How to extend the service life of solar street lighting system?

        Normally,solar street lighting system have 8-10years service life.Some solar street lighting is lack of maintain,so only can have around 5years service life.So how to do can extend the service life of solar street lighting system?

        Firstly,extend the service life of solar street lighting system need to cleanness lighting’s solar panel surface.If in your area,it have wide range of rain and sand,should be cleaned once a month.The solar panel should be washed with water first, then wipe the water marks with a soft cloth, do not use corrosive solvents to clean or wipe with a hard object.It will be better to do the clean work in morning,evening or another time which in the absence of sunlight. Perhaps it should be avoided in the daytime to use solar photovoltaic modules, clean the components with cold water, cold water will break the glass cover of the photovoltaic modules.In winter,if the temperature is low,it will be better not to pour the water,just use clean wet cloth rub the solar panel surface,in case the solar panel glass burst.

        Secondly,extend the service life of solar street lighting system need to check the connection between the photovoltaic panels is robust in a fixed time,mostly during 3months or 6months. Check the square box wiring is robust or not, and the PV modules are checked for damage or malfunction as needed. If broken, the gate line disappears and is hot. The bypass diode junction box checks for proper operation of the normal components of the PV module.When there is a problem, replace it in time, and record the parts of the specific orientation of the PV array. In order to extend the service life of solar street lighting system,it need to do some maintain work.The maintain work cost few worker salary,but it can ensure the solar street lighting system high efficiency and stable work longer time,so it is worth.
