Chint Group subsidiary Astronergy’s ASTRO N7s modules have successfully passed TÜV Rheinland’s HW4 hail resistance test. Rated as one of the highest hail resistance levels in photovoltaic (PV) module testing, HW4 is typically used to assess a module's impact resistance under extreme hail conditions. According to TÜV Rheinland’s test report, ASTRO N7s demonstrated outstanding performance by withstanding impacts from 40 mm hailstones. During the test, hailstones struck the module surface at an average speed of 27.5 m/s with an impact energy of 11.1 joules. The module remained free of cracks or damage, with stable power output. Astronergy emphasized that the ASTRO N7s modules feature a dual-glass design, providing excellent impact and compression resistance, which enabled them to pass the HW4 hail resistance test.
Powered by Astronergy ASTRO N5 modules, the 1GW (AC) Golmud Solar Plant recently completed trial operations to enter full commercial operation (see China Solar PV News Snippets).
Perovskite solar module manufacturer SolaEon Technology has announced that its all-perovskite tandem solar cells have achieved a photovoltaic conversion efficiency of 31.27% in testing, setting a new “world record” certified by the China Photovoltaic Testing Center (CPVT). This follows the company’s February milestone where its perovskite tandem cells achieved 30.58% efficiency.
Additionally, SolaEon has recently made significant advancements in the perovskite sector:
In January 2025, its unit perovskite cell (1 cm²) achieved a conversion efficiency of 26.50%.
In December 2024, its 30 cm × 40 cm large-area perovskite solar module achieved a stabilized efficiency of 21.1%.
Earlier this month, SolaEon successfully produced the first batch of perovskite solar modules from its newly commissioned 200 MW perovskite cell production line (see China Solar PV News Snippets).
Linyang ESS, the energy storage division of power plant developer, owner, and operator Linyang Energy, has obtained CE certification from TÜV SÜD for its Power Atlantic liquid-cooled energy storage battery cabin and Power Key intelligent liquid-cooled energy storage cabinet. The company says TÜV SÜD conducted months of rigorous testing based on international standards EN 62477-1 and EN 61000.
Linyang ESS highlights that during the testing, the Power Atlantic liquid-cooled energy storage battery cabin underwent full-load charge and discharge cycles under extreme conditions simulating a 50°C high-temperature environment. The system demonstrated excellent performance in thermal management, battery consistency, and system stability, verifying its safety and reliability under high-load and high-temperature conditions.
Heterojunction (HJT) solar module manufacturer Grand Sunergy plans to build a new 2 GW HJT manufacturing facility in Hami, Xinjiang. The company has submitted its environmental impact assessment report to the local ecological and environmental authority, which has now been approved. According to the report, Grand Sunergy will invest RMB 300 million ($41.32 million) through its subsidiary to construct the plant.
A Grand Sunergy subsidiary recently signed a strategic cooperation framework agreement with perovskite maker Phenosolar (see China Solar PV News Snippets).
China Nuclear Industry 24 Construction Co., Ltd. (CNNP 24), a subsidiary of China National Nuclear Corporation (CNNC), has shortlisted 10 suppliers for its 2025 solar PV module procurement. These 10 companies will be eligible to participate in the negotiations for the 190 MW module procurement, and/or bid for CNNP 24’s ongoing and planned new energy projects in Shandong Province.
The selected suppliers include Osda, LONGi, Canadian Solar, and Tongwei Solar, among others. The bidding prices ranged from RMB 0.675/W ($0.093/W) to RMB 0.721/W ($0.099/W), with an average price of RMB 0.695/W ($0.096/W).
One of the upcoming destinations for solar PV manufacturing beyond China is India, where companies are gathering support from technologists and scientists to develop an upstream value chain. The idea is not just to establish vertical integration but also to make it a resilient and sustainable one. TaiyangNews is bringing together the country’s leading solar PV players and international experts to discuss the progress of solar PV manufacturing in the Asian country in a 2-day physical event in New Delhi, India, on April 10 and 11, 2025. Omkar Jani, the CTO of Reliance Industries, will be in attendance at the conference as part of the executive panel, where he will share insights on technology improvements for profitable solar manufacturing along the value chain. Registrations for the TaiyangNews Solar Technology Conference India 2025 are open now here, where you can take a look at the list of speakers and insightful sessions planned.
