Succeeded in 8 Extreme Tests: How Does Yingli Solar's Intelligent Manufacturing Take the World by Surprise?
Let's take a close look.
Generally, PVEL performs 8 extreme tests on the subject modules in accordance with standards stricter than those of IEC. For example, the standard for the thermal cycling testing is three times stricter than that of IEC. Specifically, modules should be subject to eight PVEL tests as follows:
1. TC: Thermal cycling test, according to the standard three times stricter than that of IEC.
2. DH: Damp heat test, according to the standard twice stricter than that of IEC.
3. MSS: Mechanical stress sequence, which will test the quality of modules under dynamic and static loads.
4. Hail: Hail stress sequence. IEC generally tests the products with hails at a diameter of 25mm, but PVEL uses hails at a diameter of 50mm. Under such harsh testing conditions, Yingli Solar is "one of the few manufacturers that have passed this test", PVEL was quoted as saying.
5. PID: 192 hours for the standard of PVEL, stricter than the standard (96 hours) of IEC.
6. LETID: Light- and elevated temperature-induced degradation, according to the standard stricter than that of IEC.
7. LID: Light-induced degradation, according to the standard stricter than that of IEC.
All of the above 7 tests are intended to test the reliability of the modules under extreme conditions, and only those with efficiency attenuation not greater than 2% are deemed as winners. Yingli Solar's modules passed the above 7 tests successfully with an attenuation rate much lower than 2% in each of them, or even only 0.04% in a test.
That is not the end of the story.
Here comes the most marvelous part.
PVEL conducts a PAN test on the modules, where it simulates the power generation at two typical locations through PVSYST, and only BOMs in the top 25 percentile will enter the white list.
Yingli Solar's modules not only passed those 7 rigorous tests, but also ranked in the top 25 percentile among all tested modules in terms of power generation.
How difficult will it be for a manufacturer to succeed in all these eight tests? Data showed that
