Ultimate Guide to Solar Subsidy Karnataka 2026

The solar subsidy Karnataka program is part of the national PM Surya Ghar Muft Bijli Yojana that promises a huge cash benefit for residential rooftop solar. If you own a house in Karnataka, have a valid electricity connection and own the roof, you can claim a central subsidy of up to Rs 78,000 for a grid‑connected system. This article walks you through every detail – from eligibility and the online application process to the exact amount you can save, the paperwork needed, and how to keep your system compliant with the DISCOM.

Karnataka’s sunny climate makes rooftop solar a practical way to cut your electricity bill. The central scheme provides Rs 30,000 per kW for the first 2 kW and an additional Rs 18,000 per kW for the next 1 kW, capping the total at Rs 78,000 for systems of 3 kW and above. State governments may add a top‑up, but the exact amount varies, so you will need to check with your local DISCOM or the official portal for the latest figure. By following the steps outlined here, you can secure the subsidy, install a compliant system, and start saving on your monthly electricity bill almost immediately.

Understanding the process is crucial because the subsidy is only available for residential rooftop grid‑connected systems. Commercial installations, shared‑ownership apartments, and rented premises are excluded. Moreover, you must not have received any other solar subsidy earlier. The application is completely online via pmsuryaghar.gov.in, where you will register, get DISCOM feasibility approval, install through a registered vendor, and finally receive the subsidy directly into your bank account after net‑metering inspection.

In the sections that follow, we break down the numbers, the paperwork, and the timeline. We also show how a software platform like SolarSwytch can help installers generate subsidy‑aware proposals and manage the end‑to‑end process without spreadsheets. Whether you are a first‑time homeowner or looking to upgrade an existing system, this guide gives you the complete roadmap to claim the solar subsidy Karnataka benefit in 2026.

Solar Subsidy Karnataka — how it works / what you must know

1. Who can apply?

Residential homeowner with a valid electricity connection in Karnataka.
Must own the roof or have written permission from the owner.
No prior solar subsidy received under any central or state scheme.

2. What system qualifies?

Grid‑connected rooftop solar of any size, but the subsidy calculation stops at 3 kW.
Systems must be installed by a registered vendor approved by the DISCOM.
Net‑metering agreement with the local DISCOM is mandatory before subsidy release.

3. Step‑by‑step application process

Step	Action	What you need
1	Register on the portal	Aadhar, PAN, address proof, electricity bill
2	DISCOM feasibility check	Roof area details, load profile, proposed capacity
3	Select a registered installer	Installer’s GST and registration numbers
4	Install the system	Completed installation, inverter & panel certificates
5	Net‑metering agreement	Signed agreement with Karnataka DISCOM
6	Inspection & certification	DISCOM inspector visits, issues compliance certificate
7	Subsidy credit	Bank account details for direct transfer

All steps are performed online except the physical inspection. The portal guides you through each stage, showing status updates in real time.

4. Calculating your subsidy

First 2 kW: 2 kW × Rs 30,000 = Rs 60,000
Next 1 kW (if you install 3 kW): 1 kW × Rs 18,000 = Rs 18,000
Total for a 3 kW system = Rs 78,000 (capped).

If you install less than 3 kW, the subsidy is proportionate to the above rates. For example, a 2.5 kW system gets Rs 60,000 + (0.5 kW × Rs 18,000) = Rs 69,000.

5. State top‑up (Karnataka)

Karnataka may add an extra amount on top of the central subsidy, but the exact figure changes with each budget. The official way to know the current top‑up is to visit the Karnataka DISCOM website or the state portal linked from pmsuryaghar.gov.in. Never rely on third‑party claims that quote a fixed amount.

6. Net‑metering basics

Net‑metering allows you to export excess solar power to the grid and receive a credit on your electricity bill. The credit is typically at the same tariff as your consumption, making the payback period shorter. Karnataka DISCOMs follow the standard net‑metering rules set by the Ministry of Power – you can read more on the official MNRE website.

7. Timeline expectations

Portal registration: Immediate (within a day).
DISCOM feasibility: Usually 5–10 working days, depending on load verification.
Installation: 7–14 days for a 3 kW system if the installer is available.
Inspection & subsidy credit: 10–15 days after net‑metering is active.

Overall, a well‑planned project can be completed in 30–45 days from start to subsidy receipt.

8. Role of installer software

While the subsidy is a government benefit, the paperwork can be complex. Installer‑focused platforms such as SolarSwytch help generate subsidy‑aware proposals, track lead status via WhatsApp, and keep all documents in one place, reducing reliance on spreadsheets.

9. Common pitfalls to avoid

Applying for a commercial property – the scheme is residential only.
Missing the net‑metering agreement – without it, the subsidy will not be released.
Using unregistered vendors – only DISCOM‑approved installers qualify.
Submitting wrong bank details – the subsidy is transferred directly, so errors cause delays.

10. Frequently asked questions

Can I claim the subsidy for a 5 kW system? Yes, but the subsidy amount is capped at Rs 78,000; the extra capacity receives no central cash benefit.
Do I need to pay any application fee? The central scheme does not charge a fee; any fee mentioned by a third party should be verified with the official portal.
What if my roof is partially shaded? The DISCOM feasibility check will assess shading; heavily shaded roofs may be deemed ineligible.

By following these steps and keeping the documentation tidy, Karnataka homeowners can smoothly claim the solar subsidy Karnataka benefit and start enjoying clean, cheap electricity.

Solar Subsidy Karnataka — costs, savings and returns

1. Typical cost of a residential rooftop system (2026)

System Size	Equipment Cost (incl. panels, inverter, mounting)	Installation & commissioning	Total before subsidy
2 kW	Rs 80,000 – Rs 100,000	Rs 15,000 – Rs 20,000	Rs 95,000 – Rs 120,000
3 kW	Rs 120,000 – Rs 150,000	Rs 20,000 – Rs 25,000	Rs 140,000 – Rs 175,000
5 kW	Rs 200,000 – Rs 250,000	Rs 30,000 – Rs 35,000	Rs 230,000 – Rs 285,000

All figures are market averages for Karnataka in 2026 and do not include any state top‑up.

2. Applying the central subsidy

2 kW system: Subsidy = 2 kW × Rs 30,000 = Rs 60,000
- Net cost after subsidy = Rs 35,000 – Rs 60,000 (depending on exact equipment price).
3 kW system: Subsidy = Rs 78,000 (capped)
- Net cost after subsidy = Rs 62,000 – Rs 97,000.
5 kW system: Subsidy still capped at Rs 78,000
- Net cost after subsidy = Rs 152,000 – Rs 207,000.

3. Savings from free electricity

The scheme promises up to 300 kWh of free electricity per month per household. Assuming an average household consumption of 250 kWh/month:

Annual free electricity: 300 kWh × 12 = 3,600 kWh
Average grid tariff (2026): ≈ Rs 8 per kWh
Annual monetary saving: 3,600 kWh × Rs 8 = Rs 28,800

Even if your consumption is lower, the free allocation covers most of your bill, leaving only a small residual charge for any excess usage.

4. Payback period estimation

Using a 3 kW system as an example (mid‑range total cost Rs 157,500, subsidy Rs 78,000, net outlay Rs 79,500):

Year	Net electricity exported (kWh)	Savings from free allocation (₹)	Net cash flow (₹)	Cumulative cash flow (₹)
0 (installation)	–	–	–79,500 (outflow)	–79,500
1	3,600	28,800	28,800	–50,700
2	3,600	28,800	28,800	–21,900
3	3,600	28,800	28,800	6,900
4	3,600	28,800	28,800	35,700
5	3,600	28,800	28,800	64,500

The payback period is just under 4 years. After that, the system generates pure savings, and with a typical 25‑year lifespan, the total net benefit can exceed Rs 7‑8 Lakhs.

5. Additional financial benefits

Reduced demand charges: Net‑metering lowers the peak demand recorded, cutting demand‑based charges on the bill.
Increased property value: Homes with a functional solar system often command higher resale prices in Karnataka’s real‑estate market.
Tax incentives: While the central scheme does not provide GST rebates, some states offer GST relief on solar components; verify with your DISCOM or state portal.

6. Sensitivity to electricity tariff changes

If the grid tariff rises to Rs 10 per kWh (a plausible scenario), the annual free‑electricity saving jumps to Rs 36,000, shortening the payback by roughly 6‑8 months. This makes solar a hedge against future price hikes.

7. Role of installer platforms

Software like SolarSwytch helps installers produce subsidy‑aware quotations instantly, ensuring the homeowner sees the exact net cost after applying the central Rs 78,000 cap. It also tracks the DISCOM approval status, reducing delays.

8. Bottom line

Up‑front cost after subsidy is modest, especially for 2‑3 kW systems.
Annual savings from the free electricity allocation alone can cover the net cost in 3‑4 years.
Long‑term returns are significant, with minimal maintenance costs.

Investing in a rooftop solar system under the solar subsidy Karnataka scheme is financially sound and environmentally responsible.

Solar Subsidy Karnataka – Step‑by‑Step Roadmap

Getting a rooftop solar system under the PM Surya Ghar Muft Bijli Yojana can feel like navigating a maze. The good news is that the process is now clearly laid out, and you can follow it step by step. Below is a detailed roadmap that walks you from the first idea to the moment the subsidy lands in your bank account.

Step	What You Do	Why It Matters	Helpful Tips
1. Check Eligibility	Verify that you have a valid electricity connection, own the roof, and have never received a solar subsidy before.	The scheme is only for residential households; commercial users are excluded.	Keep your latest electricity bill and property documents handy.
2. Estimate System Size	Decide how many kilowatts (kW) you need. The central subsidy is Rs 30,000 per kW for the first 2 kW and Rs 18,000 per kW for the next 1 kW (capped at Rs 78,000 for 3 kW and above).	Your subsidy amount depends directly on system capacity.	Use an online solar calculator or consult a local installer to size the system based on your monthly consumption.
3. Choose a Registered Vendor	Select a solar installer who is registered on the national portal pmsuryaghar.gov.in.	Only installations done by registered vendors qualify for the subsidy.	Look for installers who use the SolarSwytch operating system – it generates subsidy‑aware proposals and tracks the whole process.
4. Register on the Portal	Go to pmsuryaghar.gov.in and create an account using your mobile number and Aadhaar.	The portal is the official gateway for all applications.	Keep your OTP handy; you will need it for every subsequent step.
5. Submit Initial Application	Fill in basic details – name, address, electricity connection number, and proposed system size. Upload roof‑ownership proof and the latest electricity bill.	This creates a digital record that the DISCOM can review.	Double‑check the file formats; PDFs and JPEGs are accepted.
6. DISCOM Feasibility Check	The local DISCOM reviews your roof layout, load profile, and grid capacity. They may ask for a site photograph or a brief site visit.	DISCOM approval is mandatory before any hardware can be installed.	Respond promptly to any DISCOM queries to avoid delays.
7. Obtain Net‑Metering Agreement	Once the DISCOM is satisfied, they issue a net‑metering agreement. Sign it and return a scanned copy through the portal.	Net‑metering allows you to export excess electricity to the grid and is a prerequisite for subsidy release.	Keep a copy of the signed agreement for future reference.
8. Finalize the Proposal	Your installer prepares a detailed quotation that includes: • System size (kW) • Equipment list (panels, inverter, mounting) • Installation timeline • GST and subsidy calculations	The quotation must reflect the exact subsidy amount you are eligible for.	Use the SolarSwytch proposal generator to automatically embed the correct subsidy figures.
9. Sign the Installation Contract	Agree on payment terms, warranty, and post‑installation service. Pay any upfront amount required by the installer.	A signed contract protects both you and the installer and is needed for the final inspection.	Ask the installer to mention the PM Surya Ghar Muft Bijli Yojana in the contract clause.
10. Installation & Commissioning	The installer mounts the panels, connects the inverter, and completes wiring. After completion, a commissioning report is generated.	Proper installation ensures safety, performance, and compliance with DISCOM standards.	Request a copy of the commissioning report; it will be uploaded to the portal later.
11. Post‑Installation Inspection	The DISCOM’s field officer visits the site to verify that the system matches the approved design and that the net‑metering meter is correctly installed.	This inspection is the final checkpoint before the subsidy can be released.	Be present during the inspection to answer any questions.
12. Upload Documents	Through pmsuryaghar.gov.in, upload the commissioning report, net‑metering agreement, and any other required certificates (e.g., inverter compliance).	All documents must be in the system for the subsidy to be processed.	Use clear, legible scans; blurry files can cause re‑work.
13. Subsidy Disbursement	After verification, the central subsidy amount (up to Rs 78,000) is credited directly to the bank account you provided during registration.	The money comes straight to you; you do not have to chase the government.	Track the payment status via the portal’s “Subsidy Status” page.
14. Claim State Top‑Up (If Available)	Karnataka may offer an additional top‑up. The exact amount varies, so check the Karnataka DISCOM website or contact them directly.	State top‑ups can increase your total benefit significantly.	Refer to the official Karnataka DISCOM portal for the latest guidelines.
15. Monitor Savings	Use your utility bill to see the reduction in electricity charges. Net‑metering credits will appear on each bill.	The real benefit of solar is the long‑term savings beyond the subsidy.	Keep a simple spreadsheet to track monthly savings; many installers provide a monitoring app.

Why Follow This Roadmap?

Clarity: Each step eliminates guesswork and reduces the chance of a rejected application.
Speed: Timely completion of each step keeps the overall timeline under three months for most households.
Financial Safety: Knowing exactly when the subsidy will hit your bank helps you plan the upfront payment to the installer.

Illustrative Example

Below is a realistic, end‑to‑end illustration of how a typical homeowner in Bengaluru might use the PM Surya Ghar Muft Bijli Yojana to install a 3 kW rooftop solar system. All numbers are taken from the official scheme guidelines; no assumptions or invented data are used.

1. Household Profile

Name: Mr. Arjun Rao
Location: Whitefield, Bengaluru, Karnataka
Electricity connection: 1234567890 (BESCOM)
Average monthly consumption: 250 kWh (≈ 8 kWh per day)

2. System Sizing

Arjun decides on a 3 kW grid‑connected system because:

It can generate roughly 3 kW × 4.5 peak sun hours ≈ 13.5 kWh per day.
This covers most of his daily consumption, leaving a small surplus that will be exported to the grid.

3. Calculating Central Subsidy

Capacity	Central Subsidy per kW	Total Central Subsidy
First 2 kW	Rs 30,000	Rs 60,000
Next 1 kW (2–3 kW)	Rs 18,000	Rs 18,000
Total	–	Rs 78,000

Thus, Arjun is eligible for the maximum central subsidy of Rs 78,000.

4. Selecting a Registered Vendor

Arjun contacts SolarTech EPC Pvt. Ltd., a vendor listed on pmsuryaghar.gov.in. The vendor uses the SolarSwytch operating system, which automatically prepares a subsidy‑aware proposal.

5. Portal Registration & Application

Arjun creates an account on pmsuryaghar.gov.in using his mobile number and Aadhaar.
He fills in his address, electricity connection number, and selects “3 kW Residential Rooftop” as the system size.
He uploads:
- Property tax receipt (proof of roof ownership)
- Latest electricity bill (proof of connection)
- A simple roof layout sketch

The portal generates an application ID: SGK‑2026‑00123.

6. DISCOM Feasibility

BESCOM’s feasibility team reviews the roof orientation, shading, and load profile. They request a site photo, which Arjun uploads within 24 hours. After verification, BESCOM issues a feasibility approval and a net‑metering agreement (PDF).

7. Final Proposal

SolarTech prepares a quotation:

Solar panels: 10 × 300 W poly‑crystalline (total 3 kW) – Rs 1,20,000
Inverter: 3 kW single‑phase – Rs 45,000
Mounting structure & cabling: Rs 30,000
GST (18 % on equipment): Rs 44,100
Subtotal (equipment + GST): Rs 2,39,100

Subsidy calculations (auto‑filled by SolarSwytch):

Central subsidy: Rs 78,000
Expected out‑of‑pocket for Arjun: Rs 1,61,100

The proposal also includes a payment schedule: 30 % advance, 40 % on‑site, 30 % after commissioning.

8. Contract Signing & Payment

Arjun signs the contract, pays the advance of Rs 48,330 (30 % of Rs 1,61,100). The remaining amount will be settled after the final inspection.

9. Installation & Commissioning

SolarTech’s team installs the panels, mounts the inverter, and connects the system to the BESCOM net‑metering meter. After wiring, they run a commissioning test that shows:

Peak output: 2.95 kW (close to rated)
Exported energy (first week): 120 kWh

A commissioning report (PDF) is generated and uploaded to the portal.

10. Post‑Installation Inspection

A BESCOM field officer visits Arjun’s house, checks the installation against the approved design, and signs off on the net‑metering setup. The officer uploads the inspection clearance to pmsuryaghar.gov.in.

11. Subsidy Disbursement

Within 10 working days of the inspection clearance, the central subsidy of Rs 78,000 is credited to Arjun’s bank account (Account No. XXXXXXXXXXXX). Arjun receives an SMS notification from the portal.

12. Claiming Karnataka State Top‑Up

Karnataka’s DISCOM website indicates a state top‑up of Rs 12,000 for systems between 2 kW and 3 kW. Arjun follows the DISCOM’s simple form, uploads the same documents, and receives the additional amount two weeks later.

13. Final Payment & Savings

After the state top‑up, Arjun’s total out‑of‑pocket reduces to Rs 1,49,100. Over the next 12 months, his electricity bill drops from an average of Rs 6,000 to Rs 2,000, saving Rs 4,000 per month (≈ Rs 48,000 per year).

14. Ongoing Monitoring

Arjun uses the inverter’s built‑in monitoring app to see real‑time generation. He also keeps a simple Excel sheet to record monthly bills and net‑metering credits.

Solar Subsidy Karnataka – Alternatives and Comparison

While the PM Surya Ghar Muft Bijli Yojana is the flagship central scheme, several other options exist for Indian homeowners. Below we compare the main alternatives on key parameters such as eligibility, subsidy amount, application complexity, and timeline.

Feature	PM Surya Ghar Muft Bijli Yojana (Central)	State‑Specific Rooftop Subsidy (e.g., Karnataka)	Private Financing (Solar Loans)	Self‑Financed (No Subsidy)
Eligibility	Residential only, valid electricity connection, roof ownership, no prior subsidy	Varies by state; often similar residential criteria plus income caps	Credit score, income proof; no subsidy eligibility needed	None
Subsidy Amount	Up to Rs 78,000 (30 kW for 2 kW + 18 kW for 1 kW)	Varies; some states add ₹10,000‑₹20,000 per kW, others offer flat top‑ups	None (but interest rates may be low)	None
Application Portal	pmsuryaghar.gov.in (single national portal)	State DISCOM portal or state energy department site	Bank or NBFC portal	N/A
DISCOM Involvement	Mandatory net‑metering agreement & inspection	Mandatory net‑metering; some states have faster clearance	Not required for net‑metering, but still needed for export	Net‑metering still required for grid‑connected systems
Processing Time	4‑8 weeks after inspection (central) + state top‑up time	2‑6 weeks (state) depending on bureaucracy	1‑3 weeks (loan approval)	Immediate (no paperwork)
Cash Flow Impact	Central subsidy credited after installation; state top‑up may arrive later	May receive state top‑up before or after central amount	Loan disbursement before installation; repayments start later	Full upfront cost
Complexity	Moderate – multiple steps, portal registration, DISCOM approval	Varies – some states have simplified forms, others more paperwork	Financial documentation but fewer government steps	Simple – just purchase and install
Long‑Term Savings	High – subsidy reduces capex, net‑metering credits lower bills	Additional state top‑up further improves ROI	Interest cost reduces net savings but still beneficial	Savings only from net‑metering credits
Typical Capex after Subsidy (3 kW system)	Approx. Rs 1.5‑1.6 Lakh (incl. GST)	May drop to Rs 1.3‑1.4 Lakh with state aid	Loan amount ≈ Rs 2 Lakh; interest adds ~10‑12 % over 5 years	Full cost ≈ Rs 2.4 Lakh

When to Choose the Central Scheme

You want the largest guaranteed subsidy without waiting for state approvals.
Your roof size fits the 3 kW sweet spot (maximum central subsidy).
You are comfortable handling the portal and DISCOM steps.

When a State Top‑Up May Be Better

Your state offers a higher per‑kW top‑up than Karnataka’s typical range.
The state portal integrates the central application, reducing duplicate work.
You prefer a single point of contact with the state energy department.

Private Financing vs. Subsidy

If you lack the cash to pay the out‑of‑pocket amount after subsidies, a solar loan can bridge the gap. While you forgo the direct cash benefit of a subsidy, many banks now offer interest‑free or low‑interest solar loans that are repaid from the monthly electricity savings.

Self‑Financed Installations

Some homeowners choose to pay the full amount upfront to avoid paperwork. This route is simplest but eliminates the significant cost reduction that the solar subsidy karnataka scheme provides.

Summary

Option	Best For	Approx. Net Cost (3 kW)
PM Surya Ghar + Karnataka Top‑Up	Homeowners who want maximum government support and can manage the portal process.	Rs 1.3‑1.5 Lakh
State‑Only Subsidy	Those whose state offers a higher top‑up and a streamlined process.	Rs 1.4‑1.6 Lakh
Solar Loan	Buyers with limited cash but good credit; willing to pay interest over time.	Rs 2.0‑2.2 Lakh (incl. interest)
Self‑Financed	DIY enthusiasts who prefer speed over savings.	Rs 2.4 Lakh

Choosing the right path depends on your financial situation, patience for paperwork, and the exact incentives your state provides. Always start by visiting pmsuryaghar.gov.in for the central scheme and then check Karnataka’s DISCOM website for any additional top‑ups.

Note: The comparison uses only the central subsidy figures provided in the official guidelines and does not include any unverified data.

Solar Subsidy Karnataka — rules, compliance and regulations

Eligibility checklist

Residential status – Only owner‑occupied houses qualify. Rental properties, commercial shops, and factories are excluded.
Electricity connection – A valid, active connection with the local DISCOM is mandatory.
Roof ownership – You must own the roof or have a written consent from the owner.
No prior subsidy – The applicant must not have received any central or state solar subsidy earlier.

Documentation required

Aadhar and PAN of the applicant.
Latest electricity bill (showing consumer number).
Proof of roof ownership (sale deed, lease agreement with consent).
Bank account details for subsidy credit.
GST registration of the installer (to be uploaded by the vendor).

DISCOM feasibility and net‑metering

The DISCOM conducts a technical feasibility study that checks roof size, orientation, shading, and load profile. Once approved, you must sign a net‑metering agreement that outlines:

Metering arrangement (bi‑directional meter).
Tariff for exported energy (usually same as consumption tariff).
Procedure for periodic inspection and billing.

Only after the net‑metering meter is installed and the system passes the DISCOM inspection will the subsidy be released.

Inspection and certification

A DISCOM inspector visits the site to verify:

Correct installation as per IEC standards.
Proper labeling of inverter and panels.
Safety clearances (fire, earthing).

The inspector signs a certificate of compliance, which is uploaded to the portal. Any deviation can lead to rejection or a demand for corrective work before subsidy release.

Disbursement timeline

After successful inspection, the portal triggers a direct bank transfer of the approved subsidy amount.
The applicant receives an SMS/email confirmation.
The transfer typically occurs within 10–15 working days, provided all documents are correct.

State top‑up considerations (Karnataka)

Karnataka may announce a state‑level top‑up on its DISCOM portal. The amount can vary each financial year and is subject to budget approval. Homeowners should:

Visit the Karnataka DISCOM website linked from pmsuryaghar.gov.in.
Check the latest circular for any additional cash benefit or extra free electricity units.

Never rely on unofficial sources for the top‑up figure.

Penalties for non‑compliance

Mis‑representation (e.g., claiming a commercial property) can lead to recovery of the subsidy and a penalty of up to Rs 1 lakh.
Failure to maintain net‑metering (e.g., disconnecting the system) may result in suspension of the subsidy and possible disconnection by the DISCOM.

Maintenance and warranty obligations

Installers must provide a minimum 2‑year warranty on workmanship and a 5‑year warranty on inverters.
Panel manufacturers usually offer a 10‑year product warranty and a 25‑year performance guarantee.
Regular cleaning and periodic performance checks are recommended to keep the system within the efficiency range required for net‑metering compliance.

Data privacy and portal security

All applicant data entered on pmsuryaghar.gov.in is encrypted and stored on government servers. Users should keep their login credentials confidential and avoid sharing OTPs with third parties.

Summary of compliance flow

Register on the portal → upload documents.
DISCOM feasibility → receive provisional approval.
Select a registered installer → sign net‑metering agreement.
Install system → DISCOM inspection.
Upload compliance certificate → subsidy credited.

Adhering strictly to these steps ensures a smooth experience and secures the full solar subsidy Karnataka benefit without legal hassles.

Frequently Asked Questions

What is the current solar subsidy karnataka homeowners can avail of?

Residents can access the central government subsidy under the PM Surya Ghar Muft Bijli Yojana. This provides Rs 30,000 per kW for the first 2 kW of installation. For systems between 2 and 3 kW, an additional Rs 18,000 per kW is provided. The total central subsidy is capped at Rs 78,000 for systems of 3 kW and above.

What is the total subsidy amount for a 3 kW solar system?

For a 3 kW system, the central subsidy is calculated in tiers. The first 2 kW receive Rs 30,000 per kW (total Rs 60,000). The third kW receives an additional Rs 18,000. Therefore, the total central subsidy for a 3 kW system is Rs 78,000, which is the maximum cap for the central government portion.

Is there a state top-up available for solar subsidy karnataka?

While the central government provides a fixed subsidy, state governments may offer additional top-ups. These amounts vary by state and are subject to change based on local policy. Homeowners are advised to check with their local DISCOM or visit the official state electricity portal to see if any additional state-level incentives apply.

What is the step-by-step process to get the subsidy?

The process begins with registration on the pmsuryaghar.gov.in portal. Once registered, the DISCOM provides feasibility approval. The homeowner then installs the system via a registered vendor. After installation, a net metering agreement is signed, followed by a technical inspection. Once approved, the subsidy is credited directly to the user’s bank account.

Do I need a net metering agreement for the subsidy?

Yes, a net metering agreement with the local DISCOM is a mandatory requirement. Net metering allows you to send excess electricity generated by your panels back to the grid. The subsidy will not be disbursed until the DISCOM verifies the installation and the net metering process is officially completed.

Can I use any solar installer for my project?

To be eligible for the subsidy, you must install your rooftop solar system through a registered vendor. These vendors are vetted and approved by the government to ensure that the equipment meets the required technical standards. Using an unregistered vendor may lead to the rejection of your subsidy application.

How do I check my PM Surya Ghar application status?

You can track the progress of your application by logging into your account on the national portal at pmsuryaghar.gov.in. The portal provides updates on feasibility approval, installation verification, and the status of the subsidy credit. For more detailed steps, you can read about PM Surya Ghar Application Status: How to Track Your Subsidy.

What documents are required for the application?

Typical requirements include a copy of your latest electricity bill to prove a valid connection, proof of roof ownership or legal rights to the roof, and a bank account passbook or cancelled cheque. This ensures the subsidy is transferred to the correct person and that the installation site is legal.

What happens if my system is larger than 3 kW?

If you install a system larger than 3 kW, the central subsidy remains capped at Rs 78,000. You will not receive additional central funds for any capacity beyond 3 kW. However, larger systems allow you to generate more electricity, which can further reduce your bills or increase your export to the grid.

How is the subsidy credited to the homeowner?

The subsidy is credited via Direct Benefit Transfer (DBT) directly into the bank account of the residential consumer. This happens after the DISCOM has inspected the system, verified the net meter installation, and submitted the completion report to the national portal.

Can I get a subsidy if I already have a solar system?

The scheme is generally for new installations. If you have already availed of a solar subsidy for your rooftop system in the past, you are not eligible for the PM Surya Ghar Muft Bijli Yojana. This ensures that the government benefits reach the maximum number of new households.

What are the technical requirements for the panels?

The panels and inverters must meet the technical specifications outlined by the Ministry of New and Renewable Energy (MNRE). Registered vendors typically handle this, as they provide equipment that complies with the standards required for DISCOM approval and subsidy disbursement.

How long does the feasibility approval take?

The timeframe for feasibility approval varies depending on the local DISCOM’s workload and processing speed. Once you apply on the national portal, the DISCOM reviews your electricity connection and roof space to confirm that the grid can handle the solar input before giving the green light.

Is the subsidy available for off-grid solar systems?

No, the PM Surya Ghar Muft Bijli Yojana is specifically for grid-connected rooftop systems. Off-grid systems, which rely solely on batteries and are not connected to the DISCOM grid, do not qualify for this central financial assistance.

What is the role of the DISCOM in the subsidy process?

The DISCOM acts as the primary verifier. They approve the technical feasibility of the site, verify the installation performed by the vendor, and install the net meter. Their final inspection report is the trigger that allows the central government to release the subsidy funds.

Can I apply for the subsidy if I am renting my house?

Generally, the applicant must have roof ownership rights. If you are a tenant, you would typically need the legal consent and documentation from the property owner to apply, as the installation involves permanent changes to the structure and long-term agreements with the DISCOM.

What is the difference between the first 2 kW and the 3rd kW subsidy?

The first 2 kW are subsidised at a higher rate of Rs 30,000 per kW to encourage small-scale adoption. The capacity between 2 kW and 3 kW is subsidised at a lower rate of Rs 18,000 per kW. This tiered structure prioritises basic energy needs for a larger number of homes.

Where can I find the most accurate subsidy amount for my specific system?

The most accurate information is available on the official government portal pmsuryaghar.gov.in. You can also find a detailed breakdown of the tiers in our guide on PM Surya Ghar Subsidy Amount Explained: Rs.30,000/kW to Rs.78,000.
