BrightGridSolar systems contain several different components, and each can have different warranty terms. Understanding the difference between product warranties, performance warranties and installation workmanship warranties can help you compare quotations properly.
Product warranty
A product warranty generally covers defects or faults associated with the manufactured component. The duration and exclusions depend on the manufacturer and product.
Performance warranty
A performance warranty describes expected electrical output over time. Solar panels naturally degrade, so the warranty can specify the minimum expected output after particular periods.
Installation workmanship warranty
The installer may provide a separate warranty covering workmanship and installation-related issues. This is different from the panel manufacturer's warranty.
| Warranty | Usually concerns |
|---|---|
| Product | Manufacturing defects |
| Performance | Long-term generating performance |
| Installation | Installer workmanship |
| Inverter | Inverter equipment |
| Battery | Battery performance and capacity subject to terms |
What should you check in the warranty?
- Warranty duration
- Who provides the warranty
- Registration requirements
- Transferability
- Exclusions
- Claim process
- Performance conditions
- Geographical limitations
A long warranty is only useful if you understand the terms
Compare the actual warranty conditions rather than choosing equipment solely because a headline warranty period looks longer.
Compare your solar system options
Review equipment, warranties and installation scope before choosing your system.
