3kW Solar Panel Cost Under PM Surya Ghar 2026: ₹78,000 Subsidy and Price Guide

3kW PM Surya Ghar Cost Summary

How the ₹1,45,000 Benchmark-Derived Reference Is Calculated

The scheme’s original policy explanation described CFA as 60% of benchmark system cost for the first 2kW and 40% of the additional benchmark system cost between 2kW and 3kW. Applying the notified ₹60,000 and ₹18,000 standard assistance produces:

This calculation explains the official subsidy design. It is not a current retail ceiling, minimum, approved vendor tariff or promise that every roof can be completed at the reference figure.

How the 5% Renewable-Energy GST Reform Affects 3kW Cost

The Government announced that GST across renewable-energy devices would be rationalised from 12% to 5%, effective September 22, 2025. It estimated that a typical 3kW rooftop-solar system could become approximately ₹9,000–₹10,500 cheaper and that module and component costs could decline by roughly 3–4%.

Illustrative 3kW Quotation and Effective-Cost Examples

These figures demonstrate how ₹78,000 standard CFA interacts with different vendor quotations. They are mathematical examples, not claims about current market prices.

What Is the Extra Cost of Moving From 2kW to 3kW?

The third kilowatt receives a lower subsidy rate than the first two kilowatts. This makes the marginal comparison especially important.

The ₹27,000 figure is a reference calculation, not a guaranteed upgrade price. Actual marginal cost depends on whether the existing inverter, structure, protection and cable design change with the third kilowatt.

• AC and DC cables, connectors, conduit and labels
• AC/DC distribution boxes, isolation and surge protection
• Earthing and any required lightning protection
• Transport, lifting, labour and rooftop access
• Testing and commissioning
• National Portal documentation and geo-tagged photographs
• Project Completion Report support
• DISCOM inspection and meter-coordination scope
• GST-inclusive final price
• Manufacturer and system warranty
• Five-year comprehensive maintenance support

Roof and Layout Planning for a 3kW System

A 3kW array needs a meaningful area of safe, unshaded roof, but publishing one universal square-foot requirement can be misleading. Module size, tilt, row spacing, parapet shade, water tanks, access paths, structure type and wind design determine the final layout.

• Measure usable unshaded roof rather than total terrace area.
• Check seasonal shade from buildings, trees, tanks and parapets.
• Keep maintenance, cleaning and emergency access.
• Protect roof drainage and waterproofing.
• Assess structural load and anchoring.
• Plan cable routes and inverter location before signing.
• Confirm wind exposure for elevated structures.
• Keep module rows accessible for inspection.
• Obtain co-owner, landlord or RWA permission where needed.
• Document future-expansion plans before selecting the inverter and structure.

How Much Electricity Can a 3kW System Generate?

Government consumer communication states that a 3kW rooftop system can generate more than 300 units per month on average. Treat this as a broad programme example, not a guarantee for every roof. Actual output varies with:

• Location and annual solar resource
• Season, clouds and rainfall
• Module direction and tilt
• Shade at different times of day
• Module temperature and ventilation
• Dust, pollution and cleaning
• Inverter efficiency and clipping
• DC/AC cable losses
• Grid outages and inverter shutdown
• Equipment downtime and degradation

Official guidance places households consuming approximately 150–300 units per month in the 2–3kW capacity band. A home consistently using more than 300 units may consider a system above 3kW, but standard household CFA remains capped at ₹78,000.

Which Household Should Consider 3kW?

3kW May Not Be the Best Choice When

• Consumption is much lower and unlikely to grow.
• The usable roof is heavily shaded or structurally unsuitable.
• Consumption is far above 300 units and a larger system has better economics.
• The household chooses 3kW only to obtain the maximum subsidy.
• The quote requires excessive civil or elevated-structure work.
• The DISCOM billing arrangement makes surplus export less valuable than direct use.

2kW vs 3kW vs Above 3kW

Smaller-system economics are covered in the 1kW cost guide and 2kW cost guide .

How to Receive the ₹78,000 Standard Subsidy

1. Register the eligible residential electricity consumer on the official PM Surya Ghar National Portal.
2. Submit the correct State, DISCOM, consumer number and proposed system details.
3. Select a vendor registered for the relevant service area.
4. Sign a written agreement and install an eligible grid-connected 3kW system using DCR-compliant modules.
5. Upload the invoice, system details, completion records and required geo-tagged photographs.
6. Complete DISCOM inspection, approved metering and commissioning.
7. Confirm that the e-token activates for the actual eligible capacity and amount.
8. Redeem the token, complete bank or linked-loan validation and track CFA credit.

Follow the online application guide , check the load and approval process , complete the net-meter process , and track the final amount through the subsidy-payment status guide .

3kW Solar Loan and Illustrative EMI

The March 2026 Government update described collateral-free credit from nationalised banks at repo rate plus 50 basis points—5.75% per annum at that time—with tenure up to 10 years. The live lender offer and sanction letter determine the borrower’s actual rate, loan amount, fees, margin and tenure.

These are illustrative reducing-balance calculations without fees, insurance or later benchmark changes. Read the PM Surya Ghar solar-loan guide before accepting finance.

How to Estimate 3kW Payback

A useful payback model must use the final project price, actual CFA, location-specific generation and the current DISCOM settlement method.

• Use the GST-inclusive final invoice.
• Subtract only the CFA actually credited.
• Use conservative annual generation.
• Separate direct self-consumption from export.
• Apply the current import tariff and export value.
• Do not count fixed charges as avoided unless the tariff removes them.
• Add loan interest and fees.
• Allow for cleaning, maintenance and possible inverter repair.
• Check low-generation and high-generation scenarios.
• Do not assume electricity tariffs or export rules remain unchanged forever.

Warranty and Maintenance for a 3kW System

The official model vendor-consumer agreement includes five years of comprehensive operation and maintenance from commissioning. Confirm the service scope, component warranties and local response arrangements in writing.

• Module product and performance warranties
• Inverter product warranty and authorised service route
• Five-year vendor maintenance start date
• Monitoring and generation review
• Shutdown and alarm response time
• Structure, fastener and corrosion inspection
• Cable, protection and earthing checks
• Cleaning instructions and responsibility
• Travel, labour and replacement exclusions
• Service after the five-year commitment

Common Mistakes When Buying a 3kW System

Frequently Asked Questions

Choose 3kW for Consumption and Roof—Not Only for Maximum CFA

₹78,000 is the maximum standard household assistance, but maximum subsidy does not automatically make 3kW the correct system for every property. Compare the full quotation, usable roof, generation estimate, current GST treatment, direct self-consumption, export settlement and future electricity demand.

Before paying, review the complete PM Surya Ghar guide , follow the online application process , verify the connection and load process , and track the claim through the subsidy-payment guide .
