Large independent houses and farmhouses in South Delhi — especially in areas like Sainik Farm — run electricity loads that a standard 2-3 kW rooftop system simply can’t offset. Multiple split ACs, lawn and garden pumps, guest wings, and often a home office all draw power through the day. On 25 August 2026, Thermosun completed a 10kW rooftop solar installation at a Sainik Farm property, engineered specifically for this kind of high-consumption household. As the Best Solar Company in Delhi, Thermosun brings the same engineering precision to every project — whether it’s a 2kW DDA flat system or a 10kW farmhouse installation like this one.
Project Overview & Highlights
This Sainik Farm installation was designed around a large open terrace with ample shadow-free area — ideal for a high-capacity system. Here’s exactly what was delivered:
Farmhouse or Large Independent House in Delhi?
Bigger roof spaces and open sky exposure make properties like Sainik Farm, Chhattarpur, and Vasant Kunj farmhouses ideal for high-capacity solar — a free site survey tells you exactly how much you can save.

The defining visual feature of this installation is the elevated galvanized steel frame — a structure that lifts the entire 10kW panel array several feet above the rooftop on angled steel columns. On a farmhouse-style property, this wasn’t a cosmetic choice.
🏡 Large Independent Houses — Unique Rooftop Considerations
Farmhouse and independent-house terraces in Delhi often have water tanks, existing structures, boundary walls, and usable space underneath that owners want to keep functional (parking, seating, storage). A flat, low-mounted solar array would either shade part of the array itself or block that usable space entirely. Thermosun’s site survey for this Sainik Farm property confirmed that an elevated structure was the only design that maximised full-day sun exposure across all 10kW of panels while keeping the terrace below fully usable — exactly what’s visible in the completed installation.
Inverter & DC/AC Safety Setup Explained
A 10kW system needs a string inverter sized to match, along with a complete safety chain on both the DC (panel) side and AC (grid) side. This installation used an MNRE-listed grid-tied string inverter [confirm exact brand/model to insert here], paired with a DC panel box (fuse, disconnect switch, surge protection device) and an AC panel box (MCB, isolator, SPD) — the same safety architecture required for DISCOM net-metering approval on any grid-connected system in Delhi.
Real Savings — What This Property Now Earns
With the array generating power, the inverter converting it, and net metering active through BRPL, here’s the estimated monthly financial picture for a 10kW system at this consumption level:
| Benefit | Monthly Value | Annual Value |
|---|---|---|
| Bill Reduction via Net Metering | ₹9,000 – ₹12,000 | ₹1,08,000 – ₹1,44,000 |
| Delhi GBI (₹2/unit generated, 3–10kW slab) | ₹2,400 – ₹2,700 | ₹28,800 – ₹32,400 |
| Total Monthly Financial Benefit | ₹11,400 – ₹14,700 | ₹1,36,800 – ₹1,76,400 |
📊 PM Surya Ghar Subsidy + Delhi GBI = Major Government Support
One-time PM Surya Ghar subsidy of ₹78,000 (capped for any system 3kW and above) credited to bank account post-commissioning, plus a Delhi state capital subsidy of up to ₹10,000 adjusted in the first bill. On top of that, Delhi GBI adds ₹2/unit generated for 5 years — on a 10kW system, that’s roughly ₹1.44–1.62 lakh in GBI income alone over 5 years.
Combined government support on this installation exceeds ₹2.3–2.5 lakh, substantially reducing the effective cost and shortening payback to well within 4–5 years. After payback, this Sainik Farm property generates essentially free solar energy for another 20+ years.
Why Farmhouses & Large Independent Houses in Delhi Are Ideal for Solar
Properties in areas like Sainik Farm, Chhattarpur, and similar farmhouse belts have structural advantages that smaller urban apartments simply don’t:
🏠 Larger Roof Areas — More Panel Capacity
Independent farmhouses in Delhi typically have 1,000+ sq. ft. of usable, shadow-free rooftop — several times what a standard apartment offers. More usable area means a higher-capacity system is possible, translating to bigger monthly savings and faster payback on the overall solar panel installation cost.
⚡ Higher Baseline Consumption
Farmhouse properties typically run more ACs, pumps, and outdoor lighting than a standard flat — meaning a bigger system directly offsets a proportionally larger bill, making the economics of a 10kW residential solar installation even stronger.

A 10kW installation isn’t a scaled-up version of a small rooftop system — it demands correct load calculation, a structurally sound mounting design, and clean DISCOM paperwork, since larger systems draw more scrutiny during inspection. Getting the elevated structure right, selecting the correct inverter for the load profile, and managing net-metering for a high-capacity connection all require the kind of ground-level Delhi experience that comes from 1,000+ completed installations across the city. Thermosun is the solar epc company in Delhi not just because we install well, but because we design specifically for each property rather than applying a one-size-fits-all template.

Frequently Asked Questions
Is a 10kW solar system suitable for a farmhouse or independent house in Delhi?
Yes — properties with 900+ sq. ft. of shadow-free roof and high daily consumption (900-1,200+ units/month) are ideal candidates. Farmhouse-style properties in Sainik Farm, Chhattarpur, and similar belts typically have both.
How much subsidy applies to a 10kW system under PM Surya Ghar?
The central subsidy caps at ₹78,000 for any system 3kW and above — a 10kW system receives the same fixed amount as a 3kW system. The value comes from the larger system generating far more units, plus Delhi’s additional state subsidy and GBI.
What is Delhi GBI and does it apply to a 10kW system?
Delhi’s Generation-Based Incentive pays ₹3/unit for systems up to 3kW and ₹2/unit for systems between 3kW and 10kW, for 5 years from commissioning. A 10kW system like this one qualifies at the ₹2/unit rate.
Why was an elevated structure used instead of a standard flat mount?
The property’s terrace had existing structures and usable space the owner wanted to keep functional. An elevated steel frame maximises sun exposure for all panels while leaving the terrace below usable — common for larger independent houses.
How long does net metering approval take for a 10kW system with BRPL?
Larger systems can take slightly longer than small residential ones due to additional technical review, but Thermosun’s direct liaisoning typically gets net metering commissioned within 3-5 weeks of installation.
How much can a Sainik Farm property save monthly with a 10kW system?
Based on this installation, combined bill reduction and Delhi GBI income comes to approximately ₹11,400-₹14,700 per month, depending on actual generation and consumption patterns.
Conclusion
This Sainik Farm installation confirms what Thermosun’s team sees consistently across Delhi: solar economics get stronger, not weaker, as system size and property scale increase — provided the engineering is done right. Getting the mounting structure correct for the specific roof, sizing the inverter to the load, and completing net metering and subsidy paperwork properly the first time is what separates a smooth 10kW installation from a problematic one. For farmhouse and large independent-house owners in Sainik Farm, Chhattarpur, or anywhere in Delhi NCR wondering whether a high-capacity system makes sense — start with a free site survey. The numbers usually make the decision clear.
