Typically, solar panels perform best on south-facing roofs with a slope between 15 and 40 degrees, though other roofs may be suitable too.. Typically, solar panels perform best on unshaded, south-facing roofs with a slope between 15 and 40 degrees.. Each roof plane with a PV array on it must have a 36-in. or wider pathway on that roof plane, an adjacent roof plane, or straddling that plane and an adjacent one—for example, a valley or hip.. We use the following assumptions to calculate solar generation potential:A roof size of 850 square feet (half the size of the U.S. average, as people with north/south roofs should only put panels on the southern side)400-watt solar panels (the most frequently quoted panel size on EnergySage) that are 17.5 square feet in sizeU.S. average 5 hours of direct sunlight (known as sun-hours) per day [pdf]

Should I add a solar energy system to my roof?

You may be considering the option of adding a solar energy system to your home’s roof or finding another way to harness the sun’s energy. While there’s no one-size-fits-all solar solution, here are some resources that can help you figure out what’s best for you. Consider these questions before you go solar. See the Spanish version here.

How do I determine my home's solar rooftop potential?

Determine your home’s solar potential. Aside from your roof’s condition, your home’s solar rooftop potential depends on your geographic location, the position of your home in relation to the sun, how much shade you have, and the PV system you and your installer choose.

How much solar power does a roof generate?

In a perfect world, the average roof in the U.S. can generate around 35,000 kilowatt-hours (kWh) of solar electricity annually—far more than the average home’s annual electricity usage of 10,600 kWh. Realistically, your roof’s solar generation potential will be less than that.
