Canadian Solar Inc. has shipped accumulatively 2.6 GW of high efficiency anti-LeTID PERC solar modules worldwide as of December 31st, 2018. »This represents a significant milestone in Canadian Solar's continuous efforts in developing and delivering high efficiency and high quality solar modules,« says the company.
Solar modules with Passivated Emitter and Rear Cell (PERC) technology can significantly improve the module efficiency compared to standard modules with aluminum back surface field (Al BSF) cells, which significantly reduces solar system's Balance of System (BOS) costs. In addition, PERC modules exhibit lower temperature coefficient and lower operation temperature over Al BSF modules, therefore further improving energy yield of solar systems, resulting in lower levelized cost of electricity (LCOE) and higher return on investment (ROI).
LeTID, or Light and elevated Temperature Induced Degradation, in PERC modules is a phenomenon exhibited in both lab tests and field operations. This degradation effect usually happens when module temperature is higher than 50 degrees Celsius and the magnitude of such degradation can reach up to 10 percent for both multicrystalline and monocrystalline PERC modules, says Canadian Solar.
»Going into 2019, we will soon convert all of our cell capacities into PERC technology. The successful mitigation of LeTID, combined with our gigawatt-scale high efficiency module technologies such as Ku, BiKu, HiKu, HiDM and BiHiKu, further solidifies Canadian Solar's leadership in solar technology and products,« commented Shawn Qu, Chairman and CEO of Canadian Solar.
