Premier Energies announces launch of solar cell line 620W DCR Topcon modules

The renewable energy company, Premier Energies Ltd. on Friday, August 22, announced the commercial operation of its 1.2 GW N-Type G12R solar cell line and the launch of India’s first 620 W Domestic Content Requirement (DCR) compliant Topcon solar modules. The company said the introduction of the G12R N-Type solar cell technology makes it one of the first in the country to bring this advancement to market.

According to its stock exchange filing, the next-generation 620 W modules are powered by Tunnel Oxide Passivated Contact (TOPCon) architecture, enabling higher power density, improved temperature performance and stronger efficiency in low-light conditions.

The modules are designed in a rectangular G12R format to allow higher string power and optimized balance-of-system (BOS) costs, making them suitable for utility-scale solar parks, as well as commercial and industrial rooftops. “This launch represents a significant milestone in India’s transition to high-efficiency solar,” said Chiranjeev Saluja, Managing Director and CEO of Premier Energies.

He added, “As one of the first companies to introduce 620 W DCR modules, we are offering a future-ready solution to help investors and consumers extract more value from every ray of the sun.”

The company highlighted that the 620 W G12R Topcon modules have been engineered to maximise energy yield in space-constrained rooftops and high-capacity ground-mounted projects. With next-generation Topcon architecture, they are said to deliver superior conversion efficiency compared to conventional PERC modules.

The rectangular design further supports improved system layout, higher string power and reduced overall costs. Premier Energies also noted that the modules are built for durability, withstanding India’s climatic conditions such as high heat, humidity, dust and strong winds.

The company said the modules have been developed to address evolving consumer needs, ensuring higher returns while lowering carbon impact.

Shares of Premier Energies closed 1.24% lower at ₹1,010 apiece on the NSE.

Premier Energies reported a 55% jump in consolidated net profit at ₹307.8 crore for the June quarter of FY26, supported by higher revenues from core operations. The firm, engaged in the production of solar cells and modules, had posted a net profit of ₹198.1 crore in the April-June quarter of FY25.

Revenue for Q1 stood at ₹1,869.6 crore, compared to ₹1,668.7 crore in the same period last year. Profit before tax (PBT) rose to ₹402.9 crore from ₹245.7 crore a year earlier. The company reiterated its commitment to India’s clean energy mission of achieving 500 GW by expanding operations through investments in advanced technologies.

During the quarter, Premier Energies successfully commissioned its 1.4 GW module and 1.2 GW TOPCon (series) cell lines, raising total capacity to 5.1 GW and 3.2 GW, respectively. Commercial production from the new facilities is expected to commence soon. The company aims to increase solar cell and module manufacturing capacity to 8.4 GW and 11.1 GW by June 2026.

It is also diversifying into related areas such as ingots and wafers, battery storage, and solar inverters, with the goal of becoming one of the world’s largest fully integrated renewable energy equipment manufacturers.
