The HYPERSOL VSMDH.66 series represents Vikram Solar's next-generation photovoltaic modules built on the rectangular G12R wafer format. Instead of conventional square cells, the manufacturer relies on N-Type TOPCon cells in a half-cut configuration, which reduces resistive losses and improves module performance under partial shading - a common issue on roofs with complex geometry. The series' defining feature, however, is its bifacial design, allowing the module to capture additional energy from light reflected off the surrounding surface, making it particularly well suited for ground-mount installations, light-colored roofs, and elevated racking systems. The G12R format combined with a higher cell count delivers strong unit power output while keeping module dimensions close to standard panels, simplifying system design and lowering BoS costs. The HYPERSOL VSMDH.66 series targets both commercial investors and utility-scale developers seeking high energy yield and a lower LCOE over the module's operating lifetime. The panels come with a 30-year product warranty and hold IEC, UL, and BIS certifications, confirming their reliability across international markets.

Common questions

6 answered
Are Vikram Solar HYPERSOL VSMDH.66 panels suitable for ground-mounted installations?
Yes, this is one of the series' primary use cases. The bifacial design allows the module to capture light reflected off the ground surface, making HYPERSOL VSMDH.66 panels particularly well suited to solar farms, high-albedo surfaces (gravel, white roofing), and elevated mounting structures where the rear side has clear exposure to reflected sunlight.
What warranty comes with Vikram Solar HYPERSOL VSMDH.66 panels?
The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty, standard for modern N-Type TOPCon modules. The panels hold IEC, UL, and BIS certifications, confirming compliance with international quality and safety standards - relevant for both commercial investments and utility-scale installations.
What is TOPCon cell technology used in HYPERSOL VSMDH.66, and how does it differ from PERC?
TOPCon (Tunnel Oxide Passivated Contact) is an N-Type cell technology that reduces recombination losses through an additional passivating layer on the cell's rear side. Compared to older PERC cells, it delivers higher efficiency, lower annual degradation, and better performance at high temperatures and low irradiance, resulting in higher annual energy yield.
Will HYPERSOL VSMDH.66 panels perform well on a complex roof with partial shading?
Yes, thanks to half-cut cell technology, each cell is split in two, reducing resistive losses and limiting how much a shaded section of the panel affects the entire module's output. This design lowers the impact of shading from chimneys, antennas, or nearby buildings on total system energy production.
How much extra energy does the bifacial design of the HYPERSOL VSMDH.66 generate?
The bifacial energy gain depends on installation conditions - ground albedo, mounting height, and tilt angle. In practice, with a high-albedo surface and adequate mounting height, this type of module can achieve an additional energy gain of roughly ten to twenty percent compared to a monofacial module of the same rated power, meaningfully lowering LCOE over the system's lifetime.
Is Vikram Solar a Tier 1 manufacturer, and where are HYPERSOL VSMDH.66 panels produced?
Yes, Vikram Solar is classified as a Tier 1 manufacturer, headquartered in India. Tier 1 status reflects financial stability and a well-documented, multi-year track record of large-scale module supply, which matters when assessing project bankability and long-term availability of warranty service.
