Kulithalai lies on the Cauvery at the eastern edge of Karur district, where the land is wetter and the economy more agricultural than industrial. Generation here is slightly below the western districts at about 4.25 units per kW, reflecting the greater cloud cover the river belt picks up during the north-east monsoon.
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.
This is banana and paddy country, and the electrical load reflects it: irrigation pumping above all, plus rice milling, cold storage for produce and the small trading premises of a market town. Pumping is the dominant draw and it is seasonal, concentrated in the dry months and lighter when the river and the monsoon do the work. That seasonality is the single most important fact in sizing a system here, and it is the thing most often got wrong by a quote prepared without seeing a year of bills.
Farm buildings are a mix of tiled and sheet roofs, often modest in area, and many properties have more usable open land than usable roof. Rice mills have larger sheds but also substantial dust, which affects both cleaning intervals and where an array should sit relative to the milling and husk-handling areas. For irrigation specifically, a ground-mounted array near the pump is usually simpler and cheaper than running cable from a distant rooftop.
At Kulithalai’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 4,650 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 Kulithalai section, Karur 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.
To the pattern across a full year, not to the peak irrigation month. A system built for peak demand sits idle through the wet season and exports surplus at the lower rate. Bring us twelve months of bills and the sizing follows from them.
For an irrigation-led system, usually near the pump. It avoids a long cable run and the losses that come with it, and ground mounting is easier to clean and extend. Where the premises also has a meaningful building load, a roof array may serve both.
Yes, noticeably — husk and bran dust settles faster than ordinary road dust and needs a shorter cleaning interval. Positioning the array away from the husk-handling end of the building helps more than any other single decision.
VENAARC installs across Kulithalai, 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.
