SWELECT Energy Systems Ltd, formerly known as NUMERIC Power Systems Ltd, on Wednesday unveiled three new products NUMERGY HOME, NUMERGY HYBRID and NUMERGY HP under its NUMERGY brand. The launch comes as part of the company’s broader plan to expand its solar manufacturing capacity from 1 GW to 2.2 GW over the next few years, backed by an investment of ₹150 crore.
Expansion of Manufacturing Capacity
SWELECT currently operates a manufacturing facility in Coimbatore with an installed capacity of 1 GW. The company is now working towards scaling this up to 2.2 GW to meet growing demand for high-efficiency solar solutions. The expansion will be driven by its G12R TOPCon solar panels, which offer a wattage output ranging between 620 Wp and 640 Wp.
Strengthening Battery and Home Energy Solutions
The newly launched NUMERGY products further strengthen SWELECT’s portfolio of Battery Energy Storage Systems (BESS) and home energy solutions. These offerings are designed to support reliable power supply for homes and hybrid energy applications, aligning with the rising need for energy storage alongside renewable power generation.
Focus on High-Demand Northern Markets
Arulkumar Shanmugasundaram, CEO and Managing Director of SWELECT Energy Systems Ltd, said the company is actively exploring markets such as Uttar Pradesh, Bihar and other northern states. “We are exploring markets such as UP, Bihar and northern States as there is a huge demand in these markets,” he said.
He explained that demand for rooftop solar in southern states is relatively lower due to better availability of power from fossil fuel-based sources and higher awareness levels. “In southern States, the demand for renewable energy such as rooftop solar panel is less compared to northern states… however, we will take our products to southern States as well,” Shanmugasundaram added.
Lithium-Ion Price Trends and Alternatives
Commenting on the recent increase in lithium-ion battery prices, R Chellappan, Founder and Vice Chairman of SWELECT Energy Systems Ltd, said, “The recent rise in cell prices is because dollar has appreciated, and China has set price of lithium-ion slightly higher as it is reducing its export incentives on the cells.” He added that the situation is expected to stabilise soon.
Shanmugasundaram noted that despite short-term fluctuations, battery cell prices have declined over the past three years and urged stakeholders to look at the long-term picture. He also pointed to alternative technologies such as vanadium oxide and flow cells, which offer longer lifespans and could benefit the renewable sector once available at scale.
Call for Grid Readiness and Brand Refresh
Shanmugasundaram emphasised the need for government support in upgrading electrical substations to enable hybrid connectivity of wind and solar power. The company also announced a refreshed logo and tagline, marking a renewed focus on clean energy growth.
