Chennai gets strong sunlight for most of the year, which makes rooftop solar one of the most practical investments for homes and businesses. RS Technologies designs and installs rooftop solar systems for homes, apartments, offices, schools and factories, along with solar-powered CCTV, street lights, water pumps and gate automation.
Under the PM Surya Ghar Muft Bijli Yojana, homes can receive a central subsidy of ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW — up to ₹78,000 for a system of 3 kW or more. Tamil Nadu’s 2026 budget announced an additional state top-up of up to ₹22,000; the state’s detailed guidelines are still awaited.
The subsidy requires DCR (domestically manufactured) panels and an installation by a vendor registered on the national portal. Always ask your installer to show their registration before you sign.

For offices, schools, factories and warehouses with large daytime loads, rooftop solar offsets expensive commercial tariffs. We size these systems from your load profile and roof area, and can combine them with solar-powered CCTV and lighting for perimeter areas.
| System | Typical market range |
|---|---|
| On-grid 3 kW home system with DCR panels, before subsidy | ≈ ₹1.8 – ₹2.2 lakh |
