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.
Number Of Solar Panel By Roof Size Chart. We have calculated how many of either 100-watt, 300-watt, or 400-watt solar panels you can put on roofs ranging from very little 300 sq ft roof to huge 5,000 sq ft roof, and summarized the results in a neat chart. This is a standard 10kW solar system, consisting of 25 400-watt solar panels.
Solar panel power ratings range from 250W to 450W. Based on solar.com sales data, 400W is the most popular power rating and provides a great balance of output and Price Per Watt (PPW). If you have limited roof space, you may consider a higher power rating to use fewer panels. If you want to spend less per panel, you may consider a lower wattage.
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.
