A comparison between monofacial and bifacial PV systems in Ghana showed how changes in system parameters can affect the bifacial gains. The researchers found that changing the albedo of a land-based system can increase the bifacial gain from 5.25% to 14.5%.

P.G. Solar Greener says that its new panels have a thermal capacity of 1,280 Wh. They can reportedly achieve an overall dual electrical efficiency of 26%, due to an embedded cooling technique.

Scientists in India have developed a novel way to predict soiling accumulation on bifacial modules. Their approach considers dust deposition, rebound, and resuspension phenomena.

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.

Germany-based Solmax has developed a reflective membrane made of polyethylene resins and coated with a thin white polyethylene layer that reflects ultraviolet (UV) rays. The company claims the membrane can increase the energy yield of a bifacial PV project by between 5% and 20%, depending on the plant configuration.

US scientists recently put different bifacial solar cells and modules through a series of tests at elevated temperature, humidity, voltage and mechanical stress levels. The tests revealed a range of light-induced and potential-induced degradation mechanisms that modules will likely suffer in the field.

The Monroe County Water Authority recently flipped the switch on a 5 MW ground-mounted solar array in Penfield, New York.

Scientists in the Netherlands have developed a model to forecast the energy yield of a PV system. It is able to take into account factors such as partial shading and multiple module orientations. Tested against a reference cell and pyranometer, the model showed less than 5% error, and the scientists claim their approach is up to three orders of magnitude faster than more common approaches using complex ray tracing.

Some 1.5 million bifacial panels make up the power plant in Ad-Dhahirah governorate which was constructed in just 13 months by ACWA Power, the Gulf Investment Corporation and Kuwaiti developer Alternative Energy Projects Co.
