The main difference between new energy LED street lamp and conventional street lamp is the different power supply. The power supply system of new energy LED street lamp is composed of solar cell module, wind turbine, battery and controller, which brings great difficulties to daily maintenance because of its standard, component quality and installation method. The use and maintenance of new energy LED street lamps directly affect the service life of new energy LED street lamps, and affect the operation cost and work efficiency of new energy LED street lamps. To do a good job in the maintenance of new energy LED street lamps is the best means to maintain their good operation.
- Solar cell maintenance
Solar energy battery components depends on the life of a packaging format, strictly made of laminated technology qualified service life of the solar energy battery components can be up to 25 ~ 30 years, but now China’s production of solar energy battery components “glue” the vast majority of using epoxy resin encapsulation, in the sun under the irradiation of ultraviolet, epoxy resin will be yellow, white, The life of solar cell module is only 1~2 years, even if the modified epoxy resin encapsulation can make the life of more than 2 years, but still can not meet the requirements of use, and some even can not reach the “energy recovery period”. Even if some solar cell modules use laminating process, but these solar cell modules use poor light transmittance of ordinary glass and EVA packaging materials such as poor, coupled with not strictly in accordance with the process requirements for packaging, service life more than 4~5 years is not much.
Solar energy battery components made from a mix of multiple solar cells, in the process of use if there is a solar battery obscured alone, separate obscured under the irradiation of solar cells in the bright sunlight will heat damage, and then cause the damage of the solar cell components, this is the so-called “heat island effect”, even if will be tilted solar cell components, And the addition of anti-bird needle, also can not completely prevent leaves, bird droppings or other shielding objects attachment, which requires the staff to often clean the solar cell module. In addition, periodically check the tightness of all installation components. In case of abnormal weather such as hail, wind, or rainstorm, take protective measures to prevent damage.
The daylighting surface of the solar cell module should be kept clean often. If there is dust or other dirt, it should be washed with water first, and then gently dry the water marks with clean gauze. Do not wash or wipe with hard objects or corrosive solvents. When the road surface is often large vehicles carrying muck through, the road surface is often dusty, and the air is often dusty. In such an environment, the maintenance personnel of the new energy LED street lamp should observe the battery module of the new energy LED street lamp regularly. When the surface area of the solar cell module is observed to reach gray, If the original blue crystalline surface of the solar cell module is not clear, the solar cell module should be cleaned and dedusted in time. In order to avoid insufficient absorption of light by the solar cell module, the battery will not be charged enough, thus affecting the service life of the battery. New energy LED street lamps should be cleaned and dusted regularly according to the installation environment:
(1) General rural road surface: five to six months to clean once is appropriate.
(2) Urban street pavement: three to four months to clean once is appropriate.
Use a safe step ladder to remove dust. Do not directly climb the new energy LED street lamp pole. Available dry, clean cotton dry mop first sweep dust, and then wet clean cotton mop mop mop clean.
