With the globally declining trend of PV subsidies and PPA, the LCOE is also required to be reduced. With the promotion of the Eagle, Cheetah and Swan modules, high-power, high-efficiency characteristics combined with bi-facial technology have been shown to deliver higher power generation per unit area and lower BOS costs at the system end. Therefore, “high energy density” has become a significant technology direction for Jinko. Under this direction, Jinko launched its Tiger series of high-efficiency tiling ribbon modules at the All Energy Exhibition in Australia on October 23, 2019. The Tiger module adopts the advanced technologies of multi-busbar + tiling ribbon + half cut and, with the high-efficiency Jinko cell, the maximum power output of Tiger could reach 475W and efficiency 21.16%.
The Tiger series includes mono-facial and bi-facial options, the latter currently promoting transparent back sheets with DuPont’s Tedlar. While ensuring a 5% -30% backside energy gain, the light-weight feature of the transparent back sheet also effectively reduces the LCOE.
