If you have a solar rooftop system or are planning to get one you’ve probably heard about net metering. But the actual process of getting it done through KSEB feels confusing to most people.
- Which form to submit first?
- How long does it take?
- What happens after installation?
This guide breaks down the complete KSEB net metering process step by step for 2026 in plain language, so you know exactly what to do and what to expect.
What Is Net Metering?
Net metering is a billing arrangement where your solar system is connected to the KSEB grid. When your solar panels produce more electricity than your home consumes, the surplus units are exported back to the grid. KSEB then adjusts those exported units against your electricity bill so you only pay for the “net” units consumed.
A bi-directional meter records both what you import from the grid and what you export back. This meter is the foundation of the entire net metering system.
Who Is Eligible for KSEB Net Metering in 2026?
Under the updated KSERC Renewable Energy Regulations 2025, effective from November 6, 2025, with the new billing system starting January 1, 2026 – here are the revised eligibility limits:
| Consumer Type | Net Metering Limit |
| Domestic (Residential) | Up to 20 kW |
| Industrial | Up to 500 kW |
| Agricultural | Up to 3,000 kW |
| Multi-storey Apartments (Common service) | Up to 500 kW |
Systems up to 10 kW are exempt from grid support charges under the new rules.

Documents You Need Before You Apply
Keep these ready before starting the process:
- Recent KSEB electricity bill (last 3 months)
- Consumer account number
- Property ownership proof
- Proposed solar system specifications
- BIS certificates of solar panels and inverter
- Layout diagram of the installation
KSEB Net Metering Process – Step by Step
Step 1: Assess Feasibility
Before submitting any application, evaluate your rooftop area and monthly electricity consumption. As a general rule, you need 60–80 sq. ft. per kW of solar capacity. This helps you size your system correctly so you don’t over-invest or under-utilise your rooftop.
Step 2: Submit Annexure-A (Feasibility Application)
Submit the Annexure-A form to your local KSEB office along with the application fee of ₹1,000.
KSEB completes the technical feasibility check within 15 days and confirms:
- Permissible system capacity
- Technical requirements for your connection
Step 3: Register on the KSEB Solar Rooftop Portal
Once feasibility is approved, register online at the KSEB ekiran portal. You can choose:
- Apply With Subsidy (PM Surya Ghar scheme)
- Apply Without Subsidy
Upload all required documents identity proof, property documents, and solar system details during registration.
Step 4: Submit Annexure-B (Detailed Registration)
Within 30 days of feasibility approval, submit the detailed registration application Annexure-B which includes:
- Technical system specifications
- BIS certificates for solar panels and inverter
- Layout diagrams
- Electrical system details
After KSEB verifies these documents and you pay the registration fee, KSEB issues your official registration number.
Step 5: Install the Solar System
After registration approval, you can begin installation. The system must be installed within one year of registration.
Ensure your installer is a KSEB or MNRE-approved vendor to avoid rejection during inspection.
Step 6: Get Electrical Inspector Approval
After installation, get your solar system inspected and certified by the Electrical Inspector (EI). This certificate confirms that your installation meets all safety and technical standards before KSEB conducts its own check.
Step 7: KSEB Testing and Net Metering Agreement
Submit the Electrical Inspector’s certificate to KSEB. KSEB then:old.kseb+1
- Conducts its own site verification
- Signs a formal Net Metering Agreement (Connection Agreement) with you
- This agreement defines your operational terms, safety compliance, and billing structure
The Net Metering Agreement is a mandatory document your system cannot go live without it.
Step 8: Bi-directional Meter Installation
After the agreement is signed, KSEB installs the bi-directional net meter within 10 days.
The meter is:
- Tested, verified, and sealed before commissioning
- Synchronized with the KSEB grid within 7 days of agreement signing
- Compliant with Central Electricity Authority (CEA) meter standards
Once the meter is live, your net metering billing begins from that date.

How Does Net Metering Billing Work?
Your KSEB bill under net metering is calculated as:
Units Consumed from Grid – Units Exported to Grid = Net Units Billed
You are charged only for the net units at the applicable KSEB tariff rate. Surplus exported units are credited not paid in cash and adjusted in subsequent billing cycles. Kerala Solar Subsidy 2026: The Complete KSEB & MNRE Guide
