Solar street lamp maintenance

1. The quality of solar panels is directly related to the overall application. Rural solar street lamps must pass the certification of photovoltaic cell modules provided by specific units. Solar street lamp manufacturers have used some small factory control panels, but there is one case where the lights are on after dark, which is one hour earlier than the solar street lamp of reliable manufacturers. In this case, the conversion efficiency is very low, and the power generated cannot reach its nominal power, which cannot meet the needs of consumers for the duration of lighting fixtures. The control panel was resolutely replaced.
2. The production and manufacture of solar street lamp poles must do a good job in storm water treatment. In the production of solar street lamps in rural areas, solar street lamp manufacturers should make solar street lamps that can withstand local wind pressure by measuring different wind pressure according to the size of solar panels. The hot-dip galvanized electrostatic spray plastic shall be used, and the design perspective of the battery module support frame shall be combined with the local level. Waterproof and rainproof RF connectors should be selected at the connection and wiring positions between the support frame and the branch pole to avoid rainwater flowing into the control board and rechargeable battery along the road, resulting in inter pole short circuit faults and damage to components.
3. The LED light source of rural solar street lamps should have reliable peripheral circuits. The software working voltage of solar street lamp is usually 12V or 24V. Common light sources include energy-saving lamps, high and low pressure sodium lamps, electrodeless lamps, porcelain metal halide lamps and LED lamps. Except for LED lamps, any other light source shall be a low-voltage DC electronic rectifier with high reliability. Cooperate closely with various light source manufacturers to conduct many functional tests at the production site, and select more reliable light sources to market. See the whole process from dark to light, from light decay to very serious light decay to very small.

Although the light decay of LED has its physical characteristics, the rural solar street lamp should choose the LED lamp beads with high cost performance and high power. At the same time, the constant current power regulator LED special control circuit should be made to manipulate the amount of current used at different stages, so as to achieve better environmental protection and energy saving practical effect.
