Solar Panel Inclination Angle

Orientation of the panels 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.

Solar panel inclination angle.

For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. To get the best out of your photovoltaic panels you need to angle them towards the sun. Tilt the panels to your latitude minus 15. Here two simple methods for calculating approximate solar panel angle according to your latitude.

The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month basis. This is because the sun is always in the southern half of the sky in the northern hemisphere. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. If you are able to adjust the angle of your solar panels a few times per year here is the adjustment schedule we recommend.

Tilt the panels to your latitude plus 15. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. These angles will give you the best overall output over the course of the year if you re going for a fixed installation. For the best results solar panels should be oriented towards the south.

Tilt the panels to your latitude. For los angeles a solar panel tilt of 19 degrees works the best. 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.
