Solar Panel Installation in Nandanam

A monthly generation benchmark at handover, so you can check us rather than trust us

A commercial solar proposal always includes a generation figure. What it rarely includes is how you would know whether the system is actually delivering it. For an office or institution in Nandanam that is the question worth asking before signing.

The local picture

How will you know it is working?

Every solar proposal contains an expected generation figure, and almost none explains how the buyer will verify it after commissioning. For a commercial or institutional buyer spending a substantial sum, the verification arrangement matters as much as the specification, because without it an underperforming system can run for years before anyone notices.

What a commercial buyer should insist on

A stated monthly generation expectation

Not just an annual figure. Chennai’s output varies seasonally, peaking in the clear months and dipping through the northeast monsoon, so a single annual number gives you nothing to check against in March.

A generation meter, read independently of the app

Tamil Nadu requires a separate solar generation meter alongside the bi-directional net meter, and that meter is the authoritative record of what the array produced regardless of what you consumed.

Monitoring configured and explained at handover

With someone on your side who knows what normal looks like.

A defined response if generation falls short

What happens, who investigates, and within what period. A guarantee with no measurement method and no remedy is decoration.

Clarity on what is excluded

Soiling, shading from something new, and grid outages affect output and are not equipment faults. A fair arrangement says so explicitly rather than leaving it ambiguous.

Why underperformance goes unnoticed

Output declines gradually rather than failing suddenly

Nobody notices until generation is well down. A facilities team with a monthly benchmark spots it in weeks. A facilities team without one spots it in years, if at all. We set the benchmark at handover and include it in the documentation, because a number you can check us against is worth more than an assurance.

The familiar constraints still apply

Commercial and institutional stock

Roofs carrying plant with maintenance access to preserve, usable area well below gross, and for institutions a trust tax position where accelerated depreciation may be worth nothing.

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.

Been given an annual generation figure?

That is not checkable in March. Ask for monthly expectations and a generation meter reading, or you will never know.

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 Nandanam, common questions

By comparing actual generation against a stated monthly expectation, using the generation meter rather than only the app. Tamil Nadu requires a separate solar generation meter, and it is the authoritative record of what the array produced regardless of consumption. We set the monthly benchmark at handover and include it in the documentation.

Because output declines gradually with soiling rather than failing suddenly. A facilities team with a monthly benchmark notices within weeks. Without one, a system can run well below its capability for years before anyone questions it, and by then the lost generation is unrecoverable.

A measurement method, a defined period, a remedy if the figure is not met, and an explicit statement of what is excluded, such as soiling, new shading or grid outages. A guarantee without a measurement method and a remedy is decoration rather than protection.

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.
