Solar Panel Installation in Nanganallur
Elevated structures up to 9 feet that keep your terrace usable and clear the neighbours
Nanganallur is independent houses almost end to end, and the terraces here get used. Drying, storage, functions, sometimes a garden. That is exactly why elevated mounting matters more in this locality than in most, and why we quote it as an option rather than an afterthought.

Free site survey and energy audit, no obligation
The short answer
Looking for a solar panel installation company in Nanganallur?
Most of what we install in Nanganallur goes on independent houses, where the terrace belongs to the same person as the electricity connection and nothing needs a committee. Proximity to the airport means structure height here is worth checking at survey rather than at inspection. Installing across Chennai since 2020, we file the PM Surya Ghar application worth up to ₹78,000 for households, handle TANGEDCO net metering end to end, and cover two years of maintenance after commissioning. 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 Nanganallur.

The local picture
Why elevated structures suit Nanganallur
Nanganallur has one of the highest independent house densities in south Chennai, with plots close together and terraces that households actively use. Raising the array on an elevated structure up to 9 feet addresses both facts at once: the space underneath stays walkable and becomes shaded, and the panels clear the parapet and neighbouring shadow lines that constrain a low-mounted array on a tightly packed plot.
What raising the array does here
Keeps the terrace usable
Drying, storage and terrace access continue underneath, and the space becomes shaded rather than exposed, which in Chennai makes it more usable than before rather than less.
Clears neighbouring shadow
On close-packed plots a neighbouring parapet or a low adjacent roof shades a low-mounted array for part of the day. Height often lifts the panels above that line entirely.
Spans obstructions
Water tanks and staircase headrooms can be built over rather than worked around, which frequently allows a larger system on the same roof.
Improves generation
Airflow beneath the panels keeps them cooler, and every panel loses output as it heats. In Chennai’s climate that difference is real rather than theoretical.
The honest cost position
An elevated structure costs meaningfully more
It uses more steel, deeper foundations and heavier anchoring than a low mount. We state the difference before you decide rather than folding it into a single figure. Whether it is worth it depends on how much you actually use your terrace and how obstructed your roof is.
Wind design matters at height
Designed to the requirement, not built to a template
Chennai sits in a 50 m/s basic wind speed zone under IS 875 Part 3, and raising an array increases both wind load and the overturning force at the base. It is a fair question to put to any installer quoting you a raised structure. On very tight plots we also check that raising your array does not create a shading problem for a neighbour, because that is easier to design around than to resolve afterwards.

Local guide
Rooftop solar in Nanganallur: airport heights and 1980s terraces
Nanganallur grew rapidly from the mid-1980s and joined Chennai Corporation in September 2011, so much of its housing dates from those decades. It also sits beside Chennai International Airport, where structure height is regulated.
What checking height near the airport actually means
The Airports Authority of India publishes a colour coded zoning map that gives each grid square around the airport a permitted top elevation in metres above mean sea level. Your headroom is that figure minus your plot's ground level. A building below it can be approved by the local body without AAI. A site in a red grid, or a design that goes above the figure, needs an AAI no objection certificate through its NOCAS portal. AAI does enforce this: in February 2025 it asked owners in Kolapakkam to lower structures by about two metres to clear the secondary runway. An elevated structure of up to 9 feet adds more than that.
Terraces built in the 1980s and 1990s need checking first
A solar array stays on your terrace for 25 years, and the anchors go into the slab. On houses built during Nanganallur's growth from the mid-1980s, we check three things before designing. First, the waterproofing: if it is due, redo it before installation, because lifting an array later costs labour and risks the anchors. Second, the slab itself, for cracks, exposed steel or damp patches. Third, the parapet, if the design anchors to it. Where the slab is doubtful, we spread the load with a wider base frame or keep the raised structure lower.
When the subways flood, plan for remote monitoring
Nanganallur reaches GST Road through the Palavanthangal and Thillai Ganga Nagar subways, and the Palavanthangal subway is known to flood in heavy rain. During Cyclone Michaung on 5 December 2023, police closed both the Pazhavanthangal and Thillai Nagar subways. If the area is cut off for a few days, a service visit has to wait. So we connect the inverter to your Wi-Fi with generation monitoring, and set alerts for zero output. Then a fault after a storm shows up on your phone, not on your next bill.
A sizing example for a Nanganallur house
Chennai district's yield is about 1,600 units per kW a year. A 3 kW system makes about 4,800 units a year and a 5 kW system about 8,000. Single-phase supply is limited to 4 kW, so a 5 kW system needs three-phase. A 5 kW system costs about ₹3,20,000 before subsidy and about ₹2,20,000 after the ₹78,000 central subsidy and the ₹22,000 Tamil Nadu top-up, for an eligible home. An elevated structure adds to that cost, and we show it as a separate line so you can compare the two mounting options.

What will it cost on your roof in Nanganallur?
Do not want to lose your terrace?
You do not have to. A raised structure leaves the space walkable and shaded underneath, and it usually clears the neighbouring shadow line as well.
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 Nanganallur, common questions
Can I still use my terrace after installing solar in Nanganallur?
Yes, with an elevated structure. Raising the array up to 9 feet leaves the space underneath walkable and shaded, so drying, storage and terrace access all continue. Most households find the terrace more usable afterwards than before, because the array blocks direct sun over the area it covers.
Does an elevated solar structure cost much more?
Yes, meaningfully. It uses more steel, deeper foundations and heavier anchoring than a low mount. We state the difference before you decide rather than folding it into one figure. Whether it is worth it depends on how much you use your terrace and how obstructed your roof is by tanks, headrooms and neighbouring buildings.
Is a raised structure safe in Chennai wind conditions?
It has to be designed for it. Chennai sits in a 50 m/s basic wind speed zone under IS 875 Part 3, and raising an array increases both wind load and the overturning force at the base, so heavier sections, deeper foundations and stronger anchoring are required. Ask what wind speed the structure is designed to and who verified it.
How long does installation take in Nanganallur?
Plan on six to ten weeks in Nanganallur. Height confirmation happens during design; the installation is one to three days and approval is the variable.
Do you handle the subsidy and TANGEDCO paperwork?
Yes, we file both. Alongside the PM Surya Ghar application and TANGEDCO net metering, we confirm structure height at survey in Nanganallur given the airport proximity, so nothing is queried at the inspection stage.
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.
My terrace was waterproofed years ago. Should I redo it before installing solar?
If it is more than about ten years old or shows damp patches below, yes. An array covers a large part of the terrace for 25 years, and redoing waterproofing underneath it later means dismantling part of the system. Do it in the dry months before installation.
Do I need an AAI NOC for an elevated solar structure in Nanganallur?
Only if the finished top of your building would exceed the permitted elevation for your grid on AAI's zoning map, or if your grid is marked red. We check the actual building height and grid at the survey rather than assume it.
