Technical FAQs 4

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 watts can a solar panel produce?

For example: A 100-watt panel can produce 100 watts per hour in direct sunlight. A 400-watt panel can generate 400 watts per hour under the same conditions. This doesn’t mean they’ll produce that amount all day, output varies with weather, shade, and panel orientation.

How many 400 watt solar panels on a 1000 sq ft roof?

A typical 400-watt solar panel is 79.1 inches long and 39.1 inches wide, taking up 21.53 sq ft of area. If you have a 1000 sq ft roof and you can use 75% of that roof area for solar panels, you can theoretically put 34 400-watt solar panels on a 1000 sq ft roof.

How much power does a solar panel produce a day?

Most residential solar panels have a power output of around 250-400 watts, and can produce up to 2.5 kilowatt-hours of electricity per day. Why don’t those numbers add up? Because a solar panel only produces energy when the sun is out, so we can’t multiply 400 by 24 to determine its daily output.
