Now, in cities and towns, solar street lights can be seen everywhere on both sides of the road, mainly because it is green, does not require electricity and is easy to install. But how should solar street lights be selected? The prices of solar street lights on the market are different, and these 4 points are enough.
1. Select the light source
solar street light configuration First determine the power of the lamp, the solar street light uses LED light source, and the most used is 1W high-power lamp beads, generally a power is 1W, and some use low power such as 2835 or 5070 and other low-power lamp beads. Rural road lighting is generally 30-60 watts, and urban expressways need more than 60 watts. If the LED light source exceeds 120 watts, it is not recommended to use solar power, because the configuration is too high and the cost is high.
2. Solar panels
Solar panels are divided into single crystal and polycrystalline. The price of single crystal is higher than that of polycrystalline. Since customers do not have professional measuring instruments when purchasing, it is recommended to use size area to measure. The larger the size area, the larger the size of the solar panel and the The power of the solar panel is proportional. Select the appropriate solar panel and battery according to the lamp power and sunshine duration, which should be obtained through scientific calculation.
3. Battery
Solar street light batteries are generally divided into three types: lead-acid batteries, ternary lithium batteries and lithium iron phosphate batteries. The lithium iron phosphate batteries generally seen on the market are second-hand or disassembled 32650 cylindrical batteries, and lithium iron phosphate is currently commonly used. Batteries and lithium batteries, the cost of phosphoric acid batteries is higher than that of lithium batteries, the cost of lithium batteries is higher than that of lead-acid batteries, and the most popular is second-hand block batteries.
4. Street light pole
The street light pole mainly considers the upper and lower diameter, height, thickness, shape and surface treatment. The larger the diameter or the higher the height and the thicker the thickness of the street light pole, the higher the price; the more complex the shape of the street light pole, the higher the price; the surface The overall cost of hot-dip galvanizing treatment is higher than that of hot-dip galvanized sheet, and the cost of hot-dip galvanized sheet is higher than that of cold galvanized sheet; the cost of plastic spray treatment is higher than that of surface painting.
