Yufai：How to choose a suitable solar power street lamp?

Now, in cities and towns, the rural solar power street lamps that can be seen everywhere stand on both sides of the road, mainly because it is environmentally friendly, does not require electricity bills, and is easy to install. But how should rural solar street lamps choose? The prices of rural solar power street lamps on the market are different, so these 4 points are enough.

1. Select the light source: determine the power of the lamp in the rural solar power street lamp configuration. The rural solar power street lamp 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 require more than 60 watts. If the LED light source exceeds 120 watts, solar power is not recommended because the configuration is too high and the cost is high.

2. Solar panels: solar panels are divided into monocrystalline and polycrystalline. The price of monocrystalline is higher than that of polycrystalline. Since customers do not have professional measuring instruments when purchasing, it is recommended to use the size area to measure. The larger the size area, the solar panel The larger the size is proportional to the power of the solar panel. Choose suitable solar panels and batteries according to the power of the lamp holder and the duration of sunshine, which requires scientific calculations to obtain the parameters.

3. Batteries: Rural solar power street lamp batteries are generally divided into three types: lead-acid batteries, ternary lithium batteries and lithium iron phosphate batteries. The lithium iron phosphate batteries commonly seen on the market are second-hand or disassembled 32650 cylindrical batteries. Currently, lithium iron phosphate batteries and lithium batteries are commonly used. The cost of phosphate batteries is higher than that of lithium batteries, and the cost of lithium batteries is higher than that of lead-acid batteries. The cheapest is second-hand block batteries.

4. Street light pole: The main consideration is the upper and lower caliber, height, thickness, shape and surface treatment of the pole. The larger the caliber or height and the thicker the thickness of the pole, the higher the price; the more complex the shape of the pole, the price It will also increase; the overall cost of surface treatment of hot-dip galvanizing is higher than that of hot-dip galvanized sheet, and the cost of hot-dip galvanizing is higher than that of cold-dip galvanizing; plastic spraying is higher than the cost of surface painting.
