Bifacial modules

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.

Results from PID stress tests can be misleading when bifacial PV modules are PID-stressed from just one side using the foil method in IEC TS 62804, according to a new study by Belgian researchers. An unintended electric field arises between the non-stressed side of the cell and the grounded interior of the climate chamber, which may have the undesired effect of causing additional PID stress.

Scientists in Morocco have designed a new bifacial module with a cooling system, based on bifacial parabolic solar cells that are connected to each other via tubes for panel cooling. They are now patenting the tech, but have yet to manufacture an initial prototype.

A global assessment of bifacial testing methods conducted in Singapore has endorsed the approach taken by France’s Institut National de l’Énergie Solaire.
