SEG Solar and Astronergy supplied new tunnel oxide passivated contact (TOPCon) modules, alongside an n-type back-contact sample from Aiko, for installation in the first week of March 2025. To add these new products to the comparison table in these results, we removed the production data from before March 7. Due to downtime for system upgrades, we also did not capture data for three days in March and therefore had to remove those days from the total energy yield calculation. Finally, three products using 210 mm square cells were removed from the data, as we identified anomalies in the production figures caused by the maximum power point tracking algorithm. The data from those products will be reported again as soon as the issues are resolved.

At the end of February 2025, three new samples - two tunnel oxide passivated contact (TOPCon) samples from SEG Solar and Astronergy and our first n-type back contact sample from Aiko – arrived in Yinchuan and were installed at the beginning of March. The outdoor data for these will be published next month.

The new outdoor test field in Yinchuan, China, began operations on Dec. 9, 2024. Due to system modifications, the data of Dec. 23 were removed. In January, we were close to getting a full month’s worth of data, but unfortunately, due to an operational error, we lost data for several modules after Jan. 24. At present, this problem has been solved and we expect that a full month’s data will be presented in the next issue of pv magazine.

After more than seven years, pv magazine test is entering a new phase. Significant changes are on the horizon as we update and overhaul the program. George Touloupas, Vice President, ESG and New Services at Clean Energy Associates (CEA), and Huatian Xu, Director of Technology and Quality at CEA, introduce the new “pv magazine test 2.0” setup to assess PV modules in the lab and outdoors. 

George Touloupas, senior director of technology and quality at Clean Energy Associates, presents the November and December 2024 results from the pv magazine test site in Xi’an, China. These are the final results from this installation, as we prepare to launch a brand new pv magazine test program for 2025 – the full details will appear in next month’s edition.
