Bifacial modules

The company’s new ASTRO N7 Pro PV modules achieve 2% higher cumulative energy yield over the project lifecycle compared to conventional previous-generation modules, according to Astronergy Head of Global Product Management Baohua He.

Terrasmart has designed and manufactured a racking system for a 2.8 MW solar carport project at Ohio’s Cincinnati Zoo and Botanical Gardens. The site’s owners claim it is the largest publicly accessible solar array in the United States, providing shade for up to 800 vehicles.

Using a surrogate model for finite element analysis, the scientists have designed an aluminum frame for bifacial modules that reportedly minimizes deflection and production costs, without adding too much weight. Deflection can lead to cracking or delamination of ribbons inside the module, resulting in an increase number of damaged cells.

Scientists in Palestine say that controlled tests show that bifacial solar panels produce 6.81% more electricity than monofacial PV modules.

Scientists in India utilized solar geometry to create a novel energy estimation model that reportedly accurately predicts both the front and back irradiance of bifacial PV modules. The model achieved correlation coefficients of 1.04 and 1.40 for the front and rear side, respectively.

Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.

While solar modules and inverters can greatly influence the output of a planned solar project, it is important not to overlook how to select and design cabling systems for your solar plant – for safety as well as generation considerations. Ye Qilin, a senior system engineer at Huawei’s FusionSolar smart PV and energy storage business, runs us through some dos and don’ts.

The U.S. president issued a proclamation on Oct. 10 that cites the impact of imported bifacial panels on U.S. solar manufacturing, while also raising the scheduled fourth-year tariff rate from 15% to 18%.

Jolywood is one of the few PV manufacturers, who has placed its bet on TOPCon technology. Instead of focusing on the simplicity of the production process, Jolywood believes the conversion rate is more critical. With years of efforts, the company has established its leading position among TOPCon players. During the SNEC 2020 in Shanghai, pv magazine had the opportunity to interview Liu Zhifeng, Vice General Manager of Jolywood, and listened to his views on some hot topics, especially the cell tech route.

Researchers have announced a new technique that is a modified version of the isotropic diffuse model.
