How much solar power can a roof generate?

The amount of solar power your roof can generate depends on various factors, such as your location, roof size and orientation, solar panel efficiency, shading, climate, and the size of the solar system. But our experts can help you find a solution to meet your energy needs.

How many solar panels can fit on a roof?

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.

How many watts do solar panels produce per square foot?

The smarter way to use the data about how many watts do solar panels produce per square foot. In fact, by averaging different wattages and dimensions of solar panels, we can see that an average solar panel will produce 17.25 watts per sq ft of roof area.

How many watts can a solar system put on an 800 sq ft roof?

Let’s use the above equation to calculate this: Max. Solar System Size (800 Sq Ft) = 800 Sq Ft × 0.75 × 17.25 Watts / Sq Ft = 10,350 Watt = 10.35kW Solar System Now, by average solar panel wattage per square foot, we can put a 10.35kW solar system on an 800 sq ft roof.
