Technical FAQs 4

How much solar power can a 2000 sq ft roof generate?

Let’s take a big 2000 sq ft roof as an example. Such a big roof has 1500 sq ft of viable solar panel area. If each of these viable square feet generates 17.25 watts of electricity, the combined 1500 sq ft will be able to generate more than 25kW per peak sun hour (25.875kW, to be exact).

How many watts can a solar system put on an 800 sq ft roof?

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.

How many solar panels can you put on a 600 sq ft roof?

You want to put solar panels on (due to 75% available area, the viable roof area is 450 sq ft, the calculator accounts for that). Just slider the slider to ‘600’ and you get the results: You can put a 7.763 kW solar system on a 600 sq ft room. If you use only 100-watt panels, you will be able to fit 77 of them on the roof.

What is the minimum roof size for a 10kW Solar System?

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)
