Do You Know The Best Angle To Place Solar Panels?

Solar panels are charged by solar energy, so how do they have to be installed to get the maximum charging effect? In fact, we just need to set the angle of the solar panel. So how to set the solar cell installation angle is more reasonable?

Does the tilt angle really matter?

 

Yes. The tilt of solar panels affects the power they produce because the tilt affects the amount of sunlight you capture. Consider a solar panel that is flat on the ground and 1 meter wide. When the sun is in the middle of the sky (e.g. in the middle of the day in summer), that solar panel will fully capture a 1-meter wide axis of sunlight. If the sun is at an angle of 30° to the horizontal, that same 1-meter-wide shaft of light will actually spread over 2 meters as it hits the ground. A planar solar panel will capture only half of the sunlight, thus producing half the energy compared to the sun directly overhead.

 

Why was the angle of the solar panel chosen for the local latitude?

 

Because your latitude is the same as the angle of the sun in the sky between mid-winter and mid-summer. The sun is about 15 degrees higher in the sky in summer and about 15 degrees lower in the sky in winter. Therefore, tilting your panels to the midpoint will maximize the amount of sun captured throughout the year.

 

The best orientation angle for solar panels

Generally speaking, the direction due south is the direction with the highest intensity of sunlight. The installation should be within a 20-degree angle due south and will not have any major impact on power generation. The only thing we have to pay attention to is that the solar street light is installed in the strongest possible lighting, trees, houses may affect the solar panel lighting time, thus affecting the charging. Of course, solar street light panel installation angle should be as far southwest as possible within 20 °, so that the peak of solar power generation in the noon slightly after a certain time, so that favorable winter degree more power generation. When the south direction solar panel laying area is not large enough, solar panels can also be laid in the east, west direction.
