North Delhi’s belt around Jagatpur, Wazirabad Road, and the Delhi University North Campus area has a distinct DISCOM profile that a lot of solar installers get wrong before they even start the paperwork — this is TPDDL territory, not BSES. On 8 September 2026, Thermosun completed a 3kW rooftop solar installation on Main Jagatpur Road, built on an elevated steel structure engineered to clear two large rooftop water tanks, and paired with a Luminous grid-tied inverter. As the Best Solar Company in Delhi, getting details like the correct DISCOM right from day one is exactly the kind of ground-level accuracy that separates a smooth installation from a delayed one.
Project Overview & Highlights
This Jagatpur Road installation was designed around a terrace already occupied by two large water storage tanks — a common constraint on North Delhi rooftops. Here’s exactly what was delivered:

Rooftops crowded with water tanks and antennas still work well for solar with the right elevated structure. A free site survey confirms the right approach for your terrace.

The terrace on this Jagatpur Road property had two large water tanks positioned close to the most sun-exposed section of the roof — a layout that would have forced a flat-mounted array into partial shade for a good part of the day. Thermosun’s team instead built a tall elevated galvanized steel structure that lifts the entire 3kW array well above both tanks, keeping the panels in direct, unobstructed sunlight from morning through evening.
💧 Water Tanks Are the Most Underrated Shading Problem
Most homeowners worry about shadows from neighbouring buildings or trees, but overhead water tanks on their own roof are just as common a culprit — and easy to miss when estimating solar output from a photo alone. Our site survey specifically checks tank height, position, and the sun’s path through the day before finalising whether a flat mount or an elevated structure is the right call. On this project, the elevated design was the clear choice.
Luminous Inverter — DC/AC Setup Explained
This installation runs on a Luminous grid-tied string inverter, one of the more recognised MNRE-listed inverter brands for Indian residential rooftop solar. It’s installed alongside two separate panel boxes — a DC panel box with isolator and fuse protection on the array side, and an AC panel box with MCB and isolator on the grid side — both routed through surface conduit for a clean, weatherproof finish.
Real Savings — What This Home Now Earns
With the array generating power, the Luminous inverter converting it, and net metering active through TPDDL, here’s the estimated monthly financial picture for this 3kW system:
| Benefit | Monthly Value | Annual Value |
|---|---|---|
| Bill Reduction via Net Metering | ₹2,200 – ₹3,200 | ₹26,400 – ₹38,400 |
| Delhi GBI (₹3/unit generated, up to 3kW slab) | ₹1,000 – ₹1,200 | ₹12,000 – ₹14,400 |
| Total Monthly Financial Benefit | ₹3,200 – ₹4,400 | ₹38,400 – ₹52,800 |
📊 PM Surya Ghar Subsidy + Delhi GBI = Major Government Support
One-time PM Surya Ghar subsidy of ₹78,000 for this 3kW system, credited directly to bank account post-commissioning, plus a Delhi state capital subsidy of ₹6,000 (₹2,000/kW) adjusted in the first bill. On top of that, Delhi GBI adds ₹3/unit generated for 5 years at this system size.
Combined government support on this installation comes to roughly ₹1.44–1.56 lakh over the full 5-year GBI period, bringing payback down to just a few years. After that, this Jagatpur Road home generates free solar energy for another 20+ years.
Why TPDDL Customers Shouldn’t Assume the BSES Process
Delhi’s rooftop solar customers commonly assume every property falls under BSES Rajdhani or BSES Yamuna, since those two DISCOMs cover the majority of the city. But North and North-West Delhi — including Jagatpur, Wazirabad Road, Model Town, Rohini, and Pitampura — is Tata Power Delhi Distribution Limited (TPDDL) territory, with its own separate net-metering portal, inspection process, and application format.
⚡ What’s Different With TPDDL
TPDDL runs its own online application and tracking system distinct from the BSES consumer portal. Filing net-metering paperwork through the wrong system, or assuming BSES’s turnaround times apply here, is a common source of delay for installers unfamiliar with this zone. Thermosun’s team filed this Jagatpur Road application directly through TPDDL’s correct channel from the outset.

Knowing which DISCOM actually serves a property — and filing through the correct portal from the first day — sounds basic, but it’s exactly where inexperienced installers lose weeks on net-metering delays. Combined with roof-specific engineering like the elevated structure used here to clear two water tanks, this is the kind of detail-level accuracy that comes from 1,000+ completed installations across every DISCOM zone in Delhi. Thermosun is the solar epc company in Delhi because every project — BSES or TPDDL territory — gets handled through the right channel from day one, not a generic assumption.

Frequently Asked Questions
Is Jagatpur Road served by BSES or TPDDL?
Jagatpur, Wazirabad Road, and the surrounding North Delhi belt fall under Tata Power Delhi Distribution Limited (TPDDL), not BSES Rajdhani or BSES Yamuna. Net-metering applications here are filed through TPDDL’s own portal.
Can solar panels be installed on a roof with large water tanks?
Yes — with an elevated structure designed to clear the tanks’ height and position. This Jagatpur Road installation used exactly this approach to keep the full array in direct sunlight despite two large tanks on the terrace.
How much subsidy does a 3kW system get under PM Surya Ghar?
A 3kW system qualifies for the full ₹78,000 central subsidy — the exact system size where the subsidy structure reaches its maximum before capping.
Is Luminous a reliable inverter brand for residential solar?
Yes — Luminous is a well-established, MNRE-listed grid-tied inverter brand widely used in Indian residential rooftop solar installations, including this Jagatpur Road project.
Does the net-metering process take longer with TPDDL than BSES?
Not inherently — but the application must go through TPDDL’s own system rather than the BSES consumer portal. Delays typically happen when installers unfamiliar with the zone file through the wrong channel, not because TPDDL itself is slower.
How much can a Jagatpur Road household save monthly with a 3kW system?
Based on this installation, combined bill reduction and Delhi GBI income comes to approximately ₹3,200-₹4,400 per month, depending on actual generation and household consumption.
Conclusion
This Jagatpur Road installation is a good reminder that solar installation in Delhi isn’t one uniform process — DISCOM territory changes the paperwork channel, and rooftop obstructions like water tanks change the mounting design. Getting both right the first time, with a correctly engineered elevated structure and the correct TPDDL application, is what made this a clean 3kW installation. For homeowners in Jagatpur, Wazirabad Road, or anywhere across North Delhi’s TPDDL zone considering solar installation near me, a free site survey is the fastest way to get accurate answers specific to your roof and DISCOM.
