Solar Panel Installation in Perungalathur
Realistic timelines for outer circles, with every application filed in parallel
Installations in Perungalathur are technically straightforward. What takes longer here than in central Chennai is the approval process, and the honest answer is to plan for it rather than promise a metro timeline you will not get.
Installing across Chennai since 2020
Two years free maintenance included
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 Perungalathur?
Perungalathur is mostly independent houses with their own terraces, which is the simplest case for rooftop solar: one owner, one roof, one connection. Because it sits low, we mount inverters, ACDB and earthing points above the levels the area has seen rather than at convenient waist height. We have installed across Chennai since 2020, file the PM Surya Ghar subsidy of up to ₹78,000 for households and the TANGEDCO net metering application ourselves, and include two years of free maintenance. 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 Perungalathur.

The local picture
Why approvals take longer out here
Net metering approval and meter installation in outer TANGEDCO circles generally take longer than in central Chennai. Section offices cover larger geographic areas with more dispersed sites, inspection visits require more travel, and meter installation is scheduled accordingly. The technical work is no harder; the elapsed time is longer, and any installer promising urban timelines here is either inexperienced or optimistic.
How we plan around it
Everything filed in parallel, never sequentially
The subsidy application, the net metering application, any sanctioned load enhancement and any three-phase conversion all go in together. Filed sequentially in an outer circle, a project can stretch to four months.
The connection checked at survey
So enhancements are identified before filing rather than after a rejection.
Realistic timelines quoted upfront
We would rather tell you eight to twelve weeks and deliver it than tell you six and miss.
Follow-up at the section office rather than waiting
TNERC regulations require a complete net metering application to be processed within a defined period, and where that is exceeded there is a formal escalation route through the consumer grievance channel.
Worth knowing about
Most consumers do not know they have an escalation route
They simply wait. We follow and escalate where the regulatory period is exceeded, which is precisely the part of the job an outer-circle customer benefits from most. The installation itself is easy here: plots are larger, terraces are generally clear, access is straightforward and structures are mostly recent enough to take an array without preliminary work.

Local guide
Solar for Perungalathur homes: lakes, commuters and the GST Road
Perungalathur takes its name from a big pond, and it still sits between two lakes: the 55 acre Perungalathur Lake and Peerkankaranai Lake beside the GST Road. That water, and the 10,000 plus people who commute from its railway station every day, shape how a system here should be designed.
Two lakes, two floods, and where the inverter goes
Peerkankaranai Lake was partly filled in when the GST Road was widened, and the low streets around both lakes have flooded more than once. Perungalathur is listed among the suburbs inundated by 5 December 2015. After Cyclone Michaung in December 2023, DT Next reported houses in Rajapah Nagar, Peerkankaranai flooded completely, with water up to 3 feet at the Vandalur to Minjur Outer Ring Road toll plaza. For a solar system the panels are never the problem. The inverter, distribution boxes, battery if you add one, and any cable joint are. We place them on the terrace or an upper floor wall, so that nothing but the net meter itself sits at ground level.
Out at work all day? Net metering still credits your units
Perungalathur railway station handles over 10,000 commuters a day on 84 suburban trains, so many households are out from morning to evening, which is exactly when panels generate. That does not make solar a poor fit. Homes keep net metering up to their sanctioned load, so units exported in the day are set off against units drawn at night. Size the system to your annual consumption, not to what the house uses at noon. The part of the bill that remains is the network charge on generation, about ₹0.32 a unit for homes up to 10 kW.
A sizing example at the Chengalpattu yield
The state rooftop calculator gives Chengalpattu district about 1,580 units per kW a year. A 3 kW system makes about 4,740 units a year and a 5 kW system about 7,900. Single-phase supply is limited to 4 kW, so a 5 kW system on a layout plot here also means converting to three-phase. A 5 kW system costs about ₹3,20,000 before subsidy and about ₹2,20,000 after the central and Tamil Nadu subsidies, for an eligible home. At about ₹0.32 a unit, the network charge on 7,900 units comes to roughly ₹2,500 a year, which is most of what remains on the bill.
Shops and lodges on the GST Road corridor
The Kalaignar Centenary Bus Terminus at Kilambakkam opened on 30 December 2023 on 88.52 acres along the same GST Road corridor, past Vandalur, to take long distance buses away from Koyambedu. Shops, eateries and lodges along the road are on non-domestic connections, which use net feed-in rather than net metering. Exported units are credited at ₹3.61 a unit up to 10 kW and ₹3.37 from 11 to 150 kW, well below what you pay for imports. So size a commercial system to the daytime load you actually run, not to the roof.

The process
How installation works
Free site survey
Shade-free roof area measured across the day, structure checked, connection name and sanctioned load confirmed.
Design and itemised quotation
Sized against twelve months of consumption, with every component named.
Approvals filed
PM Surya Ghar and TANGEDCO net metering, plus load enhancement or phase conversion in parallel where needed.
Installation
One to three days for a residential system, carried out by our own team rather than subcontracted.
Inspection and commissioning
TANGEDCO inspects, the net meter goes in, the system goes live.
Subsidy tracked to your account
And two years of maintenance included from commissioning.
We check the name on your electricity connection at the survey, because a mismatch stops more applications than any technical issue. See what to keep ready.
Free, no obligation
What will it cost on your roof in Perungalathur?
Been promised a six week timeline?
Out here that is optimistic. We quote eight to twelve, file everything in parallel, and escalate at the section office when the regulatory period is exceeded.
What happens after you send your details
- We call you within one working day, and an engineer rather than a salesperson attends the site.
- The survey is free. We measure usable area and shading, check your connection and sanctioned load, and photograph the site.
- You get an itemised quotation naming every component and brand, with the subsidy or depreciation position set out.
- No obligation at any point. If solar does not make sense for your property, we will say so.
Common questions
Solar in Perungalathur, common questions
Why do solar approvals take longer in Perungalathur?
Because outer TANGEDCO circles cover larger geographic areas with more dispersed sites, so inspection visits require more travel and meter installation is scheduled accordingly. The technical work is no harder; the elapsed time is longer. An installer promising central-Chennai timelines here is either inexperienced or optimistic.
How do you shorten the timeline?
By filing everything in parallel rather than sequentially. The subsidy application, the net metering application, any sanctioned load enhancement and any three-phase conversion all go in together, and the connection is checked at the survey so enhancements are identified before filing rather than after a rejection.
What if TANGEDCO exceeds the regulatory period?
There is a formal escalation route through the consumer grievance channel, and most consumers are unaware of it and simply wait. TNERC regulations require a complete net metering application to be processed within a defined period, and we follow and escalate where that is exceeded.
How long does installation take in Perungalathur?
Six to ten weeks from survey to a live system in Perungalathur. We avoid scheduling roof work through the heaviest monsoon weeks, so if you are starting in October or November expect the site dates to move rather than the approval.
Do you handle the subsidy and TANGEDCO paperwork?
Yes, we handle both and track the subsidy to your bank account. In Perungalathur we also photograph the inverter and protection positions at commissioning, because siting equipment above previous flood levels is worth documenting for both the warranty and any future insurance question.
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.
My street in Perungalathur flooded in 2023. Does that matter if the panels are on the roof?
The panels are safe up there, but the inverter, distribution boxes and cable joints are not if they are mounted low. We site all of them on the terrace or an upper floor. Also note that an on-grid system shuts down whenever supply is cut to a flooded area, so if you want power during such cuts you need a hybrid system with a battery kept upstairs.
Can I install more than 10 kW on a large house in Perungalathur?
You can, but the rules change above 10 kW. A home above that size loses the PM Surya Ghar subsidy, needs CEIG approval and needs a separate generation meter. For most houses here a system up to 10 kW, matched to the bill, gives the better return.
