Solar Panel Installation in Siruseri
We establish who controls the roof before anything gets designed
Siruseri is an IT SEZ, and that makes the roof question unusually complicated. Buildings are large, roofs are substantial, and the company occupying the floor is very often not the party that controls the terrace above it.
Installing across Chennai since 2020
Two years free maintenance included
Subsidy and TANGEDCO paperwork filed by us
Free site survey and energy audit, no obligation
The short answer
Looking for a solar panel installation company in Siruseri?
Most enquiries from Siruseri are commercial, where the tariff category and sanctioned demand decide the system long before the roof does. Because it is a newer area, roofs here are generally in good condition and the paperwork moves faster than the average. 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 Siruseri.

The local picture
Campus buildings and who controls the roof
Siruseri’s IT park and SEZ buildings are typically developer-owned and let to occupying companies, sometimes floor by floor. That means the tenant with the electricity bill frequently has no rights over the roof, while the party that controls the roof does not pay the electricity bill. Resolving that split is the first step in any Siruseri commercial solar project.
The three parties and what each needs
The occupying company
Pays the electricity bill and wants the saving, but usually cannot install without the building owner’s agreement.
The building owner or developer
Controls the roof but may not benefit directly from a reduced tenant bill unless the arrangement is structured for it.
The park or SEZ administration
May have its own requirements on structures, appearance and electrical alterations.
Structures that work in this situation
Owner-led installation with the benefit passed through the lease
Usually the cleanest arrangement in a multi-tenant building.
An OPEX or RESCO structure
Where a developer funds and owns the system, which can align to lease terms more comfortably than tenant ownership.
Single-tenant buildings
Where the occupier holds the whole building and the position is simpler.
The technical picture on IT park roofs
Usable area is well below gross
Chillers, air handling units, condenser banks and lift machine rooms occupy space, cast shade and need maintenance access preserved around each. We measure usable area rather than working from a floor plate figure.
The load profile is favourable, with two caveats
Demand charges and net feed-in
Office consumption sits squarely in working hours, close to an ideal solar match, and commercial tariffs make each displaced unit worth more. But solar does not reduce demand charges, which on a large commercial connection remain substantial, and non-domestic consumers are generally on net feed-in rather than net metering.

Local guide
Solar in Siruseri: SIPCOT campuses and the townships beside them
SIPCOT's IT park at Siruseri covers about 780 acres, and its campuses draw power in megavolt-amperes with diesel backup to match. That scale, and the large apartment townships built beside the park for its workforce, set the solar questions here.
Campus loads measured in MVA, with diesel standing by
The environmental filing for the expansion of TCS's Siruseri campus gives a sense of scale: 20 MVA of supply from the grid in operation, 14 diesel generators of 2,000 kVA each on standby, and about 25,200 people a day once expanded. A rooftop array on a campus like this offsets a slice of the daytime load, and larger shares come from captive or open access supply. The design point specific to these sites is the generators. When the grid fails and the DG sets start, a rooftop inverter on the same bus must not push power back into them. A campus array here needs a DG synchronisation or zero-export controller that throttles the inverters during DG operation, specified at the design stage.
Townships next to the park: check the metering first
Residential growth around Siruseri has largely been large townships for the IT workforce. L&T Eden Park spreads over 92 acres beside the park, with high-rise towers and its own substation for the township. For associations in towers like these, the common-area route at ₹18,000 per kW covers lifts, pumps, the STP and lighting, but the roof of a tall tower is small against what it serves. Before anything is designed, confirm how the common areas are billed: on an LT service of their own, or through the township's own substation arrangement. That decides which metering route a common-area system can take. Villa owners with individual connections follow the household route; a 5 kW system costs about ₹3,20,000, about ₹2,20,000 after both subsidies, and makes about 7,900 units a year here.
OMR drainage and where the electrical rooms sit
The Siruseri stretch sits on a corridor with a known drainage problem. After Cyclone Michaung in December 2023, the Times of India reported that OMR is low-lying, that the 20 km of highway stormwater drains laid in 2008 were inadequate for today's run-off, and that ground floors flooded in Thoraipakkam, Sholinganallur, Karapakkam and Perungudi further north. For a campus or township array, that argues for keeping string inverters and combiner boxes on the roof or on an upper plant floor, not in basement or ground-floor electrical rooms, and for routing the AC cable down risers rather than through ground-level ducts that can fill with water.

- No obligation at any point. If solar does not make sense for your property, we will say so.
Common questions
Solar in Siruseri, common questions
Can a tenant install solar on an IT park building in Siruseri?
Not without the building owner’s agreement. Park and SEZ buildings are typically developer-owned and let floor by floor, so the company paying the electricity bill frequently has no rights over the roof. The workable routes are an owner-led installation with the benefit passed through the lease, or an OPEX arrangement where a developer owns the system.
How much usable roof does an IT park building have?
Considerably less than the gross area suggests. Chillers, condenser banks, air handling units and lift machine rooms occupy space, cast shade and need maintenance access preserved around them. We measure usable area rather than working from a floor plate figure.
Will solar remove our office electricity bill?
No. Solar reduces the energy charge on units generated during working hours, which for an office is a substantial share since consumption matches generation well. It does not reliably reduce demand charges, which are levied on sanctioned or recorded maximum demand, and non-domestic consumers are generally on net feed-in rather than one-for-one net metering.
How long does installation take in Siruseri?
Eight to fourteen weeks for a commercial property in Siruseri, compared with six to ten for a house. The approval path is longer for non-domestic connections, and installation is scheduled around trading hours.
Do you handle the subsidy and TANGEDCO paperwork?
For homes, yes. For the commercial connections common in Siruseri, there is no PM Surya Ghar subsidy, so what we file is the TANGEDCO net metering or net billing application, and we supply the invoice and commissioning documents needed for accelerated depreciation and GST input credit.
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 campus has large DG sets. What happens to the solar plant when the grid fails?
Without a controller, the inverters would try to keep feeding the building while the DG sets run, which can push reverse power into the generators. A DG synchronisation controller reduces or stops solar output whenever the DG is on. It should be part of the design from the start, not added later.
Does Siruseri get the same solar generation as Chennai city?
Almost. The state rooftop calculator gives Chengalpattu district 1,580 units per kW a year against 1,600 for Chennai, a difference of about one percent. A 3 kW home system here makes about 4,740 units a year.
