Off-Grid Solar System
An off-grid system operates fully independently of the utility grid and runs entirely on a dedicated battery bank. It is the ideal solution for areas with no grid access or a highly unstable supply, such as remote farmhouses, isolated job sites, and agricultural pumps.

Quick answer
What Is an Off-Grid Solar System?
An off-grid system runs only on solar panels and batteries, with no connection to the utility grid.
Solar panels charge a battery bank through the day, and an inverter powers your appliances day and night. It suits remote farmhouses, job sites, and agricultural pumps where the grid is absent or unreliable.

How It Works
How Off-Grid Solar Works
- 01
Panels Generate Power
Solar panels produce DC electricity through the day.
- 02
Charge Controller
An MPPT controller gets the most from the panels and charges the batteries safely.
- 03
Battery Bank Stores It
Excess power is stored for use at night and during cloudy weather.
- 04
Inverter Powers Your Loads
Battery power is converted to AC for your appliances.
Standalone Power
Power Where the Grid Cannot Reach
An off-grid system runs your site entirely on solar and batteries, engineered for the days of autonomy your site requires.
- The battery bank is sized for cloudy days.
- The structure is built strong for remote sites.
- Our team provides maintenance support.
Battery Sizing
Getting the Battery Right
The battery is usually the biggest cost in an off-grid system, so careful sizing matters.
Days of Autonomy
Days of autonomy is the number of days an off-grid system can run on batteries alone, and we size it for your site.
Cloudy-Day Output
On heavily overcast days, energy generation may drop to a small fraction of its peak capacity.
Day and Night Load
We split your load between daytime use and battery use at night.
Pros and Limits
Is Off-Grid Right for You?
Advantages
- You get power where there is no grid.
- Power cuts do not affect your supply.
- Off-grid solar is clean, quiet, and emission-free.
Keep in Mind
- Off-grid has the highest upfront cost of the three types.
- Off-grid is not eligible for the PM Surya Ghar subsidy.
- Batteries need periodic replacement.
- Where the grid is reliable, on-grid is cheaper.

On-Grid vs Hybrid vs Off-Grid
| Feature | On-grid | Hybrid | Off-grid |
|---|---|---|---|
| Grid connection | Yes, with net meter | Yes, with net meter | No |
| Battery | No | Yes | Yes |
| Power during cuts | No (shuts down for safety) | Yes, for selected loads | Yes |
| PM Surya Ghar subsidy | Yes (for homes) | Possible (panels only) | No |
| Upfront cost | Lowest | Higher | Highest |
| Best for | Reliable grid and maximum savings | Areas with frequent power cuts | Remote areas with weak or no grid |
Subsidy depends on eligibility and DISCOM approval. Battery cost is not covered by the subsidy.
FAQ
Frequently Asked Questions
Find clear answers on subsidy, batteries, air conditioners, and whether off-grid suits your home.
Is there a subsidy for off-grid solar?
No. PM Surya Ghar applies to grid-connected rooftop systems only.
Which batteries do you use?
Off-grid systems typically use lithium (LFP) or lead-acid batteries. We recommend the type after studying your load and budget.
Can an off-grid system run an air conditioner?
Yes, if the panels and battery are sized for it. This needs a larger system.
Is off-grid right for a home in the city?
Usually not. Where the grid is available, on-grid or hybrid gives better value.
