Designed by Chinese provider Mibet, the mounting structure can be used for different crop types. The system offers a tilt angle of up to 30 degrees and can host either framed or frameless solar modules.

Spanish company Axial Structural is introducing a new type of tracker for agrivoltaic installations. The product can be adapted to various ground conditions and gradients, with programmable to optimise light and shade for different crops in different climates.

Vietnamese manufacturer Irex has announced a new glass-glass solar panel with a power output of 265 W and a power conversion efficiency of 18.1%.

Vattenfall is leading a Dutch consortium in a research project to assess whether agrivoltaics is also compatible with strip cropping. The company’s head of Solar Development NL, Annemarie Schouten, spoke with pv magazine about the first 0.7 MW pilot project under development in the northern Dutch province of Flevoland.

Developed by Chinese researchers, the novel design methodology consists of utilising metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. According to its creators, it ensures a farmer’s average income increases by 5.14 times, including the solar power generation business. A system built with this approach should cost around €715 (AU$1145) per kW installed.

The PV mounting system was developed by Germany-based Goldbeck and will initially be available in the Netherlands from 2022. The company will test the new technology in a 45 MW PV project.

US expert in environmental and energy policy Alexis Pascaris spoke with pv magazine about opportunities and barriers associated with agrivoltaics. Agrivoltaics are a very practical and advantageous alternative to large-scale solar, specifically in places where there are land-use constraints or needs for rural economic development, she explains. Differences in costs related to ground-mounted solar can typically be attributed to the raised racking systems or additional fencing, but these upfront investments in specialised hardware are eventually recovered as agrivoltaic systems produce dual-revenue streams.

A U.S. scientist has developed a computational framework that assesses how well a hypothetical agrivoltaic project would perform in achieving desired outcomes such as the volume of PV electricity produced, and energy-to-agriculture. The method considers the high-frequency decomposition of solar irradiance into multiple rays and analyzes how these rays are propagated forward in time, to assess multiple reflections and absorption for various system configurations. It also takes into account panel inclination, panel refractive indices, sizes, shapes, heights, and albedo.

Spanish tracker giant STI Norland has expanded to Australia with a new subsidiary office in Melbourne. The company is arriving on our shores with a keenness to compete with tracker suppliers who already have their foot in the door. With no solar farm too big or too small, STI Norland Australia CEO Alan Atchison sat down with pv magazine Australia to talk about how the company plans to make tracks Down Under.
