The designed usage time for solar cell modules is about 20~30 years. Reliability testing simulates the earth's surface photovoltaic modules (crystalline silicon and amorphous silicon thin film, concentrating) design verification, ensuring the module can operate long-term for more than 20 years in a general climate. The specification requires solar cell modules to undergo the following tests:
| Standard | High Temp. High Humidity | Low Temp | Temp. Change Rate | Cycle No. |
|---|---|---|---|---|
| IEC61215 | 85°C / 85±5% (20h) | -40°C (0.5~4h) | High Temp. Rise & Fall (100°C/h) Low Temp. Rise & Fall (200°C/h) |
