Solar Panel Installation in Irungattukottai
Allotment terms checked before design, so nothing stalls at approval stage
Irungattukottai is a managed SIPCOT park, and that changes one thing fundamentally: most units here occupy allotted plots on long lease rather than freehold land. Before a roof gets measured, the question is what your allotment terms say about permanent structures.

Subsidy and TANGEDCO paperwork filed by us
Free site survey and energy audit, no obligation
The short answer
Looking for a solar panel installation company in Irungattukottai?
Irungattukottai is industrial, and a factory roof is a structural question first: purlin spacing and sheet condition decide the design before any panel is chosen. Air here carries more dust than most of the city, which means soiling losses and a cleaning schedule worth quoting honestly. Installing across Chennai since 2020, we file the PM Surya Ghar application worth up to ₹78,000 for households, handle TANGEDCO net metering end to end, and cover two years of maintenance after commissioning. Before the survey, you can check the solar panel price in Chennai for 3 kW to 10 kW systems and see how our solar panel installation in Chennai works, the same process we follow in Irungattukottai.

The local picture
Allotted plots and what you can build on them
Units in a SIPCOT industrial park typically occupy allotted plots held on long lease rather than owned outright, and allotment conditions frequently govern what may be built, altered or added on the plot. A rooftop solar array is a permanent structure with a 25-year design life, so establishing your position under the allotment terms is the first step, ahead of any technical assessment.
What to check before design
Your allotment or lease conditions
And whether they require approval for structural additions.
Remaining lease tenure against a 25-year asset
Where tenure is comfortable, ownership makes sense. Where it is not, the position at expiry should be documented.
Any park-level requirements
On external appearance, roof loading or electrical alterations.
Whether the building is yours or sub-leased from another allottee
Which adds a second layer of permission.
We raise this in the first conversation
It is quicker to check a document than to reverse a design
Rather than at the survey, because it determines whether the project proceeds at all.
The technical picture is standard industrial
Sheet roofs, and sizing to self-consumption
Profiled metal sheet roofs over steel purlins, where purlin spacing, frame load capacity and sheeting condition determine the design. Many units here are relatively young, so sheeting condition is less often the blocking question than in older estates. Non-domestic consumers are generally on net feed-in, so size to daytime self-consumption, and solar reduces the energy charge rather than the demand charge.

Local guide
Irungattukottai factory roofs: sizing solar against the park's anchor plant
Hyundai Motor India opened its first plant at Irungattukottai in 1998, and it now has a capacity of 8,50,000 vehicles a year. Its own rooftop project gives SIPCOT units here a useful local benchmark for how much roof a kilowatt really takes.
A roof area benchmark from the park's largest plant
Hyundai was installing a 1.9 MWp rooftop system on a module factory roof of 13,028 sq m. That works out to about 7 sq m of roof per kW, or roughly 74 sq ft, including walkways and gaps. Use it as a first check before any survey: a clear sheet roof of 1,000 sq m can carry roughly 140 to 145 kW, subject to purlin capacity and sheeting condition. At the Kancheepuram yield of 1,600 units per kW a year, 140 kW would make about 2,24,000 units a year. Whether that much is worth installing depends on how much of it your unit uses in working hours. A roof with skylights every few bays loses part of that area, so measure the clear zones, not the gross roof.
Rooftop for the base, open access for the rest
Hyundai's Indian operation said that in 2022 it received about 85% of its electricity as green power from external plants, with rooftop solar on top. The same logic applies at smaller scale. A rooftop array covers part of a daytime load. Units whose consumption is many times what their roof can supply should look at captive or open access solar for the balance, and use the roof for the share it can serve directly. Rooftop exports from a non-domestic connection earn only ₹3.61 a unit up to 10 kW and ₹3.37 from 11 to 150 kW, so the roof should be sized to self-consumption. The first step is twelve months of bills, which show the daytime share of your load.
Homes in the villages around the park
Workforce housing in the surrounding villages is mostly independent houses, and many rooms and houses are let to workers. The subsidies go to the person whose name is on the electricity connection, so in a let house the owner, not the tenant, decides on solar. At 1,600 units per kW a year, a 3 kW system makes about 4,800 units a year, and it costs about ₹2,10,000 before subsidy and about ₹1,10,000 after both subsidies. These houses are well inland, but dust from heavy park traffic means cleaning every two to three weeks in the dry months. Homes above 4 kW need three-phase supply, which can be filed alongside net metering.

- No obligation at any point. If solar does not make sense for your property, we will say so.
Common questions
Solar in Irungattukottai, common questions
Can a SIPCOT unit install rooftop solar on an allotted plot?
Usually, but the allotment conditions come first. Units typically occupy plots held on long lease rather than freehold, and those conditions frequently govern what may be built or altered. A solar array is a permanent structure with a 25-year design life, so we check your allotment terms and any park-level requirements before a roof is measured.
Does remaining lease tenure affect the decision?
Yes. Where tenure comfortably exceeds the asset life, ownership makes sense. Where it does not, the position at expiry should be documented before installation, and an OPEX or RESCO structure aligned to the remaining term sometimes compares better than ownership.
How should an Irungattukottai unit size its system?
To daytime self-consumption rather than available roof. Non-domestic consumers are generally on net feed-in rather than one-for-one net metering, so exported units earn well below the tariff paid on imports. Solar also reduces the energy charge rather than the demand charge, which on an HT connection remains substantial.
How long does installation take in Irungattukottai?
Eight to fourteen weeks for the industrial and commercial connections typical of Irungattukottai, against six to ten for a home. HT connections need more approval steps, and the work is usually phased around your shifts rather than done in one run.
Do you handle the subsidy and TANGEDCO paperwork?
Yes for residential connections. Note that the PM Surya Ghar subsidy does not apply to commercial or industrial connections, which is the position for most properties in Irungattukottai. For those we file the TANGEDCO net feed-in application and provide the documentation your accountant needs for accelerated depreciation instead.
What is included after installation?
Two years of free maintenance from commissioning, covering panel cleaning, annual inspection of connections and structure, generation monitoring and warranty coordination with the manufacturer.
How much roof does a SIPCOT unit in Irungattukottai need per kW?
About 7 sq m per kW on a clear sheet roof, based on Hyundai's 1.9 MWp system on 13,028 sq m. Skylights, ridge vents and walkways reduce what is usable. The purlin spacing and frame capacity then decide whether that area can carry the load.
Can an Irungattukottai factory combine rooftop solar with open access?
Yes. Large users commonly cover part of the load from the roof and buy the rest as green power through captive or open access arrangements. Rooftop works best sized to what the unit consumes during the day, since exports earn far less than the tariff.
