How PM Surya Ghar subsidy is calculated
For Tamil Nadu and other general-category states, central financial assistance is linked to eligible rooftop-solar capacity—not to the electricity bill or vendor selling price.
| Eligible category | Calculation approach | Capacity rule |
|---|---|---|
| Residential: first 2 kW | Applies the first residential capacity tier from approved configuration | Tier boundary is governed by the applicable published rule |
| Residential: additional 1 kW | Applies the additional residential tier from approved configuration | CFA is limited by the applicable published residential cap |
| GHS / RWA common facilities | Applies the published common-facility CFA rule | Subject to verified per-home and overall limits |

What determines whether the subsidy actually applies?
The amount can be estimated from capacity, but approval depends on the consumer and installation meeting scheme conditions.

What homeowners should know before deciding based on subsidy alone
Solar subsidy is capacity-linked, not bill-linked
Your bill may help determine how much solar is useful, but PM Surya Ghar CFA is calculated from eligible rooftop-solar capacity. Savings and subsidy calculators answer different questions.
Subsidy should not decide the system size
First understand the home's electricity requirement and roof feasibility, then apply the subsidy to the system that makes technical and financial sense.
| Calculator can indicate | Final process must confirm |
|---|---|
| Capacity-linked working CFA | Consumer and connection eligibility |
| Supported capacity under configured caps | Portal, DISCOM and technical compliance |
| Current configuration and source basis | Approval, commissioning and disbursal |
