From KW to GW: A roller coaster ride – Sova Solar Ltd


To take our manufacturing excellence to the next level we have completely automated our manufacturing facility in January.  We aim to achieve 1 GW manufacturing capacity by 2018.

Subrata Mukherjee, Managing Director, Sova Solar Ltd

Established in 2008, Kolkata-based Sova Solar Ltd. is one of the key players in the field of renewable energy. The company has gained expertise in manufacturing and marketing cost effective, high quality solar photovoltaic modules for grid connected and off-grid power plants, solar water pumps, solar street lights etc. Continuing its effort on innovating advanced solutions, Sova Solar has introduced silicon crystalline based products using high quality raw materials.

Talking on the company’s product offering, Subrata Mukherjee, Managing Director, Sova Solar Ltd said, “Our products range is from 3 Wp to 325 Wp solar panels. Our photovoltaic modules are produced with the efficiency of up to 17.0 per cent with positive tolerance up to 4.9 Wp in compliance with international standard.”

The panels are constructed with Anti Reflective Coating (ARC) toughened low iron, textured high light transmission glass on the front and a three layer fluropolymer tedlar back sheet to protect the panel from moisture and long term weathering. Our modules are PID Free and FSI tested. The panels are finished with an silver anodised aluminium frame with mounting holes pre-drilled and a junction box with cables. Our products are unique in incorporating Si-Cys cells. This format provides flexibility in the design of panels with the possibility of different sizes and electrical characteristics. Our panels offer a number of benefits over competing types of panels. Our modules generates more power than other in low light, cell design provides better output by rendering resistance power less.

Achieving manufacturing prowess

Sova Solar is operating out of its manufacturing facility at Durgapur, West Bengal. Powered with highly equipped machineries of German technology, the firm has excelled in production of crystalline solar photovoltaic module from its facility at Export Promotion Industrial Park, Banskopa started 2009-10. Technological support from Spire Corporation, Bedford, USA and Team Technik, Germany gave the much-desired boost to the company. Today Sova Solar has the installed capacity of production of PV modules is 200 MW per year. Our infrastructure 500 MW is ready and our vission to reach 1GW by 2018-19.

“To take our manufacturing excellence to the next level we have completely automated our manufacturing facility in January.  This will help us to provide world-class PV modules within a reduced timeline and higher, efficiency ” Mukherjee adds. Further, commenting on the company’s expansion plans, he said, “We aim to achieve 1 GW manufacturing capacity by 2018.” The company has also announced new international EPC venture in collaboration with Japanese and Taiwanese partners.

Leading with innovation

  • High Reliability tests to ensure modules to withstand high temperature, humidity, pressure, wind loads.
  • Stringent EL-Tests pre-lamination and post lamination to ensure micro cracks free modules manufactured in facility.
  • Stringent HoT Spot tests to ensure modules are free from hot-spots.
  • Mechanical load Test to ensure modules exceedingly perform higher than 5,400 Po.
  • Stringent UV exposure tests to ensure high module performance and lowest UV degradation after test compared to peers.
  • Maintain the lowest Linear Degradation Chart by superior Technology compared to Peers also providing positive tolerance to every module enabling higher kwp/Kwh faster.
  • Stringent reliable test ensures that only the best is offered to our client


Today Sova Solar is an approved vendor of Steel Authority of India Ltd. (SAIL) and is regularly working with government companies and organisations like Bharat Heavy Electricals Ltd (BHEL), Directorate General of Supplies & Disposals (DGS&D), Power Grid Corporation of India Ltd (PGCIL), and Bharat Electrics Ltd. Governmental customers we are regular supplier numerous large commercial EPC players accross all  segments like DCR, MII, open

Beyond Indian skies

Associated with the “Center of Excellence for Green Energy and Sensor Systems (CEGESS) Dept. of Indian Institute of Engineering Science & Technology, Shibpur, Howrah, Sova Solar has been pioneering in the field of solar PV technology. In association with AW Solution GmbH and Professor Markus Amendt of Berlin University Sova Solar Limited has been one of the few companies of India to set its foot at European Soil. The company has announced a commercial tie-up with Rogrees-Boeki, Japan to facilitate. “Today, apart from creating waves in the Indian solar market, Sova’s are being modules used in large number of projects in Germany and Japan,” informed Mukherjee.
