1. What to do if the 20W solar street light doesn't work

What should we do if the solar street light doesn't work? This is undoubtedly the most important question that customers want to ask. If this problem occurs, the first thing we need to do is to check whether the battery indicator light is on. If it is not on, it may be that the connecting wire between the controller and the battery is off. At this time, we need to ask professional people to connect. If the wiring is normal, then we need to check whether the battery voltage is normal. If not, then we need to make the controller worse.

2. Do photovoltaic modules of 20W solar street lights face south

As we all know, solar street light absorbs sunlight and converts it into electric energy, which is stored in the battery. At night, the battery discharges the light head, so that the solar street light lights up. The orientation of the photovoltaic module determines how much sunlight the solar panel can absorb and how much electricity it can convert into. If the direction is not right, there will be less sunlight absorbed, so the light may not be on for a long time or not at all.

The photovoltaic cells of solar street lights generally face south, so that the photovoltaic modules can absorb more and more average light radiation. But don't worry too much, because most manufacturers design the best tilt angle for solar panels according to the sunshine conditions in the region.

3. Is the battery board of solar street light fragile

The solar panel is very solid, generally composed of quite solid toughened glass panels. Regular manufacturers will test the solar panel through hail, so there will be no problem with the solar street light panel, even if it is rainstorm or hail, it has a certain resistance.

4. Can 20W solar street lights be installed in shaded areas

The solar panel must absorb enough sunlight to be able to convert into electric energy. If the solar panel is installed in a shaded place, it will absorb less sunlight, and the output of the battery will be relatively small. Generally, the installation of the solar street light should not be in the shade but should avoid the shelter, because it is not afraid of wind and sun, and can absorb the sun all day, which is good for the operation of solar street light.

5. Does the cleaning board of 20W solar street light need to be cleaned frequently

The solar street light's battery panel can't accumulate dust for a long time, because it's not conducive to solar panel absorbing sunlight. If the battery board has a shady surface, the string of batteries may cause an open circuit. But in general, the solar street light's battery panel does not need to be cleaned frequently, because when it rains, the dust on the solar street light's battery panel will be washed away. If it doesn't rain for a long time, clean the solar panels occasionally.
