1.There are too many obstructions in the solar light street lamp installation place, which causes the solar panel charging efficiency decreased.For example, leaves, buildings and other coverings block light, which affects the absorption and utilization of light energy.
2.There is another light source next to the solar panel, which causes the solar panel charging voltage to be above the light control voltage point,then solar light street lamp cannot be lit.For example, there are other street lights next to this solar light street lamp. When the night falls, the street light is lit up, causing the solar light street lamp controller get the current from solar panel ,so it detect it is daytime now, so the controller controls it and does not let solar light street lamp light.
3.Solar panels installed under the wires, branches, poles or other obstructions,resulting in a shadow on the solar panels during the day,then the solar panel will not generate electricity. 4.Installed on both sides of the road, the solar panels are tilted face to face.For the sake of aesthetics, the installer may install the solar panels diagonally symmetrically to face, but if one side is correct, the other side is definitely wrong. On the wrong side, the charging efficiency is reduced because there is no way to direct the light to the solar panel.
5, solar panel angle adjustment has problems, then solar panel charging will be in low efficiency.The correct angle adjustment of the solar panel follows a simple principle: direct sunlight to the solar panel, so that the charging efficiency is the largest.In different places, the angle of the solar panel tilt can refer to the local latitude, what is the latitude, and how much the solar panel is tilted horizontally, so the angle of the solar panel can be adjusted for different latitudes and different pavements.
6.The solar panels are charged indoors.Some customers will install solar light street lamp in the parking shed to facilitate parking at night, but at the same time, the solar panels are installed in the shed, so the charging effect is naturally greatly reduced. In this case, we can use outdoor charging, indoor discharge, solar panel and lamp are separated for installation.
7.Arbitrarily extend the solar panel connection line.In some places, because the installation conditioner is not good,so solar panel have too much interference.The solar panel and the lamp are separated by a long distance.Some customers have a distance of 10 meters or more, and then casually a matter of connecting the two core wires on the market. Since the general wire quality in the market itself is not very good, and the distance of the wire is long,the wire loss is large, so the charging efficiency will be greatly reduced, and the solar light street lamp lighting time will be affected.
8.The on-site personnel will not use the engineering solar light street lamp remote control correctly, and the parameter setting error will not light up.According to many on-site understandings, some construction workers feedback, do not know the functional use of this solar light street lamp remote control, in short, a random press, no matter what lights up. In fact, at this time, it is possible that the parameter has been set incorrectly, causing the lighting to be abnormal.
