What ZunRoof does

ZunRoof Tech Pvt Ltd, operating commercially as zunsolar (previously zunroof), is an India-based solar rooftop Engineering, Procurement and Construction (EPC) company founded in 2016 and headquartered in Gurgaon. The company designs, supplies, and installs on-grid, off-grid, and hybrid solar rooftop systems for residential homeowners, commercial and industrial establishments, and housing societies across more than 75 Indian cities. Its site-assessment process uses Image Processing for shadow profiling, VR-based 3D rooftop layouts, and Data Analytics to size systems against a customer's historical electricity consumption; an IoT-powered remote monitoring stack feeds real-time generation and savings data to the customer's mobile app.

The business operates a sales-led go-to-market combining field visits by solar experts, inside sales via phone and WhatsApp, and a self-serve mobile app. Customers pay a milestone-based 20% deposit at order confirmation, with the remainder due across installation and commissioning (target 25-50 days from layout approval). Revenue is generated from one-time hardware sales of Tier-1 panels, inverters, mounting structures and electrical components, professional installation services, and the facilitation of solar loans and 0% EMI financing through partner lenders. ZunRoof is empaneled with MNRE and multiple state renewable energy agencies (HAREDA, UPNEDA, TSREDCO, PSPCL), enabling it to channel up to 40% government subsidies and process net-metering approvals on behalf of customers. The company claims 40,000+ installations, ₹60 crore in cumulative customer electricity-bill savings, and 4x year-on-year growth since 2016.

ZunRoof's broader product surface extends beyond EPC into ZunPulse (IoT home products such as smart doorbells) and ZunMarket (an online marketplace for solar accessories), positioning the company as a distributed solar-and-smart-home platform rather than a pure installer. It is a privately held company with disclosed backing from the Godrej family office and ANBG Enterprise across multiple rounds between 2020 and 2025, totalling roughly $9.85M in funding.
