Before you book a single solar panel, you have to settle one question: what kind of system do you actually need? On-grid, off-grid and hybrid setups use similar panels but behave very differently — in price, in how they handle a power cut, and in whether they qualify for government subsidy. Picking wrong means either overpaying for batteries you don't need or being left in the dark when DHBVN supply drops.
This guide walks through all three so you can match the system to how your household in South Haryana actually uses electricity.
The Short Version
If you have a reasonably stable DHBVN connection and you want the cheapest, fastest-payback route, you want on-grid. If you want the lights to stay on through outages, look at hybrid. Off-grid is a niche choice for places the grid doesn't reach. The sections below explain why.
On-Grid (Grid-Tied) Systems
An on-grid system has no battery. Your panels feed your appliances directly, and anything left over flows back into the DHBVN grid through a bi-directional net meter.
What happens through a typical day:
- Through daylight hours the panels run your home and push the surplus onto the grid
- The net meter records those exported units as credit
- After sunset, or on an overcast monsoon afternoon, you pull from the grid like any other consumer
- At billing time DHBVN charges you only for the net — units drawn minus units exported
Because there's no battery to buy or replace, on-grid is the lowest-cost option and the only one that maximises the PM Surya Ghar central subsidy (up to ₹78,000). Payback typically lands around 3-4 years once the subsidy is credited.
The trade-off is simple: when the grid goes down, an on-grid system shuts itself off. This is a mandatory safety feature — it stops your panels from back-feeding a line that DHBVN linemen may be repairing. So during an outage you get no solar power either.
For most homes in Faridabad, Palwal and Gurugram, on-grid is the sensible default. It's the cheapest path to a low bill, and DHBVN net metering credits your exported units against what you consume.
Off-Grid Systems
An off-grid system is deliberately disconnected from DHBVN entirely. A battery bank stores the day's surplus so the house can run at night purely on stored solar.
The flow is self-contained: panels power the home and charge the batteries by day, and after dark the inverter draws from those batteries. There is no grid in the picture at all.
The appeal is total independence and zero electricity bills. The cost of that independence is steep, though. Batteries are expensive, they wear out in roughly 8-10 years even with lithium chemistry, and you have to size the whole system for your worst week of the year — think a stretch of heavy monsoon cloud — which means buying more panels and storage than you'll use most days. Crucially, off-grid systems are not eligible for PM Surya Ghar subsidy, because the scheme requires a grid connection and net metering.
Realistic use case: farmhouses on the rural edges of Palwal, agricultural pump sets, or any plot where extending a reliable line is impractical.
Hybrid Systems
A hybrid system is the middle path: it stays connected to DHBVN for net metering and carries a battery for backup.
Across a day it behaves like this:
- Panels run the house during daylight
- Surplus first tops up the battery, then exports to the grid for net-metering credit
- If the grid fails, the battery seamlessly keeps your essential circuits alive
- After dark the home draws from the battery first, falling back to the grid when it's low
You get the bill savings of net metering plus genuine outage protection. The cost sits above on-grid because of the battery and the more sophisticated hybrid inverter, and subsidy eligibility depends on how the system is wired and metered.
If your locality sees frequent or long DHBVN cuts — or you run a home office, medical equipment, or anything that can't tolerate downtime — the extra spend on a hybrid setup usually justifies itself in sheer reliability.
Side-by-Side Comparison
| Feature | On-Grid | Off-Grid | Hybrid | |---------|---------|----------|--------| | Grid connection | Yes | No | Yes | | Battery | No | Yes | Yes | | Net metering | Yes | No | Yes | | Runs during an outage | No | Yes | Yes | | PM Surya Ghar subsidy | Yes | No | Depends | | Relative cost | Lowest | Highest | Medium-High | | Best suited to | Most urban homes | Off-grid plots | Outage-prone areas |
Matching the System to Your Situation
Go on-grid when:
- Your DHBVN supply is fairly dependable (true for most of urban Faridabad and Gurugram)
- You want the lowest upfront cost and the quickest payback
- Claiming the full central subsidy matters to you
- You can live with the rare power cut
Go off-grid when:
- The grid simply doesn't reach your property
- Energy self-sufficiency is the whole point
- Budget isn't the deciding factor
Go hybrid when:
- Power cuts in your area are frequent or long
- You need uninterrupted supply for critical loads
- You're happy to pay more for that peace of mind
