As we ve mentioned there is no one best angle for all regions in the usa.
Best angle for solar panels latitude.
There are two methods for calculating the tilt angle for solar panels.
For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
Subtract 15 degrees from the latitude at your location during summer and add 15 degrees to your latitude during winter.
Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and.
The following table gives the best dates on which to adjust.
Similarly you can calculate the angle for winter by adding 15.
Ultimately what s the best angle for solar panels in the usa.
Both of these angles require latitude degrees.
For a precise method use the second formula on this page to calculate tilt angle.
To find your latitude consult a map for your region.
To lean toward more production in the winter tilt your panels at your latitude plus 10 15.
It s not a good idea to install your panels to face a suboptimal direction even if it means the best tilt possible.
For a latitude up to 25 take your latitude and multiply it by 0 87 for a latitude between 25 to 50 take your latitude multiply by 0 87 after that you will add 3 1 degrees for a latitude over 50 the most ideal angle will end up being approximately 45 degrees.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you.
The more exact way to count out the best tilt angle is done as follows.
The summer optimum tilt angle on the other hand will be 34 15 19.
To lean toward more production in the summer tilt your panels at your latitude minus 10 15.
There s a simple rule of thumb for calculating the best tilt angle for fixed mount solar panels.
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.
In boston a solar array at 30 degrees south is still going to produce more electricity than tilted at 42 degrees and facing north.
