The HYPERSOL G12R series from Vikram Solar is a lineup of bifacial photovoltaic modules built on N-type TOPCon technology, addressing the growing demand from investors for higher energy yields on limited roof or ground space. The panels feature half-cut cells mounted on a rectangular G12R wafer, combined with a 16 busbar layout that reduces resistive losses and improves current distribution across the module. A defining trait of the series is its high bifaciality, allowing the module to capture additional energy reflected off the ground surface, which translates into a lower levelized cost of energy (LCOE) over the system's lifetime. The manufacturer also highlights stable performance under high temperatures, making this series an attractive option for installations in warmer climates or sites exposed to intense summer irradiance. Optimized use of shipping container space helps cut logistics costs, while the materials used align with the industry's push toward recyclability and sustainability. HYPERSOL G12R is primarily aimed at utility-scale, commercial, and industrial projects where predictable, long-term performance and lower operating costs throughout the system's service life are the priority.

Common questions

6 answered
What is N-type TOPCon technology in the HYPERSOL G12R panels, and does it actually deliver higher energy yield?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces electron recombination and achieves higher efficiency than conventional P-type PERC cells. In the HYPERSOL G12R this translates into power output up to 635 Wp and module efficiency around 23.5%. It also has a lower temperature coefficient (-0.28%/°C), so the panel loses less output on hot days than typical PERC modules.
What warranty does Vikram Solar offer on the HYPERSOL G12R series?
The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. This means that after 30 years of operation, the module should still deliver the guaranteed percentage of its rated initial power as stated in the datasheet. This is standard for Tier 1 manufacturers and gives investors predictable long-term returns on the installation.
How does the bifacial HYPERSOL G12R panel differ from a standard monofacial module?
A bifacial module has active cells on both sides of the glass, allowing it to capture not only direct sunlight but also light reflected from the ground, roof, or a light-colored surface. The HYPERSOL G12R achieves a bifaciality factor of 80±5%, which in practice can add several percent to annual energy yield, especially when installed over light gravel, roofing membrane, or bright terrain. This meaningfully lowers the levelized cost of energy (LCOE) over the system's lifetime.
What type of installations is the 635 Wp HYPERSOL G12R panel best suited for?
Given its high unit power, large format (built on the G12R rectangular wafer with 132 half-cut cells), and weight of around 32 kg, the HYPERSOL G12R series targets utility-scale, commercial, and industrial projects, including large flat-roof warehouses. Needing fewer modules to reach a given system capacity reduces mounting structure, cabling, and installation labor costs.
Does the HYPERSOL G12R perform well in high summer temperatures?
Yes, this is one of the series' strengths. Thanks to N-type TOPCon technology, the power temperature coefficient is -0.28%/°C, meaning power losses from heating are smaller than in typical P-type panels (usually around -0.35%/°C). In practice, this means more stable energy production during hot, sunny days, which matters particularly for installations in warmer climates or on heavily sun-exposed roofs.
Is Vikram Solar a reliable, bankable manufacturer of solar panels?
Vikram Solar is an India-based Tier 1 manufacturer, meaning financial stability, in-house production lines, and a proven track record supplying large bankable projects. The HYPERSOL G12R panels comply with international IEC and UL standards, which simplifies project financing and insurance. Tier 1 status reduces investor risk of the manufacturer exiting the market before the warranty period ends.
