Scope and Methodology
| Step | Action | Description |
|---|---|---|
| 1 | Prepare Specimens | Clean specimens according to ASTM E2819 guidelines. |
| 2 | Create Test Environment | Set up a chamber at 85°C and maintain relative humidity at 85% RH. |
| 3 | Expose Modules | Place specimens in the chamber for 40 hours. |
| 4 | Inspect Visually | Evaluate any visible changes or defects post-exposure. |
| 5 | Measure Electrical Performance | Determine open-circuit voltage, short-circuit current, and power output. |
| 6 | Compare Results | Compare pre- and post-test measurements to assess overall performance stability. |
The process begins with thorough preparation of the specimens as per ASTM E2819 specifications. Ensuring that all surfaces are clean is crucial for accurate readings later on in the testing cycle. Once cleaned, the next step involves setting up a controlled environment within which the PV modules will be exposed to damp heat conditions.
After positioning the specimens inside the chamber at specified temperature and humidity levels, they remain there for exactly 40 hours as per ASTM E2819 requirements. During this time frame, continuous monitoring ensures adherence to set parameters while also providing valuable data points throughout the exposure period.
Upon completion of the prescribed duration, visual inspections are conducted to identify any visible signs indicative of damage or degradation due to prolonged exposure to damp heat conditions. These observations serve as an initial assessment tool before deeper analysis into functional integrity.
The final stage includes measuring key electrical parameters such as open-circuit voltage (VOC), short-circuit current (ISC), and maximum power point (MPP). Comparing these values pre-and post-test helps determine whether there has been any significant change in the module’s performance capabilities. Any deviations from expected results could suggest issues related either to material quality or design flaws.
