Chamber FAQ
Solar Photovoltaic Testing Chambers
ESPEC sells temperature and humidity cycling test chambers suited for testing photovoltaic modules to ensure compliance with IEC 61215 and 61646, and other test standards.
Most popular test chamber types for solar module testing:
- Solid-construction walk-in chambers
- Platinum series temperature/humidity chambers (some modified for additional length of solar panels)
Applicable IEC 61215 & 61646 test methods:
- 10.11 Thermal Cycling Test
Cycling between 85°C and -40°C at 100°C/hour maximum - 10.12 Humidity-Freeze Test
Cycling between 85°C / 85%RH and -40°C - 10.13 Damp Heat Test
85°C/85%RH for 1000 hours
Other environmental test methods for photovoltaic solar panels
- IEC 62108 for concentrator photovoltaic assemblies (International Electrotechnical Commission)
Similar tests as IEC-61215 - JIS C-8990, C-8991, C-8917, C-8938 (Japanese Industrial Standard)
Similar tests as IEC-61215 - UL-1703 for flat-plate photovoltaic modules (Underwriter’s Laboratories)
Application Guide
ESPEC has created a specialized application guide for environmental testing of photovoltaic modules and subsystems (PDF).
This guide reviews the different ESPEC models and their application for testing solar photovoltaic products. Test methods published by JIS and IEC are summarized and matched to specific test chamber types. Test methods include: humidity freeze, thermal cycling, temperature/humidity cycling, and damp heat.
