- What happened: Solarium Green has secured two domestic orders totaling INR 22.5 crore to supply high-efficiency 715/720 Wp TOPCon bifacial solar modules across Karnataka, Tamil Nadu, Andhra Pradesh, and Puducherry.
- Why it matters: The shift toward high-wattage TOPCon technology indicates a growing preference among Indian developers for advanced modules to optimize land-use efficiency and project yields.
- Watch: Monitor the delivery timelines, with the first shipments commencing within seven days and final project completion scheduled by mid-May 2026.
Background and Context
As the Indian solar sector accelerates its transition toward higher efficiency standards, manufacturers are increasingly pivoting toward n-type TOPCon (Tunnel Oxide Passivated Contact) technology. Solarium Green has emerged as a key player in this segment, recently securing two significant domestic purchase orders totaling INR 22.5 crore. These contracts underscore the rising demand for high-wattage, bifacial modules capable of delivering superior performance in India’s diverse climatic conditions.
Key Details
The company has secured two distinct orders. The first contract, valued at INR 14.10 crore (excluding GST), involves the supply of BIS-certified 715/720 Wp TOPCon n-type bifacial dual-glass solar panels. These modules are destined for grid-connected projects spread across Karnataka, Tamil Nadu, and Andhra Pradesh. The scope of this order is comprehensive, encompassing inspection, packaging, and logistics to the designated project sites, with delivery set to commence within seven days of buyer confirmation.
The second order, valued at approximately INR 8.40 crore (excluding GST), focuses on the supply of non-DCR TOPCon half-cut 132-cell G12 modules, also rated at 715/720 Wp. These units are earmarked for projects in Puducherry. To ensure long-term reliability, the modules are backed by a 12-year product warranty and a 30-year linear power output warranty. The delivery schedule for this second tranche is set for completion by mid-May 2026.
What This Means for EPCs and Developers
For EPC contractors and developers, these orders highlight the industry’s rapid adoption of G12-based TOPCon technology. The move toward 715/720 Wp modules allows for a reduction in the total number of modules required per megawatt, thereby lowering Balance of System (BoS) costs and optimizing land utilization. Developers operating in Southern India should note the supply chain readiness of domestic manufacturers to meet high-capacity requirements on short notice.
What Happens Next
The immediate focus for Solarium Green will be the rapid deployment of the first order, given the seven-day delivery window. Industry stakeholders will be monitoring the performance of these TOPCon modules in the field, particularly their degradation rates and energy yield in high-temperature environments. Furthermore, the completion of the Puducherry project by May 2026 will serve as a benchmark for the manufacturer’s ability to manage long-term supply commitments amidst evolving market pricing.
