The 11th edition of the International Technology Roadmap for Photovoltaic (ITRPV) report forecasted a market share for bifacial modules less than 15% by 2020. However, the bifacial module market share exceeded above 25% in 2019 and is expected to reach 40% this year and 60% in 2021, with no indications of a market slowdown in the short term, according to PV-Tech.
The main driver of this rapid increase backs the proven increased energy yield per module area of the bifacial modules, as compared to monofactial modules. According to PV-Tech, Not long ago, the idea of bifacial modules was still considered a sort of double edge-sword versus the traditional monofacial-based PV technology. The main reasons behind this were its higher price and the somewhat limited project bankability. But due to the mentioned reason, it has become more popular in large-scale solar installations such as utility-scale.
For example, in China, the leading country in solar PV installation, more than 30% of utility-scale projects in the second half are bifacial. It is worth mentioning that bifacial modules yield higher energy from both the front and rear sides of the module. This results in an increase the energy yield per module area for them.
