Yes. We provide specialized batteries for extreme climates, including heating films for cold regions and heat-resistant lithium cells for tropical environments.
The initial purchase price is slightly higher, but considering zero electricity bills and zero cabling costs, the Return on Investment (ROI) is typically achieved within 2 years.
We use reinforced cartons and wooden pallets to prevent damage during long-distance transit. For large projects, we recommend FCL (Full Container Load) sea freight to minimize shipping costs.
We offer a 3-5 year full-system warranty. If a quality issue arises, we will ship free replacement parts immediately after verification.
Our solar street lights carry CE, RoHS, IP66, IK10, and ISO 9001 certifications, meeting the standards for government and commercial projects worldwide.
Yes. We can customize power output, battery capacity, logo branding, and even industrial design based on your project requirements.
In dusty or low-rainfall areas, we recommend cleaning every 6 months. Heavy dust accumulation can reduce charging efficiency by over 20%.
This is usually due to battery aging, panels being shaded causing insufficient charge, or incorrect controller settings. We can assist you with remote troubleshooting.
LED Fixture: >50,000 hours; Solar Panel: 25 years; Lithium Battery: 5-8 years; Controller: 5-10 years.
No. It is a self-contained power system that requires no trenching, wiring, or grid connection, significantly reducing installation and labor costs.
The optimal angle depends on your local latitude. Generally, panels should face the equator (South in the Northern Hemisphere) at an angle equal to your latitude plus $5^{\circ}$ to $15^{\circ}$.
We primarily use LiFePO4 (Lithium Iron Phosphate) batteries. Compared to Gel or Lead-acid batteries, LiFePO4 offers a much longer cycle life (over 2000 cycles) and superior high-temperature resistance.
Monocrystalline panels offer higher efficiency (above 20%) and perform better in low light, making them ideal for all-in-one designs. Polycrystalline panels are more budget-friendly for large-scale projects.
Yes. Our systems are engineered with "Autonomy Days," typically supporting 3-5 consecutive days of illumination even in complete absence of direct sunlight.
Our products are designed to illuminate for 10-12 hours per night. With intelligent controllers, we can customize lighting modes, such as full power for the first 4 hours and energy-saving mode thereafter.
