Solar Panel Angle to Horizontal

I have done a brief search and canít find a good source of optimum installation for solar panels relative to angle of panel to horizontal. I will be mounting a small panel on a post and can choose exactly the angle I want. Will not be able to change it for different seasons so want a good compromise for winter to summer sun angles.

I live in San Diego, CA which is similar to Ft. Worth, TX or Savannah, GA.

Anyone know where to find such info. or suggest the optimum angle?

Hi there,

there are several items to balance, including location, seasons, roofs'sahdows, etc

There are several computer programs (most of them free) that are great to develop simulations
You will find a lot of info regarding this type of software in this page of the U.S.D.E.

Collector angle

Compromise between summer and winter sun is the same as the latitude of your location. The farther north you are, the more vertical it'll face south.
