There are many different opinions about the optimal angle in many places, and because there are many differences in different regions, the calculation of the specific angle is relatively complicated, so the angle of solar mounts on the market is generally not very standard, but It does not affect the use of.
The use of solar energy found that this method mainly uses both direct radiation and scattered radiation that are too hot, and the impact of anti-radiation is very small. According to some angle calculation methods, some angles can be calculated, but there are always differences in the specific installation. If accurate calculations are not required, most of them are installed at the approximate angle of a region. And make corrections based on the data obtained in the specific situation.
Generally speaking, many people can view the best daily angle or monthly angle of the local area on the longitude and latitude of the area, and choose the best angle. In normal life, it can also be judged according to some authoritative regional signs.
As for the effect that can be produced by the best angle, detailed calculations are needed.
Sun altitude angle=90°-the difference between the latitude of the place and the direct sun point
