The more exact way to count out the best tilt angle is done as follows.
Best average angle for solar panels in mid arizona.
Latitude x 0 9 23 5 degrees.
Latitude x 0 9 29 degrees.
At 90 from true south therefore east and west production can drop to 30.
Once you have figured this out you can use one of the formulas below to calculate the best angle for your solar panels for each season.
This is because it s based on the average position of the sun over your property.
Depending on where you live the best angle at which you should install solar panels will change.
The solar radiation that the panels receive is almost the same.
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.
Latitude 2 5 degrees.
The angle of your solar array is an important factor in maximizing your energy production.
However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly.
Solar panel angle by zip code.
Most solar arrays are installed at a tilt.
For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees.
Most roofs have an inclination of 30 to 40 degrees.
You will most likely be installing the solar panels on your roof which is why you have to take into account the roof pitch too.
The answers you end up with are the best angles for each particular season.
