Best Inclination Angle For Fixed Solar Panel Latitude

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. At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity.
