Onix Solar Energy Limited has commenced development on its 1,200 MW solar module manufacturing facility. The state-of-the-art plant will focus on high-efficiency TOPCon and P-Type technologies with outputs up to 640 WP, leveraging capital from its recent rights issue to accelerate its 10 GW renewable energy roadmap.

MUMBAI, INDIA — Onix Solar Energy Limited (BSE: 513119), a fast-emerging player in India's renewable infrastructure market, has formally initiated the engineering phase for its new 1,200 MW solar module manufacturing facility. According to official corporate statements and standard exchange notifications finalized today, June 22, 2026, the industrial project will house high-capacity automated assembly lines dedicated entirely to high-efficiency Tunnel Oxide Passivated Contact (TOPCon) and advanced P-Type photovoltaic (PV) modules.

The strategic rollout coincides with a massive policy push by the Union Government to strengthen domestic supply chains and reduce reliance on imported solar components. By setting up the 1,200 MW solar module manufacturing facility, the Mumbai-headquartered company transitions from its historic engineering services model into a vertically integrated, asset-backed manufacturing producer.

Technical Layout Targets Advanced High-Wattage TOPCon Output

According to the draft project blueprints compiled under internal compliance files, the 1,200 MW solar module manufacturing facility is engineered to run automated multi-busbar (10BB+) stringing matrices. The specialized machinery is optimized to process ultra-thin silicon wafers, producing high-output commercial modules ranging from 530 WP up to a maximum peak rating of 640 WP.

The facility's primary focus on N-Type TOPCon technology represents a calculated push into premium solar tiers. Compared to older, traditional photovoltaic models, TOPCon architectures provide superior cell efficiency, an improved temperature coefficient, and minimized light-induced degradation (LID) rates. These structural parameters make the panels highly attractive for utility-scale ground arrays and dense commercial rooftop installations across sun-heavy regional markets.

Capitalization Strategy Supported by Recent Balance Sheet Moves

The capital expenditure needed to fund the industrial facility follows a structured capital-raising program successfully executed by the clean-tech firm. In May 2026, Onix Solar Energy successfully floated a rights issue targeting the collection of ₹60.17 crore through the distribution of more than 11.7 million fresh equity shares to existing public holders.

Financially, the firm has seen massive balance sheet acceleration. Following its systematic corporate pivot toward full-scale clean-tech solutions in 2024, the enterprise marked record income lines. For the full fiscal year ending March 31, 2025, the firm recorded total revenues scaling up to ₹1,001.30 crore alongside an operational net profit of ₹153.46 crore. This financial momentum has driven the company's market capitalization on the Bombay Stock Exchange (BSE) to record highs in early 2026.

FAQ Section

What is the core technical benefit of N-Type TOPCon technology over standard panels?

TOPCon technology utilizes advanced passivated contact layers to minimize internal electrical loss. This enables higher cell efficiency and superior performance in low-light environments, maximizing overall power generation.

Will the output from this 1,200 MW facility be used for internal projects?

The facility's output will follow a dual distribution model. A portion will supply the company's independent power producer (IPP) projects, including its 500+ MW pipeline in Maharashtra, while the remaining supply will be sold to commercial and industrial markets.

Where is the company's main corporate headquarters located?

Onix Solar Energy Limited maintains its central corporate headquarters and executive core in Mumbai, Maharashtra.
