Checks Before the Vendor Site Survey

Check consumer eligibility with the PM Surya Ghar eligibility guide and prepare the records listed in the documents checklist .

What a Proper Solar Site Survey Must Cover

Use the rooftop-area and shade guide to verify the proposed layout.

Freeze the Solar Design Before Material Is Ordered

• Exact module DC capacity
• Module manufacturer, model, wattage, quantity and DCR evidence
• Inverter manufacturer, model, phase, AC rating and MPPT layout
• Module-row arrangement and roof orientation
• Mounting-structure material, height, finish and anchoring
• DC and AC cable sizes and approximate routes
• Protection boxes, breakers, isolators and surge protection
• Earthing electrodes and connection plan
• Metering and DISCOM coordination responsibility
• Expected annual generation and written assumptions
• Confirmed civil, waterproofing and extra work
• Future expansion or battery plan, where real

Select capacity with the home system-size guide , verify module eligibility in the DCR solar-module guide , and match the inverter through the inverter-selection guide .

Vendor Agreement and Payment Terms Before Installation

Compare vendors with the registered-vendor selection guide .

Verify Solar Materials at Delivery

• Photograph cartons, labels and serial numbers before installation.
• Count all modules and major equipment.
• Check transport damage and water exposure.
• Match the delivery challan to the signed quotation.
• Reject undocumented last-minute substitutions.
• Keep the delivery document and invoice reference.

Mounting-Structure Installation

The structure transfers module and wind loads to the roof. It must support safe tilt, drainage, maintenance access and long-term corrosion resistance.

• Confirm structure layout against the approved drawing.
• Mark anchor points before drilling or fixing.
• Protect waterproofing and seal approved penetrations.
• Check alignment, level, tilt and row spacing.
• Use specified fasteners, torque and corrosion protection.
• Preserve drains, tank access and maintenance walkways.
• Check wind bracing and elevated-structure members.
• Remove sharp edges and unsafe protrusions.
• Photograph concealed anchors before modules cover them.
• Inspect the roof for new cracks or leakage risk.

Solar-Module Mounting and String Assembly

1. Move modules using safe lifting and handling methods.
2. Place each module in the approved roof position.
3. Use manufacturer-compatible clamps and approved clamp zones.
4. Apply specified fastener torque without damaging frames.
5. Maintain module gaps, row spacing and access.
6. Connect modules in the approved string sequence.
7. Secure cables away from sharp edges, standing water and the roof surface.
8. Use compatible connectors and avoid unsafe mixed connector pairs.
9. Label strings and record the module serial map.
10. Check module glass, frame and junction boxes after installation.

Solar-Inverter Installation

• Match the physical serial and model with documents.
• Install specified DC and AC isolation.
• Use approved cable glands and sealed entries.
• Connect protective earth correctly.
• Provide monitoring communication and consumer access.
• Keep shutdown and warning labels visible.

DC and AC Cable Installation

Protection, Isolation, Earthing and Lightning Risk

• DC isolation and protective device arrangement
• AC circuit breaker and isolation
• DC and AC surge-protection devices where required
• Inverter earth-fault and anti-islanding functions
• Module-frame and structure bonding
• Inverter-enclosure protective earthing
• Earth electrodes and measured resistance
• Lightning-protection coordination where the site requires it
• Safe emergency shutdown labels
• Protection settings that match the approved design

Pre-Commissioning Mechanical and Electrical Tests

Portal Completion, Invoice and Project Records

After installation, the vendor or responsible party uploads project-completion details through the prescribed National Portal workflow. The data should exactly match the physical plant.

• Actual installed module DC capacity
• Module manufacturer, model, wattage, quantity and serial records
• Inverter manufacturer, model, rating, phase and serial
• GST tax invoice and payment records
• Project Completion Report
• Required geo-tagged photographs
• Metering and agreement documents
• Consumer and bank details for CFA
• Loan-account linkage where applicable
• Correction of every physical and portal mismatch

What Happens During DISCOM Inspection?

The DISCOM verifies the installation against the application, technical checklist, metering rules and physical equipment. It can approve the project, return it for correction or reject it with reasons.

• Consumer number and installation address
• Installed module capacity
• DCR modules and equipment details
• Inverter rating, phase and protection
• Structure, cable and electrical safety
• Earthing and isolation
• Meter and point-of-connection arrangement
• Portal documents and photographs
• Net-metering or applicable agreement
• Correction closure before final approval

Bidirectional Meter and Metering Agreement

The approved meter records electricity imported from and exported to the grid under the State’s applicable arrangement. The Government has also reported that the net metering agreement has been integrated into the National Portal application process.

1. Confirm the approved metering mechanism.
2. Confirm who supplies and pays for the meter and testing.
3. Check meter make, number, phase and ratio where applicable.
4. Record the old meter’s final reading.
5. Record the new meter’s initial import and export readings.
6. Confirm wiring direction and meter display parameters.
7. Keep the meter installation report and agreement.
8. Review the first solar bill for correct import and export treatment.

Commissioning and Grid Synchronisation

Commissioning is the formal confirmation that the approved system is installed, tested, metered and operating safely. It should not be confused with the first day that an installer temporarily switches on the inverter.

• Required approvals and meter are complete.
• Final protection settings are confirmed.
• Inverter synchronises without persistent alarms.
• Import and export readings move in the correct direction.
• Monitoring shows expected strings or MPPTs.
• Anti-islanding and shutdown instructions are demonstrated.
• Commissioning date is recorded.
• Initial daily generation is recorded for comparison.
• Completion and commissioning documents are signed.

Consumer Handover Package After Installation

Use the subsidy-payment status guide after commissioning, and review loan adjustment through the PM Surya Ghar solar-loan guide .

How Long Can the Installation Process Take?

There is no single guaranteed nationwide completion time. The physical rooftop work can be relatively short for a simple home, while approval, material availability, weather, meter supply, corrections and finance can extend the complete project.

Illustrative Safer Payment Milestones

The percentages and stages should be negotiated for the project. This table is a risk-control example, not an official PM Surya Ghar payment schedule.

Frequently Asked Questions

Installation Is Complete Only After Safe Commissioning and Handover

A rooftop array visible from the street is not proof of a completed PM Surya Ghar project. The consumer should be able to match every module and inverter to the agreement, see passed test records, confirm DISCOM and meter completion, access monitoring and hold the warranties, serials and maintenance contacts.
