Six criteria for choosing quality solar lights

To ensure a solar lighting project achieves high performance, stable operation, durable lifespan, optimal efficiency, and cost-effectiveness, the most crucial factor is selecting high-quality solar lighting products with modern technology that meet technical specifications and safety standards.

1. Clear, detailed, reliable technical specifications:

When purchasing any solar lighting product, customers should carefully examine the product information and technical specifications, as these crucial details significantly impact the performance and durability of the lights:

+ LED Chip, Luminous Flux (Light Intensity), and LED Lifespan

Quality lights typically use LED chips from renowned brands such as Lumileds (Philips) from the Netherlands, Bridgelux from the U.S., Osram from Germany, with a luminous flux of around 170lm/W and an LED lifespan of 50.000 hours.

+ Solar panel

Reputable manufacturers usually opt for mono-type solar panels with cell efficiency of 20% or higher, and panel power equal to or greater than twice the light power.

+ Storage battery

Lithium LiFePo4 batteries are commonly used, with a storage capacity 10-14 times the light power to ensure illumination for 2-3 days during prolonged rainy periods.

The major global brands always declare the capacity of storage batteries in units of Wh, while some use mAh or Ah as the unit. For measurements in Ah, customers need additional information about voltage (V) to calculate capacity (Wh) and lighting duration.

Storage battery capacity (Wh) = voltage (V) x capacity (Ah).

It’s essential to pay attention to other components like motion sensors, controllers, etc.

2. Application of modern technology, smart controls:

To optimize functionality, extend lifespan, and introduce additional convenient features, modern solar lights continuously undergo improvements, incorporating new technologies and smart controls, such as scheduled lighting modes.

Smart controllers enable the lights to automatically turn on at dusk and off at dawn. They allow brightness customization, activity monitoring, charge/discharge control to extend battery life, protect against overloads, and maximize solar panel efficiency.

Some newer products also incorporate Microwave sensor technology, gradually replacing traditional PIR sensors, providing faster motion detection and automatically adjusting brightness levels in real-time when movement is detected.

3. IoT monitoring system integration:

To facilitate remote monitoring, receive automatic error alerts for timely troubleshooting, and control solar lighting systems from a distance, an IoT monitoring solution based on 4G communication protocol and Zigbee communication is a highly effective and necessary choice, especially for large-scale lighting projects.

4. Clear country of origin, complete CO, QC certifications:

Many solar lighting products on the market lack brand labels, clear technical specifications, and have virtual light power ratings at various price points. Therefore, before deciding to purchase or deploy solar lighting projects, customers should thoroughly research the products, choose reputable brands specializing in solar lighting production, ensuring clear country of origin, full technical specifications, and certification with CO, QC to ensure high-quality products.

5. International standards compliance (CE, IEC, RoHS, etc.):

In addition to CO, QC certifications, solar lights should comply with international safety standards, be approved for circulation in most countries worldwide, and use environmentally friendly materials. Especially, standards tested, evaluated, and certified by European agencies.

6. Warranty and replacement in Vietnam

Most solar lighting products on the market are manufactured and processed abroad. Therefore, when searching for solar lighting products, customers should choose products with genuine warranties in Vietnam, with a warranty period of 3 years or more.

With these six criteria outlined in the article, customers can choose products that not only guarantee quality but also deliver efficient functionality, durable lifespan, and fully utilize the superior advantages of solar lighting.

To assist customers in meeting these criteria, DAT Solar introduces the NOVA 60W solar street light series from the Sokoyo brand, known for its high-quality standards.
