Solar Panel Installation in Vandalur
Campus connections mapped before design, because scattered buildings mean several projects
Vandalur’s institutional sites are spread out rather than stacked up. Buildings scattered across large grounds, sometimes with separate electricity connections, which makes campus solar here a different design problem from a single large roof.

The short answer
Looking for a solar panel installation company in Vandalur?
Most of what we install in Vandalur goes on independent houses, where the terrace belongs to the same person as the electricity connection and nothing needs a committee. It has space, so the right answer here is sometimes a ground-mounted array rather than a rooftop one. 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 Vandalur.

The local picture
Campuses with scattered buildings
Institutional properties in Vandalur tend to occupy large grounds with multiple separate buildings rather than one consolidated block. That changes campus solar design considerably, because a system connects to a specific service connection and offsets consumption on that connection only. A campus with several connections across several buildings is several projects, not one.
What has to be established first
How many service connections the site has
And which buildings sit on each. On older institutional sites this is frequently undocumented and worth mapping properly.
Where the load actually is
Administrative buildings, workshops, hostels and pumping stations consume very differently, and the generation should sit where the consumption does.
Which roofs are usable
Scattered buildings mean varying roof types, ages and structural conditions across one site.
Whether ground-mount is available
Institutional sites with open grounds often have space for a ground-mounted array, which can be sized to a connection’s load without being constrained by a particular building’s roof.
Genuinely worth considering on these sites
Ground-mount
Tilt and orientation can be optimal rather than following a roof, maintenance and cleaning access is at ground level, and capacity is not limited by any single building. The trade is that it occupies land and costs more in foundations and civil work.
The tax position applies as with all institutions
Depreciation is worth nothing without taxable income
Where the entity is a trust or society, an OPEX structure often compares better than ownership. That should be checked with the institution’s auditor before evaluating any proposal.

Local guide
Solar in Vandalur: what the zoo, the terminus and your terrace have in common
Vandalur's best known institution, the Arignar Anna Zoological Park, already runs a 180 kW solar plant that meets about 80 per cent of its power needs, the Tamil Nadu government said in October 2025. The same daytime logic applies to the colleges, shops and homes around it.
What the zoo's 180 kW plant tells a Vandalur campus
The zoo covers 80 per cent of its electricity with 180 kW, and a share that high is only possible where most of the load runs in daylight and the site has room for the array. At the district yield that plant makes roughly 2,84,000 units a year. Any day-run campus on the GST Road can test itself the same way. Crescent Institute, for example, sits on a 50 acre campus between the bus terminus and the zoo. The share of the bill solar can cover depends on two numbers: how much of your consumption falls between 9 am and 4 pm, and how much shade-free roof or ground you have. Pull twelve months of meter readings before anyone quotes a percentage.
Shops and offices near the Kilambakkam terminus
The Kalaignar Centenary Bus Terminus opened on 30 December 2023 on 88.52 acres beside the GST Road, and was built with its own solar panels and rainwater harvesting. A shop, office or eatery on that stretch is on a non-domestic connection, which works on net feed-in rather than net metering. Every unit you use on site saves the full commercial tariff, while every unit exported is credited at ₹3.61 for systems up to 10 kW and ₹3.37 from 11 to 150 kW. So the design rule is to size the array to your steady daytime load, such as fridges, air conditioning and lights, not to the roof area, and to keep exports small.
Sizing a Vandalur home at the Chengalpattu yield
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 makes about 4,740 units a year; a 5 kW system about 7,900. A 3 kW system costs about ₹2,10,000 before subsidy and about ₹1,10,000 after the ₹78,000 central subsidy and the ₹22,000 Tamil Nadu top-up. A 5 kW system costs about ₹3,20,000, about ₹2,20,000 after both. Single-phase supply is limited to 4 kW, so a 5 kW home needs three-phase. After commissioning, what stays on the bill is mainly the network charge on generation, about ₹0.32 a unit. Homes keep net metering up to their sanctioned load, so units exported at midday are set against units used at night.

What we install in Vandalur
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 Vandalur?
Campus spread across several buildings?
Then it is several projects, not one. We map the connections and put the generation where the consumption actually is before designing anything.
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 Vandalur, common questions
How is solar designed for a scattered campus?
By mapping the service connections first. A system connects to one connection and offsets consumption on that connection only, so a campus with several connections across several buildings is several projects. On older institutional sites the connection map is frequently undocumented and worth establishing properly before design.
Is ground-mount worth considering on an institutional site?
Often, where there is open ground. Tilt and orientation can be optimal rather than following a roof, cleaning and maintenance access is at ground level, and capacity is not limited by any single building’s roof. The trade is that it occupies land and costs more in foundations and civil work.
Can a trust-run institution claim accelerated depreciation?
Only with taxable income to offset. Most operate as trusts or societies, so depreciation is worth nothing to them and an OPEX or RESCO structure often compares better than ownership. Check with the institution’s auditor before evaluating any proposal.
How long does installation take in Vandalur?
Six to ten weeks, though section offices covering Vandalur can run longer than the city ones at busy times. The installation is one to three days for a home; approval and the bi-directional meter account for the rest.
Do you handle the subsidy and TANGEDCO paperwork?
Yes. We file both the PM Surya Ghar application and the TANGEDCO net metering application, and follow them through the section office covering Vandalur. Timelines at the outer offices vary more than in the city, so we tell you what we are seeing there rather than quoting a standard figure.
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.
Can a college or trust in Vandalur cover most of its bill with solar, the way the zoo does?
Only if most of its consumption happens in daylight and it has the space. A share like the zoo's 80 per cent depends on a daytime-heavy load. A residential college with hostels running fans and lights at night will see a smaller share, so the meter data decides the size, not the example.
I run a shop near the Kilambakkam terminus. How is the solar power I export paid?
Shops are non-domestic connections on net feed-in. Exported units are credited at ₹3.61 each for systems up to 10 kW and ₹3.37 from 11 to 150 kW, well below what you pay for grid power. That is why a shop system should be sized to the load it runs in daylight.
