RWA Subsidy Calculation Examples

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.

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.

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

RWA Common Subsidy vs Individual Household Subsidy

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

Audit the Common Electricity Load Before Choosing Capacity

• 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.

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

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.

Documents Required for an RWA/GHS Solar Application

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

Organise the technical file with the PM Surya Ghar documents guide .

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 .

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 .

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 .

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.

• 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 .

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.

Calculate Common-Area Solar Savings Correctly

• 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 .

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.
