How to Choose LED Solar Lamps

1. Solar Panel Efficiency
Highly efficient solar panels can convert sunlight into electricity more efficiently. Usually use monocrystalline or polycrystalline solar panels. High-efficiency solar panels can ensure that they can still charge when the sunlight is weak. Check the power (W) of the solar panel. The higher the power, the stronger the ability to absorb sunlight.
2. Battery capacity and quality
Solar lights usually use lithium batteries. Lithium batteries have a longer service life and high charging efficiency. Check the battery capacity (mAh or Ah). A large capacity means that the battery stores more energy and the lamp can last longer on days without sunlight. The quality of the battery is also important. Low-quality batteries may cause incomplete charging or short service life.
3. Light source quality
Solar lights generally use LED lamp beads. Check the brightness, life and light efficiency of the LED. High-quality LED lamps have stable brightness, moderate color temperature, and are not easy to decay.
4. Waterproof and dustproof level
Solar lights are usually used outdoors and must have a good waterproof and dustproof design, which can usually be checked by IP level (such as IP65, IP67). The higher the IP rating, the better the waterproof and dustproof performance of the product.
5. Materials and workmanship
The shell material of the solar lamp is preferably made of weather-resistant aluminum alloy or high-strength plastic, which can avoid oxidation or corrosion caused by long-term exposure to the external environment. Good quality products usually have fine workmanship, the lamps are tightly connected, and the interface parts are not easy to loosen.
6. Working time and brightness
High-quality solar lamps generally provide longer working time, usually maintaining good brightness all night (6-12 hours).
Check whether there is a dimming function. Some solar lamps will automatically adjust the brightness according to the ambient light, saving energy while extending the use time.
7. After-sales service and brand reputation
Some well-known brands of solar lamps are usually more reliable in quality. Check the product’s warranty period and after-sales service to see if they can provide effective technical support and repair services.
