2、s a technology,bifacial has become the new standard,at least for utility-scale photovoltaic(PV)applications.With advanced TOPCon and HJT cell technologies being inherently bifacial and glass-glass becoming the mainstream,adapting to bifacial manufacturing is now more seamless than ever.At the system

3、 level,however,bifacial technology requires considerable optimization.This TaiyangNews Report on Bifacial Solar Systems discusses the system side of the technology.Several system parameters influence the bifacial benefit,and site albedo is among the top of the list.Albedo is the most critical parame

4、ter for calculating the bifacial energy yield of a PV system.It primarily varies with the surface itself,but is also affected by factors like ground vegetation,rainfall,snowfall,and soiling.Fresh snow offers the highest albedo,while water reflects poorly.On the other hand,approaches to increase albe

5、do and its uniformity with reflective materials are being evaluated.Accurate measurement of albedo is equally important.It can be measured on-site with albedometers in various configurations,or derived from satellite data.Each approach has its advantages and limitations,requiring a case-by-case sele

6、ction of the optimal method.The bifacial gain of a PV system depends strongly on its geometry,including the height(distance between the module and ground),tilt angle of the panels,and ground surface characteristics.The higher the system is set up,the greater the bifacial gain,especially with high-al
