CFA (Central Financial Assistance)

What Is CFA?

CFA is the principal central government financial support for distributed solar deployment in India. Multiple schemes offer CFA at various levels, each designed for a specific beneficiary category and application type. The flagship schemes are:

PM Surya Ghar Muft Bijli Yojana: Residential rooftop solar. CFA is Rs 30,000/kW for the first 2 kW and Rs 18,000 for the 3rd kW, from Rs 30,000 for a 1 kW system to a maximum of Rs 78,000 for any system of 3 kW and above.

PM KUSUM Component A: Decentralised solar plants of 500 kW to 2 MW on farmland. There is no capital CFA: the DISCOM buys the power at a pre-fixed levelised tariff, and MNRE pays the DISCOM a procurement-based incentive of 40 paise/kWh or Rs 6.60 lakh/MW/year, whichever is lower, for five years.

PM KUSUM Component B: Standalone solar pumps. Central CFA covers 30% of the benchmark or tender cost (50% in North-Eastern, hill and island states), with the state adding at least 30%. The PM-KUSUM scheme period ended on 31 March 2026; new windows depend on PM-KUSUM 2.0.

PM KUSUM Component C: Grid-connected agricultural pump solarisation, either pump by pump (up to 30% central CFA, 50% in North-Eastern, hill and island states, plus any state share) or at feeder level (30% central CFA in CAPEX mode, with the balance financed through loans).

Phase-II Grid-Connected Rooftop Programme (historical): The pre-2024 residential rooftop scheme, with CFA of 40% up to 3 kW and 20% from 3 to 10 kW. It ran through DISCOM-empanelled vendors and has been replaced by PM Surya Ghar for homes. Commercial and industrial rooftops did not get CFA under it.

CFA is not a loan, tax credit, or rebate. It is a capital subsidy that reduces the upfront cost of the solar system. For a typical 3 kW residential rooftop costing Rs 1.65 lakh, the PM Surya Ghar CFA of Rs 78,000 cuts the net investment by 47%. A few states have notified their own top-ups; check the state’s own notification before counting on one.

Why CFA Matters

CFA matters because it transforms solar from a good long-term investment into an irresistible immediate opportunity. Without CFA, a 3 kW residential system in Gujarat has a payback period of 5 to 6 years. With CFA, the payback drops to 2.5 to 3 years. For a middle-class household, this difference is the deciding factor between “maybe next year” and “let’s install this month.”

For farmers under PM KUSUM, CFA helped convert diesel pump dependence into solar self-reliance while the scheme ran (its scheme period ended on 31 March 2026). A 5 HP solar pump costing Rs 3.50 lakh received Rs 1.05 lakh from central CFA and at least Rs 1.05 lakh from the state. The farmer’s contribution of Rs 1.40 lakh could be recovered within 2 to 3 years through diesel savings of Rs 50,000 to Rs 70,000 annually. Without CFA, the Rs 3.50 lakh upfront cost would be prohibitive for most small farmers.

For the national solar mission, CFA is the demand-pull mechanism that accelerates deployment. PM Surya Ghar’s target of rooftop solar for 1 crore households depends on CFA making residential systems affordable. Every rupee of CFA draws in private spending by the household on solar hardware, installation labour, and grid connection.

For installers like Heaven Green Energy, CFA compliance is a core competency. As Gujarat’s #1 ranked PM Suryaghar installer, with 10,000+ installations company-wide, we manage the entire CFA lifecycle, from portal registration and DISCOM feasibility approval to commissioning inspection and e-token redemption. Our average CFA disbursement time is 5 to 7 weeks.

How CFA Works

The CFA process follows a structured sequence from application to disbursement, with checkpoints at each stage to prevent fraud and ensure quality.

Step 1, Portal registration: The beneficiary registers on the scheme portal. For PM Surya Ghar, this is the national portal (pmsuryaghar.gov.in). The applicant submits the electricity connection details and bank account details in their own name, with a cancelled cheque, bank statement or passbook scan as proof.

Step 2, DISCOM feasibility: Under the Electricity (Rights of Consumers) Rules, applications for systems up to 10 kW are deemed accepted without a technical feasibility approval. Until a state has put this into effect, the local DISCOM (UGVCL, MGVCL, PGVCL or DGVCL in Gujarat, or Torrent Power in Ahmedabad, Gandhinagar and parts of Surat city) checks feasibility, such as distribution transformer capacity, where its regulations require it.

Step 3, Vendor selection: The beneficiary selects a vendor registered on the PM Surya Ghar national portal and agrees the price with that vendor; there are no government-fixed rates. Heaven Green Energy appears on all four Gujarat DISCOM empanelment lists and the national PM Surya Ghar vendor directory.

Step 4, Installation: The vendor installs domestically manufactured (DCR), ALMM-listed modules, a BIS-certified inverter and balance of system components that meet the scheme’s minimum technical specifications. Installation typically takes 1 to 3 days for residential systems.

Step 5, Net metering: The DISCOM installs a bidirectional net-metering meter, enabling the consumer to export surplus solar generation to the grid and receive adjustment credits.

Step 6, Inspection: DISCOM engineers inspect the installation (the State Nodal Agency (SNA) may also sample-check installed systems) for compliance with MNRE technical standards, ALMM module verification, and safety protocol adherence.

Step 7, E-token activation: Once the documents are uploaded and the DISCOM inspection is complete, the e-token generated at application is activated with the CFA amount for the actual installed capacity.

Step 8, Redemption and release: The consumer logs in to the portal and redeems the e-token. The CFA is processed within 15 days of DISCOM approval and paid to the bank account on the portal, or to the loan account first if the system was financed.

Important: Mismatched documentation is a common cause of CFA delays. The bank account submitted on the portal must be held by the applicant, and the name should match the electricity connection. Keeping your Aadhaar seeded to that account is a sensible precaution, but the guidelines require the bank proof, not Aadhaar seeding.

Visual Explanation

Real-World Example

The Patel family in Ahmedabad’s Bopal area decides to install a 3 kW rooftop solar system under PM Surya Ghar. Their monthly electricity bill averages Rs 3,500, and they want to reduce it to near zero.

System specifications: 3 kW system with 7 panels of 430 W each, 3 kW grid-tie inverter, ACDB/DCDB, mounting structure, and cabling. Gross cost: Rs 1,65,000.

CFA calculation:

• PM Surya Ghar CFA: Rs 30,000 x 2 kW + Rs 18,000 x 1 kW = Rs 78,000
• No Gujarat state top-up is counted: MGVCL’s PM Surya Ghar subsidy sheet lists only the central amount

Net investment: Rs 1,65,000 - Rs 78,000 = Rs 87,000

Generation and savings: The 3 kW system generates approximately 450 kWh per month in Ahmedabad. At Gujarat residential tariff of Rs 5.50 per kWh (blended rate), monthly savings are Rs 2,475. Annual savings: Rs 29,700.

Payback period: Rs 87,000 / Rs 29,700 = 2.9 years

25-year return: Rs 29,700 × 25 years = Rs 7,42,500 in cumulative savings, against a net investment of Rs 87,000. This is about 8.5x the investment, before any tariff escalation.

CFA timeline: The Patels register on the PM Surya Ghar portal on January 10. DISCOM feasibility is approved on January 20. Heaven Green Energy completes installation on February 5. Net metering is installed on February 12. The DISCOM inspection is completed and approved on February 18, which activates the e-token. The Patels redeem it on the portal, and the CFA of Rs 78,000 is processed within the 15-day window that follows DISCOM approval.

Without CFA, the payback would be 5.6 years (Rs 1,65,000 / Rs 29,700). The Rs 78,000 CFA cuts it nearly in half.

Technical Specifications / Benchmarks

Benefits / Advantages

• Direct cost reduction: CFA can cut the upfront cost of a small residential system by close to half (about 47% in the 3 kW example above), making systems affordable for middle-income households and small farmers who would otherwise delay adoption.

• Direct transfer: The consumer redeems the e-token on the portal and the CFA goes to their own bank or loan account, without passing through the vendor.

• Payback acceleration: CFA reduces residential solar payback from 5-6 years to 2.5-3.5 years, dramatically improving return on investment and household cash flow.

• Quality enforcement: CFA eligibility requires DCR, ALMM-listed modules and a vendor registered on the PM Surya Ghar national portal, using inverters meeting current BIS and IEC compliance standards. This prevents substandard installations and protects consumers from fly-by-night operators.

• National portal integration: The unified PM Surya Ghar portal streamlines application, tracking, and disbursement. Beneficiaries can monitor their CFA status in real time.

• State synergy: Where a state has notified its own top-up, it can stack with central CFA. Check the state’s own notification; Gujarat’s DISCOM subsidy sheet lists only the central amount.

• Rural electrification: PM KUSUM CFA brings solar pumps to farmers who lack reliable grid power, replacing diesel dependence with clean, free solar energy.

• Employment generation: CFA-driven installations support direct jobs in manufacturing, installation, and O&M, plus indirect employment in logistics and financing.

Limitations / Drawbacks

• Cap on maximum CFA: The PM Surya Ghar CFA caps at Rs 78,000 regardless of system size beyond 3 kW. A 10 kW system receives the same CFA as a 3 kW system, reducing the subsidy percentage for larger installations.

• ALMM restriction: Only ALMM-listed modules qualify for CFA. This excludes some high-efficiency imported panels, limiting consumer choice. The ALMM list is also periodically updated, creating uncertainty; Heaven Designs’ breakdown of how the ALMM list affects a solar BOQ is a useful reference for procurement teams.

• Documentation burden: The CFA process requires consumer and bank account details with proof, system details, geo-tagged photographs, and the DISCOM inspection and metering agreement. Mismatches cause delays.

• Upfront float: The CFA is only released after DISCOM inspection and e-token redemption (processed within 15 days of DISCOM approval), so beneficiaries must fund the full cost first. A portal-linked loan reduces this, because the CFA then goes to the loan account.

• Vendor availability: Only vendors registered on the PM Surya Ghar national portal can install CFA-eligible systems. In remote areas, few registered vendors may serve your DISCOM.

• No CFA for OPEX/RESCO: Consumers who prefer a zero-upfront OPEX model delivered through a RESCO arrangement (where a developer owns the system and sells power) cannot claim CFA directly. The subsidy flows to the developer, not the consumer.

• One-time CFA: CFA is available only once per installation. A system that is later shifted or relocated to a new location is not eligible for CFA again.

Comparison Section

Applications

Residential rooftop solar: CFA under PM Surya Ghar is the primary driver of India’s residential solar market. A 3 kW home solar system in Gujarat with Rs 78,000 CFA delivers payback of about 3 years. Heaven Green Energy has installed over 2,000 residential systems under this scheme across Ahmedabad, Surat, Vadodara, and Rajkot.

Agricultural solar pumps: PM KUSUM Component B CFA has been used to replace diesel pumps with solar pumps, with 30% central support plus at least 30% from the state. The scheme period ended on 31 March 2026; only projects already sanctioned may complete, and new applications depend on PM-KUSUM 2.0.

Commercial and industrial rooftop: There is no central CFA for commercial or industrial rooftops. Tax-paying businesses rely on accelerated depreciation instead.

Ground-mount distributed solar: PM KUSUM Component A supported 500 kW to 2 MW solar plants on farmland. Instead of a capital CFA, the DISCOM bought the power at a pre-fixed tariff and received a procurement-based incentive from MNRE. Where a developer set up the plant, the farmer earned lease rent for the land.

Industry Standards & Regulations

• MNRE PM Surya Ghar Muft Bijli Yojana Operational Guidelines, 7 June 2024: Defines residential CFA slabs (Rs 30,000/kW for the first 2 kW, Rs 18,000 for the 3rd kW, capped at Rs 78,000), eligibility, equipment standards, the e-token release process and the 15-day processing rule.

• MNRE Comprehensive Guidelines for Implementation of PM-KUSUM, 17 January 2024: Covers Component A (decentralised plants), Component B (standalone pumps), and Component C (grid-connected pump solarisation) with CFA structures and farmer contribution ratios.

• MNRE ALMM Order and DCR rule: Only domestically manufactured cells and modules qualify for PM Surya Ghar CFA, and modules must be on the Approved List of Models and Manufacturers. The ALMM list is updated periodically and published on the MNRE website. Heaven Designs’ MNRE and DCR compliance guide walks through how these module-sourcing rules interact with domestic content requirements during project design.

• Vendor registration (PM Surya Ghar guidelines, clause 7): The scheme runs only through vendors registered on the National Portal, via the state DISCOM or agency or the National Programme Implementation Agency. This replaced the tender-based DISCOM empanelment of the Phase-II programme.

• State and DISCOM circulars: State agencies and DISCOMs issue implementation circulars on documentation and inspection, and on any state top-up where one has actually been notified.

• DISCOM Net Metering Regulations: State-specific regulations governing the net-metering process that is a prerequisite for CFA disbursement.

India-Specific Context

India’s CFA ecosystem has evolved significantly since the early rooftop solar programmes of 2010-2015. The earlier percentage-based CFA models, ending with Phase-II’s 40% and 20% residential slabs, were replaced in 2024 by the more targeted per-kW PM Surya Ghar structure, which offers higher per-kW subsidies for smaller systems to maximise household participation. For a deeper technical walkthrough of the national scheme mechanics, QBits Energy’s PM Surya Ghar Yojana guide is a useful complementary reference.

Gujarat has been a CFA success story. Its four state DISCOMs (UGVCL, MGVCL, PGVCL, DGVCL), together with Torrent Power in Ahmedabad, Gandhinagar and parts of Surat city, handle the net-metering connections for rooftop applications. For PM Surya Ghar, MGVCL’s subsidy sheet lists only the central CFA, so Gujarat homeowners should not count on a state top-up; see state versus central subsidy for how layering works where states do offer one. The Gujarat Energy Development Agency (GEDA) is the state’s renewable energy agency.

The PM Surya Ghar portal, launched in 2024, has addressed a major pain point of earlier schemes: opacity. Beneficiaries can now track their application status, DISCOM approval, inspection scheduling, and CFA disbursement in real time. The portal also ties each claim to a DISCOM consumer number, and a system can receive CFA only once.

However, challenges remain. ALMM restrictions have caused module supply shortages during peak demand periods, delaying installations. PM Surya Ghar CFA stops growing at 3 kW, so larger homes get the same Rs 78,000, and small commercial entities get no CFA at all. Registered vendors are also thinner on the ground in remote districts.

Heaven Green Energy addresses these gaps through a statewide service network, with Gujarat offices in Surat, Ahmedabad, Vadodara and Junagadh and a team that also covers Rajkot and Gandhinagar. Our in-house CFA processing team checks documentation before submission to reduce disbursement delays.

Future Trends

Three policy trends will reshape CFA in the coming years.

Battery storage: PM Surya Ghar CFA is calculated on the solar capacity, not on batteries. Behind-the-meter and battery hybrid systems can qualify subject to the state regulator’s approval, but any CFA for the battery itself would need a new MNRE notification.

OPEX model CFA restructuring: As OPEX/RESCO models grow in popularity (especially for commercial rooftops), a structure where the subsidy reaches the consumer as a tariff discount rather than an upfront capital grant would make CFA accessible to consumers who prefer zero-down payment arrangements. Any such change would need an MNRE notification.

Digital integration and verification: The PM Surya Ghar portal already takes geo-tagged photographs of each installation. Remote verification could shorten the process further, but today the guidelines require the DISCOM to physically inspect the system before CFA is processed.

For consumers, the key takeaway is that PM Surya Ghar is approved for implementation till FY 2026-27 and is fund-limited (capped at 1 crore active applications). What follows depends on new government decisions, so homeowners who install while the scheme runs get today’s CFA rates.

Common Mistakes & Misconceptions

• Choosing an unregistered vendor or non-DCR modules: CFA is denied for these installations. Always verify that the vendor is registered on the PM Surya Ghar portal for your DISCOM, and check module ALMM and DCR status, before signing contracts.

• Mismatching documentation: The bank account on the portal must be in the applicant’s name, with a cancelled cheque or passbook as proof, and should match the electricity connection name. Spelling variations can trigger manual review.

• Skipping the national portal: Informal installations through unregistered vendors void CFA eligibility. The portal registration is mandatory, not optional.

• Forgetting to redeem the e-token: The CFA is only released after you redeem the activated e-token on the portal; it is then processed within 15 days of DISCOM approval. If you took a portal-linked loan, it goes to the loan account first.

• Counting on an unverified state top-up: Only budget for a state subsidy if the state or DISCOM has notified it. Gujarat’s DISCOM subsidy sheet for PM Surya Ghar lists only the central amount.

• Assuming CFA covers all system sizes equally: The Rs 78,000 cap applies regardless of size beyond 3 kW. A 10 kW system receives the same CFA as a 3 kW system, making the subsidy percentage much smaller for large installations.

• Assuming a moved system qualifies again: CFA is available only once per installation. If the system is shifted or relocated to a new location, it cannot claim CFA again.

• Expecting CFA for rented properties: The application runs on the electricity consumer number, and the CFA goes to that consumer’s own bank account. A tenant whose connection is in the landlord’s name cannot apply in their own name.

Key Takeaways

• Central Financial Assistance (CFA) is the direct subsidy provided by the central government through MNRE for solar installations under specific schemes. Under PM Surya Ghar it is released when the consumer redeems an e-token on the National Portal.

• PM Surya Ghar provides residential CFA of Rs 30,000/kW for the first 2 kW and Rs 18,000 for the 3rd kW, capped at Rs 78,000 for 3 kW and above. PM KUSUM Component B provided 30% central CFA for standalone solar pumps until its scheme period ended on 31 March 2026.

• Some states add their own top-ups, but only count one the state has notified. Gujarat’s DISCOM subsidy sheet lists only the central amount.

• CFA eligibility requires DCR, ALMM-listed modules, a vendor registered on the PM Surya Ghar national portal, and DISCOM inspection. Non-compliant installations are ineligible for subsidy.

• The CFA is processed within 15 days of DISCOM approval, once the consumer redeems the activated e-token, and goes to the bank account on the portal (or the loan account first if financed).

• Documentation accuracy is critical. Mismatched names, missing documents or incorrect bank details commonly delay CFA.

• CFA reduces residential solar payback from 5-6 years to 2.5-3.5 years, making solar accessible to middle-income households who would otherwise defer adoption.

• Possible future changes include OPEX model restructuring and more digital verification; any battery subsidy would need a new MNRE notification.

Frequently Asked Questions

What is Central Financial Assistance? CFA is the direct subsidy provided by the central government (through MNRE) for solar installations under specific schemes. Under PM Surya Ghar it is released through an e-token that the consumer redeems on the National Portal after the DISCOM has inspected the system.

What is PM Surya Ghar CFA? Under PM Surya Ghar Muft Bijli Yojana, residential CFA is Rs 30,000/kW for the first 2 kW and Rs 18,000 for the 3rd kW, so Rs 30,000 for 1 kW, Rs 60,000 for 2 kW and a maximum of Rs 78,000 for any system of 3 kW or larger.

What is PM KUSUM CFA? Under PM KUSUM Component B (standalone solar pumps), central CFA was 30% of the benchmark or tender cost, whichever is lower (50% in North-Eastern, hill and island states), with the state contributing at least 30%. The scheme period ended on 31 March 2026; new applications depend on PM-KUSUM 2.0, which MNRE described as being in the proposal stage.

Who is eligible for CFA? Depends on the scheme. PM Surya Ghar: residential consumers with electricity connection in their name. PM KUSUM: farmers with land ownership and existing diesel pump or grid pump for solarisation. Specific eligibility per scheme guidelines.

How is CFA disbursed? An e-token is generated when you apply on the National Portal. After the documents are uploaded and the DISCOM has inspected the system, the e-token is activated for the eligible amount and you redeem it on the portal. The CFA then goes to the bank account you submitted on the portal (with a cancelled cheque or passbook as proof), or to your loan account first if the system is financed.

Can CFA be combined with state subsidy? Only where a state has notified its own top-up. Check the state government’s or DISCOM’s own notification before counting on one. In Gujarat, MGVCL’s PM Surya Ghar subsidy sheet lists only the central amount.

Does CFA require specific equipment? Yes. Modules and cells must be domestically manufactured (DCR), modules must be ALMM-listed, and the system must meet the scheme’s minimum technical specifications. The installer must be a vendor registered on the PM Surya Ghar national portal.

What if the installation fails inspection? The e-token is not activated until the installation passes DISCOM inspection. The registered vendor must rectify any system or component defect that stops commissioning or CFA release. Once the DISCOM approves, the CFA is processed within 15 days of that approval.

Is CFA taxable? Generally treated as a capital subsidy reducing the cost basis of the asset for depreciation. For residential consumers without business income, tax treatment is less concerning. For business consumers, consult a chartered accountant.

Can CFA be refunded if I uninstall? CFA is available only once per installation, and a system that is shifted or relocated to a new location is not eligible for CFA again. Check the DISCOM agreement and the scheme terms on the National Portal before dismantling or moving a subsidised system.

Is CFA available for OPEX/RESCO solar? For PM Surya Ghar (residential), the CFA is for the consumer’s installed system, typically CAPEX. OPEX/RESCO arrangements where the developer owns the asset have different mechanisms; CFA may not apply directly to the consumer.

How long does CFA disbursement take? MNRE’s guidelines say the CFA is processed within 15 days of approval by the DISCOM. The clock effectively starts once the DISCOM has inspected the system and you have redeemed the activated e-token on the portal.
