Solar Panel Installation in Padur
Residential campuses sized on their real load, not on a day college template
Padur’s campuses are residential, and that makes them a different proposition from a day college. Hostels run through the evening, the night and much of the vacation, which means the load profile looks nothing like the term-time-daytime pattern most campus proposals are built on.

The short answer
Looking for a solar panel installation company in Padur?
In Padur we work on both independent terraces and apartment common areas, and the two need different paperwork even on the same street. Because it is a newer area, roofs here are generally in good condition and the paperwork moves faster than the average. We have installed across Chennai since 2020, file the PM Surya Ghar subsidy of up to ₹78,000 for households and the TANGEDCO net metering application ourselves, and include two years of free 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 Padur.

The local picture
Why a hostel campus is not a day college
Padur’s educational institutions are largely residential, with hostel accommodation alongside teaching buildings, and that changes the solar arithmetic considerably. A day college consumes almost entirely within generating hours and drops to near zero during vacation. A residential campus consumes through the evening and night, continues consuming during much of the vacation, and carries a far higher baseline from kitchens, water heating, pumps and hostel lighting.
What that means for a proposal
Not all annual consumption is addressable
A significant share falls outside generating hours. Kitchen equipment, water heating and hostel lighting run in the evening and at night. A proposal presenting total annual consumption as offsettable is overstating what the system will do.
The vacation helps rather than hurts here
Unlike a day college, a residential campus with continuing occupancy through part of the vacation has somewhere for summer generation to go, which is precisely when generation peaks. That makes the sizing less punishing than for a purely day institution.
The trust tax position applies as elsewhere
Most institutions here operate as trusts, and accelerated depreciation is worth nothing without taxable income to offset. Where that applies, an OPEX or RESCO structure often compares better than ownership, and it should be checked with the institution’s auditor.
Installation is best scheduled in vacation
And because approvals take weeks, the audit and design need starting months ahead.

Local guide
Rooftop solar in Padur: planning around the lake and the canal
Padur sits on OMR about 2 km from the Siruseri IT Park, and its low-lying streets drain through Padur Lake towards the Buckingham Canal. In November 2021 about 500 houses here were cut off by waist-deep water, and that history decides where the electrical parts of a solar system should sit.
Water that waits for the Buckingham Canal
Padur floods differently from most of OMR. When DT Next reported the November 2021 floods, residents said the water did not drain when the rain stopped. It stood for days and receded only when the level in the Buckingham Canal came down. More than half the roads had up to 4 ft of water, and Padur Lake, which an activist described as the outlet for over seven lakes upstream, overflowed. The Times of India reported lake water running across OMR from west to east. In April 2026 a resident told Citizen Matters there are still missing stormwater drain links between Padur and Okkiyam Maduvu. Plan for standing water lasting days, not a flash flood.
Putting the inverter above the 2021 water line
On a ground-floor house here, the inverter, the solar distribution box and the AC isolator should not sit on the ground-floor wall. We record the highest water mark on your compound wall or ask what the 2021 level was, then mount the electronics at least a metre above it, usually on the first-floor wall or on the terrace under a headroom or the elevated structure, in shade. The net meter stays where TNPDCL fits it, but everything we own goes up. If water does enter the house, the system can be switched off at the terrace and restarted once the power is restored.
Sizing a Padur home on the Chengalpattu figure
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 here makes about 4,740 units a year, roughly 790 per bi-monthly billing cycle. A 5 kW system makes about 7,900 units a year, about 1,320 a cycle. Anything above 4 kW needs a three-phase connection, so check your service before choosing 5 kW. On price, 3 kW costs about ₹2,10,000 before subsidy and about ₹1,10,000 after the central and Tamil Nadu subsidies. What remains on the bill for a home is mainly the network charge of about ₹0.32 a unit on generation.
Shops and clinics on the OMR frontage
Padur's OMR frontage has shops, eateries and clinics serving the campuses and the apartment communities. These are non-domestic connections, so they are on net feed-in rather than net metering. Power used on site saves the full tariff, but exported units are credited at ₹3.61 a unit up to 10 kW and ₹3.37 from 11 to 150 kW. That favours a system sized to daytime use, not to roof area. A clinic open from morning to evening is a good match. A restaurant that peaks after sunset is not, and should be sized to its lunchtime kitchen and cold storage load.

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 Padur?
Been shown a proposal covering your full annual consumption?
On a hostel campus that overstates it. Night load cannot be served by solar without storage, and we say so.
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 Padur, common questions
How is a residential campus sized differently from a day college?
A day college consumes almost entirely within generating hours and drops to near zero during vacation, so it is sized to term-time daytime load. A residential campus consumes through the evening and night and continues through much of the vacation, so it is sized against annual load excluding the night portion, which solar cannot serve without storage.
Can solar cover a hostel campus’s full electricity bill?
No. Kitchen equipment, water heating and hostel lighting run in the evening and at night, outside generating hours. A proposal presenting total annual consumption as offsettable is overstating what the system will do. What solar covers well is the daytime baseline, which on a residential campus is substantial.
Can a trust-run college claim accelerated depreciation?
Only if it has taxable income to offset. Most institutions here operate as trusts or societies, and depreciation is a deduction against taxable profit, so it is worth nothing to an entity without a tax liability. Where that applies, an OPEX or RESCO arrangement often compares better than ownership. Check with your auditor before evaluating any proposal.
How long does installation take in Padur?
Six to eight weeks from survey to a live, net-metered system is typical in Padur, 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 Padur 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.
My Padur street flooded in 2021. Can the inverter go on the terrace instead?
Yes, and on flood-prone streets here it is often the best place. We put it in a shaded, ventilated spot on the terrace, under a headroom or the elevated structure, in a weather-rated enclosure. The DC cables stay short and nothing electrical sits where water stood for days in 2021.
Does Padur generate less than Chennai city?
Very slightly. Padur is in Chengalpattu district, where the state calculator uses 1,580 units per kW a year against 1,600 for Chennai district, a difference of about 1%. A 5 kW system here makes about 7,900 units a year instead of 8,000.
