Overview of Off-Grid Solar System

An off-grid solar system, also known as a standalone solar system, works on the same principle as an on-grid solar system .

Solar PV panels capture sunlight and convert it into electricity. The key difference is that an off-grid solar power system is not connected to the utility grid. Instead, it stores excess electricity in batteries for use during nighttime or power outages.

What is an Off-Grid Solar System?

An off-grid solar system s a standalone set-up that produces and stores electricity without any connection to the public utility grid. How? It stores the power it generates in batteries. It’s a careful set-up of the following components that work in tandem to produce electricity from sunlight:

• Solar panels (modules)
• Mounting structures
• Batteries
• Solar charge controller
• Solar inverter
• Solar accessories

When to Use an Off-Grid Solar Panel System?

Most Indian homes do not require off-grid solar systems, as their power consumption needs are met by on-grid rooftop solar systems, which are much cheaper and easier to maintain.
However, you will need an off-grid solar system in the following situations:

• You live in a remote area with no utility grid
• Your area faces extreme power cuts and the grid is unreliable

However, if you live in an area with a reliable grid connection, the benefits of an on-grid solar system are unbeatable!

What’s the Off-Grid Solar System Price in India in 2025?

The off-grid solar system price in India varies based on factors such as:

• The system capacity
• The type of solar panels
• The type of solar inverter
• Types of batteries (12 volt, 24 volt, or 48 volt)

Before we walk you through the prices based on multiple factors, let’s address the matter of subsidy on an off-grid solar system in India in the section below!

What About Off-Grid Solar System Subsidy?

To clear the air once and for all, the Indian government does not offer a subsidy on off-grid solar systems under the PM Surya Ghar Muft Bijli Yojana. You need to install an on-grid rooftop solar system to receive the financial assistance the government offers in the form of a subsidy.
That said, let’s check out the off-grid solar system price based on system capacity:

Please note: Maven Green Energy does not install off-grid solar systems. The off-grid solar panel prices listed above are standard market estimates.

Advantages and Disadvantages of Off-Grid Solar System

Here’s a clear breakdown of the benefits of installing off-grid solar power systems in India:

• Power Where You Need It: An off-grid solar system is the only option in rural areas where there is no grid
• Zero-emission Energy Source: Off-grid solar power is clean and green. Not only does it power homes where there’s no grid, but it also ensures that no pollution is being caused in lieu of generating electricity.

ROI (return on investment) in the case of off-grid solar systems takes more time than an on-grid system of the same capacity. Why? Well, because batteries are expensive.

• Usually, the off-grid solar system price breaks even in about 6-7 years.
• In the case of an on-grid solar system, the price breaks even in 3-4 years.

Here are a few other limitations of installing off-grid solar in India:

• Repeated investment in batteries since they have to be replaced after their life is over
• Higher maintenance cost since they have to be replaced after their life is over
• There’s no subsidy offered to bring down the cost of installing off-grid solar systems
