TriNano powers smarter solar energy with nanotechnology

India’s clean energy transition is creating opportunities for startups that solve practical challenges with innovative technology.

TriNano, a nanotechnology startup founded in January 2022, is developing advanced coatings that improve the performance and lifespan of solar panels.

Incubated at IIT Bombay’s SINE, the company was established by materials engineer and entrepreneur Dr. Harsh Sethi after identifying efficiency losses caused by dust, heat, and harsh weather conditions.

The idea emerged during visits to rural solar installations, where farmers used precious water to clean dusty solar panels.

Recognising the need for a sustainable solution, TriNano developed India’s first triple-action nano-coating designed specifically for local climatic conditions.

The coating enhances solar panel performance by combining three key features. It traps more sunlight, repels dust through a self-cleaning surface, and reduces light reflection.

As a result, solar panels generate 3% to 6% more electricity, require nearly 50% less water for cleaning, and last two to three years longer.

Unlike many conventional coatings, TriNano’s product remains effective for at least five years after a single application. Moreover, it works with solar panels of different brands, ages, and technologies.

The coating has also demonstrated consistent performance in diverse environments, including Rajasthan’s dusty conditions and Mumbai’s heavy monsoon climate.

The startup has already partnered with major companies such as Adani Green, Tata Power, and Waaree.

In addition, it has worked with housing societies and rural cooperatives. Validation from the Ministry of New and Renewable Energy has further strengthened its commercial credibility.

TriNano follows multiple business models, including on-site coating services for solar farms, partnerships with manufacturers, and collaborations for government-backed projects.

Consequently, the company aims to improve solar efficiency across both large-scale and rural installations.

Its patented coating technology also reflects heat-generating infrared rays, lowering panel temperatures and slowing long-term degradation. Furthermore, the surface resists dust, dirt, and bird droppings, reducing maintenance requirements and saving around 10,000 litres of water per megawatt every year.

Looking ahead, TriNano plans to raise ₹7.4 crore to expand its production capacity from 7 MW to 280 MW annually by 2026.

The startup also aims to enter international markets, positioning its India-developed technology as a global solution for improving solar energy efficiency.
