For PV systems, power generation is undoubtedly the most critical factor, as it directly impacts the return on investment. The installation angle of solar mounts is one of the key factors influencing power output, and how to determining the optimal angle to maximize annual solar radiation is a topic worthy of discussion.

The installation angle not only affects power generation efficiency but is also closely related to the stability and cost of the whole PV system. An inappropriate angle will reduce power generation efficiency and impacting investment returns: an excessively large angle increases the structural strength requirements of the support structure, and then raising costs; an excessively small angle may reduce support costs but could require more land area for solar module installation. Therefore, it is necessary to comprehensively balance factors such as power generation efficiency, stability, and cost to determine the optimal installation angle.

The installation angle of solar brackets includes two angles: tilt angle (the angle between the PV module and the horizontal ground) and azimuth angle (the angle between the orientation of the PV module and due south). Both changes in tilt angle and azimuth angle will affect the power generation of power station.

Geographic location is a key reference factor, and generally speaking, solar panels need to face towards the equator to fully utilize solar energy resources. Latitude also affects the optimal installation angle of solar panels. In low latitude regions, solar panels can maintain a relatively flat angle; In high latitude regions, solar panels need to be tilted appropriately to better utilize sunlight. Here are some quick empirical formulas to preliminary determine the angle:

Optimal inclination angle ≈ local latitude ± 5 °

-Low latitude (<30 °): latitude - 2 ° to 5 °

-Mid latitude (30 ° -40 °): latitude ± 2 ° (seasonal equilibrium)

-High latitude (>40 °): latitude+2 °~5 ° (large angle is beneficial for snow removal)

-Minimalist estimation: latitude x 0.9

To accurately determine the installation angle, you need to seek the help of a professional engineering team who will use specific software for simulation calculations.
