In Rajasthan, if you have a rooftop solar system, your billing works under Net Metering for residential and small consumers. Here’s how the adjustment happens:
1. What is Net Metering?
You generate electricity from your solar panels.
First, that power is used in your home.
Extra (surplus) electricity goes to the DISCOM grid.
Your solar units exported are minus your units imported from the grid.
You pay only for the net units.
2. How Your Bill is Calculated?
Your BIDHLI bill shows three important readings:
1. Import Units
Electricity you take from DISCOM
(Example: 150 units)
2. Export Units
Extra solar electricity you give to the grid
(Example: 200 units)
3. Net Units = Import – Export
Here:
150 (Import) – 200 (Export) = –50 units
If net units are negative, you get a credit.
3. Monthly Adjustment
✔ If Export > Import
You pay only the fixed charges.
Extra units are carried forward as credit to next month.
✔ If Import > Export
You pay for the difference units as per tariff.
4. Yearly Settlement (March Closing)
At the end of financial year:
Remaining credit units are settled by DISCOM.
They pay you at Average Power Purchase Cost (APPC)
(Approx ₹3–4/unit depending on year).
Example (Simple Calculation)
Month:
Import: 120 units
Export:170 units
Net: 120 – 170 = –50 units
You have 50 units credit and bill = only fixed charges.
Where It Shows on Bill?
In Rajasthan DISCOM bill, look for:
Solar Export (kWh)
Solar Import (kWh)
Net Consumption / Net Billing
Credit Carried Forward
