Trina Solar, a firm that claims to have delivered over 40 GW of modules worldwide, has just launched its latest offerings for the global market. These include the ‘Duomax V’ bifacial double-glass panel and ‘Tallmax V’ (backsheet) series panel. Based on the 210mm x 210mm large-size silicon wafer and monocrystalline PERC cell, the new panels enable high power output of more than 500Wp and module efficiency up to 21 percent.The new offerings are targeted squarely at utility scale plants. The from expects to start taking orders from Q2, with production starting in Q3.
The new panels seek to fill gaps in the firms portfolio, as P-type multicrystalline and monocrystalline panels considered ‘standard’ (156mm x 156mm) till now, become onsolete. The new shift to larger wafer sizes that require half-cut cells or multi-cut cells with multi busbar (MBB) technologies or stacking and shingling interconnect technologies to limit sheet resistance and provide high cell and panel output safely is taking over key markets. India of course is well behind the curve yet, and continues to offer a large market for the older technology products.
Trina claims that the 500W Duomax V can reduce the balance-of-system (BOS) cost by 6 to 8% and reduce the levelized cost of energy (LCOE) by 3 to 4%. This is supported by the panels offering a combination of multi-busbar technology that integrates advanced three-piece, non-destructive cutting and high-density packaging technologies. This further reduces the resistance loss and significantly improves the anti-cracking, anti-hot spot performance of the modules while maximizing space utilization.
The Duomax V bifacial double-glass panel has passed TUV Rheinland photovoltaic module IEC tests and been granted the IEC 61215 and IEC 61730 PV panel performance standards certificates. The DuoMax V bifacial double glass series panel has 150, 210mm cells (1/3 cut: 3 x 5 x 10) configuration. Its dimensions are 2187mm x 1102mm x 35mm (86.10 x 43.39 x 1.38 inches). Weight: 31.1kg (66.4lb).
The Tallmax V has 150 210mm cells (1/3 cut: 3 x 5 x 10) configuration. Module dimensions: 2176mm x 1098mm x 35mm (85.67 x 43.23 x 1.38 inches)
