On-Grid Solar System in Kadambur
TANGEDCO net metering, full PM Surya Ghar subsidy support, and honest pricing — for Kadambur homes and farm buildings connected to the grid.
An on-grid solar system in Kadambur is the most straightforward way for a household or farm building to slash its TANGEDCO bill without the added cost of batteries. Kadambur sits in the interior of Thoothukudi district — a compact rural settlement surrounded by dry-farming land where cotton, pulses and cereals grow under some of the fiercest sun in southern Tamil Nadu. That climate, which farmers know all too well from April through June, translates directly into outstanding solar generation figures. A well-oriented rooftop panel here produces around four to five units of electricity per installed kilowatt every single day, making the economics of grid-tied solar unusually favourable.
The on-grid model works by pairing your solar array with a grid-tied inverter that synchronises with the TANGEDCO supply. During daylight hours, your panels cover most or all of your household load — lights, fans, refrigerator, a water pump, perhaps a TV or mixer. When generation exceeds consumption, the surplus flows back into the grid and TANGEDCO credits those units to your account. At night, or on heavily overcast days, you draw from the grid as normal and spend those credits. The result, over a month, is a bill that can fall by up to ninety percent for a correctly sized system. There is no battery, no battery replacement cycle, and no additional complication — just a clean energy loop between your roof and the utility grid.
Green Point Solar is an MNRE-approved installer based in Kovilpatti, covering Kadambur and the wider Kovilpatti–Ettayapuram belt. We handle everything from the initial roof survey to the TANGEDCO net-metering application and the PM Surya Ghar subsidy registration. You do not need to navigate three different government portals or make repeated visits to the electricity board office — that is our job.
How TANGEDCO net metering works for Kadambur consumers
Net metering is the billing arrangement that makes on-grid solar viable. Once your system is commissioned and the TANGEDCO bi-directional meter is fitted at your service connection, the board records both what you import from the grid and what you export to it. Your monthly statement shows the net difference. If you exported more than you imported in a billing cycle, those surplus units roll forward as a credit — they are not lost. Over the year, most Kadambur households find that the summer months (when sun is abundant and farming activity slows) generate more than enough to offset the higher-consumption monsoon and winter periods.
TANGEDCO permits net metering for residential consumers up to a system capacity equal to their sanctioned load, and for most Kadambur homes that means a 1 kW to 5 kW system is perfectly within scope. Farm buildings with an agriculture service connection have a slightly different tariff category, and our team accounts for that during system design so the net-metering arrangement is correctly set up from day one.
Who benefits most from an on-grid system in Kadambur
The on-grid model suits the majority of Kadambur consumers — primarily because Kadambur, despite being a rural settlement, has a reasonably stable TANGEDCO supply for most of the year. If your property has a grid connection and your main concern is reducing the monthly bill rather than achieving total independence from the utility, on-grid is almost always the right starting point. Specific situations where it works particularly well include:
- Family homes with a regular daytime load — fans, lights, a pump and a refrigerator running through the day align naturally with the solar generation curve.
- Farm outbuildings with a domestic or LT connection — if the building has a metered TANGEDCO supply, an on-grid system can offset the lighting, pump motor and miscellaneous loads during the day.
- Small shops and commercial premises in Kadambur town — daytime trading hours overlap almost perfectly with peak solar hours, making the financial case very strong.
- Homes planning to avoid battery maintenance — batteries add upfront cost, periodic replacement cost and maintenance complexity; an on-grid system avoids all of that.
Kadambur's dry-farming climate — a solar advantage
The Kovilpatti–Ettayapuram belt is one of the driest micro-climates in Thoothukudi district. Kadambur's cotton and pulse fields depend on well-timed rainfall and whatever groundwater can be lifted during the dry months. That same low cloud cover and high direct radiation is what gives rooftop solar panels here more productive hours than systems installed further east toward the coast. The annual solar irradiation in this pocket runs close to 5.5–6 kWh per square metre per day — comfortably in the top bracket for Tamil Nadu — and that directly translates into more units, more credits, and a faster payback on your investment.
System sizes and what they cost in Kadambur
Gross system cost for an on-grid residential installation runs approximately ₹62,000 per kilowatt before subsidy. The PM Surya Ghar scheme reduces this substantially for homes: ₹30,000 per kW for the first two kilowatts and ₹18,000 for the third, with the maximum subsidy capped at ₹78,000 for a 3 kW or larger residential system. The table below gives an indicative picture — your exact quote depends on roof access, panel brand and inverter specification, all of which we confirm during the free site survey.
| System size | Typical daily generation | Best suited for | PM Surya Ghar subsidy |
|---|---|---|---|
| 1 kW | ~4–5 units | Very small home, minimal load | ₹30,000 |
| 2 kW | ~8–10 units | Average Kadambur family home | ₹60,000 |
| 3 kW | ~12–15 units | Larger home or AC load | ₹78,000 (maximum) |
| 5 kW+ | ~20–25 units | Shop, agri premises, large home | ₹78,000 (capped at 3 kW) |
PM Surya Ghar subsidy — what Kadambur homeowners need to know
The PM Surya Ghar: Muft Bijli Yojana is a central government programme that pays a direct subsidy into the homeowner's bank account after a grid-tied rooftop system is commissioned and the net meter is installed. The subsidy structure is ₹30,000 per kW for the first two kilowatts, and ₹18,000 for the third kilowatt — which means a 3 kW system attracts the maximum benefit of ₹78,000. Beyond 3 kW, the subsidy does not increase further for residential systems.
To receive this subsidy, the installation must be done by an empanelled vendor (Green Point Solar is MNRE-approved), the system must pass TANGEDCO inspection, and the net meter must be activated. Registration happens on the national PM Surya Ghar portal and requires your TANGEDCO consumer number, Aadhaar and bank details. We manage the entire portal submission on your behalf and alert you when the subsidy payment hits your account — typically within a few weeks of net-meter commissioning.
