Outdoor system for the optimized bifacial Use
Monofacial photovoltaic modules, which receive solar radiation only from the front of the module, have long been the prevailing industry standard. In recent years, however, the focus has increasingly been on bifacial PV modules, which offer many new possibilities and advantages to their installers. The biggest difference between mono-facial and bifacial modules in practice is that bifacial modules are able to collect reflected and diffuse solar radiation from the back of the module as well.
Depending on many factors, such as installation height, the reflectivity (albedo) of the subsurface, shading of adjacent rows, and the amount of diffuse radiation, the additional bifacial yield can be as high as 30%. Since 2014, bifacial installations have increased rapidly, and there appears to be no end in sight. Some estimates suggest an increase of up to 60% in the near future, which means that bifacial solar systems could become the new industry standard.
The Sigma II Bifacial System from Mounting Systems
At Mounting Systems, we have optimized our substructures accordingly to respond to the growing demand for bifacial systems. Our excellent bipartite Sigma II Bifacial Ground-mounted system is specially designed to avoid shading on the back of the modules. The fixed mounting system is highly adaptable, allowing for a fully customized design. The ease of installation together with the corrosion resistance make the system a wise investment and guarantees a long life.
In addition, the system allows for multiple module configurations. Depending on the specific requirements of a project, different foundations such as driven piles, grounding bolts or foot plates can be used. Like all our other mounting systems, the Sigma II Bifacial is designed and produced under certified sustainability standards, and the components are easy to disassemble and recycle. In this way, the ecological footprint can be minimized.
Mounting Systems - More than a system. It's a brand.
