Off-grid/Standalone Solar Electric Systems
Off-Grid Solar Electric Systems in India: Standalone Solar Power Where the Grid Doesn't Reach
An off-grid (standalone) solar system generates and stores its own electricity, using solar panels, a battery bank and an inverter, with no connection to the power grid. It is the right choice for remote locations, farms and rural areas where grid power is unavailable or unreliable. Ashirwad Solar, a solar panel company in India based in Pune, designs, supplies and installs these systems.
Off-grid systems are one of the most popular types of solar installation. They are designed to supplement or replace the conventional mains supply.
They are mainly used where there is no other source of power, such as remote locations and rural areas where it is difficult to get power from grid extensions.

How an Off-Grid Solar System Works
From Sunlight to Stored Power
Generally, an off-grid system uses solar power to charge batteries. The stored charge is then supplied to your loads whenever you need it, day or night.
DC Loads and AC Appliances
The battery power can directly run DC loads, such as DC lamps. Or it can drive an inverter that converts DC power to AC, so you can run appliances such as pumps, lighting equipment and refrigerators.
Small and Simple by Design
This method is followed for any standalone system, whether it is a pocket calculator or a complete off-grid home. Standalone systems are comparatively small and simple.
Main Parts of an Off-Grid System
| Part | What it does |
|---|---|
| Solar panels | Turn sunlight into DC electricity.. |
| Charge controller | Protects the batteries by controlling how they charge. |
| Battery bank | Stores energy for night time and cloudy days. |
| Inverter | Converts DC battery power to AC for normal appliances. |
| Structure, cables and protection | Hold the panels safely and connect the system. |
Who Needs an Off-Grid Solar System?
- Remote and rural locations: Where getting power from a grid extension is difficult.
- Farms and farmhouses: For lighting, appliances and irrigation away from the grid.
- Homes with frequent power cuts: A standalone system keeps essentials running.
- Small shops and outdoor sites: Lighting and basic equipment without a grid connection.
- Any standalone use: From a small device to a complete off-grid home.
Off-Grid vs Grid-Connected Solar
| Point | Off-grid | Grid-connected |
|---|---|---|
| Grid connection | None | Connected to the grid |
| Batteries | Required | Usually not needed |
| Works during grid power cuts | Yes | Usually not, unless a hybrid setup is used |
| Best for | Remote sites and areas with no or poor grid | Homes and businesses with reliable grid power |
If you already have dependable grid power, a grid-connected system is usually the lower-cost way to save on your bill. Ask us which suits you.
What You Can Power With an Off-Grid System
Water Pumps for Farms and Homes
Pumps are one of the most common off-grid loads. Our solar pumps are built to run on solar power for irrigation and water supply where the grid is weak or far away.
Lighting
Off-grid power suits outdoor and remote lighting. Look at our solar street lights and portable solar lanterns for areas without grid supply.
Homes and Farmhouses
A rooftop solar system with a battery bank can run lights, fans, a refrigerator and a pump in a farmhouse or a home with frequent outages.
Larger Remote Projects
For bigger sites that need careful design, a solar EPC company in India like us can plan, supply, build and maintain the whole plant under one contract.
How to Size an Off-Grid Solar System
- List your appliances: Note each one and how many hours you use it daily.
- Work out daily energy: This decides the number of panels you need.
- Decide your backup: How many cloudy or night hours must the batteries cover?
- Check your space and sunlight: Shade-free area is needed for the panels.
- Plan for growth: If you may add loads later, size the system with room to expand.

Frequently Asked Questions
What is an off-grid solar system?
An off-grid (standalone) solar system makes and stores its own power without using the electricity grid. Solar panels charge batteries, and the batteries supply your lights, pumps, refrigerators and other appliances whenever you need them.
How does an off-grid solar system work?
Solar panels generate DC power that charges the batteries. The battery power either runs DC loads such as DC lamps directly, or goes through an inverter that converts DC to AC so you can run AC appliances like pumps, lights and refrigerators.
What is the difference between off-grid and on-grid solar?
An off-grid system works on its own with batteries and has no connection to the grid. An on-grid system is connected to the grid, usually has no batteries, and can lower your bill through net metering. Off-grid suits places with no or poor grid supply.
Do I need batteries in an off-grid system?
Yes. Batteries store the solar energy so you can use power at night and on cloudy days. The battery size depends on how much power you use and how long you need backup.
Where are off-grid solar systems used?
They are mainly used in remote locations and rural areas where it is difficult to get power from grid extensions, such as farms, farmhouses, villages and remote sites. They also work for any standalone use, from a small device to a complete off-grid home.
Can an off-grid system run a water pump or refrigerator?
Yes. With the right panel, battery and inverter size, an off-grid system can run pumps, lighting, refrigerators and other appliances. We size the system to your load.
How do I decide the right size for an off-grid system?
List every appliance you want to run and the hours you use each one. From this we work out the daily energy need, then size the panels, battery bank and inverter. Share your list and we will suggest the right system.
Do you supply and install off-grid solar systems?
Yes. Ashirwad Solar supplies the equipment and handles design, installation, commissioning and after-sales support. Call +91 99224 26936 or use the form on this page for a free quote.
