Leading PV inverter manufacturer Huawei discusses recent technical developments in better understanding bifacial module PV power plants using three recent case studies.
The highly efficient PV module technology that is widely used in the industry is a bifacial module. These efficient PV modules need to be used with devices such as inverters to maximize value. Recently, many inverters and solutions that match bifacial modules have appeared in the industry. Which solution is the best match for bifacial modules? Based on a large amount of experimental data, this article describes the solution needed for bifacial modules.
We have tested standard and bifacial modules with the same structure for a long time. As shown in the figure, the energy yield gain from the rear of the bifacial module varies depending on the scenario, and the energy yield increases by 5%–39%. In addition, the bifacial module can further increase the energy yield by 2%–6% based on its excellent performance of good response to low light and low power loss under the working temperature.
Generally, the energy yield gain of a bifacial module compared to a standard PV module is about 7%–45% in the scenarios listed in Figure 1-2 (above).
