How to Maintain All In One Solar Street Lights?

All in one solar LED street lights use sunlight as their main energy source, so they can be installed as long as there is sufficient sunlight, and they are also called green products due to their advantages of no pollution. In addition, the all in one solar LED street light is a new energy street light designed with an efficient lighting source, and has the characteristics of high brightness, easy installation, stable and reliable operation, no cable installation, no consumption of conventional energy, and long service life.

How to take good care of solar street lights？

Trim the surrounding trees

The less shady the spot of the solar street light panels is, the more sunlight they will absorb. As a result, more power will be generated. Removing shade-creating objects from the path of the sunlight is a crucial step in taking care of solar street lights.

Keep a keen eye on the shrubs and tree branches that grow around your solar street light and trim them regularly so they don’t hinder the power generation.

Remove dust

The influence of dust is mainly directly can be seen on the solar panels, because the dust will mainly affect the solar panels’ absorption of sunlight radiation, thus affecting the solar panels’ power generation efficiency. Normally, daily regular cleaning is no need because rainwater washes away the dust attached to solar panels on rainy days, but in some particularly arid environments or regions, rainwater is very few. Users can clean the solar panels regularly according to the actual situation, such as once a quarter, or once a year, depending on the rain and dust conditions of the installation site.

Maintain or replace the battery

Usually, do not need to do special maintenance or replace batteries during the service life if they use high-quality & reliable batteries. According to our previous experience, LED light source and solar panel generally do not need to be maintained after the service lifetime, but the performance of the battery may decline after five years, so if the service lifetime exceeds, the lamp is still working, but the number of continuous rainy days has decreased significantly, we can consider replacing the battery for adding another life cycle.

Clean up in the winter rainy season

In some countries, winter snowfalls very long and heavy, or some lamps are installed near tall trees. Snow, leaves and bird droppings may be attached to solar panels. When there is a decrease in power generation efficiency, such as a decrease in the number of continuous rainy days or a shorter light-on time, which reminders they need to be cleaned up.

Check the connections and wires

You should check for any possible damaged wires and broken connections every 3 to 6 months. Following this step will significantly increase the life span of your solar street light. Do a detailed analysis of the wires and if you spot any irregularity or problem in the wires, change them before a little problem shuts down the whole system.

While most of the maintenance tips provided in this blog are quite simple and can be done easily, we would suggest hiring a professional electrician if you have to replace a wire. The solar street lights are very compact and have intricate wiring that will be hard to understand for an inexperienced person. It is also not safe to fix electric wires without expert supervision.

Consider salt corrosion

If the lamp is installed near the seashore or in places of heavy corrosion with high salt fog, the installation bracket should be inspected regularly. We suggest that the installation bracket be inspected once a year, depending on the actual situation of the installation site. Normally, no additional maintenance is required.

Generally speaking, integrated solar street lamps require little maintenance unless they are installed in harsh environments.

How to repair solar LED street light?

However, if the all in one solar LED street light is broken, how to repair it?

First of all, test the core part of the all in one solar street light – solar street light controller. If it cann’t be turned on normally, the red light indicates that it is charging, flashing indicates that the power is full, and the yellow light indicates a loss of power. If the light cannot be turned on normally, it is necessary to check the battery voltage of the solar street light. If it is normal, the solar controller needs to be replaced.

Secondly, if it is not the failure of the solar controller, it is necessary to further inspect whether the solar panel can be charged normally. If it can not be charged, it shows that there is voltage but no current. At this time, it is necessary to check whether the connector of the solar panel is connected and whether the aluminum foil has current. If there is no current, it can be basically determined that the solar panel has been scrapped; if there is current, it should be noted whether there is a cover on the battery board or not which causing it cannot be charged.

Once again, test the all in one solar street light battery. Because the storage battery used by many manufacturers does not have the function of waterproofing, it may also cause the short-circuit of the battery after water penetrating , and cause the voltage to be unstable. Therefore, when testing, be sure to carefully observe the battery voltage changes with the depth of discharge, replaced if not properly.

Finally, detect whether there is damage phenomenon for all in one solar street lights. If its insulation is worn out, the current will also be transmitted through the solar light pole and cause the street light to be short-circuited. In addition, if the all in one solar street light also lights during the day, it may be that the controller components are burned out.

Conclusion

Solar street lights are quite simple to use, but like all other electric appliances, they need to be used with care. Maintaining the solar street lights properly will add to their lifespan and give you your money’s worth. The maintenance is not hard, all you have to do is be aware of the state of the solar light and catch the problem before it affects the electricity production drastically. If you have any questions, please feel free to contact us. We’d love to help you to maintain or replace your all in one solar lights.
