Solar Panel Installation in Thousand Lights
Straight answer on what a tall building’s roof can and cannot do for its bill
On a tall commercial building the roof is small relative to what the building consumes, and the obvious thought is to put panels on the facade instead. It is a fair question, and the honest answer today is that it rarely stacks up in India.

The local picture
Tall buildings, small roofs, and the facade question
A tall building has the same roof area as a low one on the same footprint, but many times the floor area and therefore many times the consumption. On the multi-storey commercial buildings along the Thousand Lights and Anna Salai stretch, rooftop solar can only ever offset a modest share of the load, which leads owners to ask about building-integrated or facade-mounted solar.
The honest position on facade solar
It is technically possible
And is being done on some buildings internationally.
Vertical panels generate substantially less
Than roof-mounted ones at this latitude, because sunlight strikes them at a poor angle for most of the day. The closer to the equator, the worse vertical performs.
Cost per unit generated is considerably higher
Since building-integrated products and their installation cost more than standard modules on a roof.
In the Indian market today it is rarely economic
On a straightforward payback basis, and we would rather say so than sell it. Where it does get chosen, the driver is usually architectural or reputational rather than financial, and that is a legitimate reason provided the buyer knows that is what they are paying for.
What actually works on a tall building here
Use the roof properly
After accounting for chillers, air handling units, condenser banks, telecom equipment and access, the usable area is what it is, and a well-designed array on it still displaces a useful share of daytime energy charges.
Understand what it can and cannot do
It reduces the energy charge, not the demand charge, and non-domestic consumers are generally on net feed-in rather than net metering.
Look at consumption before generation
On a large commercial building, efficiency measures frequently return more per rupee than adding generation, and an audit will show whether that is your position.
Along this stretch
Hotels have continuous load with evening and overnight peaks
So solar covers the daytime portion including laundry, kitchen and daytime cooling rather than the whole bill.

Considering facade solar?
At this latitude vertical panels generate poorly and cost more per unit. We would rather tell you that than sell it to you.
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 Thousand Lights, common questions
Technically yes, but it rarely stacks up financially in India today. Vertical panels generate substantially less than roof-mounted ones at this latitude because sunlight strikes them at a poor angle, and building-integrated products cost considerably more per unit generated. Where it is chosen the driver is usually architectural rather than financial.
A modest share of the load, because a tall building has the same roof area as a low one but many times the consumption. After chillers, air handling units, telecom equipment and access are accounted for, the usable area is limited. It still displaces a useful amount of daytime energy charges, but it will not transform the bill.
Consumption before generation. On a large building, efficiency measures frequently return more per rupee than adding generation, and an energy audit will show whether that is your position. We would rather tell you that than size a system that cannot address the problem.
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.
