Optimal installation direction of solar panels
When the sun’s rays are maximized to the solar panel, the solar panel can achieve high efficiency in generating electricity. This dictates that the best direction to install solar panels should be towards the direction where the sun is most compact, i.e. due south. However, this is not a certainty, if your solar panel is facing south, it will cause inconvenience to you, and don’t worry, your solar panel can still generate electricity, only the efficiency of electricity generation will be reduced. Depending on the situation, the best direction to install solar panels can vary. In the northern hemisphere, the best direction for solar panels should be towards the south, while in the southern hemisphere, the solar panels should be facing north, they can both maximize the reception of sunlight to generate more electricity.
The best installation angle for solar panels
The angle of the solar panel will affect the efficiency of solar power generation. If the angle is too large or too small, the power output will be reduced. Generally speaking, the mounting angle of solar panel should be kept between about 20° and 40°, but the optimal angle of solar panel also varies according to the latitude and longitude where it is located, if you require more details, we will introduce it below.
How to adjust the optimal direction and angle of solar panels?
1. Use solar tracker: solar tracker mainly according to the sun’s light intensity changes in real time, through the automatic tracking mode and fixed tracking mode switching, to ensure that the solar panels can be real-time directly to the sun, so as to improve the utilization rate of solar energy. However, solar trackers are expensive, so be practical and consider carefully whether to use them.
2. Manual Orientation Adjustment: Solar panels are usually installed with fixed angle brackets, but in the course of daily use, the orientation of the solar panels can be adjusted manually to improve the efficiency of solar energy acceptance. However, this requires the solar panel to be installed in a more open area for easy adjustment. It also requires several adjustments depending on the actual situation to find the optimal orientation.
3. Globalsolaratlas, this tool will calculate the specific tilt angle and azimuth angle of the solar panel based on the latitude of the specific area, which makes the process of using it very convenient.
FAQ
In order for solar panels to maximize the amount of power they can generate, if the orientation and angle of the solar panels are not good enough, obstacles such as trees in the vicinity can have an impact on the lifespan and energy production efficiency. The optimal orientation and angle allows you to maximize energy production, thus helping to protect the environment and reduce energy costs.
Tilting solar panels avoids the reflection and scattering of solar radiation, improving the reception of sunlight. And it reduces the amount of time the panels are exposed to the natural environment, extending the life of the modules.
While south-facing solar panels result in maximum efficiency, some areas, such as the Midwest, may be best oriented for solar panels facing southwest.
Basically, no. There are traditional riveting methods for securing solar panels on the roof, racking methods, and frameless sliding solar panels. The staff will choose the suitable fixing method according to different roof angles to match the best installation angle, independent of the roof angle.
