A typical 3 Kilowatt Solar On Grid System will cost between
Rs. 1,85,000 to Rs. 2,00,000 – MNRE and ALMM Approved, Mono Half Cut 545 DCR.
What is Included?
Engineering and design; procurement; structure and panel placement; on-site civil works; inverter DC–AC electrical work; LA and earth pit work; testing and handover. This price covers end-to-end EPC-style delivery so your system is ready for commissioning and net-metering (netmeter hardware itself is not included).
Under standard conditions the netmeter (approx. ₹2,000) must be purchased by the customer because net-metering is tied to the customer’s electricity account.
GST Rates by Component
Solar projects attract different GST rates depending on the item. For clarity we list the common splits used in the industry and applied to our pricing model:
- Solar Modules (panels): GST Rate on Solar Panel (as applicable).
- Ongrid Inverter: 12%.
- BOS, Structure, Installation Service: 18%.
- Solar Industry Average GST on EPC project: 13.80% (weighted average used for industry comparisons).
These component-level GST rates affect the final invoice breakup and the effective cost to the homeowner.
Subsidy Under PM Surya Ghar Yojana
Residential customers may be eligible for central subsidies under PM Surya Ghar: Muft Bijli Yojana. For a 3 kW rooftop system the scheme structure commonly used by DISCOMs is: ₹30,000 per kW for the first 2 kW and ₹18,000 per kW for the additional 1 kW, with a total cap of ₹78,000 for systems larger than 3 kW. This means a typical 3 kW household system can receive up to ₹78,000 in subsidy subject to state/DISCOM implementation and approval processes.
For the latest application process, eligibility checks, and state-specific implementation, consult the national rooftop solar portal or your local DISCOM’s PM Surya Ghar page.

Practical Notes for Homeowners
Netmeter: Expect to pay around ₹2,000 for the netmeter; this is billed to the customer because it is registered to the household electricity account.
