For instance if the surface area is 1 500 square meters and the rating of the panel is 250 watts you would divide 250 by 1 500 and then multiply by 100 to find the percentage for this example the solar panel in question would have an efficiency rating of 16 67 250 1500 x 100 16 67. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.
