Solar Panel Angle Latitude

It turns out that you can do better than this about 4 better.

Solar panel angle latitude.

For the best results solar panels should be oriented towards the south. Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and then adding 24 degrees. The summer optimum tilt angle on the other hand will be 34 15 19. The sun s noon angle will vary 23 5 degrees throughout the year being at an angle of 90 latitude at the equinox mar 21 and sept 21 and 23 5 higher than this at the summer solstice jun 21 and 23 5 lower at winter solstice dec 21.

These angles will give you the best overall output over the course of the year if you re going for a fixed installation. This variation is a sinusoidal with the average value being the same as the latitude degrees. This is because the sun is always in the southern half of the sky in the northern hemisphere. To lean toward more production in the winter tilt your panels at your latitude plus 10 15.

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. Whatever your latitude is you can subtract 15 from it to calculate the angle for summer. Both of these angles require latitude degrees.

To lean toward more production in the summer tilt your panels at your latitude minus 10 15. For instance if your latitude. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.

To optimize overall production year round tilt your panels at your latitude. Similarly you can calculate the angle for winter by adding 15. For los angeles a solar panel tilt of 19 degrees works the best. It is simplest to mount your solar panels at a fixed tilt and just leave them there.

While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. There are two methods for calculating the tilt angle for solar panels.
