The Waaree AHNAY series are bifacial glass-glass modules designed to genuinely increase energy yield from the same installation surface - especially on sites where the rear side of the module also generates electricity. The use of dual-glass construction enhances weather resistance and reduces the risk of micro-cracks, which is crucial for long-term operation. The AHNAY variants are available in both Mono PERC and N-type TOPCon technologies, making it easier to select the right module for project requirements and performance profiles (e.g., higher parameter stability over time). An additional advantage is resistance to PID and optimized heat dissipation thanks to split junction box solutions, which help limit the risk of hotspots and performance degradation. This is the series for investors building installations on flat roofs, PV farms, and commercial sites, where low energy costs and predictable power generation even under diffuse light and partial shading matter.

Common questions

6 answered
What is the difference between Waaree AHNAY Mono PERC and N-type TOPCon panel variants?
Both technologies in the AHNAY series share the same dual-glass bifacial construction, but differ mainly in long-term stability and degradation rate. TOPCon modules have a lower annual degradation rate and higher output efficiency than standard PERC, resulting in higher energy yield over the system's lifetime. PERC remains a more budget-friendly option, well suited for cost-sensitive projects.
What is the maximum power output and efficiency of the Waaree AHNAY panel?
Top variants in the AHNAY series reach up to 665 Wp with 132 half-cut cells, and module efficiency reaches around 21.3 percent. This is a high value for dual-glass bifacial modules, allowing more energy to be generated from the same roof or ground-mount area compared to older, less efficient series.
What warranty does Waaree offer on the AHNAY series, and what does it cover?
The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. This means protection against factory defects for over a decade, plus a predictable, guaranteed power degradation curve over three decades of operation, which simplifies ROI planning for commercial installations and PV farms.
Do Waaree AHNAY bifacial panels actually increase energy production compared to standard modules?
Yes, the dual-glass construction lets the rear side of the module capture light reflected from the ground, roof, or surroundings, boosting total energy yield, especially over bright, reflective surfaces like gravel or white roofing. The actual gain depends on mounting height and ground albedo, but in practice AHNAY installations outperform comparable monofacial panels of the same surface area.
Are Waaree AHNAY modules PID-resistant and suitable for large-scale PV farms?
Yes, the AHNAY series has certified resistance to potential-induced degradation (PID), which matters in large installations with long strings and high system voltage. A split junction box design also improves heat dissipation and reduces hotspot risk, making this series well suited for PV farms and large commercial rooftop installations.
Does Waaree offer the quality assurance typical of Tier 1 solar manufacturers?
Yes, Waaree is an India-based Tier 1 manufacturer, meaning it has financial stability, its own production capacity, and a documented track record of supplying modules to large commercial and industrial projects worldwide. Tier 1 status increases confidence in the long-term warranty, since the manufacturer has the real capacity to honor it throughout the full 30-year power warranty period.
