KSEB Rooftop Solar Application: Step-by-Step eKiran Portal & Net Metering Workflow

Q: How long does the complete KSEB solar application and net meter connection take?

From initial registration on eKiran to final bi-directional meter installation, the typical turnaround time in Kerala is 21 to 35 working days when managed end-to-end by an authorized EPC partner.

Q: Can I install a solar capacity higher than my KSEB sanctioned connected load?

No. Under KSERC regulations, solar plant capacity cannot exceed your sanctioned connected load. If your connected load is 3 kW and you require a 5 kW plant, GSR Energies will first process a Connected Load Enhancement application on your behalf.

Q: Do I need to pay any application fees to KSEB for rooftop solar?

A nominal registration and feasibility fee is payable online through the eKiran portal as per the prevailing KSERC tariff schedule.

Complete official step-by-step guide to applying for rooftop solar through KSEB's digital eKiran portal. Document checklist, technical feasibility approval, wiring completion certificates, and bi-directional meter testing.

Key Takeaways at a Glance

All residential and commercial rooftop solar applications in Kerala are processed digitally via KSEB's eKiran portal.
Technical feasibility clearance from the local KSEB Electrical Section verifies that distribution transformer capacity is adequate.
Approved solar vendors (such as GSR Energies) handle digital submissions, single-line diagrams (SLD), and electrical test certificates.
Bi-directional net meter procurement and laboratory testing ensure accurate export and import registration on consumer bills.
Integration with the National PM Surya Ghar portal ensures synchronous registration for central DBT subsidies.

Understanding the KSEB eKiran Renewable Energy Single Window

Under the direction of the Kerala State Electricity Regulatory Commission (KSERC), the Kerala State Electricity Board (KSEB) launched the eKiran web portal (ekiran.kseb.in) as a unified digital interface for grid-connected renewable energy systems.

Whether you are installing a 3 kW residential system under PM Surya Ghar or a 200 kW commercial captive plant, every rooftop solar installation connected to the Kerala grid must receive formal grid feasibility clearance and synchronization approval through eKiran.

—Single-Window Digital Verification: Tracks consumer identity, consumer number, section office code, and connected load.
—Distribution Transformer (DT) Load Checks: Ensures solar injection does not exceed 75% of the local distribution transformer capacity.
—Empanelled Vendor Integration: Allows authorized EPC partners like GSR Energies to upload technical wiring diagrams directly on behalf of consumers.

Mandatory Documents for KSEB Solar Application

Before initiating the digital application on eKiran, ensure the following valid documents are compiled. GSR Energies handles the preparation of technical drawings and compliance certificates.

Document Required	Issuing Authority / Source	Purpose in Application
Latest KSEB Electricity Bill	KSEB Consumer Portal / Section Bill	Verifies 13-digit consumer number & sanctioned load
Applicant Identity Proof (Aadhaar / Passport)	Government of India	Identity verification matching billing account name
Premises Ownership Document / Tax Receipt	Local Panchayat / Municipality / Corporation	Confirms legal right to install solar on the rooftop
Single Line Diagram (SLD) & Layout Plan	GSR Energies Electrical Engineering Team	Details module strings, inverter specs, AC/DC distribution & earthing
Solar Module & Inverter Datasheets	Hardware Manufacturer / ALMM Listing	Verifies DCR compliance, IEC 61215/61730 & IEC 62109 standards

Step-by-Step KSEB Application & Feasibility Approval Process

The entire installation lifecycle follows a structured regulatory workflow designed to protect grid stability and ensure safety.

Step 1 — Consumer Registration: Registration on ekiran.kseb.in linked with the 13-digit consumer number and National Portal registration number.

Step 2 — Technical Feasibility Clearance: The local KSEB Assistant Engineer (AE) inspects the distribution transformer loading and approves feasibility within 7 to 14 days.

Step 3 — Plant Execution & Installation: GSR Energies executes physical installation of Tier-1 TOPCon modules, inverters, structural mounting, and dual earthing pits.

Step 4 — Work Completion Certificate & SLD Submission: Submission of formal installation completion report signed by a licensed electrical supervisor along with CEIG clearance if applicable.

Bi-Directional Net Meter Testing, Inspection & Plant Energisation

Once the physical plant is installed, the existing unidirectional energy meter must be replaced with a dual-quadrant bi-directional net meter approved by KSEB (complying with IS 13779 / IS 14697 standards).

The net meter undergoes accuracy calibration and anti-islanding testing at KSEB's Meter Testing Laboratory (TMR Division). Following lab certification, KSEB technical staff visit the premises, verify the earthing pit resistance (< 5 ohms), verify the solar generation meter, program the time-of-day registers, and commission the plant.

Kerala Rooftop Solar & KSEB Implementation Impact

How these regulations, technical specifications, and standards apply specifically to homes and commercial setups connected to the Kerala State Electricity Board (KSEBL) grid:

Eliminates physical paperwork and multiple visits to KSEB section offices for Malappuram and Kozhikode consumers.
Transparent tracking of application milestones from feasibility query to formal commissioning certificate.
Standardized 21 to 30 day timeline from initial registration to meter energization when working with an experienced EPC.
