Talesun’s latest mono-PERC module series offers 570/590Wp performance for utility scale projects April 14, 2021 Email The Talesun Bistar monofacial modules (3.2mm AR Coating Tempered Front Glass) measure 2,465mm x 1,134mm x 35mm and weigh 31.5kg in the 156 (6 x 26) half-cut monocrystalline cell configuration. Talesun Solar has launched a next-generation series of large-area high-efficiency PERC (Passivated Emitter Rear Cell) modules for utility-scale PV power plants. Available in both monofacial ‘Bistar’ and bifacial ‘Bipro’ formats, using 182mm half-cut cells in 144 and 156 cell configurations, they provide up to 590Wp performance with module efficiencies up to 21.2%. Problem The PV industry is rapidly transitioning to larger format modules, with power ratings approaching 600Wp. This is being driven by the need to continue reducing the LCOE (Levelized Cost of Electricity) through lowering the cost of installation and BOM (Bill of Material) component count, while accelerating the return on investment of utility scale projects. Finding and deploying the correct PERC-based wafer/cell/module format size and innovations at the cell and module level for a given project and understanding its impact and compatibility with PV inverters and tracker systems, especially with bifacial modules, is required.
