1. Product & Technology

Q1: What is an all-in-one/integrated solar street light? How does it differ from a split system?
A: An all-in-one solar street light integrates the solar panel, LED lamp, battery, and smart controller into a single compact unit. Unlike split systems with separate components, our integrated design allows for easier and faster installation (often under 30 minutes), lower maintenance (no wiring between parts), and a sleeker appearance. It's the ideal plug-and-play solution for most projects.

Q2: What is the working principle? Will it work on cloudy/rainy days?
A: The panel converts sunlight into electricity to charge the battery during the day. At night, the battery powers the high-efficiency LEDs. Our lights are designed with 3-5 days of autonomy, meaning they can operate normally through consecutive cloudy/rainy days. Battery capacity and panel size are calculated based on your local weather data.

Q3: What are the key components and their specifications?
A: Our core components ensure top performance:

• Solar Panel: High-efficiency monocrystalline silicon, 22%+ conversion rate.

• Battery: Long-life LiFePO4 (Lithium Iron Phosphate) battery, 2000+ deep cycles.

• LED Chip: Branded chips (e.g., Philips/Bridgelux) with 50,000+ hours lifespan.

• Controller: Smart MPPT/PWM controller with PIR motion sensor and light control+time control modes.

• Protection: IP65/IP66 waterproof & dustproof rating; IK08 anti-vandalism.

Q4: How long does the battery last, and what is the lifespan of the light?
A: The LiFePO4 battery typically lasts 5-7 years under normal use. The overall system lifespan is 8-10 years, with LEDs maintaining over 70% of initial lumen output. 

2. Installation & Application

Q5: How easy is the installation? Do I need an electrician?
A: Installation is very straightforward. Our lights are pre-assembled and pre-wired. You only need to mount the light onto a pole (using the provided bracket), ensure the panel faces south (in the Northern Hemisphere), and switch it on. No trenching, cabling, or licensed electrician is required, drastically reducing installation costs.

Q6: What factors should I consider when choosing the right model?
A: Key factors are:

• Required Illumination Area: Determine the Lux level and coverage needed (e.g., road width).

• Local Weather Conditions: We calculate peak sun hours for your location.

• Backup Days Needed: Standard is 3 days; can be customized.

• Pole Height & Mounting: We provide compatible brackets.
  
  

Q7: Can it work in extremely cold (or hot) climates?
A: Yes. Our LiFePO4 batteries have an excellent operating temperature range (-20°C to 60°C / -4°F to 140°F). We use high/low-temperature cut-off protection in the controller and industry-grade materials to ensure performance in harsh environments.

3. Ordering, Shipping & Warranty

Q8: Do you offer OEM/ODM and customization?
A: Absolutely. As a professional manufacturer, we offer extensive customization:

• OEM: Your logo and packaging.

• ODM: Adjust power (20W-200W), battery capacity, light color, sensor settings, and pole design.

• Project-Based Solutions: Tailored systems for large-scale municipal tenders.
  
  

Q9: What is your lead time and shipping terms?
A: Standard models: 7-15 days. Customized orders: 15-30 days. We ship worldwide via sea/air/express. Common terms are FOB, CIF, or DDP, depending on your preference and location. Our logistics team handles all documentation.

Q10: What is your warranty policy?
A: We offer a comprehensive 3-5 years warranty on the entire system. The warranty covers manufacturing defects. We provide technical support and a clear troubleshooting guide. Spare parts are available for long-term maintenance.

4. After-Sales & Support

Q11: What if I have technical issues after installation?
A: We provide:

• Detailed user manuals and installation videos.

• Remote troubleshooting via email/WhatsApp.

• For critical issues, we can ship replacement parts promptly.

Q12: Can you provide CE, RoHS certificates and test reports?
A: Yes. All our products are fully certified (CE, RoHS, IP65, etc.). We provide digital copies with the shipment and original documents upon request. We can also assist with specific country import certifications.
