Solar Panel Installation in Dharmapuri
Dharmapuri runs on two things that could hardly be less alike: granite, which is dusty, heavy and year-round, and mango, which is clean, light and over in ten weeks. Both are worth solar and they need to be sized completely differently. Roofs here see about 4.29 units per kW on an average day, and the district sits 91 km up the road from Sankagiri.
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.
What we install in Dharmapuri, and for whom
Granite quarrying and cutting is the steady load — gang saws, polishing lines, slurry pumps and compressors, mostly running through the working day at a level that barely moves from month to month. That consistency makes it one of the easier industrial loads to size against. Mango pulp processing is the opposite: the units run hard from May into July and then sit idle for most of the year, so sizing against peak-season demand produces an array that spends three-quarters of its life exporting at the export rate rather than displacing consumption at the tariff. Sericulture rearing sheds and the chilling centres that serve the dairy trade add small, steady loads, and the chilling centres in particular run through the night, which solar alone does not cover.
Roofs in Dharmapuri
Granite cutting sheds are often partially open by design — the work is wet and the sheds are built to ventilate — so the usable roof is smaller than the building footprint suggests, and the slurry dust settles on everything nearby. That dust is the practical point: panels at a cutting unit need cleaning more often than panels anywhere else in our area, and an array sited upwind of the saws will stay cleaner than one directly over them. Pulp units have good clean sheet roofs. Farm and sericulture buildings tend to be small and tiled, where a ground-mounted array on spare land is usually the better answer than fighting a modest roof.
A 3 kW system here
At Dharmapuri’s average yield, a 3 kW rooftop system — the size the PM Surya Ghar subsidy caps at — generates roughly 12.9 units on an average day and about 4,700 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 Dharmapuri 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.
Questions people in Dharmapuri ask
Our pulp unit only runs in the season. Is solar still worth it?
Yes, but sized for the whole year rather than for June. If we size against peak-season consumption you get an array that is idle most of the year and exports its output at the export rate, which is well below what you pay for a unit. Sizing against your year-round base load — offices, cold storage, lighting, any processing that continues — gives a smaller system with a better return. We would rather sell you the smaller one.
How much does granite dust affect output?
Enough to plan around. Soiling on a dusty site can cost a meaningful share of output between cleanings, which is why cleaning intervals at a cutting unit should be shorter than the general advice and why where the array sits relative to the saws matters. None of it is a reason not to install; it is a reason to budget for maintenance honestly rather than assume a fit-and-forget system.
Can solar run our milk chilling centre overnight?
Not on its own. Chilling runs when the sun does not, so a grid-tied array offsets your daytime draw and the night load still comes from the grid. Batteries would cover it and would roughly change the cost of the project, so for most chilling centres the sensible answer is to take the daytime saving and leave the nights alone.
Is 91 km too far for you to service properly?
No. It is a comfortable day trip from Sankagiri and well inside the area crews cover routinely. The first survey is scheduled rather than same-day; everything after that works the way it does closer to home.
