How to Maintain Your Solar Street Light

A solar street light is an outdoor light fixture that harnesses the radiant energy from the sun to drive its light engine. Nowadays, solar street lights have been widely installed in urban roads, living districts, factories, tourist attractions and parking lots. More and more people benefit from solar street lights.
As is known to all, outdoor lighting systems require a bit of cleaning and maintenance to ensure proper function and illumination and to avoid potentially costly repairs. Since there are no moving parts to a commercial solar street light or solar power system, maintenance is quite easy and doesn’t need to be performed often.
Well, read the following details and find out the basics of solar street light maintenance.
How to Maintain Your Solar Street Light

Clean The Solar Panels

The influence of dust is mainly directly can be seen on the solar panels, because the dust will affect the solar panels’ absorption of sunlight radiation, thus affecting the solar panels’ power generation efficiency. Users are supposed to 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. Regular cleaning will make sure the solar panels function effectively.

Here are some tips for cleaning your solar panels:

(1)Hose off the solar panels to wet them down and wash off any loose dirt and dust.
(2)Then use your brush and soapy water to scrub down the panels. Try to get off the spots by gently using your finger or allowing the soap to soak for a few minutes.
(3)Rinse the panels off thoroughly and make sure that there is no soapy residue.
(4)Take your squeegee to clean up all water on the panels.

Clean The Light Globe

Sometimes, it is the light globe that needs to be cleaned. Because they are exposed to the outdoor environment in a long term, dust and debris do cover the outer covering of the globe. When you take your soft cloth, soapy water and scrub brush out, you can also clean up the mud, dirt or debris from the globes. Do this cleaning can help extend your solar street light’s lifespan and maintain its visual appeal.

Regularly Trim The Surrounding Shrubs And Trees

The less shady the spot of the solar street light panels is, the more sunlight they will absorb. That is to say, more solar power will be generated. Therefore, it is important to remove those shade-creating objects from the path of the sunlight. This task will need to be completed regularly because your solar street lights mainly rely on the sunlight. According to the growth rate of surrounding shrubs and trees, you should prune them as often as once per month.

Maintain or Replace The Battery

According to our experience, LED light source and solar panels 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, we can consider replacing the battery for adding another life cycle.
Solar street light batteries generally last between one and three years before they need to be replaced. You will know your batteries need to be replaced when your lights consistently stay on shorter periods of time at night, when the light becomes dimmed or when your solar lights stop working completely.

Check Your Wires And Connections

A benefit of choosing solar street light is that you do not have to worry about burying electrical wires, but there are still wires that may need your attention. If your fixtures are separate from the solar panels, you will have a wire connecting the two parts that may be chewed by wildlife or pets. The more common case is simply having interior wires connecting your on-fixture solar panel to the batteries. Although this wire is pretty protected, it still may be possible for wildlife to access it and chew through the wires.
Therefore, you should check for any possible damaged wires and broken connections every three to six months. By following this step, the lifespan of your solar street light will be significantly increased. 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.


Solar street lights are quite simple to use, but like all other electric appliances, they need to be used with care. It is important for users to carefully maintain the solar street light so that they can work for a longer time.
