The sun rises in the east and sets in the west. However, the sun moves all day long, but initially rises from the east and eventually sets in the west. Understanding the trajectory of the sun is essential if you want to understand the optimal tilt angle and direction of solar panels.

The direction of the solar panel simply refers to which direction the solar panel faces: north, south, east, or west. For houses located north of the equator, the correct orientation for solar panels is due south. For houses located south of the equator, the opposite will be true, with solar panels facing north. In summary, the orientation of the solar panel should be opposite to the equatorial direction of the house.

The solar panel angle is the vertical inclination of the solar panel. It can be a bit tricky to understand, as the appropriate inclination can vary depending on geographic location and time of year. Geographically, the angle of the solar panel increases as it moves from the equator. For example, in states such as New York and Michigan, the sun’s position in the sky is much lower, which means that solar panels require greater inclination.

To find the best angle for solar panels, you first need to understand the local latitude (I don’t know, you can search in Baidu). Generally, the ideal angle for solar panels will be equal to or close to the local latitude. However, the appropriate solar panel angle can fluctuate throughout the year, with the latitude added to 15 ° for summer and warmer months. For winter and cooler months, the ideal solar panel angle will increase by 15 ° at the latitude of the region.

The suitable angle of solar panels is not only affected by geographical location, but also by the seasonal changes in the sun. During the summer months, the sun moves higher in the sky. In winter, the sun moves lower in the sky. This means that in order to obtain the maximum output from solar panels, it is necessary to appropriately change the inclination every season.
