The size of a rooftop solar system refers to the total power-generating capacity of all the solar panels, measured in kilowatts (kW). The system size depends on the number of solar panels and the rated capacity of the panels. System size is measured in kilowatts (kW). One kilowatt (1 kW) = 1000 Watts.
Get an estimate of a suitable rooftop solar system size for your home or business needs. SunSPOT is a not-for-profit solar calculator built specifically to help householders and small businesses with reliable, free estimates.
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)
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.
If you are in an area with less hours of sunshine, you may need a bigger rooftop solar system to meet your needs. Very hot temperatures can also lower the generation of solar systems marginally, but the impact is less important than the amount of sunshine falling on the panels.
The amount of available sunny roof area can often be a limiting factor when deciding what system size to install, particularly for household solar systems in urban areas. One residential solar panel is often around 1.7 m 2 in area. A common 6.6 kW system might take up 29 – 32 m 2 of roof space, depending upon the rated capacity of the panels.
