How much assistance is modelled?
For eligible homes, central assistance is modelled at ₹30,000 per kW for the first 2 kW and ₹18,000 for the next 1 kW, capped at ₹78,000. Tamil Nadu assistance is ₹5,000 for 1 kW, ₹10,000 for 2 kW and ₹22,000 for 3 kW and above. This calculator models state support only up to 10 kW.
| System | Central | Tamil Nadu | Total |
|---|---|---|---|
| 1 kW | ₹30,000 | ₹5,000 | ₹35,000 |
| 2 kW | ₹60,000 | ₹10,000 | ₹70,000 |
| 3–10 kW | ₹78,000 | ₹22,000 | ₹1,00,000 |
Who can receive the Tamil Nadu portion?
The Tamil Nadu order covers the first 1 lakh eligible beneficiaries registered on the PM Surya Ghar portal from 5 August 2026, subject to allocation and approval. The household assistance is for residential connections. A business installation should not include it in its financial plan.
Registration alone is not a promise of payment. Check the latest requirements and available allocation with the official portal before purchasing. This website is not a government portal and does not approve applications.
What to check before installation
- Read the current scheme and utility requirements on the official portals.
- Confirm that your electricity connection, proposed capacity and application meet the requirements.
- Check the vendor’s current registration and the required domestic-content and approved-equipment criteria.
- Complete the necessary application and approval stages before proceeding.
- Keep the equipment documents, invoices and commissioning records needed for the claim.
Ask for the vendor’s actual registration details. Arc Solar does not claim empanelment or scheme approval on this website without verified registration evidence.
When is the subsidy paid?
Assistance follows the required commissioning and approval process. It is not an automatic discount at purchase. For a 3 kW system with a planning budget of ₹1.80 lakh–₹2.20 lakh, the potential ₹1.00 lakh assistance would reduce the eventual net cost to ₹80,000–₹1.20 lakh only if both portions are approved and paid.
The estimate shows both the full budget and the conditional net amount. Turn off the subsidy option to plan without relying on a grant.
