Mumbai: Tata Power’s solar manufacturing subsidiary, TP Solar, has reported its highest-ever quarterly production, manufacturing 1,001 MW of solar modules and 862 MW of solar cells during the April–June quarter (Q1 FY2027), reflecting the company’s continued expansion across India’s renewable energy value chain.
The milestone comes as Tata Power strengthens its domestic manufacturing capabilities while increasing supplies to both internal projects and external customers.
Revenue and Profit Rise on Strong Manufacturing Performance
TP Solar reported a 53% year-on-year increase in revenue from its solar manufacturing business to ₹2,462 crore during the quarter.
The company also posted a 287% surge in profit after tax (PAT) to ₹371 crore, driven by improved input cost efficiencies, higher production volumes, and a diversified customer mix.
According to the company, its manufacturing facility achieved plant yields of 96.3% for solar modules and 87% for solar cells, highlighting improved operational efficiency.
Growing Sales to External Customers
Tata Power said 63% of its solar module sales during the quarter were made to external customers, including the rapidly expanding rooftop solar market.
Additionally, more than half of the company’s solar cell production was sold to external buyers, reflecting increasing demand for domestically manufactured solar components as India continues to expand its renewable energy capacity.
10 GW Ingot and Wafer Facility Under Development
As part of its strategy to strengthen India’s solar manufacturing ecosystem, Tata Power is advancing plans for a 10 GW photovoltaic ingot and wafer manufacturing facility, which will be developed in two phases of 5 GW each.
The company has signed a Memorandum of Understanding (MoU) with Gopalpur Special Economic Zone (SEZ) for 128 acres of land to establish the facility.
Land development activities and environmental clearances are currently underway.
The project is expected to enhance domestic manufacturing capabilities and support India’s goal of building a self-reliant solar supply chain.
Rooftop Solar Business Maintains Strong Momentum
Tata Power’s rooftop solar business also delivered strong growth during the quarter.
The company installed 371 MWp of rooftop solar capacity, representing a 37% increase year-on-year.
Revenue from the rooftop solar business reached ₹1,350 crore, while profit after tax increased 1.7 times compared to the same period last year, supported by strong execution across residential, commercial, and industrial customer segments.
To further expand its offerings, Tata Power introduced integrated solar-plus-battery storage solutions, targeting customers seeking reliable and sustainable energy systems.
The company’s Tata Power Solaroof business has now achieved a cumulative installed capacity of 5.2 GWp, serving more than 480,000 customers across India.
Renewable Energy Portfolio Reaches 12 GW
Tata Power said its overall renewable energy portfolio has grown to 12 GW, including 5.3 GW of projects currently under construction.
The company continues to invest across the renewable energy value chain, including solar manufacturing, rooftop solar, utility-scale renewable projects, battery storage, and transmission infrastructure, supporting India’s clean energy transition.
Why It Matters
Tata Power’s record manufacturing performance highlights India’s growing capabilities in domestic solar manufacturing and renewable energy infrastructure. As the country accelerates its clean energy transition, investments across the solar value chain—from ingots and wafers to rooftop installations and battery storage—will play a crucial role in strengthening energy security, reducing import dependence, and supporting India’s net-zero ambitions.
