In the street lamp industry, more and more people are choosing solar street lights to utilize energy and save costs. The market for solar street lights is diverse, with various manufacturers and prices. Some individuals may be unsure how to select the appropriate solar street light. Here are some guidelines from Century Sunshine on how to properly choose solar street lights for new rural areas.
Choosing solar street lights can be done through the following methods:
I. Height Selection
The height classification is based on the required height of the solar street light. Different heights correspond to varying thicknesses of the Q235 galvanized pipe and different price points. Common solar street light heights are 6 meters, 7 meters, 8 meters, 10 meters, and 12 meters. Regular areas typically utilize 6-8 meter street lights with a general thickness of 2.5 millimeters. As long as the foundation is constructed properly, this thickness provides sufficient wind resistance. Thicker options of 2.75 millimeters, 3.0 millimeters, and 3.2 millimeters result in corresponding price increases. For example, in residential areas or on four-lane, two-lane, and rural roads, 6-8 meter and 2.5-2.75 millimeter solar street lights suffice.
II. Battery Selection
Currently, conventional battery classifications include gel lead-acid batteries and lithium iron phosphate batteries. Initially, most people chose lead-acid batteries due to their heavier weight. For convenience and safety, they opted to bury the batteries next to the street lamps, but these were often stolen after installation. Because of this, lithium batteries have emerged as they are smaller, more convenient, quicker to install, and energy-efficient. They can be directly secured beneath the solar panels and placed behind the LED lamp heads, thus enhancing their safety.
III. Parameter Selection
For solar smart street lights, characteristics such as light source wattage, solar panel size, and battery size are categorized. Regular LED solar street light wattages range from 20W to 120W. Generally, high-power lights are used for urban six-lane and eight-lane roads, typically at a height of 9-12 meters. For different manufacturers, the specifications of the light source, batteries, and solar panels are fixed, differing only by brand. One cannot choose a 30W solar street light while requiring a 60W solar panel and battery, as this leads to wasted resources and money. Selecting a high-power light source along with smaller solar panels and batteries to cut costs may lead to insufficient charging during the day or overcharging, resulting in inadequate lighting at night or on rainy days, significantly affecting user experience.
The above are some reference conditions for selecting solar LED street lights introduced by Century Sunshine. When purchasing rural solar street lights, consider the points mentioned above.
