Fixed Solar Panel Tilt Angle

Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.

Fixed solar panel tilt angle.

Azimuth angle is their horizontal facing in relation to the equator. Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter. There are two methods for calculating the tilt angle for solar panels. In this way at noon the panels will be perfectly perpendicular to the sun s rays.

If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. For fall or spring you can just subtract 2 5 from the latitude. On the picture below is a easy to understand map. Solar panels with a fixed tilt angle.

If your latitude is outside this range see other situationsbelow. This table gives some examples. Solar panels should face directly into the sun to optimize their output. An additional 3 5 though can be gained by evaluating this more carefully.

The angle is based on your latitude minus 15 degrees. The tilt angle or elevation angle describes the vertical angle of your solar panels. In boston a solar array at 30 degrees south is still going to produce more electricity than tilted at 42 degrees and facing north. A solar panel tilt of 19 degrees will work best in los angeles.

Solar panels should always face true south in the northern hemisphere north in the southern hemisphere tilted from the hoizontal at a degree equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. For a precise method use the second formula on this page to calculate tilt angle. There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels. Calculating minimum sun height at noon.

The best tilt angle for winter is the latitude times 0 875 plus 19 2 degrees. Showing with clear colored lines what your best solar panel angle will be depending on where on earth you live. Both of these angles require latitude degrees. Similarly you can calculate the angle for winter by adding 15.

For panels that you will want to use all year and not have to touch once they are installed you will want to install at a solar panel angle optimized for just that.
