Solar Panel Installation in Alwarpet
Shading measured across the full day, because a tall neighbour changes everything by afternoon
Alwarpet has gone vertical faster than most of central Chennai. Multi-storey apartment blocks now sit alongside the older bungalows they replaced, and that creates a shading pattern that will not show up in any assessment done from the ground or from a satellite image.

The local picture
Tall neighbours and the shadow they cast
Alwarpet’s redevelopment has produced a mix of low-rise bungalows and multi-storey apartment buildings on the same streets, and a tall building beside a low one casts a long moving shadow across it for a significant part of the day. For a rooftop system on the lower property, that shading is the dominant design constraint, and it is entirely invisible in a satellite image or a ground-level visit.
What we do about it
Shading measured across the full day
Not at the moment of the visit. A building to the west will shade a roof through the afternoon and appear entirely benign at 10am.
Height as a partial solution
Raising the array can lift it clear of a neighbouring parapet or a two-storey block. It cannot clear a six-storey tower, and where that is the situation we say so rather than installing something that underperforms.
Split arrays with multiple MPPT inputs
So a section shaded through the afternoon does not drag the rest of the system down with it.
Honest sizing
On a heavily overshadowed plot the realistic system is smaller than the household consumption would justify, and a smaller system that performs is better than a larger one that does not.
For the tall buildings themselves
The position reverses entirely
Luxury apartment blocks here have unobstructed terraces above everything around them, sound structural capacity and associations with the means to act. Common-area systems covering lifts, pumps, STP, corridor and compound lighting claim ₹18,000 per kW, which at 15 or 20 kW is considerably more than the ₹78,000 an individual household is capped at.
Two more factors
Mature trees, and the bungalows that remain
Tree cover on the older streets adds a second shading factor on the lower properties, which compounds the first. Large surviving bungalows are among the better residential sites in central Chennai where they are not overshadowed: generous terraces, room for elevated structures, and high consumption from air conditioning and often an EV.

Residential
Solar for Alwarpet homes
Large independent houses and bungalows
Typically install 5 kW to 10 kW where shading permits, with elevated structures suiting the bigger terraces.
Luxury apartment blocks
The stronger opportunity, through common-area systems at ₹18,000 per kW.
Lower properties beside taller neighbours
Need shading measured across the day before any size is quoted.
Systems above 4 kW need three-phase supply
Which is common at these house sizes.
Commercial and industrial
Solar for Alwarpet businesses
Alwarpet’s commercial base is high-value and small-footprint.
Boutiques, galleries and showrooms
Evening-weighted, usually leased, and frequently in buildings where the terrace belongs to the owner rather than the occupant.
Restaurants and cafés
Refrigeration and daytime cooling suit solar; evening service does not.
Clinics and consulting practices
Good daytime match and commercial tariffs.
Offices in converted properties
Where structural condition and roof rights both need establishing before design.

The process
How installation works
Free site survey
Shade-free roof area measured across the day, structure checked, connection name and sanctioned load confirmed.
Design and itemised quotation
Sized against twelve months of consumption, with every component named.
Approvals filed
PM Surya Ghar and TANGEDCO net metering, plus load enhancement or phase conversion in parallel where needed.
Installation
One to three days for a residential system, carried out by our own team rather than subcontracted.
Inspection and commissioning
TANGEDCO inspects, both meters go in, the system goes live.
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

Tall building next door?
It may still work, with a split array and honest sizing. Or it may not, and we would rather tell you at the survey than after you have paid for it.
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 Alwarpet, common questions
Often yes, with design changes and honest sizing. Raising the array can lift it clear of a two-storey neighbour, and splitting the array with multiple MPPT inputs stops a shaded section pulling down the rest. Height will not clear a six-storey tower, and where that is the situation we say so rather than installing something that underperforms.
Because a building to the west shades a roof through the afternoon and looks entirely harmless at ten in the morning. In Alwarpet, where tall blocks sit beside low properties, a single-visit assessment will produce a system that generates well below what it was sold on.
Usually one of the better ones. Terraces on taller blocks sit above surrounding obstructions, structural capacity is generally sound, and the association route claims ₹18,000 per kW on common areas, which at 15 or 20 kW is considerably more than the ₹78,000 an individual household can claim.
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.
