TANGEDCO Net Metering Application 2026: Step-by-Step Guide by SVT Solar
Installing a rooftop solar system is one of the most effective ways for homeowners and businesses in Tamil Nadu to reduce their dependence on conventional electricity and lower long-term power costs. However, for a grid-connected solar system, installing the panels is only one part of the process. The system must also be connected to the electricity grid through the appropriate metering and approval process.
The TANGEDCO Net Metering Application 2026 process allows eligible consumers to apply for rooftop solar connectivity and a net meter through the Unified Solar Rooftop Portal. The official portal currently provides online options for solar rooftop applications, including subsidy and non-subsidy applications, as well as applications for net-meter installation.
If you are planning to install rooftop solar in Tamil Nadu, understanding the application procedure can help you avoid unnecessary delays. This guide explains the process in simple steps and highlights the important documents, approvals and precautions to consider.
What Is Solar Net Metering?
Solar net metering is a system that allows a grid-connected rooftop solar installation to export surplus electricity to the electricity grid.
During the daytime, solar panels generate electricity that can be used directly by the property. If the solar system produces more electricity than the property consumes at that moment, the surplus can be exported to the grid through a suitable bidirectional meter.
When solar generation is insufficient, electricity can be drawn from the grid as usual.
The meter records electricity flowing in both directions, helping the electricity distribution utility account for imported and exported energy according to the applicable rules and regulations.
