Should you install solar panels on your roof?

As renewable energy becomes increasingly popular, more and more homeowners are considering harnessing the power of the sun by installing solar panels on their roofs. Solar panels power your home with light from the sun and help reduce your electricity bills.

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 much space do you need to install solar panels?

You must allow for a “3-ft clearance down from the ridge of a pitched roof” is an example from the IFC code. In general, when all these codes are applied, we can use about 75% of the total square footage of our roof for installing solar panels. Size of solar panels (or, better yet, watts per square foot of solar panels).
