Karur exports home textiles to the world — bedsheets, towels, curtains and made-ups that leave here for European and American retailers — and that export orientation changes the conversation about solar in a way nothing else in our service area does. Buyers increasingly ask suppliers to account for the energy behind the product, and a rooftop array is one of the few answers a mid-sized unit can give without changing how it manufactures.
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.
The home-textile trade runs stitching units, processing houses and packing operations, most on day shifts with a load that holds steady through working hours. Alongside it sits bus and lorry body building, a trade Karur shares with Namakkal, and a paper-mill presence along the Amaravathi. For the textile units the commercial case and the compliance case point the same way: generation covers daytime demand at the full tariff, and the same installation supports the sustainability reporting that export buyers increasingly require. That second benefit is real but should not be oversold — it supports a claim about purchased electricity, not a carbon-neutral product.
Stitching floors are typically wide-span sheet roofs with good clear area and skylights spaced through them; the skylights are the main constraint on layout, and working around them rather than over them keeps the floor usable. Processing houses carry the same vapour considerations as any wet-process textile site. Packing and warehouse sheds are often the best surfaces on a campus — large, unshaded and structurally simple — and are worth assessing even when the production building is the obvious candidate.
At Karur’s average yield, a 3 kW rooftop system — the size the PM Surya Ghar subsidy caps at — generates roughly 12.8 units on an average day and about 4,680 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 Karur distribution 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.
Honestly stated: that a measured share of your electricity is generated on site, with metered figures to back it. That is a defensible and useful claim. It is not carbon neutrality and it does not cover the energy embedded in your yarn or fabric, and we would rather you quote the real number than an ambitious one that does not survive an audit.
It depends on roof area against daytime consumption. For a typical stitching unit with reasonable roof, a meaningful share of daytime demand is achievable; for a processing house with heavy thermal load, proportionally less. The survey gives you a number from your own bills rather than an industry average.
They constrain the layout rather than prevent the system. We lay the array out around them so the floor keeps its daylight — covering skylights to fit more panels trades one benefit for another and is rarely worth it.
No, though a first survey is scheduled rather than immediate. Installation and later service calls are routine at this distance; it is well inside the area we cover from Sankagiri.
VENAARC installs across Karur 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.
