Discuss how to design the solar street light, solar street lamp installation Angle

A lot of people when installing solar street light, not clear how the Angle of the solar panels to determine, whether in that direction. Install solar panels are always facing south, basic consistent with local latitude Angle. Solar panels are generally placed in the lamp cap

when installing solar street lights, many people don't know how to determine the Angle of solar panels, and which is in the right direction. When installation, solar panels are always facing south, Angle and local latitude are basically identical. Solar panels are usually placed at the top of the lamp holder, all of the cable through the tube and extends to the inside the lamp post. ( 1) Slope at noon, in order to let the sun shine on the solar panels, vertical when installing solar panels and the angles between there should be a horizontal plane. Solar panels and the Angle between the horizontal plane is usually referred to as slope Angle, which can be measured. When cant attain to the maximum amount of solar radiation on receiving, known as the best Angle. The diagram below shows the solar panels and the Angle of the relationship between the ground. According to the principle of geometry, in order to make the sun rays vertically on the panels, the panels shall be calculated as follows: the Angle Angle = = 90 degrees; - High Angle ( Elevation) Because the earth runs at a certain Angle, so the sun at noon Angle change periodically every year above the horizon. The above formula shows that the reasonable Angle of the panels should be changes over the height of the sun. ( 2) To determine the square formation dip Angle in order to maximize the ability of solar panels to receive sunlight, the inclination of the panels should be equal to the latitude. When the dip Angle is equal to the latitude, the projection on the solar panels have the highest average sunshine intensity. In addition, in order to consider the periodic change of the Angle of the sun, panel Angle must be tracking the change of the Angle of the sun, it is not only technically difficult and very expensive. There are also some customers in order to beautiful and place the solar street light board level. In this case, the output power of solar panels will be reduced 15% 20%, and add on the solar battery decorative cover, this will make the output power of solar cells is reduced about 5%. This greatly reduced the efficiency of the panel, and affect the use of a complete set of solar street light. Here, we strongly recommend that users do not use in horizontal.
