Maruti Kunj sits right at the Delhi–Gurugram border, and this project came with a common challenge in growing NCR neighbourhoods: an under-construction terrace, future building activity around the property, and a homeowner who wanted the system future-proofed rather than fitted around today’s constraints alone.
On 14 August 2026, Thermosun completed a 5kW hybrid residential solar installation here — panels raised on a tall galvanized-iron A-frame structure, paired with a Deye hybrid inverter and battery backup. As the best solar company in Delhi NCR, this is exactly the kind of site-specific engineering we bring to every project, whether it’s in the city or the fast-developing Gurugram belt.
Why an Elevated Mounting Structure Was the Right Call
Standard rooftop solar uses a low-angle frame sitting close to the roof slab. But this Maruti Kunj terrace had ongoing construction — brick stacks, debris, and future floor-raising plans — which meant a low structure would eventually sit in someone’s way, or worse, end up shaded by a future extension.
🏗️ How Thermosun Solved This
We installed a heavy-duty galvanized-iron A-frame structure that raises the panel array roughly 8 feet above the terrace floor. This clears all current obstructions, keeps the array above any likely future construction line, and leaves the full terrace usable underneath — a two-in-one solution common on plots where the homeowner is still building out the property.

Thermosun’s engineers plan mounting structures around your future construction — not just today’s rooftop. Free site survey includes structural and shadow planning.
Inside the System — Deye Hybrid Inverter & Battery Backup
The second photo shows what makes this installation different from a standard on-grid setup: a Deye hybrid inverter paired with a dedicated lithium battery unit, alongside a solar AC DB and DC DB, both fitted with surge protection devices (SPD). This configuration means the home doesn’t just save on its electricity bill — it keeps essential loads running during a grid outage too.
| Component | Detail |
|---|---|
| Inverter | Deye hybrid inverter with digital display & monitoring |
| Battery | Deye lithium battery unit for backup power |
| Solar AC DB | MCB-protected distribution box with SPD |
| DC DB | DC isolator box with surge protection |
| Wiring | Fully conduit-routed DC & AC cable runs |
Real Savings — What This Home Now Earns (and Keeps During Outages)
A 5kW system in this belt generates roughly 18–22 units per day on a clear day, enough to cover a household consuming 500–600 units a month and cut the bill by 80–90%. The difference here is the battery: instead of losing power the moment the grid trips, essential loads — lights, fans, WiFi, refrigerator — stay on, drawing from stored solar energy.

Why Thermosun Is the Best Solar Company in Delhi NCR
This Maruti Kunj project shows two things that set experienced installers apart: designing for the property’s future, not just its present, and recommending a hybrid system when battery backup genuinely adds value. A less experienced vendor might have quoted a low-angle mount and skipped the backup conversation entirely — Thermosun engineered around both from day one, the way the best solar company in Delhi NCR should.
Delhi NCR’s monsoon and dust also affect long-term panel output — we cover this in detail in Do Solar Panels Work in Rain?, and the same solar panel maintenance routine applies to hybrid systems like this one.

Frequently Asked Questions
What is a hybrid solar inverter and do I need one?
A hybrid inverter, like the Deye unit used in this Maruti Kunj project, can run loads from the grid, solar, or a connected battery. It’s the right choice if you want power backup during outages, not just bill savings.
Why raise the solar structure 8 feet above the roof?
On plots still under construction, a low-mounted system risks future shading or needing to be moved. An elevated galvanized-iron structure clears current obstructions and future building lines in one go.
How much does a 5kW solar system with battery backup cost?
A hybrid system with battery costs more than a standard on-grid 5kW setup due to the battery and hybrid inverter. See our 5kW pricing guide for on-grid baseline costs, and contact us for a hybrid-specific quote.
Does Thermosun install solar systems outside Delhi, like in Gurugram?
Yes. As the best solar company in Delhi NCR, Thermosun installs across Delhi, Noida, Gurugram, Ghaziabad, and Faridabad — this case study is from a project in Maruti Kunj, Gurugram.
Conclusion
The Maruti Kunj installation shows what forward-looking solar design looks like: an elevated structure that won’t need to be redone as construction continues, and a hybrid inverter with battery backup that keeps the home powered through outages, not just sunny days. It’s a system built for the next 25 years, not just the day it was switched on.
