In the pursuit of a green, low-carbon modern society, solar street lamps, with their clean and environmentally friendly characteristics, have become the top choice for urban lighting. However, with the abundance of solar street lamp products on the market, how can you choose a reliable product? Let's explore the key points for purchasing solar street lamps below.
Generally, the power of a solar panel depends on its size. When the prices of two solar street lamps vary greatly, first compare their solar panel sizes.
Monocrystalline solar panels have a 20% higher efficiency than polycrystalline solar panels of the same size.
The most effective way to test the quality of solar panels is to use a solar simulator (IV tester) and a solar cell defect tester (EL tester), similar to an X-ray examination of the solar panel to detect potential defects.
MPPT controllers have higher efficiency than PWM controllers but are also more expensive.
IP indicates the waterproof rating of the controller, which is crucial for the lifespan of the controller. Bare board controllers without waterproof treatment have a much shorter lifespan compared to high waterproof rated controllers.
Batteries are key to the cost and supplier quotations; they are the most complex part of a solar street lamp.
Currently, the most commonly used batteries on the market are lithium iron phosphate and ternary lithium batteries. Due to the high temperature within the lamp body, lithium iron phosphate batteries are the best choice for solar street lamps, especially in areas where the maximum annual temperature exceeds 40°C.
The capacity of the battery is the biggest gray area in the cost of solar street lamps. Buyers have difficulty effectively testing battery capacity, which gives unscrupulous merchants the opportunity to falsely report battery capacity and deceive buyers.
Even if two suppliers use lithium iron phosphate batteries with the same capacity, different battery grades/ qualities can lead to significant differences in cost, product quality, and lifespan.
Low-priced products may use used batteries, leading to unpredictable lifespans.
Different suppliers use different LED light beads, resulting in different costs.
More light beads do not mean higher wattage. The actual power determines the illumination of solar street lamps, not the number of LEDs.
Proper cooling and heatsinking are crucial for LED light sources. LED modules without heatsinks will experience rapid light decay, accelerated aging, a quick reduction in brightness, and a significantly shortened lifespan.
The aluminum substrate is the basic circuit board for LED modules, welded to LEDs using SMT technology. Different qualities of MCPCB can result in cost differences of up to 2 times or more. Aging is a key procedure for all electronic products, but currently, the majority of suppliers in the market do not perform aging, or their aging time is far below the industry standard of 12 hours.
Professional solar street lamps should have professional IES optical design, and the IES type should meet the project requirements.
High-quality solar street lamps use aluminum alloy housings, whereas low-priced street lights use iron or plastic housings.
High-quality solar street lamps use 304 stainless steel screws and anti-corrosion bolts; street lights installed by the sea use 316 screws.
For professional solar lighting projects, the rationality and stability of the lamp body structure should be considered, not the shape. Compared to brightness, quality, and lifespan, appearance is the last factor to consider.
Through the above detailed comparison and analysis, we hope that when purchasing solar street lamps, you can choose a truly reliable product and contribute to the green and environmental protection cause.
