The world’s sunniest PV testing field

French energy giant Engie recently commissioned a solar module testing facility in Chile’s Atacama Desert, a region which has the world’s highest solar radiation. Thore Müller – head of bifacial PV R&D and solar services at Engie Laborelec, talked to pv magazine about the advantages of testing panels, inverters and cleaning systems in hot, arid environments.

A closer look at Jinko’s 565 W to 585 W panel

The module – which measures 2,411 mm × 1,134 mm × 35 mm, weighs 31.1 kg and features 156 p-type monocrystalline cells – is available in five versions with power outputs of 565 W to 585 W and efficiencies of 20.6% to 21.4%. Jinko says the Pro Tiger series will become the company’s main revenue stream in 2022, surpassing the Tiger 475 W panel.

European consortium bid to bring 25.4%-efficient heterojunction-IBC solar cell into mass production

The EU-funded Nextbase project aims to manufacture heterojunction, interdigitated back-contact solar modules for less than €0.275/W. Solar panels featuring the Nextbase cell tech are expected to have a conversion efficiency of 23.2%, according to the European Commission.

Earth’s magnetic field affecting PV panel performance

Researchers in Kenya say the geomagnetic field could reduce solar panel conversion efficiency 0.21% between the equator and a 50-degree latitude. Their analysis showed the complex magnetic field can determine increases in module fill factor and falls in maximum power.

Single-axis bifacial PV offers lowest LCOE in vast majority of world’s land area

Researchers from the Solar Energy Research Institute of Singapore have concluded that utility-scale PV projects relying on bifacial panels and single-axis trackers deliver the lowest levelized cost of energy in most of the world. They found that the combination of bifacial products with dual-axis trackers is still too expensive, despite the higher yield. The second-lowest LCOE is offered by monofacial single-axis tracker plants.

A 17.5%-efficient PV tile for building-integrated solar rooftops

Roof Tiles Technology of the U.K. has developed a solar tile with a claimed efficiency of 17.5% and power output of 175 W per square meter. The company’s founder, Antonio Lanzoni, said a PV system featuring the product would cost 25% to 30% more than a standard solar rooftop.

Used EV batteries for large-scale solar energy storage

MIT scientists have suggested that used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid-scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.
