to calculate the amount of solar power your roof can generate based on its size, orientation, and angle—as well as the solar panels you install.

By installing solar panels on their roofs, they’re aiding the transition, saving money on their energy bills, capturing more of the sun’s rays, and creating a brighter future. You may wonder, “How many solar panels can I fit on my roof?” After all, maximizing power generation is critical if we ever want to harness all of the sun’s energy.
To calculate how many panels can fit on your roof, divide your open roof space by 20 square feet (or however large your particular solar panels are). For example, if you have 500 square feet of open, available roof space, that's enough space for about 25 solar panels.
You can put a 7.763 kW solar system on a 600 sq ft room. If you use only 100-watt panels, you will be able to fit 77 of them on the roof. If you use only 300-watt panels, you will be able to fit 25 of them on the roof. If you use only 400-watt panels, you will be able to fit 19 of them on the roof.
850 square feet of usable roof space for solar: The average U.S. roof is about 1,700 square feet. You should never put panels on northern roof planes. So with a north/south roof, that gives you 850 square feet. 400-watt solar panels that are 20 square feet in size: This is the most frequently quoted panel power output on EnergySage.
Our solar panel calculator helps you determine how many solar panels can be installed on your roof and how much electricity they can generate. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination, and panel type.
This is a standard 10kW solar system, consisting of 25 400-watt solar panels. As we will see in the summarized chart below, the minimal roof size for a 10kW system is only 800 sq fr roof area (600 sq ft viable for solar panels due to 75% code consideration)
