• It analyzes and validates the effect of different materials and structures on the performance of solar panels.

4. Environmental Adaptability Evaluation:

• Testing solar panels' performance under high humidity, high temperature, and low-temperature conditions helps assess their suitability for different climates (e.g., tropical, cold regions, etc.).

1. Temperature and Humidity Testing:

• By setting various temperature and humidity conditions, the chamber conducts single or multiple environmental tests, observing the solar panel’s performance.

• Temperature and humidity changes are typically conducted in a pre-set program, which may involve continuous constant testing or cyclic variations.

2. Accelerated Aging Testing:

• Using high-temperature and high-humidity environments, this test accelerates the aging process of solar panels to assess their durability during actual long-term use.

• Testing usually lasts from several weeks to several months, predicting the panels' service life.

3. Damp Heat Cycling Test:

• By continually changing humidity and temperature, this test simulates the humid conditions solar panels may face, such as during rainy seasons or in high-humidity areas.

• It evaluates the effects of corrosion, material expansion, and thermal stress.

4. High-Low Temperature Cycling Test:

• By rapidly alternating between high and low-temperature environments, this test assesses solar panels' resistance to sudden temperature changes, checking for potential cracks, expansion, or other damage.

5. Electrical Performance Testing:

• The chamber tests the electrical performance of solar panels under different temperature and humidity conditions, observing their operational status under extreme environments.

• Key performance parameters such as conversion efficiency, short-circuit current, and open-circuit voltage are tested to evaluate their performance in varying conditions.

6. Material and Structural Observation:

• The external appearance of solar panels is observed during the testing process, including corrosion, cracks, oxidation, and other phenomena.

• Microscopic analysis and X-ray inspection can be used to analyze the material structure, assessing its durability and anti-aging capabilities.
