Sankagiri is where VENAARC is based, so this is the one town where our survey, installation and service response is same-day rather than scheduled. The town sits beneath the hill fort on the Salem-Erode road, and its position on the NH-544 corridor is why it has grown into a transport and warehousing stop rather than a manufacturing centre.
Yield figures are regional averages from published irradiance data, quoted as indicative ranges. What a particular roof produces depends on its orientation, shading and the equipment specified — which is what the site survey establishes.
Sankagiri is a lorry town. The transport yards, tyre and body-building workshops and the warehousing that serves the Salem-Erode highway dominate local demand, and their load is daytime and compressor-heavy. Warehouse roofs here are large, unshaded and structurally simple, which makes them some of the most straightforward solar sites in the district. The surrounding blocks are agricultural, where the relevant load is borewell pumping rather than premises supply.
Warehouse and transport-yard roofs around Sankagiri are mostly long-span galvanised sheet with good orientation and almost no shading obstruction - close to ideal. Housing in the town is a mix of flat RCC and Mangalore-tile pitched roofs; tiled roofs need a rafter-fixed mount and a more careful leak-proofing detail than an RCC slab, which we handle with flashed penetrations rather than sealant alone.
At Sankagiri’s average yield, a 3 kW rooftop system — the size the PM Surya Ghar subsidy caps at — generates roughly 13 units on an average day and about 4,730 units a year. Residential rooftops of 3 kW and above qualify for the central subsidy of up to ₹78,000, subject to eligibility under the scheme, and Tamil Nadu announced a further top-up in September 2026 — our solar subsidy guide sets out what each one pays and how firm the state figure is.
Net metering is handled through Sankagiri section, Salem circle. We prepare and file that application as part of the installation; sanction typically takes 60 to 120 days from submission. Our net metering guide explains which arrangement you would be on and why it decides the size worth installing.
Practically, yes. Survey visits are same-day rather than scheduled around travel, and if something needs attention after commissioning there is no travel window to wait for. Everything else - the equipment, the subsidy process, the TNPDCL paperwork - is identical to any other site.
Yes. Mangalore-tile roofs are common in Sankagiri and take a rafter-fixed mount with properly flashed penetrations. It is more labour than a flat RCC slab and the survey matters more, because the rafter condition decides the fixing plan.
Agricultural pumping is a different system from a rooftop one - it is sized to the pump and the daily water requirement rather than to a electricity bill, and it may not involve the grid at all. Tell us the pump rating and depth and we will tell you honestly whether it is worth doing.
VENAARC installs across Sankagiri, Salem district from our base in Sankagiri. Listing an area means we travel there and work there — it is not a claim that a plant has been built in every town named on this site.
The survey is free and there is no quote until someone has seen the roof. Call +91 7871631474 or send the details and we will come out to you.
