What is an Off-Grid Solar Plant?

Complete Guide for Homes, Farms & Rural Areas in India

In many parts of India, especially in rural and semi-urban areas, unreliable electricity and frequent power cuts are still a major problem. If you are tired of depending on the government power supply and want complete energy independence, installing an off-grid solar system for home in India could be the ideal solution.

What is an Off-Grid Solar System?

An off-grid solar power plant is a self-sustaining energy system that works without any connection to the electricity grid. It generates power using solar panels and stores it in solar batteries, enabling you to use electricity even at night or during cloudy weather.

It is commonly referred to as a solar system with battery backup. Unlike on-grid solar systems, it does not rely on the power grid, making it perfect for remote homes, farms, and small businesses.

Key Components of an Off-Grid Solar System

• Solar PV Panels – capture sunlight to generate DC electricity
• Solar Inverter (Off-Grid) – converts DC to usable AC electricity
• Battery Bank – stores excess energy for night-time or emergency use
• Solar Charge Controller – regulates voltage and battery charging
• Mounting Structure, Cables & Accessories

Whether you are planning an off-grid solar system for farm irrigation, for your residential home, or a village school, this setup ensures reliable and clean energy without monthly electricity bills.

Difference Between Off-Grid and On-Grid Solar Systems

Let’s understand how off-grid and on-grid solar systems differ and which one is best for your needs:

Feature	Off-Grid Solar	On-Grid Solar
Grid Dependency	No	Yes
Power Backup	Yes, via battery	No
Suitable For	Remote/Rural/Farm Homes	Urban Houses/Factories
Electricity Bills	Zero	Reduced (via Net Metering)
Government Subsidy	Available under PM-KUSUM or MNRE	Available
Installation Cost	Slightly Higher	Lower
Use in Power Outage	Works	Doesn’t work if grid fails

If you’re located in an area with frequent power cuts, or planning a solar solution for a remote village, then going off-grid is the better option.

Best States in India for Off-Grid Solar Systems

An off-grid solar system with battery price becomes more attractive when you consider its long-term independence and savings. Many Indian states are ideal for such systems due to weak grid infrastructure or low electrification.

Top states where Off-Grid Solar Systems are in high demand:

• Uttar Pradesh – especially Bundelkhand and eastern districts
• Jharkhand – tribal zones and mining towns
• Bihar – flood-prone and rural north Bihar
• Chhattisgarh – forest and remote tribal belts
• Assam & Nagaland – northeastern hilly and village areas
• Rajasthan (rural) – desert regions without grid
• Ladakh & Himachal Pradesh – off-grid homes in the Himalayas

These regions are often beyond the reach of electricity boards or suffer frequent power failure, making off-grid solar system for rural home a practical investment.

Off-Grid Solar Plant Cost in India (2025)

The cost of an off-grid solar plant in India varies depending on system size, battery type, and inverter quality. Here’s an updated estimate:

Capacity	Ideal For	Approx Price (INR)
1 kW	Small rural home	₹85,000 – ₹1,10,000
3 kW	2-3 room house or shop	₹2,40,000 – ₹3,00,000
5 kW	Large home or small clinic	₹4,20,000 – ₹5,00,000
10 kW	Office, lodge, or school	₹8,00,000 – ₹10,00,000

The price includes battery backup, which is essential for off-grid systems. Lithium-ion battery solar systems cost more than lead-acid types but offer longer life and better efficiency.

Benefits of an Off-Grid Solar System in India

• Zero Electricity Bill – No need to worry about monthly payments
• Complete Power Backup – Works during blackouts and at night
• Best for Villages and Farmlands – No dependency on electricity board
• PM-KUSUM Subsidy – Available for farmers and institutions
• Eco-Friendly Energy – Reduce carbon footprint and diesel use

With an off-grid solar system subsidy in India, many states are actively promoting rural electrification, especially for farmers under PM-KUSUM Yojana and state solar programs.
