What is TNEB Solar Bill Calculator?

The TNEB Solar Bill Calculator 2026 is a specialized tool designed for consumers in Tamil Nadu who use Solar Power. It helps you accurately calculate your electricity savings according to the new TANGEDCO guidelines.

There are two main billing mechanisms for solar connections in Tamil Nadu:

  • Net Metering: Applicable only for Domestic (Home) users. This involves unit-based adjustment.
  • Net Billing: For Commercial and Industrial users. This involves monetary adjustment (credit).
Important Note: It is difficult to calculate “Network Charges” and “Feed-in Tariff” manually. Our online solar calculator does this instantly for you.

Follow these simple steps to check your net bill:

Step 1 – Select Category: First, choose whether you are a Domestic (Home) or Commercial user.

Solar Bill FAQ

Net Metering is a unit-adjustment system. For example, if you consumed 200 units but generated 150 units via solar, you only pay for the remaining 50 units. Currently, this is available only for Domestic Connections.
This is for Commercial and other connections. Units are not deducted directly. Instead, TNEB charges full price for what you consume and pays a lower price (Feed-in Tariff) for what you export. The net amount is then billed.
Even if you have solar, you use TNEB’s poles and infrastructure. To maintain this, a small fee (Network Charge) is levied on every unit you generate. Domestic users have some concessions on this.
Don’t worry! If you generate more power than you consume (Surplus Energy), those units are credited to your account. You can carry forward this credit to adjust in the next month’s bill.
