How to Find the Best Angle for Your Solar Panel

Use the map below to find what your latitude is. When you've located your city using the zoom controls, click on it to find what your latitude is. This will be the best angle for your solar panels to be at.

The best angle for your solar panels to be at is the angle of your latitude.

If your latitude was a negative value, you want to face your solar panels North.

If your latitude is a positive value, orientate your panels South.

You can in fact be 15 degrees to either side of this optimum setting without losing much power or efficiency from your panels.

You can also set your solar panel for optimum performance in summer and winter. In summertime, the solar panel should be at a lower angle.

This is because the sun is higher over head. In wintertime, the sun comes moves across the sky at a lower angle. So by angling your solar panels higher, you will catch more sun rays.

For the Northern hemisphere, your panels should be facing as close to South as possible.

In the Southern hemisphere, you want to orientate your solar panels to the North.

There are tracking devices that follow the sun throughout the day, winter or summer. While these will gather more sunlight, the added expense of the tracking device may not justify the savings from gathering more sun energy.

A simple ratchet system can also be used on the solar panel angle mount to shift position twice a year from winter to summer settings.

For example, if you are living at 12 degrees North of the Equator, you want to face your panel directly South at a 12 degree angle.
