Modules & Upstream Manufacturing

Scientists have placed four PV panels in a 21-meter wind tunnel and run different tests regarding tilt angles, mounting height, spacing, and incoming flow direction. They found that when the spacing between panels exceeds twice the panel height, the mutual influence on dust deposition becomes negligible.

A group of scientists has developed an open-source dataset comprising three years’ worth of data from Hong Kong’s largest behind-the-meter rooftop solar power project. Power generation was collected at 5-minute intervals, and meteorological data at 1-minute.

Sunairio has launched software that features high-resolution historical climate data and high-resolution future climate models to provide insights into site-specific risks. It recently raised venture capital to expand into new markets for its solar and wind portfolio-oriented software.

As the global solar energy industry grows, so does the need for accurate monitoring of performance and financial viability. The latest report by IEA PVPS Task 13, “Best Practice Guidelines for the Use of Economic and Technical KPIs,” provides a comprehensive framework to address this issue. This article explores the importance, methodologies, and applications of Key Performance Indicators (KPIs), with a focus on their role in optimizing PV systems.

Scientists in Iran have designed a CPV system that integrates a paraffin-based nanomaterials cooling system with fin, as well as thermoelectric generators that turns wast heat into electricity. Simulated results demonstrated that, with the cooling system in place, the PV efficiency improves by approximately 16.46% in clean conditions.

Researchers have constructed a miniature PV field at an altitude of 2,500 m in Switzerland. They tested it across 80 different positioning settings and compared the results to the guidelines provided by the Swiss government for a subsidy program. They found that the simulated yield was underestimated by up to 16%.

Researchers in China have investigated the impact of phosphorus diffusion gettering on industrial silicon heterojunction solar cell and have found that, with an optimized gas flow, higher efficiencies can be achieved.

Laser Tools Co. updated its laser-guided toolkits for ground-mounted solar installations.

Huasun has launched its 720 W Kunlun G12 dual-glass bifacial solar panels for vertical PV projects at the World Future Economic Summit in Abu Dhabi. The panels feature a 23.2% power conversion efficiency and enhanced mechanical stress resistance with a steel alloy frame.

The proposed bilayer is used as a hole contact material that ensures an improved adhesive contact with the perovskite film. It consists of a phosphonic acid self-assembled monolayer with an upper layer made of an organic compound known as triphenylamine.
