For a 10KW system, roof space needed is in the range of 800 – 1200 sq ft
- 71.5 sq meter (770 sq ft) area needed for 14% efficiency panels for elevated structure
- 50 sq meter (550 sq ft) of area needed for 20% efficiency panels for elevated structure
- For low profile systems, typical area is 1.5X to 2X higher to allow for spacing between rows of panels to avoid shading
