What you need to know when choose solar racking for bifacial modules?
What is bifacial module? The bifacial module, as the name implies, can generate electricity on both the front and backside of the modules. Compared with conventional single-sided modules, it can increase power generation by about 10-30%. From a technical point of view, the bifacial modules and solar trackers are a effective way to reduce the cost of electricity in the photovoltaic industry. The shading of the front of the module is often the focus of attention. However, for the bifacial module, since the back side also has the power generation capacity, the shading of the back also needs to be paid attention to, especially the shading from the solar bracket. For conventional solar brackets, the design of the main supporting beam and purlin is more concerned with strength, economy and the location of the component bolt holes (or clamps). As for the bifacial module, the solar racking system needs to be specially designed. Firstly, the main supporting beam and purlin...
