Global solar and storage enterprise Canadian Solar has earned a High Achievement rating from third-party lab RETC (Renewable Energy Test Center, LLC) for its CS7N-TB-AG module. The company said the module excelled across multiple reliability tests, including LID, LeTID, TC, DH, SDML, and PID. In particular, LID and LeTID degradation were both found to be under 0.5%, while DH and PID degradation remained below 1.0% – significantly outperforming RETC’s 2.0% threshold. Canadian Solar says these results highlight its module’s outstanding reliability and durability under extreme environmental conditions.
Earlier this month, Canadian Solar announced its plans to expand its solar module production capacity at its Yancheng facility from 6 GW to 11.2 GW (see China Solar PV News Snippets).
Perovskite manufacturer SolaEon Technology has announced that its all-perovskite tandem solar cell achieved a certified conversion efficiency of 31.38%, with a stabilized MPPT efficiency of 30.7%, which the company states both setting new global records for this cell type. SolaEon noted that its tandem cell efficiency has risen from 29.34% in 2024 to 31.38%.
Last month, SolaEon announced 31.27% conversion efficiency for its all-perovskite tandem solar cells (see China Solar PV News Snippets).
Global semiconductor display giant BOE disclosed progress in its perovskite business during its 2024 earnings briefing. Key milestones include:
Achieving 26.3% efficiency on 25 × 25 mm lab-scale cells (March 2025)
Reaching 20.79% on 300 × 300 mm cells via a pilot line launched in May 2024;
Hitting 17.52% efficiency on 1.2 × 2.4 m modules from a semi-industrial line launched in Sept. 2024, setting a record for the largest-area, highest-efficiency reported perovskite module to date.
In March, Chinese smartphone manufacturer Infinix released the world’s first solar-charging smartphone using BOE’s advanced perovskite technology. BOE disclosed that this product is still in R&D at present.
The management of BOE stated its perovskite technology is now among the industry’s leading tier, with plans to finalize scalable manufacturing solutions after completing technical validation across its lab and pilot lines.
Microinverter manufacturer APsystems has announced that it has supplied microinverters for a 25 MW distributed solar PV power plant in Nanjing, now grid-connected and operational. Installed on over 150,000 m² of rooftop space at the Nanjing International Expo Center, the system includes 6,442 sets of APsystems’ QT2D microinverters and over 40,000 high-efficiency solar modules. Operating under a self-consumption plus grid-export model, the project is expected to generate 24.8 million kWh annually. It is reportedly the largest single-site distributed PV project in China to utilize microinverters.
Wind power converter and solar PV inverter manufacturer Hopewind has reported total revenues of RMB 3.73 billion ($511.7 million) for FY2024, roughly flat year-over-year (YoY). The company’s net profit for the period fell 12.28% YoY to RMB 440.58 million ($60.45 million). Its PV inverter shipments for the period were down 50.58% YoY to 61,600, with the domestic market accounting for over 90% of revenue in this segment, which totaled RMB 922.97 million ($126.6 million). The company produced 8.87 GW of inverters in 2024, with a production-to-sales ratio of 98.72% and a capacity utilization rate of 68.26%.
