Understanding PM Surya Ghar: Muft Bijli Yojana
The PM Surya Ghar: Muft Bijli Yojana was launched by the Government of India with a massive outlay of ₹75,000 crore to provide free electricity (up to 300 units per month) to 1 crore households across India.
Under this scheme, residential homeowners, housing societies, and residential welfare associations (RWAs) can install grid-connected rooftop solar systems with direct financial subsidy disbursed directly into their bank accounts.
Subsidy Structure Breakdown (2025–2026)
The subsidy scheme is segmented based on the sanctioned capacity of the residential rooftop solar plant:
| System Capacity | Central Government Subsidy (CFA) | Estimated System Cost (Approx) | Net Cost to Customer |
|---|---|---|---|
| 1 kW Rooftop Solar | ₹30,000 | ₹65,000 – ₹75,000 | ₹35,000 – ₹45,000 |
| 2 kW Rooftop Solar | ₹60,000 | ₹1,25,000 – ₹1,40,000 | ₹65,000 – ₹80,000 |
| 3 kW to 10 kW Rooftop Solar | ₹78,000 (Capped) | ₹1,85,000 – ₹2,10,000 (for 3kW) | ₹1,07,000 – ₹1,32,000 |
| Group Housing / RWAs (up to 500kW) | ₹18,000 per kW | ₹55,000 – ₹62,000 / kW | Varies by total load |
Step-by-Step Application Process for Tamil Nadu Residents

2. Feasibility Approval & Vendor Selection: Once TANGEDCO verifies transformer capacity, select IVR Energy as your certified EPC partner.
3. Site Engineering & Installation: Our engineering team conducts shadow analysis, installs Tier-1 Mono PERC/TOPCon modules, inverters, and lightning arrestors conforming to MNRE specifications.
4. Net Meter Commissioning & Inspection: TANGEDCO officials inspect the setup and replace the existing single/three-phase meter with a bi-directional net-meter.
5. Subsidy Disbursal: Upon uploading the commissioning report and cancelled cheque on the portal, the central subsidy is directly transferred to your bank account within 30 working days.
Why Work with an Empaneled Turnkey EPC Like IVR Energy?
While anyone can buy components off the shelf, subsidy clearance requires strict adherence to BIS and MNRE quality guidelines, including DCR (Domestic Content Requirement) certified modules and CE-marked grid-tied inverters.
IVR Energy manages the entire liaison process with local TNEB section offices, ensuring seamless net-metering approvals without delays.
