Waaree Energies has unveiled a new solar panel based on back contact (BC) and tunnel oxide passivated contact (TOPCon) cell technology.

The double-glazed panel uses G12R format cells and has an energy conversion efficiency of 23.88%.

It is part of the Tejomay series, which includes double-glazed rear contact modules ranging from 635 W to 665 W with efficiencies between 23.51% and 24.62%.

Built using 132 n-type half-cut cells, the module features 2mm semi-tempered glass on both the front (HTAR) and back, along with an anodized aluminum alloy frame. It offers a bifaciality of approximately 75%.

The module measures 2,382 mm x 1,134 mm x 35 mm and weighs 34 kg. It is backed by a 12-year product warranty and a 30-year performance warranty.

In India, Waaree Energies operates production facilities with a total installed capacity of 13.3 GW for PV modules, including 1.3 GW from Indosolar and 1.4 GW for PERC solar cells.
