On-Grid Solar System in Pasuvanthanai
TANGEDCO net metering, bill credits and full subsidy eligibility — on-grid solar explained for Pasuvanthanai homes and shops.
An on-grid solar system in Pasuvanthanai is the most popular solar configuration for households and small businesses with a reasonably stable TANGEDCO supply — and for good reason. It costs less than an off-grid or hybrid system because it has no battery bank, it qualifies in full for the PM Surya Ghar central subsidy, and it earns credits from the TANGEDCO net-metering scheme for every surplus unit your rooftop exports to the grid during daylight hours. When those export credits are netted against your nighttime import from the grid, the effective TNEB bill can drop by up to 90% — sometimes to just the fixed minimum monthly charge.
Understanding how the on-grid model works — specifically how net metering operates under TANGEDCO — helps you make an informed choice about whether this is the right configuration for your property in Pasuvanthanai. The system type that suits a home on a stable TANGEDCO feeder in Vilathikulam taluk may not suit a farm on the edge of the distribution network. This page covers the technology, the economics and the situations where on-grid solar delivers its best value.
How an on-grid solar system works
An on-grid system has three main components: the solar panel array on your roof, the grid-tied solar inverter, and the bidirectional meter installed by TANGEDCO at your point of connection to the grid.
- During daylight hours: Your panels generate DC electricity. The inverter converts this to AC and supplies your home's loads directly. If the solar generation exceeds your home's consumption at that moment, the surplus is exported through the bidirectional meter to the TANGEDCO grid.
- At night or during low-generation periods: Your home draws power from the TANGEDCO grid as normal, and the bidirectional meter records units imported.
- At the end of the billing period: TANGEDCO calculates your net consumption — units imported minus units exported. You pay only for the net import. If your exports exceed imports in a month, the credit carries forward to offset future bills.
- When there is a grid outage: On-grid inverters are required by safety regulations to shut down automatically when the grid goes down — this protects TANGEDCO linemen working on de-energised lines. The system does not provide backup power during outages.
On-grid solar and TANGEDCO net metering in Pasuvanthanai
Net metering in Tamil Nadu operates under TANGEDCO's regulations, which set out the technical specifications for interconnection, the bidirectional meter requirements, and the process for applying. We handle the complete TANGEDCO net-metering application for all our Pasuvanthanai customers — from the initial technical documentation to the inspection coordination and final agreement signing. Once TANGEDCO approves the connection and installs the bidirectional meter, your system is live and earning credits. The process takes standard TANGEDCO processing time; we follow up on your behalf throughout.
Who on-grid solar suits best in Pasuvanthanai
The on-grid configuration is the best choice when:
- Your TANGEDCO supply is reasonably reliable — you have power for most of the day and night, with occasional short outages rather than extended daily cuts.
- Your primary motivation is reducing your monthly TNEB bill, not providing backup power during outages.
- You want to maximise the financial return from the system, including claiming the PM Surya Ghar subsidy and the TANGEDCO net-metering export credits.
- Your property is a residential home — the PM Surya Ghar subsidy applies only to residential on-grid installations.
For farms or properties in Pasuvanthanai with less reliable supply, or where backup power for irrigation is essential, an off-grid or hybrid system with battery backup may be more appropriate. We assess each property individually and recommend the configuration that genuinely suits your situation — not just the most commonly installed system type.

How much does an on-grid system save on your TNEB bill?
The savings depend on your current monthly consumption, your TANGEDCO tariff category, and the size of your solar system. For a typical rural household in Pasuvanthanai consuming around 300–500 units per month, a 3 kW on-grid system generating approximately 390 units per month can reduce the net billed units significantly — and in many cases, the bill drops to just the fixed minimum charge, which is a reduction of 80 to 90% from the pre-solar level. Households that use more electricity — particularly those with pumps, air conditioning or additional appliances — will benefit from a larger system that can cover a higher proportion of their consumption.
