Chinese PV Industry Brief: CNMIA reports flat solar cell, module prices
The China Nonferrous Metals Industry Association (CNMIA) says wafer, cell and module prices remain stable, while industry operating rates are edging lower across leading and integrated manufacturers.
Longi builds 27.25%-efficient back-contact solar cells with high-resistivity wafers
High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.
Hinen launches 15 kW three-phase hybrid inverter
The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimized self-consumption.
The impact of azimuth angles on PV power production in Saudi Arabia
Researchers in Saudi Arabia conducted a year-long simulation of fixed-tilt PV panels at different azimuth angles, finding that south-facing panels (180°) maximize energy production, while up to 45° eastward shifts cause minimal losses.
Polysilicon transactions remain subdued amid buyer hesitancy
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Fraunhofer ISE, PTB report just 0.15% uncertainty in PV module yield measurements
An interlaboratory comparison between the CalLab PV Modules of Fraunhofer Institute for Solar Energy Systems ISE and Physikalisch-Technische Bundesanstalt finds the two organizations deviate by less than 0.15% when measuring the performance of photovoltaic modules. The Fraunhofer team says this is one of the most important indications as to whether their analysis is on the right track.
Mibet launches universal metal roof mounting system
The Chinese supplier said the new product uses high-strength AL6005-T5 aluminum alloy and SUS304 stainless steel. It can be adjusted to a tilt angle of 0-15°.
IEC-based technical specifications needed for second-life PV module market
The latest report from the International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.
SALD launches large area sheet-to-sheet tool for perovskite solar pilot lines
The Dutch spatial atomic layer deposition equipment manufacturer has launched a new sheet-to-sheet tool for pilot production of large area perovskite solar devices on glass substrates.
UV testing, solar cell factory inspection now mandatory for Munich Re’s PV warranty insurance
The world’s largest reinsurer has recently introduced stricter requirements for PV warranty insurance to further de-risk insured PV parks and set a higher benchmark for industry wide reliability and production quality.
