A rule of thumb for optimizing the angle of your solar panels is to mount them at an angle equivalent to the site’s latitude, facing due south. The latitude of Normal, Illinois, is 40.5°.

For most homeowners, the ideal angle for a solar panel installation is close to or equal to the latitude of your home. This angle is typically between 30 degrees and 45 degrees.

The optimal tilt angle of solar panels is critical for maximising energy capture while ensuring efficient integration into diverse climates and geographic conditions. Recent research has focused ...

They also found that a 10-degree tilt angle also increased power generation by 5.9 %, 6 %, 4.1 %, and 2.4 % in Chandigarh, Bhadla, Kolkata, and Kurnool, respectively, compared to the latitude tilt ...
