What Suntastic Solar Systems does
Suntastic Solar Systems (legally Suntastic Engineering Private Limited) is a South India-based solar EPC contractor and module manufacturer founded in August 2016 and headquartered in Chrompet, Chennai. The company designs, supplies, installs, and maintains grid-connected (On-Grid), Off-Grid, and Hybrid solar PV systems with Battery Energy Storage Systems (BESS) for residential, commercial, industrial, and government customers. Its in-house solar PV module manufacturing capability (with a 1,000 kW milestone achieved in April 2018) and its role as a SOFAR Solar channel partner for inverters provide some vertical integration into component supply. The company markets cumulative metrics of 10 MWp+ installed capacity, 22,000+ customers, and 25,000+ completed projects, alongside 5,000+ home lighting systems and 20,000+ LED lighting systems.
The business operates multiple parallel revenue streams: project-based EPC installation fees, hardware sales from in-house manufactured PV modules, distribution margins on SOFAR inverters, facilitation margins on government subsidies (notably PM Surya Ghar for residential customers up to Rs.78,000), and recurring monitoring/maintenance contracts. Pricing is largely one-time and project-based, with ROI of 3–5 years claimed for residential systems; financing at ~7% interest is offered on rooftop solar up to 3 kW. The company is recognised as a 'S' Class Contractor in Military Engineer Services (MES) and is empanelled with multiple government bodies including MNRE, TEDA, ANERT, KSEB, TANGEDCO, PWD, and Railways, providing access to government tender channels.
Suntastic pursues a multi-channel go-to-market: direct-to-consumer residential sales via website inquiry forms and phone outreach; channel partner flows for inverter distribution and MNRE subsidy facilitation; and a dedicated enterprise field sales corporate division handling large industrial, commercial, real estate developer, and government projects. Office locations span Chennai (HQ), Coimbatore (regional operations), Palakkad, and Trivandrum, covering the South Indian market. The leadership team is founder-led by Managing Director G.K. Arunraj, with Directors A. Sowmiya and K. Kalaivani and CEO L. Mohamed Shoaib; the company is privately held with no disclosed external institutional investment.
