India’s Vikram Solar has launched its Paradea line of mono PERC bifacial glass-to-glass PV modules.
The multi-busbar panels provide power outputs ranging from 635 W to 660 W, with efficiencies between 20.38% and 21.18%. Bifacial gain is up to 25% with the dual-glass modules, leading to 825 W of overall power output.
The modules feature 132 half-cells. They measure 2,391 mm x 1,303 mm x 35 mm and weigh 39.3 kg.
Under standard test conditions, the open-circuit voltage is between 45.8 V and 46.3 V. The short-circuit current ranges from 17.76 A to 18.17 A.
The modules are designed for large-scale utility systems, commercial and industrial systems, and residential rooftop systems.

Indian vikaram Solar manufacturers all’the best
Absolutely ridiculous. I’m a panel installer. The panel dimensions now are already to big to handle comfortably, never mind to fit a decent quantity on most domestic rooftops, So what do manufacturers do??? Make bigger one that weigh over twice as much putting more load on roof structures and not even considering how these 8ft sails are to be handled safely by workers. Increasing efficiency is key, not the physical dimensions. All this will do is increase labour prices for installations driving demand for solar right down as we will need cranes to manage them without crippling our backs. Good luck with that because I definitely won’t buy nor offer a product that size for domestic nor commercial.
I believe there is a better way to increase efficiency without increasing the weight of the panels which should be explored. Increasing the dimension of a panel is similar to adding more panels of the same dimension and capacity to an existing array or string as the case may be.
