Bifacial solar modules have attracted significant market attention over recent years. Installed capacity grew from only 97 megawatts globally in 2016 to over 5,400 megawatts in 2019. Furthermore, between 2019 and 2024, the size of the bifacial market is predicted to increase tenfold.
The driving forces behind this growth differ from region to region, but one unifying factor is the increasing affordability of bifacial modules. Additionally, the new glass plus backsheet solution enables both structure installation method and cost to be unchanged when compared with mono facial modules.
Unlike conventional glass-glass structured bifacial modules, JinkoSolar’s Swan bifacial module, with DuPont transparent backsheet, can ‘breathe out’ heat and corrosion inside the panel, thus lowering the NOCT and increasing energy yield and performance under real-world conditions. In addition to the energy generation capability over a 25 year life span, the initial BOS cost will be significantly lowered due to a reduction in weight of 20-25%, depending on the thickness of rear side glass adopted. It also helps that it is relatively easy in terms of labour and re-tooling of existing monofacial mounting methods to move to Swan bifacial modules, which provide certainty in IRR should a developer switch to bifacial.
Together, the comparable cost and ease of deployment is enabling the Swan bifacial module with transparent backsheet to compete with conventional modules and gain market share. According to the company, since June 2019, the first time the module was showcased at SNEC, nearly 2 GW of orders for Swan bifacial have been received within 6 months.
