The standard warranty for a complete solar street light system typically ranges from 2 to 5 years. However, because different components have different lifespans, the coverage is often split:
| Component | Standard Warranty | Expected Lifespan |
| Solar Panel | 10 – 25 years | 25+ years |
| LED Light Source | 3 – 5 years | 50,000+ hours |
| Lithium Battery | 2 – 5 years | 5 – 8 years |
| Controller | 2 – 3 years | 8 – 10 years |
| Steel Pole | 10 – 20 years | 20+ years (if galvanized) |
If your solar street light fails to operate correctly, follow these standard industry procedures:
Before contacting the manufacturer, check for simple issues:
Cleaning: Ensure the solar panel isn't covered by dust, snow, or bird droppings.
Obstructions: Check if new tree branches or buildings are shading the panel.
Battery Cycle: If it has been raining for several days, the battery may simply be depleted and needs a full sunny day to recharge.
Manufacturers require evidence to process a claim. You should:
Take clear photos or videos of the light (both during the day and at night).
Record the Serial Number (S/N) usually found on a sticker on the pole or inside the light head.
Locate your Proof of Purchase (Invoice or Contract).
Reach out to the supplier with your documentation.
Under Warranty: If the failure is due to a manufacturing defect, the supplier will typically send replacement parts (like a new battery or controller) free of charge. You may be responsible for the labor cost of the installation.
Out of Warranty: The supplier will provide a quote for the necessary replacement parts and technical guidance for the repair.
Most modern solar street lights are modular. You usually do not need to replace the entire unit. Replacing just the battery or the controller is often enough to restore the light to full functionality.
