The Vikram Solar HYPERSOL VSMDH.66.AAA.05 (690-715) series are modules designed for maximum yield in projects where every meter of construction and every hour of installer work counts. The use of N-type cells minimizes typical operational losses and helps maintain stable performance over time, even under more demanding conditions. The bifacial design allows for a real increase in energy production by utilizing reflected light - particularly on roofs with light-colored surfaces and in ground-mounted farms with properly prepared substrates.

A key feature of this series is 0% negative power tolerance, which simplifies string design and reduces the risk of losses due to underestimating module parameters. The modules are designed with a focus on PID resistance and lower susceptibility to LID and LeTID effects, making them well-suited for commercial and large-scale installations, where predictability of production and energy costs are priorities. This is a good choice for C&I and utility investors who want to increase yield without complicating the project.

Common questions

6 answered
Is the Vikram Solar HYPERSOL VSMDH.66.AAA.05 (690-715) series still available for purchase?
The HYPERSOL VSMDH.66.AAA.05 series has been discontinued from current production by Vikram Solar and replaced by newer variants within the Hypersol lineup. Availability is now limited to distributor stock clearance and remaining batches from earlier shipments. For new projects, check the manufacturer's current lineup or ask your supplier about remaining stock, as replacement models may have slightly different power ratings and dimensions.
How much extra energy does the bifacial design deliver on HYPERSOL VSMDH.66.AAA.05 panels?
These modules feature bifacial technology with bifaciality up to 80%, meaning the rear side generates as much as 80% of the front side's power under full illumination. In practice, with a high-albedo surface (white gravel, light-colored roofing) or elevated ground-mount installation, the realistic annual energy gain is typically 5-15%, depending on surrounding albedo and mounting height.
How do the N-type cells in HYPERSOL differ from standard P-type PERC cells?
The N-type cells used in this series have a lower power temperature coefficient (-0.3%/°C) than typical P-type cells, meaning smaller production losses on hot days. N-type technology is essentially immune to LID degradation and far less susceptible to LeTID, so the module retains higher efficiency throughout its service life compared to comparable P-type PERC panels.
What warranty comes with Vikram Solar HYPERSOL VSMDH.66.AAA.05 panels?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing at least 87.4% of initial output after 30 years. In the first year, output is guaranteed at 99% of nameplate power, a stronger term than the standard 97-98% offered by many competitors.
What does 0% negative power tolerance on HYPERSOL panels mean, and why does it matter?
Power tolerance defines how much a module's actual output can differ from its rated label value. With 0% negative tolerance, the manufacturer guarantees every unit meets or exceeds its rated power, never falling short. For system designers, this means confidence in actual string output without risk of underestimating energy production, which simplifies inverter sizing and ROI planning.
Are HYPERSOL VSMDH.66.AAA.05 panels suitable for large ground-mount and utility-scale solar farms?
Yes, given their high power output (up to 715 Wp), dimensions of roughly 2384x1303 mm, and weight of about 39.5 kg, this series is designed primarily for commercial and industrial (C&I) installations and ground-mounted solar farms. The bifacial design further boosts profitability in ground-mount projects with high-albedo surfaces, while PID resistance ensures stable operation across long series strings.
