Solar Panel Installation in Thoraipakkam

Sized to when you actually consume, which matters more here than how much roof you have

Thoraipakkam has an unusually mixed frontage even by OMR standards. Apartment blocks, offices and a growing showroom strip all sit within a few hundred metres of each other, and each consumes electricity in a completely different pattern. The right system size depends far more on which of the three you are than on how much roof you have.

The local picture

Three load patterns on one road

Thoraipakkam mixes apartment complexes, IT and commercial offices, and a showroom and retail strip along the OMR frontage. These three consume in fundamentally different patterns, and since solar generates for roughly five effective hours around midday, the pattern determines how much of a bill it can actually displace.

Property typeWhen the load peaksWhat solar covers
Apartment common areasLifts and pumps by day, lighting by nightStrong. Most daytime load is offset
OfficesWorking hours, 9 to 6Excellent. Close to an ideal match
Showrooms and retailLate afternoon into the eveningPartial. Daytime cooling and lighting only

What that means for sizing

Sizing follows the load, not the roof

A showroom with a large roof and evening-weighted trading will offset a smaller share of its bill than an office with half the 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.

For apartment associations

The common-area route claims ₹18,000 per kW rather than the ₹78,000 household cap, and covers lifts, pumps, the STP, corridor and compound lighting and EV charging points. That last inclusion is worth knowing before a committee treats solar and EV charging as separate projects.

For retail on leased frontage

Roof rights are the first question, ahead of roof size. Many showrooms occupy buildings with other occupants above and have no control over the terrace. Where parking is within your demise, a solar carport generates power and shades customer vehicles.

Residential

Solar for Thoraipakkam homes

Apartment associations

The main residential opportunity, with common-area systems the practical route since individual flat owners cannot install on a shared terrace.

Independent houses

In the pockets away from the main road, typically installing 3 kW to 5 kW.

Newer buildings

Generally have sound structural capacity and adequate sanctioned load, which shortens the timeline.

Commercial and industrial

Solar for Thoraipakkam businesses

Offices

The strongest commercial case here, with consumption matching generation almost exactly and commercial tariffs making each displaced unit worth more.

Showrooms and retail

Evening-weighted, so expect a meaningful reduction rather than elimination, and establish roof rights before designing anything.

Restaurants and food service

Refrigeration and cooling through the day, evening trading a large share.

Clinics and diagnostic centres

Daytime load, with equipment that makes power quality a legitimate design question.

The process

How installation works

1

Free site survey

Shade-free roof area measured across the day, structure checked, connection name and sanctioned load confirmed.

2

Design and itemised quotation

Sized against twelve months of consumption, with every component named.

3

Approvals filed

PM Surya Ghar and TANGEDCO net metering, plus load enhancement or phase conversion in parallel where needed.

4

Installation

One to three days for a residential system, carried out by our own team rather than subcontracted.

5

Inspection and commissioning

TANGEDCO inspects, both meters go in, the system goes live.

6

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.

Comparing quotes on system size alone?

On this road that is the wrong comparison. A showroom and an office with the same roof offset very different shares of their bill, because of when they use power.

What happens after you send your details

  1. We call you within one working day, and an engineer rather than a salesperson attends the site.
  2. The survey is free. We measure usable area and shading, check your connection and sanctioned load, and photograph the site.
  3. You get an itemised quotation naming every component and brand, with the subsidy or depreciation position set out.
  4. No obligation at any point. If solar does not make sense for your property, we will say so.

Common questions

Solar in Thoraipakkam, common questions

Because of when you consume, not how much roof you have. Showroom trading extends well past sunset, and display lighting and air conditioning peak in the evening, while solar generates for roughly five effective hours around midday. An office consuming 9 to 6 matches generation almost exactly. The same roof produces the same units; what differs is how many of them you use yourself.

Yes. The PM Surya Ghar common-area provision explicitly covers EV charging infrastructure alongside lifts, pumps and lighting, at ₹18,000 per kW up to 500 kW. It is worth knowing before a committee treats solar and EV charging as two separate projects with separate approvals.

Only with the property owner’s written agreement, and often the roof is not available at all where the building has other occupants above. Where parking or forecourt is within your demise, a solar carport is an alternative that does not depend on roof rights, and it shades customer vehicles, which is a benefit in its own right.

Six to ten weeks from survey to a live, net-metered system, with TANGEDCO approval and meter installation the main variable. The installation itself is one to three days for a residential system, and longer for a commercial or industrial project.

Yes. We file the PM Surya Ghar application and the TANGEDCO net metering application, follow both through the section office, and track the subsidy to your bank account. We also check the name on your electricity connection at the survey, since a mismatch stops applications more often than any technical issue.

Two years of free maintenance from commissioning, covering panel cleaning, annual inspection of connections and structure, generation monitoring and warranty coordination with the manufacturer.
