Off-Grid Solar System
Solar panels with a battery and no bijli line. For places with no power or very poor power.
What is an off-grid solar system?
An off-grid system is not connected to the bijli line. Panels charge the battery in the day. The battery runs your home day and night.
We plan its size from how much power you use each day and how many cloudy days you want covered. So it needs more planning than an on-grid system.
- No bijli line needed
- Battery gives power at night and in clouds
- No net metering
- Usually no PM Surya Ghar subsidy
How it works
No grid needed: the battery supplies your home day and night.
- Panels make power. Sunlight makes DC power in the panels.
- Charge controller. It fills the battery safely and stops overcharging.
- Battery stores power. You use it at night and when it is cloudy.
- Inverter gives AC. It changes battery power into AC for your things.
- Optional generator. Some places add a generator for long cloudy days.
What is in the system
Solar panels
Sized to charge the battery and run daytime use.
Battery
Lithium (LiFePO4) or tubular lead-acid. It is the biggest part of the system.
Inverter and charge controller
MPPT controller and a pure sine wave inverter.
Mounting stand
Strong steel stand for your place, with higher options.
Earthing and safety
Lightning and surge protection, fuses and proper earthing.
Good things
- Works where there is no bijli line
- Not affected by power cuts
- No bijli bill
- Good for pumps, farms and far-off homes
Things to know
- Batteries add a lot of cost and need changing after some years
- It needs careful planning for your use and backup days
- Usually no PM Surya Ghar subsidy, because that is for grid-connected roofs
- Extra power cannot be sent to the line
Which battery to choose
Lithium (LiFePO4)
Lasts longer and needs little care. Costs more at the start.
Tubular lead-acid
Costs less at the start. Needs water top-ups, more space and earlier replacement.
What size?
Add up the units you use in a day and multiply by the backup days you want. We do this at the site visit.
About subsidy
The PM Surya Ghar subsidy is for rooftop solar connected to the bijli line. So a fully off-grid system usually does not get it. If you have a bijli connection, on-grid or hybrid may suit you better. We will tell you honestly.
Who it is good for
Far-off homes and farms
Steady power where the line does not reach.
Flood or cut-prone places
Your own power when the line fails.
Solar pumps and farm use
Daytime pumping and small farm machines.
Mobile towers, CCTV and small posts
Steady power for small, constant loads.
Compare the three systems
| On-Grid | Hybrid | Off-Grid | |
|---|---|---|---|
| Uses the bijli line | Yes | Yes | No |
| Has a battery | No | Yes | Yes |
| Works when power goes | No (stops for safety) | Yes, on battery | Yes, on battery |
| PM Surya Ghar subsidy | Yes | Ask us | Usually no |
| Net metering | Yes | Yes | No |
Other systems: On-Grid Solar | Hybrid Solar
Common questions about off-grid solar
I have a bijli connection. Can I still go off-grid?
You can, but on-grid or hybrid usually costs less and can get the subsidy. We will advise after seeing your place.
How many backup days should I plan for?
Usually one to two days for cloudy weather. More days need a bigger battery. We decide this with you.
Can I get subsidy for off-grid?
Usually not under PM Surya Ghar. For farms, ask us about other schemes like solar pumps.
How long do batteries last?
It depends on the type, use and heat. Lithium usually lasts longer than lead-acid. We explain the warranty of each.
Can I add panels or battery later?
Often yes, if the inverter is chosen for it. Tell us your plan at the start.
