Government Solar Subsidy, Net Metering & Solar Loan Guide (India)

1. Making Solar Affordable with Govt Support

Installing a rooftop solar system in India has become more affordable than ever, thanks to a combination of Government of India subsidies, state-level incentives, net metering policies, and easy financing options from banks and NBFCs. What once required a substantial upfront investment can now be managed with minimal capital through solar loans and EMI plans, while the subsidy directly reduces your initial cost.

India aims to achieve 500 GW of renewable energy capacity by 2030, with a significant target for rooftop solar installations. The government has actively promoted residential rooftop solar through the PM Surya Ghar: Muft Bijli Yojana and other state-level schemes. These initiatives have made it possible for homeowners to install solar systems with little to no upfront cost and start saving on electricity bills from day one.

Understanding the full landscape of financial support available can be confusing. This guide brings together everything you need to know about the government solar subsidy, net metering, solar loans, and solar EMI plans in India, and shows you how to combine them for maximum savings. Whether you are a homeowner looking to reduce your electricity bill or a developer planning multiple installations, this comprehensive guide covers all the financial aspects of going solar.

2. Government Solar Subsidy for Residential Rooftop

Current Subsidy Rates (2026)

The Ministry of New and Renewable Energy (MNRE) provides a Central Financial Assistance (CFA) for residential rooftop solar installations under the PM Surya Ghar: Muft Bijli Yojana. The current subsidy structure is as follows:

• Up to 2 kW capacity: ₹30,000 per kW (total up to ₹60,000)
• 3 kW capacity: ₹30,000 per kW for the first 2 kW + ₹18,000 per kW for the third kW (total ₹78,000)
• Above 3 kW and up to 10 kW: ₹18,000 per kW for additional capacity beyond 3 kW (maximum subsidy ₹78,000 for 3 kW, then capped)
• For group housing societies (GHS): ₹18,000 per kW for common facilities up to 10 kW per house with a cap of ₹90,000 per kW for the overall system

It is important to note that the subsidy is applicable only for residential rooftop solar systems and not for commercial or industrial installations. The subsidy amount is directly credited to the bank account of the beneficiary through the DBT (Direct Benefit Transfer) mechanism.

Eligibility Criteria

To qualify for the government solar subsidy, you must meet the following conditions:

• The solar system must be installed by an empanelled vendor registered with the respective State Nodal Agency (SNA) or DISCOM
• Only Indian-made solar panels (manufactured in India) and inverters from the ALMM (Approved List of Models and Manufacturers) list are eligible
• Net metering or gross metering must be installed as per the applicable state policy
• The system capacity should not exceed the sanctioned load or the connected load of the premises
• Only residential properties (individual homes, apartments, group housing societies) are eligible
• The beneficiary must not have availed subsidy for any other solar system at the same premises previously

State-Wise Variations

Several states offer additional top-up subsidies on top of the central government subsidy. Here are some notable examples:

• Gujarat: Surya Urja Yojana offers additional state subsidy of ₹10,000–20,000 for residential rooftop
• Maharashtra: Additional state subsidy of up to ₹15,000 for 1–3 kW residential systems
• Tamil Nadu: Top-up subsidy of ₹10,000 per kW for residential consumers
• Karnataka: Surya Raitha Scheme with additional benefits for residential and agricultural consumers
• Uttar Pradesh: Additional subsidy of ₹10,000–15,000 under the UP Solar Policy
• Kerala: Surya Kerala scheme with attractive state-level incentives
• Delhi: Delhi Solar Policy offers generation-based incentives along with capital subsidy

Check with your local DISCOM or the State Nodal Agency for the latest subsidy rates applicable in your state. Our subsidy, loan and net metering page provides updated state-wise information.

3. How to Apply for Solar Subsidy

Step-by-Step Application Process

Applying for the government solar subsidy involves a structured process that connects you with your DISCOM and the National Portal for Rooftop Solar. Here is the complete step-by-step guide:

1. Register on the National Portal: Visit the National Portal for Rooftop Solar (solarrooftop.gov.in) and register as a consumer with your electricity bill details, mobile number, and email address.
2. Select an Empanelled Vendor: Choose a registered vendor from the list of DISCOM-empanelled solar installers in your area. Kanmani Renewables can assist you in identifying and working with the right vendor.
3. Submit Application: Log in to the portal, fill in the application form with your personal details, property documents, and vendor information. Upload the required documents.
4. Technical Feasibility Approval: Your DISCOM will review the application and conduct a technical feasibility study of your rooftop. This typically takes 7–15 days.
5. Installation: Once the feasibility is approved, your empanelled vendor will install the solar system. The installation should be completed within the stipulated timeline (usually 30–60 days from approval).
6. Net Meter Installation: After installation, the DISCOM will install a bi-directional net meter at your premises. The vendor will also apply for net metering on your behalf.
7. Commissioning Report: After successful commissioning and testing, the vendor submits the commissioning report on the portal along with photographs and test results.
8. Subsidy Disbursement: Once the DISCOM verifies the installation, the subsidy amount is directly credited to your registered bank account within 15–30 days via DBT.

Role of DISCOM

The DISCOM plays a crucial role in the entire subsidy process. They are responsible for technical feasibility assessment, net meter installation, inspection, commissioning verification, and recommending the subsidy disbursement. It is essential to maintain clear communication with your DISCOM throughout the process. Any delays in DISCOM approvals can affect the subsidy timeline, so we recommend working with an experienced installer like Kanmani Renewables who can manage the end-to-end process efficiently.

4. Net Metering Explained

How Net Metering Works

Net metering is a billing mechanism that allows you to export excess solar electricity generated by your rooftop system to the grid and receive credits for it. Here is how it works in simple terms:

During the day, your solar panels generate electricity. Your home consumes what it needs, and any surplus power is automatically exported to the grid through a bi-directional net meter. The net meter measures both the electricity you import from the grid and the electricity you export to the grid. At the end of each billing cycle, your electricity bill is calculated based on the net consumption — the difference between imported and exported units.

For example, if you export 400 units in a month and import 300 units, your net consumption is -100 units, meaning you have a credit. This credit is carried forward to the next billing cycle in most states. In some states with favourable policies, you may receive monetary compensation for excess generation at the end of the financial year.

Benefits of Net Metering

• Reduced electricity bills: With proper system sizing, you can reduce your monthly bill by 50–100%
• Fast payback period: Net metering accelerates your ROI, typically achieving payback in 3–5 years
• No battery required: Since the grid acts as your virtual battery, you do not need expensive battery storage
• Low maintenance: On-grid systems with net metering have minimal maintenance requirements
• Environmentally beneficial: Every unit of solar power exported reduces the need for fossil fuel-based generation

Eligibility and Capacity Limits

Net metering eligibility varies by state, but most states follow the MNRE guidelines. Typical eligibility criteria include:

• System capacity should not exceed the sanctioned load or connected load
• For residential consumers, system capacity is usually capped at 10 kW (some states allow up to 500 kW for commercial)
• The system must be grid-interactive with a certified grid-tie inverter that meets IEEE 1547 and IEC 61727 standards
• The consumer must have a 3-phase connection for systems above 5 kW (varies by DISCOM)

State-Wise Net Metering Policies

Net metering policies differ across Indian states. Some states have progressive policies while others impose restrictions such as seasonal net metering or monthly settlement. Here is a quick overview:

• Tamil Nadu: Net metering allowed up to 1 MW with annual settlement
• Maharashtra: Net metering up to 1 MW, monthly billing cycle
• Gujarat: Net metering up to 1 MW, settlement on annual basis with carry-forward
• Karnataka: Net metering allowed up to 1 MW for residential and up to 500 kW for commercial
• Uttar Pradesh: Net metering up to 500 kW with monthly net billing
• Delhi: Net metering up to 5 MW, one of the most progressive policies
• Rajasthan: Net metering for residential up to 10 kW, gross metering for larger systems

Some states have shifted to net feed-in or gross metering for larger systems. It is important to understand your state's specific policy before proceeding. Visit our detailed subsidy and net metering page for state-specific information.

5. Solar Loan and Financing Options

Banks Offering Solar Loans

Several public and private sector banks in India offer dedicated solar loans for rooftop solar installations. These loans cover the cost of solar panels, inverter, batteries, mounting structures, and installation charges. Some of the prominent banks offering solar loans include:

• State Bank of India (SBI): SBI Green Loan for rooftop solar up to ₹10 lakhs at competitive interest rates (usually 8.5–10.5% per annum)
• Punjab National Bank (PNB): PNB Surya Shakti Scheme for residential and commercial solar installations with flexible repayment tenure
• Bank of Baroda: Baroda Solar Loan with up to 80% financing and tenure up to 5 years

• ICICI Bank: Green Solar Loan with paperless processing and doorstep service
• HDFC Bank: Solar Equipment Loan with flexible EMI options and quick approval
• Axis Bank: Solar Loan programme offering up to ₹30 lakhs with collateral-free options

NBFCs Specialising in Solar Finance

Non-Banking Financial Companies (NBFCs) have emerged as key players in the solar financing space, often offering more flexible terms than traditional banks:

• Tata Capital: Solar equipment financing with customised solutions for residential customers
• Hero Fincorp: Solar loans with minimal documentation and fast disbursal
• Muthoot Finance: Gold-backed solar loans with lower interest rates
• Paisalo Digital: Small-ticket solar loans for rural and semi-urban households
• CreditAccess Grameen: Micro-solar loans for low-income households in rural areas

Interest Rates and Loan Terms

Solar loan interest rates typically range from 7.5% to 12% per annum, depending on the lender, loan amount, tenure, and your credit profile. Key parameters to consider:

• Loan Amount: Usually covers up to 80–100% of the total system cost
• Repayment Tenure: Typically 3–7 years, depending on the loan amount and lender
• Processing Fee: 0.5% to 2% of the loan amount
• Collateral: Most solar loans below ₹10 lakhs are collateral-free for residential customers
• Moratorium Period: Some lenders offer a 3–6 month moratorium before repayment begins

6. Solar EMI Plans

How Solar EMI Works

Solar EMI plans allow you to install a rooftop solar system with zero or minimal upfront payment and repay the cost in monthly instalments. The EMI structure is designed so that your monthly EMI is typically lower than or equal to your current electricity bill, meaning you start saving from day one. This is often called the "zero out-of-pocket" model for going solar.

For example, if your current monthly electricity bill is ₹3,000 and your solar system EMI is ₹2,500 per month, you save ₹500 from the first month itself. After the EMI period ends (typically 3–7 years), your electricity becomes virtually free for the remaining lifespan of the solar panels (25+ years).

Zero Down Payment Options

Many solar financing companies and NBFCs offer zero down payment solar EMI options. Under this model, the financier pays the entire system cost to the installer upfront, and you repay the amount in monthly instalments over an agreed tenure. This is particularly attractive for homeowners who do not have the capital to invest upfront but want to start saving on electricity immediately.

Zero down payment plans usually come with slightly higher interest rates (typically 10–14% per annum) compared to standard loans where you make a down payment. However, the convenience and reduced upfront burden make them highly popular for residential solar installations.

Repayment Tenure and EMI Calculation

The EMI for a solar system depends on the system cost, loan amount, interest rate, and tenure. Here is an indicative calculation for a 3 kW system costing approximately ₹1.8 lakhs (before subsidy):

• After subsidy (₹78,000): Net cost ₹1,02,000
• Loan amount: ₹1,02,000 (100% financing with zero down payment)
• Interest rate: 10% per annum
• Tenure: 5 years
• Monthly EMI: Approximately ₹2,170

With the solar system generating enough power to offset a monthly bill of ₹2,500–3,500, you can see immediate monthly savings of ₹300–1,300 from the first month itself.

7. Combining Subsidy + Loan + Net Metering for Maximum Savings

The real magic happens when you combine all three financial benefits — government solar subsidy, solar loan, and net metering — to create a financial structure that minimises your upfront cost and maximises long-term savings.

The Optimal Strategy

1. Apply for the subsidy first: Register on the National Portal and get your subsidy application approved before installation. This ensures you do not miss the deadline and the subsidy amount is locked.
2. Take a solar loan: After the subsidy approval, take a loan for the balance amount. The subsidy amount (up to ₹78,000 for 3 kW) directly reduces the principal loan amount, lowering your EMI.
3. Install and activate net metering: Once installed, get the net meter installed and activated immediately to start saving on your electricity bill from day one.
4. Use electricity savings to pay EMI: Your monthly electricity savings (typically ₹2,500–5,000 for a 3–5 kW system) can comfortably cover your EMI payments.

Sample Financial Model (3 kW System)

• Total system cost: ₹1,80,000
• Government subsidy: ₹78,000 (credited to your account)
• Loan amount needed: ₹1,02,000
• Monthly EMI (5 years @ 10%): ₹2,170
• Average monthly electricity savings: ₹3,000
• Net monthly saving during EMI period: ₹830
• Net monthly saving after EMI: ₹3,000
• Total savings over 25 years: ₹8–10 lakhs

8. DISCOM Approval Process

The DISCOM (Distribution Company) approval process is a critical step in installing a grid-connected solar system and availing net metering benefits. Understanding this process helps you avoid delays and ensure smooth installation.

Step-by-Step DISCOM Process

1. Application Submission: Submit the solar connection application to your local DISCOM office or through the online portal, along with the required documents and fee.
2. Technical Feasibility Study: The DISCOM assesses your rooftop for solar suitability, including structural integrity, shading analysis, and electrical infrastructure capacity. This typically takes 7–15 days.
3. Load Sanction: Based on the feasibility study, the DISCOM sanctions the additional solar generation load and issues a technical feasibility approval letter.
4. Agreement Signing: You need to sign a net metering agreement or power purchase agreement (PPA) with the DISCOM, outlining the terms of net metering.
5. Installation Inspection: After installation, the DISCOM inspects the system to verify compliance with standards, safety requirements, and approved specifications.
6. Net Meter Installation: The DISCOM installs a bi-directional net meter and seals it. This meter measures both import and export of electricity.
7. Commissioning Certificate: After successful testing, the DISCOM issues a commissioning certificate, and net metering billing begins from the next billing cycle.

The total DISCOM process takes 30–60 days from application to commissioning, depending on the state and DISCOM efficiency. Working with an experienced EPC company like Kanmani Renewables can significantly accelerate this process, as we manage all submissions, follow-ups, and coordination with the DISCOM on your behalf.

9. Documentation Required for Subsidy and Loan

For Solar Subsidy Application

• Aadhaar card of the applicant (for identity verification and DBT)
• PAN card of the applicant
• Latest electricity bill (showing consumer number, sanctioned load, and address)
• Property tax receipt or ownership proof (sale deed, registered lease agreement, or Khata certificate)
• Bank account details and cancelled cheque (for DBT credit of subsidy)
• Passport-size photograph of the applicant
• Mobile number registered with the DISCOM
• Vendor quotation and GST invoice from the empanelled installer
• Structural stability certificate for the rooftop (if required by DISCOM)
• NOC from the housing society (for apartment residents)

For Solar Loan Application

• KYC documents (Aadhaar, PAN, Voter ID, or Passport)
• Income proof: salary slips (last 3 months), bank statements (last 6 months), or IT returns (last 2 years)
• Property documents and address proof
• Quotation from the solar installer
• Subsidy approval letter (if already applied for subsidy)
• Existing loan statements (if any)
• Electricity bills for the last 3–6 months
• Business proof (for self-employed applicants)

Having these documents ready in advance can accelerate both the subsidy and loan processes significantly. Our team at Kanmani Renewables can guide you on the specific documentation required for your state and lender.

10. Common Mistakes to Avoid

When navigating the government solar subsidy, net metering, and solar loan processes, even small mistakes can lead to delays, reduced benefits, or outright rejection. Here are the most common pitfalls and how to avoid them:

1. Not checking vendor empanelment: Installing through a non-empanelled vendor disqualifies you from the subsidy. Always verify that your installer is registered with your state's SNA or DISCOM before proceeding.
2. Using non-ALMM panels: Only solar panels from the ALMM list qualify for subsidies. Ensure your installer uses compliant panels and inverters.
3. Submitting incomplete documentation: Incomplete applications are the leading cause of subsidy delays. Double-check all required documents before submission.
4. Ignoring state-specific policies: Net metering rules, subsidy top-ups, and DISCOM processes vary significantly between states. What works in one state may not apply in another.
5. Sizing the system incorrectly: An undersized system may not meet your needs, while an oversized one may not qualify for net metering. Conduct a proper load analysis before sizing your system.
6. Not applying for subsidy before installation: Some states require pre-approval before installation. Installing before approval can void your subsidy eligibility.
7. Skipping the technical feasibility study: Some homeowners install first and then discover their roof is unsuitable or the DISCOM cannot accommodate the load. Always get the feasibility check done first.
8. Choosing the cheapest vendor: Low-cost vendors may use substandard equipment, poor workmanship, or non-ALMM panels, which can affect both subsidy eligibility and system performance.
9. Not comparing loan options: Interest rates, processing fees, and terms vary widely across lenders. Compare at least 3–4 options before choosing a solar loan.
10. Ignoring maintenance after installation: Regular cleaning, monitoring, and maintenance are essential for maximising power generation and ensuring the system lasts 25+ years.

Avoiding these mistakes can save you months of delays and thousands of rupees. Our solar experts at Kanmani Renewables can help you navigate every step of the process correctly.
