I found this article demonstrating PV performance
Post# of 22456
We find three key takeaways from the Scorecard’s test results.
• Overall, many module vendors performed well across all tests. For example, 8 manufacturers degraded less than 3% after 4 times the IEC duration in Thermal Cycling (the IEC pass/fail criteria for 200 cycles is 5% degradation).
• Two manufacturers performed in the top group on every test: Kyocera and Phono Solar.
• Roughly 55 – 60% of top group modules were manufactured in China. This is roughly equivalent to the ratio of Chinese module participation in the full PV Module Reliability Scorecard. This demonstrates that manufacturing location is not a good proxy for reliability.
