How to choose solar street lights for rural area?
Street lights cannot be judged solely by the suitability of solar powered street lights, but also by considering many other factors, such as the selection of lamps, lamp poles, installation methods, and precautions.
So How to choose solar street lights for rural area?
1. Choose the appropriate height and galvanizing method for solar street light poles
What we need to consider is the height of solar street lights. It is crucial to choose a solar street lamp with a height of several meters in rural areas, as many rural streets are filled with power lines. Therefore, it is important to consider whether the height of the solar street lamp may pose a safety hazard to the lines. Based on experience, solar street lamps with a height of 5-6 meters are precisely suitable for the on-site situation in rural areas.
Solar street lights must withstand wind and sun all year round, and it is best to use hot-dip galvanized materials, which can be used for more than 20 years without rusting.
2. Consider the lighting duration of solar street light poles
It is necessary to carefully check the power, wattage, and battery capacity of solar panels. Currently, many defective manufacturers have falsely marked wattage and battery capacity, which can lead to low lighting duration or brightness. You can first purchase a sample for actual testing to see if it meets your expected results, and then purchase in large quantities.
Nowadays, solar streetlights can be lit regularly or frequently all night, and some also have human body sensing function, which can be set according to the actual situation in the village.
3. Choose iron sheet lamp beads:
Nowadays, there are generally two types of lamp beads on the market: SMD lamp beads or imitation lumen lamp beads. Imitation lumen lamp beads have been phased out in the market, and now manufacturers mainly use SMD lamp beads, which have the characteristics of durability, long service life, low energy consumption, safety, low voltage, and colorful lamps.
4. Select Lithium iron phosphate battery:
At present, the conventional battery classification is colloidal lead-acid battery box Lithium iron phosphate battery. At the beginning, everyone chose lead-acid batteries, which are bulky. For convenience and safety, they chose to bury them next to street lamps. After construction and installation, the development batteries were stolen some time later. For this reason, lithium batteries have emerged, which are relatively small, convenient, fast, and energy-efficient. They are directly fixed under the solar panel and placed directly in the LED street lamp holder at the back, improving its safety factor of use.
Lithium iron phosphate battery has high specific energy, small size, fast charging, long service life, good stability, and of course, the highest price. The cycle charging frequency is about 1500-2000 times, with a long service life, usually up to 8-10 years. It has strong stability and a wide temperature range, and can be used between -40 ℃ and 70 ℃, even in winter Severe cold areas.
5. Calculate the spacing between solar street lights
Solar street lights with a distance of 5-6 meters are spaced between 20 meters and 30 meters, which provides good lighting effects. At the same time, adjustments should be made according to the actual situation in rural areas, but it is worth noting that the sunlight must be able to shine on the solar panels.
6. Select the floor cage and install it:
The most easily overlooked point is the thickness and size of the ground cage of the lamp pole. The thicker the ground cage, the more stable the thickness of the lamp pole will be, and the better the wind and earthquake resistance effect.
At the designated location for installing streetlights, excavate the streetlight foundation pit based on the height and width of the ground cage, with the pit slightly wider than the width of the ground cage.
If the surface soil is soft, the excavation depth should be deepened and other facilities at the excavation location should be confirmed and protected.
Choosing the right lighting fixtures and poles is only the first step, and more importantly, installation. To maximize the effectiveness of street lights, it is necessary to adapt to local conditions and choose the most suitable installation distance
