Off-Grid Solar System —
Power Anywhere, No Grid Needed
A completely standalone power setup that generates its own electricity and stores it in batteries. Enjoy power anytime — day, night, or during a total grid outage.
What Is an Off-Grid Solar System?
An off-grid solar system is a completely standalone power setup that is not connected to the public electricity grid at all. It generates its own electricity through solar panels and stores it in batteries, so power is available anytime — day, night, or during a total grid outage.
Unlike an on-grid system, there's no net meter and no reliance on the utility company. Everything you use is generated and stored by your own system.
Solar Panels
Generate DC electricity from sunlight; the primary energy source for the whole system.
Charge Controller
Regulates voltage and current from panels to the battery, preventing overcharging and damage.
Battery Bank
Stores energy for use at night or on low-sunlight days. Battery capacity decides your backup duration.
Off-Grid Inverter
Converts stored DC battery power into AC power for home appliances, with no grid dependency.
Mounting Structure
Holds panels securely in place, built to withstand wind, rain, and weather.
Wiring & Earthing
Cables, combiner boxes, and earthing kits that keep the system safe and efficient.
Off-Grid Solar: Step by Step
True energy independence, powered by the sun and stored for your convenience.
1. Solar Generation
Solar panels absorb sunlight and generate DC electricity through the day.
2. Charge Regulation
The charge controller regulates how much power goes to the battery to prevent overcharging.
3. Power Storage
Surplus solar power is stored in the battery bank for later use.
4. DC to AC Conversion
The inverter converts DC power from the battery into AC power for appliances.
5. Home Usage
Appliances draw power directly from the battery — day or night.
6. Total Independence
The system runs fully independent of the grid at every stage.
Benefits of an Off-Grid Solar System
The perfect solution for remote areas and those seeking total energy independence.
Works without any grid connection
Ideal for remote areas, farms, and locations with no grid access.
Full power backup
Battery bank ensures uninterrupted power, even during long outages.
No electricity bill
Since there's no grid connection, there's no monthly bill at all.
Energy security
Complete control over your own power supply, unaffected by grid failures.
Scalable
Add more panels or batteries later as your power needs grow.
Ideal for critical loads
Great for essential equipment that can't afford any downtime.
Off-Grid vs On-Grid Solar System
| Feature | Off-Grid | On-Grid |
|---|---|---|
| Connected to grid | No | Yes |
| Needs battery | Yes | No |
| Government subsidy | Not applicable | Yes |
| Works during power cut | Yes | No |
| Cost | Higher | Lower |
| Best for | Remote/unreliable grid areas | Areas with stable grid supply |
Battery Backup Needs
How much battery backup do you need?
| Daily Power Need | Recommended Capacity |
|---|---|
| Lights, fans, TV (essential loads) | 2-3 kWh |
| + Fridge, water pump | 4-6 kWh |
| + AC / heavy appliances | 8-10 kWh and above |
Price Guide (Indicative)
Battery type and capacity are the biggest price drivers — depends on brand & chemistry.
| Size | Suitable For | Price (approx.) |
|---|---|---|
| 1 kW | Small home, essential loads only | Rs. 1.1L - 1.4L |
| 2 kW | Small home / shop | Rs. 2.1L - 2.6L |
| 3 kW | Home / farmhouse | Rs. 2.9L - 3.6L |
| 5 kW | Larger home / remote office | Rs. 4.6L - 5.5L |
| 10 kW | Commercial / remote facility | Rs. 8.5L - 10L |
Frequently Asked Questions
Does an off-grid system need a grid connection at all?
No. It works completely independent of the electricity grid, generating and storing its own power.
Is government subsidy available on off-grid systems?
No. The PM Surya Ghar subsidy applies only to on-grid (net-metered) systems.
How long does the battery last?
Lithium batteries typically last 8-10 years; tubular batteries around 4-5 years, depending on usage.
Can I run an AC on an off-grid system?
Yes, but you'll need a larger battery bank and inverter capacity sized for that load.
What happens on cloudy days?
Your battery bank supplies power from its stored charge, so the system keeps running as long as it's sized correctly.
Total Independence from the Grid
An off-grid solar system represents the pinnacle of energy independence. By generating and storing 100% of your power on-site, you completely eliminate electricity bills and disconnect entirely from the utility grid.
This is the ideal solution for properties in remote areas, agricultural farms, and rural locations where grid access is either non-existent or highly unreliable. With high-efficiency solar panels and robust battery banks (such as advanced Lithium-ion), your home or business can operate smoothly around the clock, immune to blackouts or fluctuating electricity tariffs.
While an off-grid setup doesn't qualify for the PM Surya Ghar subsidy and requires a larger upfront investment in batteries, the unmatched autonomy and long-term security it provides make it an invaluable asset for those who demand self-sufficient, green energy anywhere in India.
