CFA India: MNRE Residential Solar Grant Component

Definition

Central Financial Assistance (CFA) is the grant component of MNRE solar incentive schemes. For residential rooftop solar (Phase II), CFA covers 40% of cost up to 3 kW + 20% on 3–10 kW.

Key Takeaways

CFA = Central Financial Assistance (MNRE grants).
Residential rooftop: 40% for first 3 kW, 20% for 3–10 kW.
Disbursed via DISCOM/MNRE process after installation.
Combined with state subsidies in some cases.

How CFA Works

CFA is not a lump-sum handout — it is calculated in slabs against the system’s benchmark cost, then paid out only after the system is live. For an individual residential rooftop system, the calculation works like this:

First 3 kW of capacity: 40% of the applicable cost is covered by CFA.
Next 3–10 kW of capacity: 20% of the applicable cost is covered by CFA.
Disbursement timing: the subsidy is released after installation, commissioning, and net-metering sign-off, routed through the DISCOM and MNRE’s administrative process rather than paid upfront to the homeowner or vendor.
Scope: CFA applies only to residential rooftop solar under this scheme. Commercial and industrial systems are not eligible for this particular grant and instead move through their own permitting and financing paths — see our comparison of commercial vs. residential solar permit design for how the two tracks diverge.

Worked Example: 5 kW Residential System

Take a 5 kW rooftop system, which spans both CFA slabs:

First 3 kW → 40% CFA
Remaining 2 kW (within the 3–10 kW slab) → 20% CFA

If system cost is assumed to scale evenly per kW (a simplification, since real per-kW costs can vary with system size), the blended subsidy works out to roughly (3 × 40% + 2 × 20%) ÷ 5 = 32% of total system cost. Push the system size closer to 10 kW and the blended percentage drifts down toward 20%; stay at or under 3 kW and the full 40% applies.

CFA eligibility and disbursement often move in step with local permitting and interconnection timelines — our Solar Permits India state-wise guide covers how approval timelines vary by state, which in turn affects how quickly a subsidy claim can clear the DISCOM. Because CFA applies only to residential systems, it’s also worth understanding how rooftop solar works from sizing through commissioning, and how residential solar installations are typically scoped for homeowners applying for the subsidy.

Frequently Asked Questions

6 commonly searched questions about CFA (Central Financial Assistance).

What does CFA stand for in solar subsidy schemes?

CFA stands for Central Financial Assistance — the grant component that MNRE provides under residential rooftop solar schemes to lower the upfront cost for homeowners.

How much subsidy does CFA provide for a residential rooftop system?

Under the Rooftop Solar Programme Phase II, CFA covers 40% of the benchmark cost for the first 3 kW of capacity and 20% for the next 3–10 kW. As system size grows past 3 kW, the blended subsidy percentage gradually moves down toward 20%.

Is CFA available for commercial or industrial solar projects?

No. CFA under this scheme is limited to residential rooftop solar. Commercial and industrial installations follow different financing and incentive structures, including separate permitting processes.

When is the CFA subsidy actually paid out?

CFA is disbursed after the rooftop system is installed and commissioned, following verification through the DISCOM and MNRE administrative process — it is not paid upfront before installation begins.

Can CFA be combined with state-level solar subsidies?

In some states, yes. CFA from MNRE can stack with additional state government incentives, though the combined benefit and eligibility rules vary by state.

Does CFA cover the full cost of a rooftop solar system?

No. CFA only offsets a portion of the system cost — 40% up to 3 kW and 20% on the 3–10 kW slab — so the homeowner still funds the remaining balance directly or through financing.
