How the process works
1. Online application on the KSEB Anert portal with consumer number, load details and Aadhaar. 2. Technical feasibility study by the local KSEB section office (5–7 days). 3. Approval letter issued; installation begins. 4. Synchronisation test by KSEB engineer. 5. Bi-directional net meter installed and sealed. 6. PPA (Power Purchase Agreement) signed; system goes live.
Settlement and billing
Every month KSEB issues a net bill — units imported minus units exported. Surplus carries forward. Once a year (April–March cycle), any leftover surplus is settled in cash at the prevailing APPC rate. Fixed charges and meter rent continue to apply.
Why use a KSEB-empanelled installer
KSEB only releases net-meter approval and PM Surya Ghar subsidy disbursal for systems installed by empanelled vendors with proper test certificates. Mastride is empanelled across all KSEB sections in Kerala, so your application moves without rework.
Frequently asked questions
+What is KSEB net metering?
Net metering replaces your standard KSEB meter with a bi-directional one. Solar units you export during the day offset units you import at night, and KSEB bills you only for the net difference at the end of each month.
+How long does net-meter approval take in Kerala?
From application to commissioning, expect 3–5 weeks: 5–7 days for feasibility approval, 7–10 days for installation, 7–10 days for KSEB inspection and net-meter installation.
+Is there a load limit?
Domestic single-phase: up to 5 kW. Domestic three-phase: up to 10 kW. LT-commercial: up to 150 kW. HT: up to 1 MW. Systems above these limits require Open Access or behind-the-meter approval.
+What does net metering cost?
KSEB charges a one-time net-meter fee of ~₹4,500–8,500 depending on phase and capacity. Mastride includes this in the all-inclusive quote.
+What happens to surplus units?
Surplus units roll forward month to month and are settled at the end of the KSEB financial year (March 31). Unused surplus is paid out at the APPC rate (~₹3.05/unit for FY 2026).
