Frequently Asked Questions

FAQ 1: How does a solar street light work？

Answer: A solar street light operates as a standalone off-grid lighting system. During daylight, the solar panel absorbs sunlight and converts it into electrical energy, stored in the rechargeable battery (typically LiFePO4). When dusk arrives, a smart MPPT controller automatically turns on the LED light. Most modern solar lights provide 3-5 days of backup in cloudy/rainy conditions.

FAQ 2: What is the difference between all-in-one and semi-integrated solar lights?

Answer: All-in-one: Integrates panel, battery, LED, and controller into a single unit. Easy installation, sleek design, but limited to lower wattages (30W-150W). Semi-integrated (split-type): Separate components connected by cables. Larger capacity, higher wattages (30W-300W), easier maintenance. Our Spread Wings ZC series offers a hybrid design.

FAQ 3:  How long do solar street light batteries last?

Answer: LiFePO4 (Lithium Iron Phosphate): 2,000-4,000 cycles → approximately 5-8 years. Lithium-ion (NMC): 1,000-2,000 cycles → 3-5 years. Lead-acid/GEL: 500-800 cycles → 2-3 years. All SX-brand solar lights use Grade A LiFePO4 batteries with 3-year standard warranty (5-year optional).

FAQ 4: Can solar lights work in cloudy or rainy weather?

Answer: Yes! All Jiangsu Shixin solar street lights are designed with 3-5 days of autonomous operation during consecutive cloudy or rainy days. The MPPT controller optimizes charging even in low-light conditions. For areas with prolonged monsoons, we recommend increasing solar panel and battery capacity by 30-50%.

FAQ 5: What is the installation height?

Answer: 30-50W: 5-6m / 100-200m². 60-100W: 7-8m / 200-400m². 100-200W: 8-10m / 300-500m². 300-500W: 10-12m / 400-800m².

FAQ 6: What is the warranty on solar street lights?

Answer:  We offer: 3-year standard warranty on the complete light (LED, controller, battery) and 5-year extended warranty available at extra cost. The LED light source carries 50,000+ hours lifespan. For CCTV-integrated models, the camera carries a separate 2-year warranty.

FAQ 7: Are solar lights bright enough for main roads?

Answer: Yes. Our 300W-500W models produce 10,000-26,000 lumens, sufficient for main roads and highways. For example, SX-SS500P (500W) outputs 10,000-13,000lm, suitable for 6-10m installation height. We provide free Dialux lighting design to verify illumination meets your project standards.

FAQ 8: What is the smart control system?

Answer: All our solar lights feature MPPT (Maximum Power Point Tracking) controllers for optimal charging efficiency. Additional smart features: Remote control (on/off/dimming), Timing control (3+8h, 5+5h, full night), Auto dimming (saves power when battery is low), Motion sensor (PIR radar, dim to 30% when no motion, 100% when detecting movement).

FAQ 9: Can I get samples before bulk order?

Answer: Small poles (4-6m): Bundles with steel straps, plastic wrapped. Medium poles (7-9m): Loaded into 20GP/40HQ containers. Large poles (10m+):Yes! We accept sample orders with express delivery (7-10 days via DHL/FedEx). Sample prices are slightly higher than bulk MOQ prices. Sample cost is deductible from the bulk order. MOQ for mass production is typically 50 pcs per model.

FAQ 10: What is the IP rating?

Answer: All our solar street lights are rated IP66 (dust-tight and protected against powerful water jets), suitable for outdoor use in all weather conditions. The battery compartment is IP67 rated for underground installation.

FAQ 11: Do you provide installation instructions?

Answer: Yes, each order includes a detailed installation manual with step-by-step instructions and diagrams. For all-in-one models: mount pole, attach fixture, connect cable. For semi-integrated: mount solar panel, install battery box, connect cables. Most installations take 20-30 minutes per light for experienced workers

FAQ 12: What is the color temperature of the LED?

Answer:Our standard LED color temperature is 6500K (cool white/daylight), which provides the best visibility for street lighting. We also offer 5000K (natural white) and 3000K (warm white) options for decorative or residential areas. The LED light source uses Bridgelux/Samsung chips with ≥140lm/W efficacy.

FAQ 13: Do solar lights work in cold climates?

Answer:Yes. Our LiFePO4 batteries operate in -20°C to 60°C. For extreme cold regions (below -20°C), we offer low-temperature LiFePO4 batteries with built-in heating function. The LED light source itself is unaffected by cold temperatures. Solar panel efficiency actually increases slightly in cold, sunny conditions.
