Solar Panel on Terrace: Permissions Guide 2026

You need three core approvals to legally install rooftop solar in India: a DISCOM feasibility approval, a net metering agreement, and a Chief Electrical Inspector (CEI) commissioning certificate.

If you live in a housing society or are a tenant, you also need a society or landlord NOC before you apply.

TL;DR

• You cannot connect a solar system to the grid without DISCOM approval. No approval means no subsidy and no net metering.

• The full approval process takes 30 to 60 days if documents are in order.

• Society NOC is mandatory if you live in an apartment or do not own the terrace outright.

• PM Surya Ghar Yojana (2026) offers subsidies up to ₹78,000 for systems up to 3 kW. Check your full solar subsidy under PM Surya Ghar eligibility before you apply.

• You can apply on pmsuryaghar.gov.in

  and track your approval status online.

Why the Permission Stage Confuses Most Homeowners

Most people skip the paperwork research and call an installer first. That is the wrong sequence.

Getting your approvals in order before installation protects your subsidy claim and ensures your system is legally commissioned.

Installing without DISCOM sanction means your excess units cannot flow back to the grid, and your subsidy gets blocked.

If you are still deciding between system types, read our guide on on-grid vs off-grid vs hybrid solar before you proceed.

The 4 Key Approvals You Need

1. DISCOM Feasibility Approval (Technical Sanction)

This is the first and most important step. Your local DISCOM (Distribution Company) inspects your site and confirms the grid can handle your system capacity.

The approval confirms:

• Your sanctioned load against proposed solar capacity

• Transformer capacity at your connection point

• Technical compatibility of your proposed system

By regulation, DISCOM must complete this feasibility check within 30 days of your application.

How to apply: Register on pmsuryaghar.gov.in or your state DISCOM's portal, enter your consumer number, proposed system size, and upload basic documents.

2. Net Metering Agreement

Once you get feasibility approval, you sign a net metering agreement with your DISCOM. This is your legal contract that governs how exported energy is billed.

Learn more about how net metering works and earns you income from your rooftop system.

Key points in the agreement:

• Your billing cycle under net metering

• Energy export and import terms

• DISCOM access rights to your meter

• Safety and shutdown compliance

The agreement is typically on stamp paper and must be signed within the DISCOM's stipulated window.

The Ministry of Power has directed all states in 2025 to move toward standardized digital net metering agreements to remove delays that previously ranged from 2 weeks to 6 months.

3. CEI (Chief Electrical Inspector) Certificate

For systems above 10 kW, most states require a commissioning certificate from the Chief Electrical Inspector or the state electrical authority.

This certificate confirms:

• Safe installation by a certified technician

• Electrical compliance as per state regulations

• Readiness for grid synchronization

Residential systems under 10 kW typically bypass this step, but check your state's specific rule before finalizing.

4. MNRE Vendor Registration Compliance

• You must install through a vendor registered on the MNRE national portal to be eligible for the PM Surya Ghar subsidy.

• Unregistered vendors = no subsidy eligibility. Verify your installer's MNRE registration number before signing any contract.

When Do You Need a Society or Landlord NOC?

A society or landlord NOC is mandatory in three scenarios. Read our complete apartment solar installation guide if you are in a multi-floor building.

The NOC should be on stamp paper and must clearly mention the address, system capacity, and consent for grid connectivity.

Tip: Get the NOC before you apply to DISCOM. It is a required attachment in most DISCOM application portals.

3. Submit feasibility application

   with all documents and pay the processing fee (usually a few hundred rupees)

4. Wait for DISCOM site inspection

   (within 30 days by regulation)

5. Receive Technical Sanction / Feasibility Approval Letter

6. Engage an MNRE-registered vendor

   to install the system

7. Sign the net metering agreement

   on stamp paper

8. DISCOM installs the bi-directional net meter

   at your premises

9. Get CEI certificate

   (if applicable for your system size)

10. Submit plant commissioning details

    on the portal to trigger subsidy disbursement

Important 2026 Regulatory Update: DCR Modules Now Mandatory

From 1 June 2026, all grid-connected solar systems in India must use DCR (Domestic Content Requirement) modules. This directly affects your solar panel cost in India and budgeting.

This applies to:

• PM Surya Ghar installations

• Net-metering rooftop projects

• Open access and KUSUM installations

Non-DCR modules will not qualify for subsidy or net metering after this date.

If you are planning to install before June 2026, you can still lock in current pricing before costs increase by approximately ₹8 to ₹10 per Watt.

State-Specific Notes

The core process is the same across India, but state-level variations exist. Gujarat homeowners should read the full Gujarat Rooftop Solar Policy 2026 for state-specific rules.

5 Frequently Asked Questions

Q1. Is it mandatory to get a DISCOM NOC before installing solar panels in India?

Yes. You must receive technical feasibility approval from your local DISCOM before installing a grid-connected solar system. Installing without it means your system cannot be connected to the grid, and you lose all subsidy eligibility under PM Surya Ghar.

Q2. Can I install rooftop solar if I live in a rented apartment?

Yes, but you need a notarized NOC from your landlord allowing the installation and grid connectivity. Your DISCOM application will not be processed without it. Read our apartment solar installation guide for a full walkthrough.

Q3. How long does the full DISCOM approval process take?

The DISCOM feasibility check should be completed within 30 days by regulation. Registration and sanction take another 10 to 15 days. Total process from application to meter installation is typically 45 to 60 days if your documents are complete.

Q4. What is the subsidy available under PM Surya Ghar Yojana in 2026?

The scheme offers a central subsidy of up to ₹78,000 for a 3 kW system. It provides up to 300 units of free electricity per month. Check the full solar subsidy breakdown for Gujarat 2026 for exact figures and eligibility.

Q5. Do I need a building permit or municipal permission for rooftop solar in India?

For most residential rooftop systems, no separate building permit is required from the municipal body. However, in Delhi, DDA or MCD permission for terrace use may be needed. Always verify with your local DISCOM and municipal body before applying.
