1.What is tilt angle

The tilt angle is the angle between the plane of the solar cell square and the horizontal ground. The tilt angle of the PV should be the best tilt angle when the generation capacity of the square is the maximum in a year. The best tilt angle is related to the local geographical latitude, when the latitude is high, the corresponding tilt angle is also large, and vice versa is small, but the original tilt angle of the roof and the tilt angle required for snow sliding should also be considered in the PV installation design.


2.The relationship between the tilt angle of solar panels and the amount of daily radiation and power generation

When the panels faces due south (azimuthal angle of 0° degrees), the tilt angle from horizontal (tilt angle of 0° degrees) gradually raised to the best tilt angle, the amount of its daylight increasing until the maximum, and then increase the tilt angle of its daylight decreasing;

When the azimuth angle is not equal to 0° degrees, the value of oblique daylight volume is generally low, and the value of the maximum daylight volume is near the tilt angle close to the horizontal.

The greater the latitude, the greater the effect of inclination on power generation.


3.How should the tilt angle of solar panels be selected?

We all want to make the most of solar generator. In addition to precise calculation by computer, the following data can be referred to set the tilting angle.

Latitude is 0 ° - 25 °, the tilt angle is approximately equal to latitude, a small angle loss power station power generation less.


Latitude is 26 ° - 40 °, tilt angle equal to latitude can be added to about 5 ° - 10 °, close to the latitude installation angle loss power plant power generation less.


Latitude is 41 ° - 55 °, the tilt angle equal to latitude can be added about 10 ° - 15 °, slightly larger than the latitude of the installation angle loss power plant power generation less.


When the latitude is 55 ° or more, the tilt angle equal to the latitude can be added 15 ° - 20 ° or so, as close as possible to the required angle loss power plant power generation less.
