At Waaree Energies Limited, innovation is not an option, it’s embedded in everything we deliver. One of the key enablers of higher energy output and long-term reliability in our solar modules is the use of HTAR (High Transmittance Anti-Reflective) Glass, a premium front-glass technology that sets Waaree apart in the global solar industry.

While many manufacturers still rely on traditional ARC (Anti-Reflective Coated) glass, Waaree has already adopted HTAR glass as a standard across its solar module range, ensuring our customers get maximum performance from every installed watt.

What Makes HTAR Glass Exceptional?

HTAR glass is an ultra-clear, low-iron tempered solar glass with a permanent coating, designed to capture more sunlight and reduce reflection losses. Unlike coated surfaces that degrade or peel over time, HTAR’ ensures decades of stable optical performance.

Here’s the key performance edge:

HTAR glass offers more than 1% higher transmittance than conventional ARC-coated glass, which directly translates to higher energy yield per module.

By integrating HTAR glass into all Waaree modules, we deliver:

• Higher power output due to improved light capture
• Better performance in low-light and diffused sunlight
• Reduced soiling and durable coating

Trusted Across Terrains and Climates

To ensure the long-term performance of HTAR glass in real-world environments, Waaree has subjected it to extensive reliability testing. This includes exposure to extreme climatic conditions and accelerated aging protocols, which includes extended UV exposure & extended thermal stress tests, which demonstrates exceptional durability of Waaree’s modules with HTAR glass.

In real world scenario, from high dust regions to coastal humid regions, snow prone regions, Waaree modules with HTAR glass have demonstrated consistent performance helping customers maximize returns in all types of installations.

Why It Matters to You

HTAR glass isn’t just a material choice, it’s a reflection of Waaree’s commitment to high-performance, high-efficiency solar solutions. For project developers, EPC players, and end-users, this means Increased energy yield, Lower levelized cost of energy & more reliable generation, year after year
