What the Official Guidelines Say About Vendor Choice
The operational guidelines say that the consumer chooses a vendor registered on the National Portal. The consumer and vendor mutually decide the system design, quality, components, additional features, local requirements, price and financial terms. The portal is intended to provide vendor comparison information, profiles, prices, performance data, feedback and ratings.
Consumer Chooses
The scheme does not require the consumer to buy from one DISCOM-tendered vendor.
Registered Vendor Required
A consumer claiming residential CFA must use a vendor registered on the National Portal.
Terms Are Mutually Decided
Design, equipment, price and payment are agreed between consumer and vendor.
Consumer Controls Portal Rights
The guidelines say consumers can perform portal activities without relying on the vendor.

How Difficult Is It to Change Vendor at Each Stage?
| Current project stage | Practical difficulty | Main action before switching |
|---|---|---|
| Only comparing quotations | Usually simple | Do not accept the first quote; choose another registered vendor |
| Vendor selected in portal, no agreement or payment | Generally easier | Check whether the consumer login allows re-selection; otherwise raise a correction request |
| Agreement signed, no advance or work | Contract review needed | Use termination, notice and cancellation terms |
| Advance paid, no materials | Payment settlement needed | Request itemised deduction and refund under the agreement |
| Materials delivered | Ownership and audit needed | Verify title, invoice, DCR, models, serials and storage risk |
| Partial installation | Complex | Measure completed work, test safety and obtain new-vendor acceptance |
| Full installation before portal completion | Complex | Audit physical plant and determine who signs PCR, invoice and warranty |
| Inspection correction pending | Highly sensitive | Correct inspection defects and update responsible-vendor records |
| Commissioned and CFA processed | Service transfer, not fresh installation | Preserve original vendor CMC, OEM warranties and portal history |
Interactive Vendor-Change Decision Planner
Select the current stage, payment and work status. The tool creates an educational checklist; it does not alter the National Portal or determine legal ownership.
- Compare other registered vendors and document the selected quotation.
- Check the consumer login for a vendor re-selection option.
- Raise a portal correction or grievance if the selected-vendor field is locked.
- Do not pay or sign until the final design and agreement are complete.
Reasons That May Justify Changing a Vendor
Repeated Delay
Survey, design, material, installation or upload milestones are repeatedly missed.
Registration Problem
The company is not registered for the relevant area or its portal status is unresolved.
Equipment Substitution
The vendor proposes a different module or inverter without written verification.
Non-DCR Risk
The vendor cannot establish domestic module and domestic cell compliance.
Unsafe Work
Structure, wiring, protection, earthing or access creates a serious safety concern.
Hidden Charges
Important civil work or equipment is added after advance without prior written scope.
No Documentation
The vendor refuses invoice, serial, warranty, drawing or portal-submission evidence.
Vendor Closure
The business closes, becomes unreachable or cannot complete the contracted work.
Changing Vendor Before Portal Selection
At the quotation stage, no vendor should control the consumer’s application or equipment decision. Compare registered profiles, specifications, prices, ratings, service capacity and written terms.
- Use the same system size and equipment scope for every quotation.
- Compare GST-inclusive price and site-specific extra work.
- Check DCR module and exact inverter models.
- Check installation, net meter, commissioning and five-year CMC scope.
- Check payment milestones and cancellation terms.
- Do not share OTP or give permanent control of the consumer login.

After Portal Vendor Selection but Before Agreement or Payment
This is usually the least complicated portal-linked stage for re-selection because the old vendor has not yet earned payment or created physical work. Nevertheless, the live consumer interface may lock the selected-vendor field after a particular action.
- Save the current application and selected-vendor screen.
- Notify the old vendor that no agreement or work is authorised.
- Check the consumer login for edit, cancel, re-select or enquiry controls.
- Choose only another currently registered vendor.
- Where the field is locked, raise a portal grievance requesting vendor re-mapping.
- Do not create a duplicate application merely to select another company.
Changing Vendor After Signing an Agreement
Once a written agreement exists, the scheme portal and the private contract become two separate issues. Changing the portal vendor does not automatically terminate the private agreement, and terminating the agreement does not automatically update the portal.
| Agreement item | What to check before termination |
|---|---|
| Cancellation clause | Notice period, reason, deduction and refund procedure |
| Payment milestones | Which stage was completed and which amount became due |
| Design ownership | Whether drawings, survey and engineering records can be transferred |
| Material procurement | Whether modules, inverter or structure were specifically ordered |
| Access and storage | Who holds delivered materials and risk before commissioning |
| Warranty | When warranty starts and whether uncommissioned equipment is registered |
| Dispute clause | Mutual settlement, notice, mediation, jurisdiction or other legal route |
| Portal responsibility | Who must release or correct vendor-linked records |
Changing Vendor After Paying an Advance
Advance recovery depends on the signed terms, actual work, specifically procured materials and applicable law. PM Surya Ghar does not convert every private advance into a government-guaranteed refundable deposit.
- Collect the agreement, quotation, receipt and bank-payment proof.
- Ask for an itemised statement of work and procurement completed.
- Ask for proof of any non-refundable custom order.
- Dispute unsupported deductions in writing.
- Agree on the exact refund, material handover or final settlement.
- Do not pay the new vendor for the same material before ownership is resolved.
- Keep portal re-selection separate from refund negotiations.
Amount paid − mutually accepted value of completed work − accepted non-returnable project-specific cost = proposed refund or balance.
This is a negotiation framework, not an official statutory formula.
Changing Vendor After Solar Materials Are Delivered
- Count every module and major component.
- Photograph labels, serials and packaging.
- Check invoice and delivery challan.
- Check DCR module evidence.
- Check inverter phase, MPPT and certification.
- Check whether the new vendor accepts the materials in writing.
- Record rejected, missing or damaged materials.
- Do not permit either vendor to remove disputed goods without written record.
Verify modules with the DCR solar-module guide and inverter details with the inverter-selection guide .
Changing Vendor After Partial Installation
A new vendor should not continue work without first accepting the condition and design of the previous work. Otherwise, both vendors may later deny responsibility.
| Audit area | New vendor must record |
|---|---|
| Roof and structure | Completed foundations, anchors, welds, corrosion protection, leakage and safe load path |
| Modules | Installed and uninstalled quantity, model, serial, damage and clamp condition |
| DC work | Strings, polarity, connector type, cable route and insulation condition |
| Inverter | Model, serial, mounting, input design and warranty-registration status |
| AC and protection | Boxes, breakers, surge protection, cables and earthing |
| Documents | Survey, layout, SLD, calculations, invoice and test records |
| Commercial value | Accepted completed work and corrective-work quotation |
| Responsibility | Which old work the new vendor accepts, corrects or excludes |
Changing Vendor After Full Installation but Before DISCOM Inspection
At this stage, the physical plant may be complete, but the contractual and portal record is not. The new vendor must decide whether it will inspect and accept the system, correct it, sign the Project Completion Report, assist with portal uploads, attend testing and commissioning and provide the five-year CMC.
- Complete an independent mechanical and electrical audit.
- Recalculate actual module DC capacity.
- Verify every module and inverter serial.
- Verify DCR and technical compliance.
- Check structure, clearance, cable and protection.
- Repeat test and earthing records.
- Determine who issues the final GST invoice.
- Determine who signs the PCR.
- Determine who accepts complete-system warranty and CMC.
- Correct the National Portal vendor mapping before inspection where required.
Use the complete installation-process guide .
Changing Vendor During DISCOM Correction or Inspection
When an inspection remark already exists, changing vendors must not erase the defect history. The new vendor should receive the inspection report, correct the physical system and update every associated record.
- Save the complete DISCOM remark or inspection report.
- Identify whether the defect was equipment, workmanship, document or portal data.
- Ask the old vendor to rectify its deficiency under the agreement and scheme duties.
- If switching, obtain the new vendor’s correction scope and responsibility in writing.
- Retest the corrected work.
- Update equipment, serial, invoice, PCR and photographs where needed.
- Use the official correction or re-inspection route.
Follow the DISCOM inspection guide and the rejected-application correction guide .
Can You Change Vendor After Commissioning?
After commissioning, the original registered vendor is normally tied to the project history, complete-system warranty and five-year comprehensive maintenance obligation. Hiring another company for service does not automatically transfer or release those obligations.
Original Vendor Still Responding
Use the original five-year CMC and OEM warranty-assistance route first.
Original Vendor Gives Written Release
Document remaining warranty, materials, service history and any accepted transfer.
Original Vendor Unreachable
Preserve notices, contact OEMs and raise a portal grievance before unauthorised repair.
Independent Service Provider
Check whether its work affects OEM warranties, portal records or electrical approvals.
Protect service rights with the maintenance and warranty guide .
How to Change the Vendor in the National Portal
The exact consumer-screen control can differ by application stage and portal update. Because the central guidelines do not define one universal screen-by-screen switch process, use the following safe sequence.
- Log in through the consumer’s own official profile.
- Save application ID, current vendor, status and every pending remark.
- Check whether vendor selection remains editable.
- If editable, select another currently registered vendor and save acknowledgement.
- If locked, use the correction, enquiry or grievance control linked to the application.
- State the old vendor, proposed new vendor, current stage and reason.
- Attach contract termination or no-work evidence where relevant.
- Attach material and technical audit when installation has begun.
- Ask the authority to identify any DISCOM or SIA approval required.
- Do not proceed with final upload or inspection until the vendor record is consistent.
Old-Vendor Exit Checklist
- Written termination, cancellation or dispute notice
- Application ID and portal-vendor status
- Final statement of payments and deductions
- Refund amount and due date
- List of delivered materials and ownership
- List and value of completed work
- Survey, DPR, layout, SLD and calculations
- Module and inverter serial records
- DCR, BIS, warranty and purchase documents
- Portal submissions and acknowledgements
- Inspection or correction records
- No-dues, no-objection or disputed-items statement
- Keys, monitoring credentials and communication devices
- Warranty registrations already completed
- Safety status of unfinished work
What the New Vendor Must Audit Before Accepting the Project
| Audit category | Minimum written result |
|---|---|
| Consumer and portal | Application, connection, approved capacity and current workflow |
| Roof and structure | Safety, anchoring, corrosion, clearance, leakage and access |
| Modules | Make, model, wattage, quantity, serials, DCR and condition |
| Inverter | Model, phase, AC rating, MPPT, voltage, current and certification |
| DC system | Strings, polarity, cable, connectors, isolation and labels |
| AC system | Cable, distribution connection, breaker, phase and meter route |
| Protection | Surge, anti-islanding, earthing, lightning and test results |
| Documentation | Invoice, PCR, drawings, photographs, warranties and portal records |
| Corrective work | Defects, cost, timeline and responsible party |
| Acceptance scope | What the new vendor warrants and what it excludes |
Documents and Records to Transfer to the New Vendor
- Electricity bill and consumer details
- National Portal application ID and status history
- Feasibility, deemed-acceptance or load record
- Old quotation and agreement
- Payment receipts and settlement
- Roof survey and structural records
- Final or draft layout and single-line diagram
- Module DCR, model and serial records
- Inverter model, serial and compliance records
- Material delivery challans and invoice
- Test and earthing reports
- Portal uploads and geo-tagged photographs
- Inspection, correction and meter records
- Loan documents and bank details where relevant
- OEM warranties and monitoring credentials
Organise these with the complete PM Surya Ghar document checklist .
Advance, Refund and Payment Settlement
The model agreement allows milestone-based payments and says project cost and payment terms are mutually decided. It also says disputes are settled mutually or according to law, without making MNRE or the DISCOM a party.
| Money issue | Evidence required | Possible settlement item |
|---|---|---|
| Booking advance | Receipt and cancellation clause | Refund less accepted documented work |
| Survey or engineering fee | Delivered report, design and agreed fee | Accepted payment or transfer of usable records |
| Custom structure | Purchase and fabrication evidence | Handover, resale, cancellation deduction or dispute |
| Modules or inverter | Invoice, serials, delivery and payment | Consumer ownership, vendor return or settlement |
| Partial installation | Measured completed work and defect audit | Accepted value less corrective work |
| Refund delay | Written settlement and due date | Formal demand and applicable dispute route |
Who Owns Modules and Equipment Already Delivered?
Ownership cannot be decided only from the fact that equipment is lying at the consumer’s property. Check the signed agreement, tax invoice, delivery challan, payment, title-retention term and applicable law.
- Whose name appears on the tax invoice?
- Was the equipment fully paid?
- Does the agreement retain title with the vendor until payment?
- Was delivery conditional or final?
- Are serial numbers identified in the invoice or challan?
- Who carries insurance risk before commissioning?
- Is the material project-specific and returnable?
- Did the consumer sign a goods-receipt or acceptance note?
Changing Vendor When a Solar Loan Is Approved
A lender may have approved a particular quotation, vendor, invoice or project cost. Changing vendors can therefore require lender approval and a revised disbursal file.
- Notify the lender before changing the quotation or payee.
- Check whether any amount was disbursed to the old vendor.
- Obtain cancellation, refund or utilisation evidence.
- Submit the new registered vendor’s quotation and bank details.
- Reconfirm project cost, capacity and eligible CFA.
- Correct the linked loan account and portal records where necessary.
- Do not use loan funds twice for the same equipment or milestone.

Warranty and Five-Year CMC After a Vendor Change
The scheme requires a registered vendor to provide five years of repair and maintenance from commissioning, while the model agreement describes complete-system warranty, commissioning support, net-meter work and OEM warranty assistance. These duties need clear allocation after a switch.
Before Commissioning
The new vendor can agree to take full installation, commissioning and CMC responsibility.
Inherited Equipment
The new vendor should list which old components it accepts under its system warranty.
OEM Warranty
Manufacturer warranty may continue if invoice, serial, installation and authorised service conditions are met.
After Commissioning
A third-party service contract does not automatically transfer the old vendor’s scheme CMC.
- Name the entity responsible for complete-system warranty.
- Name the entity responsible for five-year CMC.
- List inherited components excluded by the new vendor.
- Preserve original OEM invoices and serials.
- Confirm whether unauthorised repair affects warranty.
- Update replacement and service history.
Official Grievance Route for Vendor Change or Non-Performance
Consumers can raise grievances through the National Portal, portal app or National Call Centre. The operational guidelines state that a unique tracking ID is created and grievances are to be resolved within 30 days. A March 2026 government update stated that call-centre number 15555 was operational in 12 languages.
- Use the consumer’s own portal profile.
- Select the correct application and vendor-related category.
- State the old vendor and current project stage.
- Explain whether agreement, payment, delivery or installation exists.
- State the proposed new registered vendor, when selected.
- Request the exact portal correction or re-mapping needed.
- Attach termination, settlement, audit and supporting records.
- Save the unique grievance tracking ID.
- Follow up through the same ticket.

Vendor-Change Scams and Red Flags
New Application Without Explanation
A new vendor creates another claim instead of correcting the existing application.
Fake No-Objection Letter
A document is created without the old vendor’s verifiable authority or signature.
Advance Recovery Fee
An agent asks for money to guarantee refund from the old vendor.
Second Invoice for Same Material
The consumer pays again before ownership of delivered goods is resolved.
Portal OTP Takeover
The new vendor requests unrestricted login control rather than consumer-supervised assistance.
False Inspection Transfer
The consumer is told the DISCOM will ignore mismatched vendor, invoice or equipment records.
- Verify both vendors on the official portal.
- Keep OTP, password and bank credentials private.
- Check every invoice and serial before paying again.
- Use written settlement and portal acknowledgements.
- Report suspected forgery, bribery or fraud to appropriate authorities.
Frequently Asked Questions
Can I change my vendor under PM Surya Ghar?
Consumers are free to choose a registered vendor, but the switching process depends on the portal stage, private agreement, payment, delivered materials and completed work.
Is there one official change-vendor button?
The central guidelines do not publish one universal button or process for every stage. Check the current consumer login and use correction or grievance when the field is locked.
Can I change before signing an agreement?
This is generally the simplest stage. Choose another registered vendor and correct the portal selection if one was already made.
Can I change after paying an advance?
Yes, but refund and deductions depend on the agreement, actual work, procurement and applicable law.
Will MNRE recover my advance?
The model agreement says vendor-consumer payment disputes are private and must be settled mutually or according to law; MNRE and DISCOM are not parties to them.
Can the new vendor use materials supplied by the old vendor?
Only after ownership, condition, DCR, exact models, serials, technical compatibility and new-vendor acceptance are documented.
Can I keep the old modules and change only the installer?
Potentially, when the modules are compliant, owned by the consumer and accepted by the new registered vendor after audit.
What if the old vendor installed non-DCR modules?
A CFA-claiming installation must be physically corrected with compliant modules; changing the vendor name alone does not fix DCR ineligibility.
Can I change after partial installation?
Yes, but obtain a detailed audit, completed-work measurement, safety report, payment settlement and written responsibility from the new vendor.
Who signs the Project Completion Report after a change?
Confirm the current portal requirement and ensure the vendor taking responsibility for completion signs accurate records. Do not use a signature from a vendor that did not verify the plant.
Can I change during DISCOM inspection?
The application may need vendor re-mapping and correction. The physical inspection defects and all records must still be resolved.
Can I change after commissioning?
You can hire another service provider, but this does not automatically transfer the original vendor’s five-year CMC or OEM warranty obligations.
Does changing vendor affect subsidy?
A properly documented switch to another registered vendor should focus on preserving eligibility. Mismatched equipment, invoice, portal or inspection records can delay or block CFA.
Does the new vendor need to be registered?
Yes, a consumer claiming residential CFA must choose a vendor registered on the National Portal.
Can the consumer update the portal without the vendor?
The guidelines state that consumers have user rights to undertake portal activities without relying on the vendor.
What if the portal does not allow vendor editing?
Raise a correction or tracked grievance under the existing application and request the exact re-mapping process.
How long should a vendor-related grievance take?
The operational guidelines state a 30-day grievance-resolution period. Preserve the tracking ID.
What if the old vendor refuses documents?
Send a written demand, attach the agreement and payments to a portal grievance and use the applicable dispute or consumer-protection route.
Should the new vendor guarantee the old work?
Only the work and materials it inspected and expressly accepted should be treated as covered. Record exclusions and corrective work.
Can a loan be transferred to the new vendor?
The lender may need a revised quotation, payee approval, refund evidence and new disbursal instructions. Obtain lender approval before switching.
Change the Vendor Without Breaking the Evidence Chain
A successful vendor change preserves one consistent project history: consumer, application, approved capacity, payments, materials, serials, DCR, inverter, design, inspection, invoice, warranty and CMC. The earlier the change occurs, the easier it is. Once physical work begins, written audit and responsibility become essential.
