bifacial gains

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%.

The debate continues over whether super-sized, high-power solar modules are a good thing for the industry and they appear to be here to stay. Vicente Parra and James Whittemore, from Enertis Applus+, consider the pitfalls to avoid when designing high-power solar projects.

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.

Bifacial solar module technology will find beneficial application in a significant number of solar energy power plants, according to a technical assessment conducted by ArcVera Renewables. While advertised 25% or greater gains in energy yield are unlikely for most projects, typical project energy production gains are 3-10%. Analysis finds that many projects under the scrutiny of informed technical due diligence, proper measurement and site design, will reap meaningful net present value. Although financing institutions have recently not awarded significant debt financing value to bifacial projects, full credit for bifacial benefits are expected to accrue rapidly, as experience and market penetration increases.
