KSL Cleantech

What KSL Cleantech does

KSL Cleantech Limited is an Indian solar EPC (Engineering, Procurement, Construction) firm headquartered in Kolkata, founded in 2006, that designs, procures, installs, and commissions solar photovoltaic systems ranging from small rooftop installations (18 kWp) to multi-megawatt utility-scale plants (up to 6 MWp). The company serves four primary customer segments — industrial and commercial, government and institutional, utility-scale, and irrigation/drinking water — with a project portfolio spanning more than 400 completed installations across 17+ Indian states. Its technology stack centers on solar PV using TOPCon modules sourced through an authorized channel partnership with Adani Solar, complemented by Battery Energy Storage Systems (BESS), Green Hydrogen infrastructure, and AI-driven monitoring with predictive maintenance analytics, drone inspections, and PVSYST design simulations.

Revenue is generated through five streams: one-time Solar EPC project fees, recurring Operation & Maintenance subscription contracts with 24/7 monitoring, Solar IPP/Open Access asset ownership under 25-year power purchase agreements, Green Hydrogen infrastructure sales, and Financial & Energy Advisory professional services. Pricing is quote-based and project-specific, with a representative 200 kWp system priced at approximately ₹59.9 lakh and delivering 28-40% reductions in annual energy cost with 3.5-4.5 year payback. Distribution is primarily direct enterprise field sales targeting CXOs and government decision-makers, supplemented by a website-based solar calculator, content marketing, and event participation.

The company is privately held and founder-driven, with no disclosed external investors, no subsidiaries, and no public market presence. Management is led by Managing Director Dhiraj Bhagchandka (also founder of Kirti Solar Limited), Director Aditya Bhagchandka heading business development, and Executive Rachit Jalan overseeing Pan-India project expansion. Operations are supported by regional offices in New Delhi (North India), Cuttack (Odisha operations), and Raipur (Chhattisgarh sales) in addition to the Kolkata headquarters.
