Solar Panel Installation in Kolathur

We work out which connection the system should serve before designing anything

Kolathur has a very high proportion of independent houses, and a great many of them were built with rental income in mind. That produces something worth settling before anything is designed: a single building with several separate electricity connections, only one of which a solar system can serve.

The local picture

One roof, several electricity connections

A large share of Kolathur’s independent houses include portions built or adapted for letting, and where that has happened the building frequently carries more than one TANGEDCO service connection. This matters because a rooftop solar system connects to one specific service connection, and it reduces the bill on that connection only. Whose consumption is offset, and whose name the subsidy is claimed in, follow directly from that choice.

The questions to settle before design

How many service connections does the building have?

Owner’s portion and let portions frequently have separate meters.

Which connection will the system serve?

Usually the owner’s, but not always, and it should be a deliberate decision.

Whose name is each connection in?

The subsidy application and net metering application are both tied to the service connection and require the applicant’s name to match. If a connection is in a tenant’s name, that route is not open to the owner.

Does the sanctioned load on that connection support the system?

Individual connections in a subdivided building often have modest sanctioned loads, which caps the system size regardless of roof area.

The practical consequence

A large roof can still only support a modest system

The system is limited by the sanctioned load of the single connection it serves rather than by the roof or by the building’s total consumption. This surprises owners regularly, and it is far better established at the survey than at the feasibility stage.

Otherwise, a straightforward locality

Sound slabs, reasonable plots and terraces that get used

Where the owner holds a connection with adequate sanctioned load, Kolathur works well: independent houses, generally sound slabs, and terraces that suit elevated structures. Vertical extension is common, with houses built up floor by floor over the years, so array loading is assessed against the whole structure rather than the newest slab.

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.

Free, no obligation

Several meters in your building?

Then the system serves one of them, and which one decides whose bill drops and whose name the subsidy is in. Worth deciding rather than defaulting.

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 Kolathur, common questions

The system connects to one specific service connection and reduces the bill on that connection only. Which one it serves should be a deliberate decision rather than an assumption, because it determines whose consumption is offset and in whose name the subsidy is claimed. We establish this at the survey.

Not on that connection, as the owner. Both the subsidy application and the net metering application are tied to the service connection and require the applicant’s name to match. If the owner holds a separate connection with adequate sanctioned load, that is the route. Otherwise the connection position needs resolving first.

Because the system is capped by the sanctioned load of the single connection it serves, not by roof area or by the building’s total consumption across all connections. In a subdivided building with several modest connections, that limit often binds well before the roof does.

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.
