Dante Zeng, Product Marketing Manager at LONGi, will address the topic ‘Why BC Leads – Interpreting the BC White Paper’ on Day 1 of our annual flagship event, the TaiyangNews High-Efficiency Solar Technologies Conference.
This exclusive event brings together top industry experts to explore the latest breakthroughs driving high-efficiency solar cell and module technologies.
Across 4 days, leading voices will unpack cutting-edge PV trends – from Back Contact (xBC) and TOPCon to HJT, next-gen materials, breakthrough equipment, and smart system integration.
Each day focuses on one technology:
Day 1 – Dec 3, 2025: Back Contact (xBC)
Day 2 – Dec 4, 2025: TOPCon Solar Technology – I
Day 3 – Dec 9, 2025: TOPCon Solar Technology – II
Day 4 – Dec 10, 2025: Heterojunction Technology
Registrations are open and can be done for free here.
JA Solar has released the industry’s ‘first’ Desert-Gobi-Wasteland PV Solution White Paper, developed jointly with TÜV NORD. The document analyzes extreme desert conditions, such as high UV radiation, sandstorms, and large temperature fluctuations, and proposes a reliability testing framework that goes beyond existing standards. It also provides guidance on site selection, system design, and equipment configuration for large-scale desert PV projects.
The white paper highlights JA Solar’s DesertBlue module, designed for desert and semi-arid regions. Outdoor tests show the DesertBlue module delivering a 7.09% energy-yield gain at JA Solar’s Shanghai Fengxian site and a 4.98% gain in the Ulan Buh Desert. The reliability framework, covering UV aging, thermal cycling, sand abrasion, hotspot resistance, and high-temperature mechanical loading, was independently verified by TÜV NORD.
Recently, construction commenced on the Qinghai-Hainan Clean Energy Delivery Base, dubbed the largest Desert-Gobi-Wasteland new energy base in China (see China Solar PV News Snippets).
In unrelated news, Astronergy and JA Solar have ended lawsuits against each other and have signed a mutual cross-licensing deal for TOPCon patents (see Astronergy & JA Solar End Global TOPCon Patent Dispute).
Solar junction box manufacturer Tongling Electric has terminated construction of a new facility originally planned to produce 60 million units annually. In 2022, the company announced several expansion initiatives, including an investment of RMB 512.37 million for the 60-million-unit junction box plant and an additional RMB 302.41 million for technical upgrades and expansion of an existing PV junction box facility.
According to the latest notice, Tongling decided to discontinue the project due to declining profitability of its products and stabilizing demand from downstream customers. Construction on the facility commenced in 2023 and had reached an annual capacity of 7.5 million units/year before being halted.
Ningxia has released the results of its 2025-2026 mechanism tariff bidding. The bidding covered wind and solar PV projects scheduled for commissioning between June 1, 2025, and December 31, 2026, with a total mechanism electricity quota of 10.2 billion kWh. The preset bid cap for both technologies was RMB 0.2595/kWh with a floor of RMB 0.18/kWh.
According to the published results, all available quotas have been allocated, with 838 projects shortlisted in total. Both wind and solar projects will adopt a unified mechanism tariff of RMB 0.2595/kWh, consistent with the region’s desulfurized coal benchmark tariff.
The National Development and Reform Commission (NDRC) has issued a policy document defining the scope of industries eligible for infrastructure Real Estate Investment Trusts (REITs). The updated list aims to broaden the range of assets that can be securitized, activate existing infrastructure stock, and promote a more efficient investment cycle.
A total of 15 eligible project categories have been included, with energy infrastructure as a major segment. Covered areas include clean energy projects such as wind, solar, hydropower, natural gas power, biomass, and nuclear energy; energy storage facilities; clean, low-carbon, and flexible coal-fired power (including cogeneration); and ultra-high-voltage transmission, incremental distribution networks, microgrids, and EV charging infrastructure.
Recently, TrinaPower received approval from the Shanghai Stock Exchange for a green, carbon-neutral real estate asset-backed securities (ABS) plan aimed at supporting rural revitalization (see China Solar PV News Snippets).
