The Vikram Solar PARADEA (VSMDH.66.AAA.05) series are bifacial glass-glass modules designed to effectively increase energy yield, even when conditions on the roof or ground are not ideal. By operating from both sides of the module, they better utilize reflected light, resulting in higher yields in locations with reflective surfaces or in installations on elevated structures. Key features include:

* Bifacial glass-glass technology, which enhances durability in harsh environments and reduces the risk of microcracks and deformations. * Multi busbar (MBB) technology, which improves current collection and resistance to micro-damage. * Half-cut monocrystalline solar cells, which help reduce losses and improve stability, while connection box solutions support better performance under partial shading.

This makes it a good choice for PV farms, large commercial and industrial installations, and projects where lower energy costs and reduced operating losses over the long term are priorities.

Common questions

6 answered
Is the Vikram Solar PARADEA VSMDH.66.AAA.05 panel still available for purchase?
No, this specific version of the PARADEA series (VSMDH.66.AAA.05) has been discontinued. Vikram Solar continues to develop the PARADEA line under newer model codes, so availability of this exact SKU is now limited to remaining distributor stock. Buyers should confirm current inventory with the seller and compare specs against the manufacturer's current lineup.
How much extra energy does bifacial technology actually add compared to standard panels in the PARADEA series?
The glass-glass design of PARADEA panels captures light reflected off the ground surface through the rear side of the module. The gain depends on ground albedo and mounting height, but in typical ground-mount installations over light-colored surfaces or gravel, this usually adds several to over ten percent more annual energy yield compared to a monofacial panel of the same rated power.
What warranty comes with the PARADEA VSMDH.66.AAA.05 modules and what does it cover?
Vikram Solar provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power performance warranty guaranteeing limited output degradation over time. This is standard for Tier 1 manufacturers and gives investors confidence in long-term returns from the installation.
Do half-cut cell PARADEA panels handle partial shading better?
Yes, the monocrystalline half-cut cells combined with multi busbar (MBB) technology divide the module into smaller electrical sections. This means partial shading from leaves or a chimney causes a smaller drop in overall panel output compared to conventional full-cell modules.
What installations are the 680 Wp PARADEA panels best suited for?
Thanks to their high per-unit power output of up to 680 Wp and bifacial glass-glass construction, the PARADEA series is best suited for large-scale PV farms and commercial and industrial (C&I) installations, where a lower levelized cost of energy and reduced long-term operational losses matter most.
How does glass-glass construction differ from standard backsheet panels, and is it worth the extra cost?
In glass-glass panels, the cells are laminated between two glass sheets instead of glass and a polymer backsheet. This increases module rigidity, reduces the risk of micro-cracks and warping, and improves resistance to moisture and degradation in harsh climates. The added cost typically pays off through longer service life and bifacial energy gain.
