Solar Panel Installation in Thirumazhisai

Skylights and purlins surveyed, so the quote reflects the roof you actually have

Industrial and warehouse roofs here are almost all profiled sheet, and most of them carry translucent skylight panels. Those skylights cannot be built over, and where they sit determines how much of the roof is genuinely available.

The local picture

Skylights, and the roof you actually have

Most industrial and warehouse buildings use profiled sheet roofing with translucent skylight panels set into it at intervals to provide daylight inside. Those panels cannot carry a solar array and cannot be covered, since covering them defeats their purpose and darkens the working space below. On a roof with regularly spaced skylights, the genuinely usable area for solar can be substantially less than the roof plan suggests.

What the roof survey establishes

Skylight positions and spacing

And how much contiguous sheet area remains between them.

Whether the array can span skylights

On a raised structure without shading them. Sometimes it can, provided the daylight below remains adequate, and sometimes the shading defeats the purpose.

Purlin positions and spacing

Which determine where the mounting can actually fix. Fixings go into structure, not into sheeting.

Sheet condition and remaining life

Which decides whether the roof is dealt with before or after the array, along with roof slope and orientation, since a sheet roof array follows the roof plane.

The daylight trade-off is worth taking seriously

Skylights reduce daytime lighting load, which is itself a saving

Covering them to gain array area can increase artificial lighting consumption, partly offsetting what the extra panels generate. On a building with substantial daytime occupancy that is a real calculation rather than a theoretical one.

The commercial rules apply as everywhere

Size to daytime self-consumption

Non-domestic consumers are generally on net feed-in rather than one-for-one net metering, so exported units earn well below what the unit pays on imports. Solar reduces the energy charge, not the demand charge, which is levied on contract or recorded maximum demand.

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.

Quoted from a roof plan?

On a sheet roof with skylights the usable area is well under the plan area. We survey the roof before pricing anything.

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 Thirumazhisai, common questions

Usually yes, and sometimes substantially. Translucent skylight panels cannot carry an array and covering them darkens the space below. On a roof with regularly spaced skylights the genuinely usable contiguous area can be well under what the roof plan suggests, which is why the survey measures rather than estimates.

Sometimes, on a raised structure that spans them without fully shading them, provided daylight below remains adequate. But skylights reduce daytime lighting load, which is itself a saving, so covering them can increase artificial lighting consumption and partly offset what the extra panels generate. It is a real calculation on an occupied building.

Into the purlins, which are the structural members beneath the sheeting, not into the sheets themselves. Purlin spacing and section therefore determine where fixings can go and how the array is laid out, alongside the skylight positions. That is established at the roof survey.

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.
