How To Determine The Installation Direction And Angle Of Solar Panels?

The orientation and angle of installing solar panels. Take into account the full use of solar energy. According to physics, the longer the sun shines on a solar panel and the closer it is to vertical exposure, the more energy it receives.

The orientation and tilt angle can be divided into two parts:

Direction:

I want to receive the most sunlight throughout the day. The principle shows that the solar panel faces.

The southern hemisphere faces north, and the northern hemisphere faces south.

Slope:

The tilt angle of the panel is to allow the sun to receive as much energy as possible, and the size of the tilt angle is related to your latitude. Next, let's take a closer look. Because the Earth's axis of rotation and orbit are not perpendicular. In our opinion, the sun angle is different in different seasons, with a difference of ±23.4 degrees. The median value of the sun angle occurs on the vernal and autumnal equinoxes. At noon that day, the angle of the sun is exactly equal to (90 degrees - your latitude). Through comprehensive calculation, the optimal tilt angle for a year should be a little larger than your latitude to reach the maximum value received throughout the year.

Installation area:

Average: 1KW solar panel requires about 10 square meters of the installation area.
