PM Surya Ghar RWA Subsidy 2026: Eligibility, 500 kW Limit and Application Guide

Group Housing and Common-Facility Solar Guide

PM Surya Ghar RWA Subsidy 2026

Understand CFA for Resident Welfare Associations and Group Housing Societies, including the ₹18,000-per-kWp rate, 500-kWp ceiling, three-kWp-per-house calculation, individual rooftop adjustment, common-area consumption, EV charging, documents, approvals, metering and society-level governance.

Last Updated: July 25, 2026

Quick Answer: A Group Housing Society, Resident Welfare Association or similar residential body can receive Central Financial Assistance for a grid-connected rooftop solar plant serving common facilities, including EV charging. Under the operational guideline, the CFA rate is ₹18,000 per kWp in ordinary States and UTs and ₹19,800 per kWp in special-category States and UTs. Eligible supported capacity is restricted to the lowest of: the actual eligible common-facility plant capacity, three kWp multiplied by the number of houses, and 500 kWp—after accounting for individual rooftop plants within the GHS or RWA because the upper limit is inclusive of those individual systems. The common-facility connection must remain dedicated to common facilities and should not be used to supply electricity directly to individual residences. The association must also follow the National Portal, registered-vendor, DCR-module, DISCOM inspection, metering, commissioning and bank-account process.
Do not calculate RWA subsidy as ₹18,000 multiplied by the full quoted plant size automatically. The eligible kWp can be lower because of the three-kWp-per-house rule, the 500-kWp cap and individual rooftop capacity already present within the society.
Common-facility solar is not a private electricity-supply network for flats. The scheme guideline says the eligible GHS/RWA connection should be dedicated to common facilities and not used to provide electricity supply to residential consumers within the society.

Who Can Apply for PM Surya Ghar RWA Subsidy?

Group Housing Society

A legally or operationally recognised group-housing residential body using a common electricity connection for shared facilities.

Resident Welfare Association

A residential association managing shared services, common loads and the common rooftop or another eligible common installation space.

Similar Residential Body

Another eligible residential-management entity may qualify when the National Portal and DISCOM accept its constitution and common-facility connection.

Common-Facility Connection

The grid-connected solar plant must be tagged to an eligible connection dedicated to common facilities.

  • The project belongs to the residential segment.
  • The applicant body manages an eligible common connection.
  • The solar plant is grid connected.
  • The generation serves common facilities, including approved EV-charging use.
  • The project uses a National Portal registered vendor.
  • The installation uses DCR-compliant modules made from domestic cells.
  • The plant follows the applicable DISCOM and State metering rules.
  • The association has valid authority to use the roof and enter the project agreement.

PM Surya Ghar RWA CFA Rates in 2026

Residential segment Ordinary State/UT CFA Special-category State/UT CFA Maximum supported capacity rule
GHS/RWA common facilities, including EV charging ₹18,000 per kWp ₹19,800 per kWp Up to 500 kWp and up to 3 kWp per house, inclusive of individual rooftop plants
Ordinary State/UT formula:
Eligible RWA capacity × ₹18,000

Special-category formula:
Eligible RWA capacity × ₹19,800

Special-category locations listed in the operational guideline include Uttarakhand, Himachal Pradesh, Jammu and Kashmir, Ladakh, North-Eastern States including Sikkim, Andaman and Nicobar Islands, and Lakshadweep.

State subsidy can be additional but is not automatic. A State or UT may supplement Central CFA, subject to its current policy and National Portal integration. Check current local notifications before budgeting.

How the 500 kWp and 3 kWp per House Limit Works

Step 1: House-based ceiling Number of houses × 3 kWp
Step 2: Overall ceiling Maximum 500 kWp
Step 3: Individual plants Account for rooftop capacity installed by residents
Step 4: Actual plant CFA applies only to eligible installed capacity
Planning formula:

Society ceiling before individual adjustment = lower of (number of houses × 3 kWp) or 500 kWp

Remaining common-facility ceiling = society ceiling − individual rooftop capacity counted within the GHS/RWA limit

Eligible RWA capacity = lower of actual eligible common plant capacity or remaining common-facility ceiling
Use the portal and DISCOM record for the final calculation. The formula is a practical reading of the operational guideline, which states that the upper limit of CFA-supported RWA capacity is inclusive of individual rooftop plants installed by residents.

Enter installed individual capacity that must be included in the overall RWA limit. Confirm the final count with the portal/DISCOM.
Estimated eligible common capacity: 100 kWp
3 kWp per house ceiling 150 kWp
Remaining ceiling 150 kWp
Estimated Central CFA ₹18,00,000

RWA Subsidy Calculation Examples

Scenario House-based ceiling Eligible common capacity Ordinary-State CFA
20 houses, proposed 100 kWp, no individual systems 20 × 3 = 60 kWp 60 kWp 60 × ₹18,000 = ₹10,80,000
50 houses, proposed 100 kWp, no individual systems 50 × 3 = 150 kWp 100 kWp 100 × ₹18,000 = ₹18,00,000
100 houses, proposed 250 kWp, 30 kWp individual systems 100 × 3 = 300 kWp Lower of 250 or 270 = 250 kWp 250 × ₹18,000 = ₹45,00,000
100 houses, proposed 300 kWp, 80 kWp individual systems 300 kWp Lower of 300 or 220 = 220 kWp 220 × ₹18,000 = ₹39,60,000
300 houses, proposed 600 kWp, no individual systems 900 kWp, capped at 500 500 kWp 500 × ₹18,000 = ₹90,00,000
The first two examples follow the official guideline illustrations. The later examples demonstrate the inclusive-limit formula for planning. Final eligibility depends on the National Portal, documented individual capacity and concerned DISCOM verification.

How Individual Rooftop Plants Affect the RWA Limit

The operational guideline states that the upper limit of CFA-supported RTS capacity for a GHS/RWA is inclusive of individual rooftop plants installed by individual residents within the society. This prevents the association and residents from treating the three-kWp-per-house ceiling as two separate full entitlements.

  • Create a flat-wise list of existing individual rooftop systems.
  • Record application ID, installed DC capacity and CFA status where available.
  • Confirm whether planned resident systems are already approved or under installation.
  • Ask the DISCOM how individual capacity will be counted in the RWA application.
  • Freeze the common-plant design only after the remaining ceiling is confirmed.
  • Update the society register when an individual resident later installs solar.
Do not hide individual rooftop systems from the RWA calculation. Inspection and consumer-account records can reveal capacity already installed within the housing society.

What Can Common-Facility Solar Supply?

The official guideline expressly covers common facilities, including EV charging. It does not publish one exhaustive national list of every common load. The following are practical examples that should be verified against the society’s connection, State regulation and DISCOM approval.

Lifts and Escalators

Common vertical-transport loads supplied through the society connection.

Water Pumps

Borewell, transfer, pressure and overhead-tank pumping for shared services.

Common Lighting

Corridors, staircases, parking, roads, gates and landscape lighting.

EV Charging

Approved charging loads connected through the common-facility arrangement.

Security and Access

Gate systems, cameras, intercom, access control and security rooms.

Clubhouse or Community Areas

Shared facilities where the electricity is billed through the eligible common connection.

Wastewater or Treatment Loads

STP, water treatment or waste-management equipment serving the complex.

Fire and Emergency Systems

Eligible common auxiliary loads, subject to safety and backup requirements.

Other Shared Loads

Only after verifying the connection, tariff, metering and society authority.

Solar does not replace emergency power design. Standard on-grid solar usually shuts down during a grid outage. Lifts, fire pumps and critical systems need their legally required backup and safety arrangements.

What the RWA Common Connection Should Not Be Used For

  • Direct electricity supply to individual flats through an unapproved private distribution arrangement
  • Commercial or industrial loads unrelated to the eligible residential common facilities
  • A fully off-grid installation claimed as a grid-connected common project
  • Inflated house count or common-load capacity
  • Non-DCR modules when Central CFA is claimed
  • Mixing individual and common capacity without disclosing the overall ceiling
  • Using another society’s consumer connection or photographs
  • Charging residents an undisclosed premium while presenting the project as fully government funded

Compare grid architectures in the on-grid versus off-grid solar guide .

RWA Common Subsidy vs Individual Household Subsidy

Feature Individual household GHS/RWA common facilities
Beneficiary Eligible residential consumer Eligible society/association common connection
Purpose Household electricity connection Common facilities, including EV charging
CFA rate ₹30,000/kWp first 2 kWp, ₹18,000 for next 1 kWp in ordinary locations ₹18,000/kWp in ordinary locations
Maximum supported capacity No additional household CFA beyond 3 kWp Up to 500 kWp and 3 kWp per house, inclusive of individual plants
Electricity use Tagged household connection Dedicated common-facility connection
Decision process Individual consumer Association authority, resolution, members and common-property rules
Bank account Concerned consumer Eligible beneficiary entity/account accepted in the workflow

The household CFA structure is explained in the PM Surya Ghar subsidy guide .

Society Resolution, Member Consent and Governance

The central CFA guideline establishes subsidy eligibility but does not replace the association’s own bye-laws, apartment law, cooperative-society law, title documents or meeting rules. The RWA should confirm who is authorised to use the common roof, borrow or spend funds, sign the vendor agreement, operate the bank account and allocate savings.

  • Valid association registration and governing documents
  • Authority of committee or board
  • Meeting notice and quorum
  • Resolution approving capacity, budget and funding
  • Authority to use common roof and electrical connection
  • Member disclosure of roof access and maintenance implications
  • Conflict-of-interest declaration for vendor selection
  • Authorised signatories for portal, bank and contract
  • Resident contribution and refund rules
  • Allocation of electricity savings
  • EV charging pricing and access rules
  • Future individual rooftop application policy
Do not use “majority approved” as a substitute for the actual bye-law requirement. Required notice, quorum and voting threshold can differ by entity and State law.

Audit the Common Electricity Load Before Choosing Capacity

Load category Data to collect Design relevance
Lifts Rated power, number, operating hours and starting behaviour Daytime energy use and demand pattern
Water pumps Motor ratings, schedules and seasonal operation Can be shifted toward solar hours where operationally safe
Lighting Fixture count, wattage and day/night use Night load may not directly consume daytime solar without net accounting
STP and treatment Motor, blower and pump schedules Often provides stable daytime common load
EV charging Charger rating, vehicles, simultaneous demand and charging window Future demand can materially change optimal plant size
Clubhouse and offices Air conditioning, appliances and operating schedule Variable occupancy and seasonal use
Existing DG or backup Essential circuits and changeover arrangement Solar interconnection must not defeat emergency design
  • Collect at least 12 months of common-meter bills.
  • Record monthly units, maximum demand and tariff.
  • Separate common connection from individual flat bills.
  • Identify daytime and night-time consumption.
  • Include approved future EV and facility loads.
  • Check export compensation under current State regulation.

How to Choose the RWA Solar Plant Size

The subsidy ceiling is not automatically the economically ideal plant size. Compare the allowed capacity with roof area, shade, common annual consumption, daytime load, export tariff, sanctioned load, transformer and interconnection conditions.

Planning capacity is the lowest practical result of:

Scheme-supported ceiling
Common-load energy requirement
Suitable shadow-free roof area
DISCOM and metering approval
Budget and financing capacity
Vendor’s safe technical design

Estimate roof space with the solar-panel rooftop-area guide and understand capacity selection through the solar system-size guide .

Do not install 500 kWp merely because it is the national cap. Many societies have a lower house-based ceiling, smaller roof, lower common consumption or a different DISCOM-approved capacity.

Common Roof Rights, Access and Competing Uses

  • Confirm that the roof or elevated space is common property or validly controlled by the association.
  • Map water tanks, fire access, antennas, ducts and maintenance routes.
  • Preserve drainage and waterproofing.
  • Check structural load and wind design.
  • Reserve access for façade, lift-room and building maintenance.
  • Record whether top-floor residents have any exclusive or licensed rights.
  • Plan safe fire and emergency access.
  • Define responsibility for roof leakage or structural damage.
  • Document future building work and module-removal costs.
Use a roof plan, not only a square-metre estimate. A large roof can still have limited usable area because of shade, equipment, setbacks, walkways and structural zones.

The exact portal list can differ by State and entity type. The following file should be prepared before vendor selection and final submission.

Association Documents

  • Registration certificate
  • Bye-laws or constitution
  • PAN and authorised signatory

PM Surya Ghar RWA Application Process

  1. Confirm the eligible association entity and common electricity connection.
  2. Verify the total house count and individual rooftop capacity.
  3. Pass the required society resolution and authorise signatories.
  4. Audit common loads, roof, structure and interconnection.
  5. Register or apply through the current National Portal RWA/GHS workflow.
  6. Record the unique application ID and consumer account number.
  7. Complete feasibility, load or DISCOM requirements under the current process.
  8. Compare National Portal registered vendors and obtain detailed quotations.
  9. Freeze eligible capacity, DCR modules, inverter, structure, metering and price.
  10. Sign the vendor agreement and complete financing arrangements.
  11. Install the system and carry out technical and safety tests.
  12. Upload actual system details, documents and geo-tagged photographs.
  13. Complete DISCOM inspection, agreement, meter and commissioning.
  14. Confirm eligible CFA and complete the token or payment workflow.
  15. Preserve handover, warranties, CMC and monitoring access.

The basic portal sequence is explained in the PM Surya Ghar apply-online guide .

How an RWA Should Select a Solar Vendor

  • Verify current National Portal registration and operating area.
  • Ask for comparable RWA/GHS project references.
  • Demand an itemised GST-inclusive quotation.
  • List exact DCR module manufacturer and model.
  • List inverter model, phase, MPPT and monitoring.
  • Define structure, waterproofing and roof-restoration scope.
  • Define DISCOM, meter, EV-charging and commissioning support.
  • Define five-year CMC and preventive visits.
  • Use milestone payments with retention until commissioning and handover.
  • Require drawings, test reports, serials and administrator monitoring access.
  • Disclose committee conflicts of interest.
  • Compare lifecycle cost, not only headline price.

Use the registered-vendor guide and follow the complete solar-installation process .

Do not award a large society project on a one-page quotation. Capacity ceiling, individual systems, structural work, common metering, EV charging, warranties and commissioning must be defined.

DCR Modules, Inverter and Technical Eligibility

The RWA project must use domestically manufactured modules made from domestically manufactured cells to receive CFA. The physical module model, serial register, invoice, DCR evidence and portal entry should match.

  • Exact module manufacturer, model, wattage and quantity
  • Domestic-cell and domestic-module evidence
  • Applicable ALMM and technical records
  • Complete module serial register
  • Inverter model, AC rating and phase
  • String voltage, current and MPPT compatibility
  • Anti-islanding and grid-protection evidence
  • Structure, cable, surge protection and earthing design
  • Monitoring and generation-data access

Verify modules through the DCR module guide and inverter design through the inverter-selection guide .

A large array magnifies a small documentation problem. One undocumented batch, wrong model or serial mismatch can create a substantial CFA and inspection dispute.

Metering and Electricity Accounting for Common Solar

The metering arrangement depends on current State regulations and the concerned DISCOM. Net metering, net billing, gross metering, group net metering, virtual net metering or another approved mechanism should not be assumed without written confirmation.

  • Identify the eligible common consumer account number.
  • Confirm sanctioned load, phase and contract demand.
  • Confirm the approved solar and inverter capacity.
  • Confirm meter type, location and ownership.
  • Confirm how imported and exported units are settled.
  • Confirm billing treatment for common facilities and EV charging.
  • Confirm transformer and protection requirements.
  • Sign the applicable metering or grid agreement.
  • Check the first bills for correct import/export and tariff treatment.

Follow the PM Surya Ghar net-meter guide .

Virtual or group net metering is regulatory, not automatic. Use it only where the State regulator and DISCOM permit it and the approved project structure matches the scheme’s common-facility requirement.

Using RWA Solar for EV Charging

EV charging is expressly included within the common-facility category. The society still needs a technical, tariff, fire-safety and user-charging policy.

Capacity Planning

Number of chargers, rating, diversity, vehicle growth and daytime charging.

Electrical Design

Sanctioned load, distribution board, protection, earthing, cable route and meter.

Commercial Policy

Energy charge, parking fee, maintenance, idle fee and non-resident access.

Safety and Fire

Approved equipment, emergency isolation, signage, ventilation and local rules.

  • Prefer solar-hour charging where practical.
  • Use smart load management to avoid simultaneous peak demand.
  • Separate solar generation accounting from charger-user billing.
  • Record whether charging revenue or cost recovery is permitted under local rules.
  • Plan future charger expansion without oversizing the initial solar solely for subsidy.

DISCOM Inspection of an RWA Solar Plant

  • Association and common consumer details
  • Actual module DC capacity
  • House count and CFA-supported capacity
  • Individual rooftop capacity within the society
  • DCR modules and serials
  • Inverter model, phase and protection
  • Structure, roof access and clearances
  • DC and AC cabling
  • Earthing, surge and lightning protection
  • Common-facility point of connection
  • Meter and agreement
  • Invoice, PCR, photographs and test reports

Prepare through the complete DISCOM inspection guide .

Do not present one capacity to members and another to the DISCOM. Resolution, contract, invoice, physical plant, inspection and CFA calculation should match.

RWA Bank Account and CFA Payment

The beneficiary bank account must be accepted in the National Portal workflow and belong to the concerned applicant entity or consumer record. The association should avoid using an office-bearer’s personal bank account for project CFA or resident contributions.

  • Bank account in the eligible association/entity name
  • PAN and KYC consistency
  • Authorised signatory resolution
  • Correct account number and current IFSC
  • Cancelled cheque, statement or passbook evidence
  • Active account capable of receiving transfer
  • Dual-signature or committee controls where required
  • Separate project ledger for resident contributions and vendor payments

Track release through the PM Surya Ghar subsidy-payment status guide .

How Residents Can Share the Project Cost

Central CFA does not necessarily cover the full project price. The society must decide the remaining contribution under its bye-laws and resolution.

Contribution method Advantage Governance concern
Equal amount per flat Simple administration May be challenged where unit sizes or voting rights differ
Area-based contribution May align with existing maintenance formula Must follow bye-laws and approved resolution
Society reserve fund No immediate special collection Check permitted fund use and future reserve adequacy
Bank or institutional loan Spreads capital cost Authority to borrow, security, repayment and CFA linkage
EV-charging or facility revenue Can support operating cost Tariff, tax, policy and usage uncertainty
Mixed funding Balances reserve, contribution and loan Needs transparent accounting and priority of payments
Do not collect the gross project price without disclosing expected CFA. The resolution and contribution notice should explain subsidy assumptions, shortfall risk, payment milestones and refund treatment.

Calculate Common-Area Solar Savings Correctly

Annual gross benefit may include:
Self-consumed solar units × avoided common tariff
+ exported units × applicable credit rate
− annual maintenance, insurance, meter and finance costs
  • Use the common meter’s tariff, not an individual domestic tariff.
  • Separate energy charge, demand charge and fixed charge.
  • Check whether solar reduces demand charges under local billing rules.
  • Use realistic generation and degradation assumptions.
  • Include inverter replacement and post-CMC maintenance reserve.
  • Model EV charging separately from ordinary common consumption.
  • Compare actual bills every month after commissioning.

Adapt the method in the PM Surya Ghar savings calculator .

Do not promise every resident a fixed monthly cash saving. The plant reduces the common account according to generation, consumption, metering and tariff. How that benefit reaches members depends on society accounting.

Five-Year CMC, Warranty and Society Maintenance

Registered vendors must provide five years of repair and maintenance from commissioning under the scheme CMC. A large RWA project should turn that obligation into measurable service levels.

  • Preventive-maintenance frequency
  • Cleaning labour, water and access
  • Fault response and escalation time
  • Monitoring administrator access
  • Module and inverter warranty documents
  • String and inverter performance reports
  • Structure, roof and corrosion checks
  • Earthing and protection testing
  • EV-charger coordination where included
  • Replacement serial and portal records
  • Year-five condition audit
  • Post-CMC maintenance budget

Follow the rooftop solar maintenance and warranty guide .

Existing Solar, Prior Subsidy and Later Expansion

The guidelines address additional CFA for a previously subsidised rooftop installation only for remaining eligible capacity. For an RWA, expansion planning must also respect the 500-kWp, three-kWp-per-house and individual-rooftop-inclusive limits.

  1. Record all existing common and individual solar capacity.
  2. Record the scheme and CFA already received.
  3. Confirm remaining eligible capacity with the portal and DISCOM.
  4. Audit roof, inverter and meter capacity.
  5. Use compliant new modules and equipment.
  6. Keep old and new project documents separate but linked.
  7. Do not claim fresh CFA merely because an old plant was relocated.
Capacity expansion is not always subsidy expansion. The society may install additional technically approved capacity beyond the CFA-supported portion, but only eligible capacity receives Central assistance.
Track every RWA application stage: Use the PM Surya Ghar application-status guide to identify whether the case is pending with the association, vendor, DISCOM, meter provider, portal or bank.

Application Correction, Approval Delay and Grievance

House Count or Capacity Error

Correct the source register, capacity calculation and portal records together.

Vendor or Equipment Error

Use the existing application’s correction or vendor-change route.

Inspection Rejection

Correct the physical plant and documentary evidence before re-inspection.

Field Locked or Delayed

Raise a grievance under the same application with exact evidence and requested action.

Use the application-correction guide , approval-delay guide , rejection guide and vendor-change guide .

Do not open a duplicate RWA application merely to correct a field. Preserve the existing application ID and use the official correction or grievance route unless the authority instructs a fresh submission.

Frequently Asked Questions

Can an RWA get PM Surya Ghar subsidy?

Yes. Eligible GHS/RWA projects can receive CFA for grid-connected solar serving common facilities, including EV charging.

What is the RWA subsidy rate?

₹18,000 per kWp in ordinary States and UTs and ₹19,800 per kWp in listed special-category States and UTs.

What is the maximum RWA capacity eligible for CFA?

Up to 500 kWp, also limited to three kWp per house and inclusive of individual rooftop plants within the society.

How is the three-kWp-per-house limit calculated?

Multiply the verified number of houses by three kWp, apply the 500-kWp cap and account for individual rooftop capacity within the overall limit.

Can a 20-flat society claim CFA on a 100-kWp common plant?

The official illustration limits supported capacity to 60 kWp, producing ₹10,80,000 CFA at ₹18,000 per kWp.

Can a 50-flat society claim CFA on a 100-kWp plant?

The official illustration supports the full 100 kWp because the house-based ceiling is 150 kWp, resulting in ₹18,00,000 CFA at the ordinary rate.

Do individual rooftop systems reduce the RWA ceiling?

The guideline says the upper limit is inclusive of individual rooftop plants installed by residents within the GHS/RWA.

Can common solar supply electricity directly to every flat?

The eligible connection should be dedicated to common facilities and should not provide direct electricity supply to residential consumers within the RWA.

Is EV charging eligible?

Yes. EV charging is expressly included as a common facility under the RWA/GHS CFA category.

Are lifts and water pumps eligible common loads?

They are practical common-facility examples when supplied through the eligible common connection, but confirm the project with the DISCOM and current portal.

Does the society need member approval?

Follow the association’s bye-laws and applicable law for notice, quorum, voting, roof use, borrowing and spending authority.

Can an RWA use any solar vendor?

A CFA-claiming project must use a vendor registered on the National Portal.

Are DCR modules compulsory?

Yes. Modules must be domestically manufactured from domestically manufactured cells for CFA eligibility.

Does inverter capacity determine RWA subsidy?

No. CFA is based on eligible module DC capacity, subject to the RWA capacity ceilings.

Can an RWA install more than the CFA-supported capacity?

Additional technically and regulatorily approved capacity may be possible, but the portion above the eligible ceiling does not receive Central CFA.

Can an RWA get a State subsidy too?

A State or UT may provide additional support, but it depends on the current local scheme and National Portal integration.

Which meter is used for RWA solar?

The meter and settlement mechanism depend on State regulations and DISCOM approval. Do not assume net or virtual net metering without confirmation.

Who receives the CFA?

The payment must follow the accepted beneficiary bank or linked-loan account workflow in the National Portal.

Does the vendor provide maintenance?

Registered vendors must provide five years of free repair and maintenance under the scheme CMC from commissioning.

How should the society calculate savings?

Use common-meter avoided tariff, export credit, demand-charge treatment, generation, degradation, maintenance, insurance and finance cost.

Can the RWA change its vendor?

It may be possible, but portal stage, agreement, payment, materials and completed work must be handled through the existing application and proper transfer records.

What if the application is delayed?

Identify whether the case is pending with the association, vendor, DISCOM, meter provider, portal or bank and raise a tracked grievance with evidence.

Should the RWA create another application to fix an error?

No. Use the existing application’s correction or grievance route unless the official authority directs a fresh submission.

Can a relocated old solar plant receive fresh CFA?

The guideline states that relocating an already installed rooftop system does not create fresh CFA eligibility.

Plan the Society Project Around the Common Meter

A compliant RWA project begins with the common electricity connection and verified house count—not with the largest array a vendor can fit. Match the CFA ceiling, individual rooftop capacity, common load, roof, resolution, vendor, equipment, metering, inspection, bank account and maintenance into one transparent project file.

Read the complete PM Surya Ghar guide and understand feasibility and connection requirements through the feasibility-approval guide .

The residential 1kW , 2kW and 3kW cost guides are not direct quotations for a large RWA plant, but they help members understand major system components and household-scale pricing concepts.
