# Solar net-metering bill in Madhya Pradesh

## How does net-metering work on an MPPKVVCL electricity bill?
A net-metering connection has two readings: import (energy drawn from the grid) and export (energy fed back to the grid by your rooftop solar). Net consumption = Import - Export. You are billed only for the net. If you exported more than you imported in a month, the excess is banked forward as a credit for future months.

## What is banking carry-forward on a solar bill?
Banking carry-forward is the unused export credit from one month carried to the next. For example, if in March you exported 200 units and imported 150 units, your 50-unit net export is banked. In April, that 50 units reduces your net import before billing. bijlibillwala checks banking continuity month-to-month and flags any discontinuity.

## Why is my solar credit smaller than I expected?
Five common reasons: (1) the export meter reading is wrong, (2) the bill applied the wrong export rate, (3) the previous month's banking carry-forward was not brought forward, (4) the bill treated solar units as import instead of export, (5) the connection's net-metering status was reset during a tariff change. bijlibillwala checks each one.

## How is the export rate calculated for rooftop solar in MP?
MPPKVVCL applies the gross export rate published in the most recent MPERC tariff order for net-metering consumers. The rate is updated annually with the tariff order; verify against the LV-1.2 schedule on mperc.in. bijlibillwala compares the applied rate against the latest MPERC order on every bill.

## What if the export meter reading is missing on my bill?
A missing or zero export reading on a known net-metering connection is a critical billing error. Raise it immediately via 1912 helpline and follow up with a written complaint to your AE/EE. The MPPKVVCL meter reader must record both meters every month for a net-metering connection.

## Can banked solar credit expire?
Under current MPERC regulations, banked solar credit carries forward through the financial year and is settled at the end of the year (March). Unutilised banked units at year-end are typically paid out at a settlement rate or written off depending on the connection category. Verify the exact treatment in the MPERC Net-Metering Regulations for your connection type.

## Does bijlibillwala work for both rooftop solar and gross-metering?
bijlibillwala is designed for net-metering (the default for residential and small commercial rooftop solar in MP). Gross-metering, where 100% of generated solar is sold to the grid and 100% of consumption is bought separately, follows a different accounting flow not yet supported in bijlibillwala v1.

## What should I do if my solar bill has discrepancies?
Generate the bijlibillwala grievance packet (it includes import, export, net consumption, banking carry-forward with exact numbers per month), call 1912 first, and follow up with a written complaint to your AE/EE. Solar billing errors often span multiple months because of banking carry-forward — include at least the last 6 bills in the grievance.
