As an emerging new energy technology, solar street lamps are favored by more people because of their energy conservation and environmental protection, and quickly occupy the market. The biggest advantage of solar street lamps is to use sunlight to generate electricity without electricity, and it is simple to install and low to maintain. If you need to buy street lamps, here are some suggestions from Mujing manufacturer.
1、 Height selection
The height is determined relative to the width of the road. The thickness of Q235 galvanized pipe varies with the height. Common solar street lamps are 6m, 7m, 8m, 10m and 12m. Street lamps with a height of 6-8m and a thickness of 2.5mm can be selected for conventional roads. As long as the embedded parts are reasonable in structure and have certain wind resistance, 10mm, 18mm and 24mm can be used. For example, in residential areas, or on four lane, two lane and rural roads, 5-6m and 7-9m solar street lamps are sufficient.
2、 Battery selection
Batteries are divided into colloidal batteries, ternary lithium batteries and lithium iron phosphate batteries. Colloidal batteries are large in volume and short in life. They are easy to be stolen when buried underground and are basically eliminated. The ternary lithium battery has high voltage and good power characteristics, but its safety is poor. Lithium iron phosphate battery is a commonly used battery for street lamps at present. It is characterized by long life, up to 8-10 years, more than 2000 charging and discharging times, and high safety performance. Lithium iron phosphate battery is small in size. It is directly fixed under the solar panel or installed in the lamp cap, thus improving its safety factor of use.
3、 Parameter selection
The parameters of solar street lamps include the wattage of light source, solar panel size, battery capacity and voltage. While the wattage of conventional solar street lamps is 20w-60w, 80W, 120W. Generally, high-power street lamps are used in six lane and eight Lane cities, with a height of 9-12 meters.
The commonly used solar panel power is 50W, 60W, 80W, 100W, 120W, and the area is proportional to the power, that is, the power is as large as the size. Solar panels with the same wattage can have different voltages. For example, 50W solar panels can have 5V 6V 9V 18V.
The capacity of the battery is 40ah, 60ah and 80ah. The voltage includes 3.2V, 6.4v, 11.1v, 12V, 24V, etc. the power calculation formula is: ah*v=wh, for example, 40ah*3.2v=128wh (watt hour)
