Angle of roof solar panels

What angle should solar panels be mounted?

Another factor to consider is your home's roof slope. The average American home ranges in pitch from 4/12 (18 degrees) to 9/12 (37 degrees) 6. To find the optimal angle to mount your solar panels, take your base tilt from your latitude and subtract it from your slope. Let's take a look at some examples:

What is a solar panel tilt angle?

Tilt angle is defined as the number of degrees your array orients from the ground so it can face the sun. An easy method for determining solar panel tilt is to match the latitude of your home. This can vary depending on your north-south location, but it generally ranges from 30-45 degrees for homeowners in the continental United States.

What is the best solar panel angle?

As we've mentioned earlier, your location's latitude plays a major part in determining the best solar panel angle. Across the continental U.S., the optimal tilt can range from 30-45 degrees. However, the further north you live, the more orientation can affect solar panel efficiency.

How do I determine the optimal solar panel angle?

A more precise method for determining optimal solar panel angle is to use your location's latitude as a starting point. The rule of thumb is to set your panels at an angle equal to your latitude for optimal year-round energy production.
