Homes
Rooftop solar for homes in Deoghar
We size the system to your actual bill, file your PM Surya Ghar subsidy (up to ₹78,000) and check the installer’s work, so your bill falls the way it should.
Quick check
Is home solar right for you?
You own the roof
Or have the written consent of the owner or society. The subsidy is tied to the electricity connection in your name.
Your bill is above ₹1,500
Below that, payback stretches out. Above ₹1,500 a month, solar usually pays for itself well within its life.
About 100 sq ft per kW
Shade-free terrace space. A 3 kW system needs roughly 300 sq ft clear of tanks, stairwells and tree shadow.

System types
On-grid, hybrid or off-grid: which fits?
On-grid
Connected to the DISCOM grid through a net meter. Extra daytime units are exported and credited against your bill. No batteries, so the lowest cost per unit.
Best for: Most homes with reliable grid supply. The only type that qualifies for the PM Surya Ghar subsidy.
Hybrid
Grid-connected like on-grid, plus a battery bank that keeps essential loads running during power cuts.
Best for: Areas with frequent outages where backup for fans, lights, Wi-Fi and a fridge matters.
Off-grid
Runs entirely on panels and batteries with no grid connection. Batteries are sized for cloudy days, which raises cost.
Best for: Farmhouses and sites where a grid connection is unavailable or very unreliable.
Sizing guide
What size system for your bill?
Worked out with the same logic as our calculator. Your site survey replaces these estimates with exact figures for your roof.
| Monthly bill | Approx. units / month | Suggested size | Roof area (approx.) | Est. generation / month |
|---|---|---|---|---|
| ₹1,500 | 200 | 2 kW | 200 sq ft | 230 units |
| ₹2,500 | 330 | 3 kW | 300 sq ft | 350 units |
| ₹4,000 | 530 | 5 kW | 500 sq ft | 590 units |
| ₹6,000 | 800 | 7 kW | 700 sq ft | 820 units |
| ₹9,000 | 1,200 | 10.5 kW | 1,050 sq ft | 1,230 units |
Estimates based on regional sunshine for Jharkhand, typical tariffs and ~100 sq ft per kW. Sized to cover your energy units; fixed and meter charges on the bill remain. Not a quote.

What size system does my home need?
It depends on your monthly units, not the size of your house. As a rough guide, each kW in most of India generates around 110–140 units a month. We work it out from 12 months of bills so the system covers your real usage without overspending on panels you don’t need.
Can I get the subsidy if my house is in a housing society?
Individual flat owners usually can’t use the common terrace on their own. The society can install a common-area system and claim group-housing support (₹18,000 per kW). If you own an independent house or a top-floor terrace with rights, you can apply individually.
Do I need batteries?
Not for savings. An on-grid system with net-metering saves the most and is the type the PM Surya Ghar subsidy covers. Add batteries (hybrid) only if power cuts are a real problem where you live.
Why use a consultant instead of going straight to an installer?
An installer’s quote is also their sales pitch. We are paid for advice, so we size the system honestly, compare quotes line by line and check the work on site. That usually saves more than our fee and avoids the common mistakes that delay subsidy.
