Solar Panel Installation in Navalur
Plan it in before construction finishes and it costs considerably less than retrofitting
Navalur is still being built, and that creates an opportunity most parts of Chennai no longer have. Decisions about lighting, common-area power and EV charging can be made before the infrastructure goes in rather than retrofitted afterwards, and doing it in that order costs considerably less.

The short answer
Looking for a solar panel installation company in Navalur?
Navalur mixes independent houses with apartment blocks, so the first question on any survey here is who owns the terrace and which meter the system will feed. Most buildings are recent, so structure is rarely the obstacle. Sanctioned load and the meter position usually are. 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 Navalur.

The local picture
Building it in rather than retrofitting it
Navalur’s growth is recent and ongoing, with new layouts, gated communities and apartment complexes still being developed. For solar that changes the sequence: a layout or community planned with solar street lighting and common-area generation in mind avoids the trenching, cabling and metering costs that retrofitting later incurs, and the association inherits a lower running cost from day one rather than voting on it years afterwards.
For developers and layout promoters
Solar street lighting instead of conventional
Each pole carries its own panel and battery, so there is no cabling back to a distribution board, no meter, no connection application and no ongoing electricity bill for the lighting. On a new layout, avoiding the trenching and cable cost alone is significant. See solar street lights.
Plan it before the roads go in
Not after. Retrofitting lighting into a completed layout means cutting into finished surfaces.
Common-area generation designed in
So the association takes over a building with lower running costs rather than a proposal to reduce them.
Minimum project size is 50 units
For lighting, which most layouts of any scale exceed comfortably.
For gated communities and associations
Newer buildings
Generally have sound structural capacity, clear terraces and adequate sanctioned load, which makes installation straightforward.
Common-area systems
Claim ₹18,000 per kW up to 500 kW, covering lifts, pumps, STP, corridor and compound lighting and EV charging points.
Associations formed recently
Tend to decide faster than established ones, though a general body resolution is still required and remains the longest step.
EV charging
Should be planned alongside solar rather than as a separate later project, since the subsidy provision covers both.
For individual villa owners
Inside a gated community, the normal residential route applies
Individual roofs with individual connections follow the standard household path, though architectural control rules often apply and should be checked before committing to a design.

Local guide
Navalur rooftop solar: catchment, district rules and villa sizing
Navalur is on OMR about 5 km south of the Sholinganallur junction, but it falls in Thiruporur taluk of Chengalpattu district, outside the Greater Chennai Corporation, which matters more for paperwork than for engineering.
Rain in Navalur ends up in the Pallikaranai marsh
The Pallikaranai marsh has a catchment of about 235 square kilometres that includes Navalur. The marsh has lost most of its original area to building and has been cut in two by a road with no free flow beneath, so it absorbs less than it once did. When it is full, water from the catchment has nowhere fast to go. In December 2023, neighbourhoods along OMR such as Perumbakkam, Semmencheri and Pallikaranai stayed under water for days. On a new Navalur layout, check how high the plinth sits above the road before deciding where equipment goes. If it is low, put the inverter and distribution board in the terrace stair room or on an upper-floor wall, not in the car porch.
Metro works and dust along OMR
Chennai Metro's Phase 2 corridor runs along OMR towards Siruseri. Where civil works are active in front of a building, concrete and road dust settle on rooftops far faster than usual. If your terrace faces an active work zone, plan monthly cleaning for that period rather than the usual interval, and check the inverter app for a steady slide in daily units, which is the sign that dust, not weather, is cutting output. Once works move on, return to the normal routine. Buildings set back inside the layouts, away from the main road, see much less of it. Rinse with plain water first, since dry-brushing cement dust scratches the glass.
Sizing a villa on a Navalur layout
The state rooftop calculator uses 1,580 units per kW a year for Chengalpattu district, about 4.3 units a day. A 3 kW system, the smallest we install, makes about 4,740 units a year. A 5 kW villa system makes about 7,900 units a year, roughly 1,320 per two-month billing cycle. It costs about ₹3,20,000 before subsidy and about ₹2,20,000 after the central ₹78,000 and the ₹22,000 Tamil Nadu top-up. Single-phase supply stops at 4 kW, so a 5 kW villa needs three-phase. Homes keep net metering up to their sanctioned load and pay no fixed charge, so the remaining bill is mostly the network charge of about ₹0.32 a unit. For flats, the association's common-area route at ₹18,000 per kW usually beats individual systems.
What we install
What we install in Navalur
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, 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 Navalur?
Waiting until the layout is finished?
That is the expensive order. Solar street lighting needs no trenching or cabling, so planning it in before the roads go down avoids a cost you cannot recover later.
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 Navalur, common questions
Should a new Navalur layout use solar street lighting?
It is worth costing properly, because the comparison is not just lighting against lighting. Solar street lights need no cabling back to a distribution board, no meter, no connection application and no ongoing electricity bill, so on a new layout you avoid trenching and cable cost as well. That saving rises with distance from the nearest supply point. Projects start from 50 units.
When should a developer plan solar into a project?
Before the roads and common areas are finished. Retrofitting lighting into a completed layout means cutting into finished surfaces, and retrofitting common-area generation means working around an occupied building. Planning it in means the association inherits lower running costs rather than being asked to vote on reducing them later.
How much subsidy can a Navalur gated community claim?
₹18,000 per kW for common-area facilities, up to 500 kW and subject to 3 kW per residential unit, covering lifts, pumps, the STP, corridor and compound lighting and EV charging points. At 20 kW that is ₹3,60,000, considerably more per kW than the ₹78,000 an individual household is capped at.
How long does installation take in Navalur?
Six to eight weeks from survey to a live, net-metered system is typical in Navalur, and newer areas often land at the shorter end because connection records are current. The installation itself is one to three days for a home; the rest is TANGEDCO approval and the meter.
Do you handle the subsidy and TANGEDCO paperwork?
Yes, both are ours to file. Applications from newer areas like Navalur usually move faster because the connection details and sanctioned load are recent and correct. We still verify the name on the connection and the load at the survey, then track the subsidy to your bank account after commissioning.
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.
Navalur is outside Chennai Corporation. Does that change the solar subsidy?
No. The subsidy and net metering depend on your domestic electricity connection, not the civic body. Eligible homes get up to ₹78,000 from PM Surya Ghar plus the ₹22,000 Tamil Nadu top-up, applied for through the national portal and the electricity distributor, as in Chennai.
Our layout off OMR sits low. Where should the inverter go?
Up high. Navalur drains towards the Pallikaranai marsh, and when the marsh is full, water backs up across the catchment. Put the inverter and distribution board in the terrace stair room or on an upper-floor wall, and bring cables down the outside wall in conduit.
