Solar Panel Installation in Purasawalkam
Shop or home connection modelled side by side, because the subsidy sits on one and the higher tariff on the other
Purasawalkam is old Chennai retail with residences stacked above it. A shop at street level, a family upstairs, sometimes a tenant on the floor between. For solar that mixed-use pattern raises two questions at once: who controls the roof, and which tariff the system is actually offsetting.

The short answer
Looking for a solar panel installation company in Purasawalkam?
Purasawalkam is tightly packed, and on most terraces here the limit is usable shade-free area, not budget. Many buildings here are older, and existing wiring and earthing often need attention before a system can be connected safely. Blues Renewables has worked across Chennai since 2020. We handle the PM Surya Ghar claim of up to ₹78,000 where the property is residential, file the TANGEDCO net metering paperwork, and include two years of maintenance. Before the survey, you can check the solar panel price in Chennai for 3 kW to 10 kW systems and see how our solar panel installation in Chennai works, the same process we follow in Purasawalkam.

The local picture
Mixed use buildings and two questions at once
Purasawalkam’s characteristic building is mixed use: commercial at street level with residential above, frequently in the same family’s ownership and frequently with separate electricity connections for each. That creates two questions that have to be answered together, because the answers interact. Who has documented rights to the terrace, and which service connection, on which tariff category, will the system serve.
Why the tariff category question matters as much as the roof
A domestic connection
Qualifies for the PM Surya Ghar subsidy of up to ₹78,000, and for one-for-one net metering.
A commercial connection
Receives no subsidy, but the business can claim accelerated depreciation of up to 40% in the first year plus GST input credit, and it is generally on net feed-in rather than net metering.
The connection the system serves determines which regime applies
So in a mixed-use building this is a genuine decision rather than a formality.
The commercial tariff is higher
So a unit displaced on the shop connection saves more than a unit displaced on the residential one, though the subsidy sits on the other side. Which is better depends on your consumption split and your tax position, and we set out both at the survey.
Often the harder question
Who has rights to the terrace
Where a building has been divided between family members or partially let, the terrace may be shared, undivided or held by one party while another holds the connection. Written consent from co-owners is generally needed, and obtaining it before design is far easier than afterwards.
Physically
Dense old stock, and realistic sizing
Narrow plots, buildings close together, usable shade-free area well below terrace measurement, and narrow lanes affecting material access. Realistic sizing here is typically 3 kW. Retail load is evening-weighted, so a system on the shop connection covers daytime cooling and lighting rather than the trading peak.

Local guide
Purasawalkam rooftops: ridge, nullah and the metro below
Purasawalkam High Road follows a natural ridge, with the Otteri channel in the lower ground to its west. Which side of that ridge your building stands on tells you a lot about its flood risk.
Ridge side or nullah side
The Otteri Nullah runs 10.2 km from Anna Nagar through Kilpauk, Kellys and Purasawalkam to the Buckingham Canal at Basin Bridge. Citizen Matters reported that homes along its stretch flood most years, with water mixed with sewage entering houses, because encroachments and debris have narrowed it. Buildings on the High Road ridge sit higher than those towards the channel. For properties on the lower side, we keep the inverter and the solar distribution box on the terrace or an upper floor, raise any ground-floor junction box above the known water line, and seal cable entries from below. On the ridge, the usual wall-mounted layout near the meter is normally fine. The News Minute also reported in 2024 that metro work had disrupted stormwater drain projects in Purasawalkam.
Working above a metro construction site
Chennai Metro Rail is building an underground station of more than 300 metres beneath Purasawalkam junction. CMRL told The Hindu that shifting utilities here was the hardest of the Phase II network, with close to 100 power cables and large water and sewer lines moved within a narrow road. DT Next reported 11 kV feeders and three transformers among the utilities diverted. For a rooftop job this means planning deliveries around traffic diversions on the High Road, carrying materials in during quieter hours, and checking an old terrace for cracks before drilling anchors. Where a slab is doubtful, a ballasted frame avoids new penetrations, and an engineer's note on the slab is worth having before any weight goes on it.
Two worked examples
On the Chennai yield of about 1,600 units per kW a year, roughly 4.4 a day, a 3 kW system on the residential connection makes about 4,800 units a year. For an eligible home that costs about ₹2,10,000 before subsidy and about ₹1,10,000 after both subsidies. The same 3 kW on a shop's commercial connection gets no subsidy, but each unit used in the day saves the commercial tariff, and any export is credited at ₹3.61 a unit under net feed-in. In a building with both connections, that comparison is worth doing on paper before choosing which meter the system feeds. Above 4 kW, the residential side would also need three-phase supply.

One to three days for a residential system, carried out by our own team rather than subcontracted.
Inspection and commissioning
TANGEDCO inspects, the net meter goes 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
What will it cost on your roof in Purasawalkam?
Shop below, home above, and unsure which to connect?
That is a real decision with real money on it. We model both rather than defaulting to whichever is convenient.
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 Purasawalkam, common questions
Our building has a shop below and a home above. Which connection should solar serve?
It depends on your consumption split and your tax position, and it is a genuine decision. A domestic connection qualifies for the PM Surya Ghar subsidy of up to ₹78,000 and one-for-one net metering. A commercial connection gets no subsidy but the business can claim accelerated depreciation and GST input credit, and commercial tariffs are higher so each displaced unit saves more. We set out both at the survey.
Our property is divided between family members. Can we install solar?
Yes, but the roof ownership needs settling first. A solar system requires documented rights to the terrace and is tied to a specific service connection, so where a property has been divided, the applicant, the connection and the roof rights all need to align. Written consent from co-owners is usually required.
Will solar cover my Purasawalkam shop’s bill?
Part of it. Retail trading here extends well into the evening, and display lighting and cooling peak after sunset, while solar generates for roughly five effective hours around midday. Daytime cooling and lighting load is worth displacing, but expect a meaningful reduction rather than elimination, particularly given the limited roof area on these plots.
How long does installation take in Purasawalkam?
Six to ten weeks from survey to a live system. In Purasawalkam the installation itself can take an extra day because material has to come up by staircase, but the timeline is still governed by TANGEDCO approval and the meter, not by the roof work.
Do you handle the subsidy and TANGEDCO paperwork?
Yes. We file the PM Surya Ghar claim and the TANGEDCO net metering application for you and follow both through the section office. In Purasawalkam the detail that delays applications most often is the sanctioned load being too low for the system you want, which we check before designing so the load enhancement runs in parallel rather than afterwards.
What is included after installation?
Two years of free maintenance from commissioning, covering panel cleaning, annual inspection of connections and structure, generation monitoring and warranty coordination with the manufacturer.
Our Purasawalkam building is on the Otteri Nullah side. Does that change the solar design?
Yes, mainly in where the equipment sits. We keep the inverter and distribution box on the terrace or an upper floor and seal cable entries, so a flooded street does not reach the electronics.
Will the metro works on Purasawalkam High Road delay our solar installation?
They affect logistics more than the timeline. Deliveries are planned around diversions, and the overall schedule is still set mostly by TNPDCL approval and the meter.
