Not every Thermosun project is inside Delhi’s own DISCOM boundaries — a large part of Delhi NCR’s solar demand comes from Ghaziabad, Noida, and Gurugram, where the rules, DISCOMs, and even the subsidy structure work differently. On 11 September 2026, Thermosun completed a 10kW commercial rooftop solar installation on an under-construction commercial property in Lajpat Nagar, Ghaziabad, right alongside a Delhi Metro corridor. As the Best Solar Company in Delhi and across the wider NCR region, Thermosun applies the correct state-specific process whether a project sits in Delhi, Ghaziabad, Noida, or Gurugram — not a copy-paste of Delhi’s rules onto a UP project.
Project Overview & Highlights
This Ghaziabad installation was built on an active commercial construction site, with the solar structure erected before the building below was even fully finished. Here’s exactly what was delivered:

This property was still under construction when the solar structure went up — visible in the bare RCC columns and unfinished flooring beneath the array. Rather than waiting for the building to be fully completed, Thermosun’s team designed a heavy-duty steel truss that could be anchored into the structural columns already in place, positioned to clear the neighbouring elevated metro corridor’s shadow line through the day.
🏗️ Designing Solar Around an Unfinished Building
Installing solar on a property mid-construction requires coordinating with the structural engineer’s column and beam layout rather than a finished rooftop slab. The truss on this project was engineered to distribute load onto load-bearing columns already cast, so the array could go live without waiting for the rest of the building’s construction timeline — a common request from commercial property developers who want solar generation running from day one of occupancy.
Sungrow Commercial Inverter Setup Explained
This installation runs on a Sungrow grid-tied inverter, sized for the 10kW commercial load, paired with dedicated DC and AC panel boxes for isolation and protection. Sungrow is one of the widely used inverter brands for commercial and industrial-scale rooftop solar in India, chosen here for its efficiency at this system size and compatibility with PVVNL’s net-metering requirements.
Commercial Solar Economics — No Subsidy, Still Strong ROI
⚠️ Important: PM Surya Ghar Does Not Apply Here
PM Surya Ghar Muft Bijli Yojana is a residential-only scheme. This installation is on a commercial/industrial property, so it does not qualify for the ₹78,000 central subsidy or any UPNEDA residential state subsidy. The return on this installation comes entirely from electricity bill savings, net-metering export credit, and tax depreciation benefits — not a government cash subsidy.
With the array generating power and net metering active through PVVNL, here’s the realistic financial picture for a 10kW commercial system at typical commercial tariff rates:
| Benefit | Estimated Value |
|---|---|
| Expected generation | ~1,260 – 1,350 units/month |
| Monthly bill offset (commercial tariff) | ₹10,000 – ₹13,500 |
| Annual bill offset | ₹1,20,000 – ₹1,62,000 |
| Accelerated depreciation (Year 1, per Income Tax Act) | Up to 40% of system cost as depreciation, reducing taxable business income |
📊 How Commercial Solar Pays Back Without a Subsidy
Unlike residential systems, commercial and industrial solar installations in India can claim accelerated depreciation of up to 40% of the system’s value in the first year under the Income Tax Act — a substantial tax shield that residential consumers don’t have access to. Combined with direct bill savings and net-metering export credit at PVVNL’s applicable rate, a 10kW commercial system like this one typically pays back within 4-5 years purely through operational savings and tax benefit — even with zero cash subsidy involved.
Why This Is PVVNL Territory, Not a Delhi DISCOM
Ghaziabad falls under Paschimanchal Vidyut Vitran Nigam Limited (PVVNL), one of Uttar Pradesh’s DISCOMs — not BRPL, BYPL, TPDDL, or NDMC, which only cover Delhi proper. This matters for three reasons: the net-metering application goes through PVVNL/UPPCL’s own system, the applicable subsidy framework is UPNEDA’s (not Delhi’s), and even feed-in tariff rates for exported units follow UPERC (Uttar Pradesh Electricity Regulatory Commission) rules rather than Delhi’s DERC.
📍 A Common NCR Mix-Up
Properties along the Delhi-Ghaziabad border, especially near metro corridors that visually feel like “Delhi,” are still governed by UP’s DISCOMs and policies once they cross the state line. Assuming Delhi’s PM Surya Ghar residential subsidy or Delhi’s Generation-Based Incentive applies here would be a straightforward but costly mistake for a property owner to make.

A commercial installation on an active construction site, in a different state’s DISCOM territory, with no subsidy to lean on, is exactly the kind of project that separates an installer who only knows Delhi’s rules from one who operates across the full NCR region correctly. Thermosun is the best solar EPC company in Delhi and across NCR because our team designs the structure, files with the correct DISCOM — Delhi or UP — and gets the commercial economics right, whether that means a subsidy application or a depreciation-driven ROI case like this one.

Frequently Asked Questions
Does PM Surya Ghar subsidy apply to commercial solar in Ghaziabad?
No. PM Surya Ghar is a residential-only central government scheme. Commercial and industrial properties, including this Ghaziabad installation, don’t qualify for it regardless of location.
Which DISCOM handles net metering in Ghaziabad?
Ghaziabad falls under PVVNL (Paschimanchal Vidyut Vitran Nigam Limited), one of Uttar Pradesh’s DISCOMs. Applications go through UPPCL’s system, separate from Delhi’s BRPL, BYPL, or TPDDL.
How does a commercial solar system pay back without a subsidy?
Through direct electricity bill savings, net-metering export credit, and accelerated depreciation of up to 40% of the system value in the first year under the Income Tax Act — a tax benefit specific to businesses, not available to residential consumers.
Can solar be installed on a building that’s still under construction?
Yes, with a structure designed around the existing structural columns and beams — as done on this project — so the solar system can go live independently of the rest of the building’s completion timeline.
Is UP’s solar subsidy structure the same as Delhi’s?
No. Delhi runs its own state capital subsidy and Generation-Based Incentive under the Delhi Solar Energy Policy. UP’s residential support comes through UPNEDA, and the two should never be assumed interchangeable — this is especially relevant for NCR properties near the Delhi-UP border.
Does Thermosun install solar outside Delhi, in Ghaziabad or Noida?
Yes — Thermosun serves the full Delhi NCR region, including Ghaziabad, Noida, and Gurugram, handling the correct state-specific DISCOM and subsidy process for each location.
Conclusion
This Ghaziabad installation is a useful reminder that “Delhi NCR solar” isn’t a single uniform process — cross a state line and the DISCOM, subsidy framework, and even the applicable tax benefits change. Getting the structural design right for an active construction site, filing correctly with PVVNL instead of a Delhi DISCOM, and setting accurate expectations around depreciation-driven ROI rather than a residential subsidy is what made this a clean 10kW commercial installation. For commercial or industrial property owners in Ghaziabad, Noida, Gurugram, or anywhere across NCR considering rooftop solar installation, a free site survey is the fastest way to get the numbers right for your specific state and property type.
