3kW Solar System Price in India 2025: Claim ₹78,000 Government Subsidy

Solar energy has become one of the most reliable and sustainable power solutions in India. With increasing electricity bills and growing environmental concerns, homeowners and small businesses are now turning to solar panel systems to reduce their dependency on grid electricity. Among the different solar capacities available, the 3kW solar system stands out as a popular choice for medium-sized homes.

In this detailed guide, we’ll cover everything you need to know about a 3kW solar panel system — including price in India, government subsidies, specifications, benefits, and more. Whether you are planning to install solar for your home or a small commercial setup, this guide will help you make an informed decision.

What is a 3kW Solar Panel System?

A 3kW solar panel system is a power setup that can generate around 12 to 15 units of electricity per day, depending on sunlight availability. It is ideal for medium-sized homes with 2 to 3 air conditioners, several fans, lights, a refrigerator, washing machine, and other common appliances.

This system can power most household needs, especially when combined with a solar inverter and battery backup (for off-grid setups). A 3kW system typically consists of 8 to 10 solar panels, depending on the wattage of each panel (generally 370W to 450W).

Average Power Generation of a 3kW Solar System

This output may vary based on several factors such as:

• Location (solar radiation levels)
• Tilt angle and direction of panels
• Type of solar panels (Monocrystalline or Polycrystalline)
• Dust and shading on panels
  
  

Types of 3kW Solar Systems in India

There are three main types of solar systems available in the Indian market. The right choice depends on whether you want to stay connected to the grid or be fully independent.

a) On-Grid 3kW Solar System

An on-grid solar system is directly connected to the electricity grid. It allows you to use solar energy during the day and draw electricity from the grid at night. Excess energy produced by the solar panels is exported to the grid, for which you receive credits through the net metering system.

Ideal For: Homes with stable grid supply and high daytime electricity consumption.

Key Features:

• Works only when the grid is available
• No batteries required
• Eligible for government subsidy
• Easy to maintain
  

b) Off-Grid 3kW Solar System

An off-grid solar system works independently of the electricity grid. It comes with battery storage, which stores excess solar energy for use during night or power cuts.

Ideal For: Rural areas or locations with frequent power cuts.

Key Features:

• Operates without a grid connection
• Comes with batteries (increases cost)
• Provides 24×7 power supply
• No subsidy available for off-grid systems
  
  

c) Hybrid 3kW Solar System

A hybrid system combines the best of both worlds — it’s connected to the grid and also includes batteries. It allows you to store energy and export surplus power to the grid.

Ideal For: Areas with moderate grid supply and need for backup power.

Key Features:

• Battery plus grid connection
• High flexibility and efficiency
• Slightly higher investment cost
• Not always eligible for subsidy

3kW Solar Panel System Price in India (2025)

The 3 kilowatt solar panel price in India depends on the type of system, brand, and installation location. Prices can vary between ₹1.5 lakh to ₹3 lakh, depending on whether it’s on-grid, off-grid, or hybrid.

Here’s a price breakdown:

Note: Prices include panels, inverter, structure, wiring, and installation. GST and other local charges may apply depending on the installer.

So, when calculating your 3 kw solar plant price, always check for:

• System type
• Brand of panels and inverter
• Installation location and structure design
• Subsidy availability

Government Subsidy on 3kW Solar System

Under the PM Surya Ghar Muft Bijli Yojana (2024–25), the government of India is offering huge subsidies to encourage residential solar adoption. The subsidy rates are based on system capacity.

Central Financial Assistance (CFA) under PM Surya Ghar Yojana

That means, for a 3kW solar system, homeowners can get ₹78,000 subsidy directly transferred to their bank account after successful installation and inspection.

Eligibility Criteria

• Must be a residential rooftop installation.
• The consumer must have an active electricity connection.
• The system must be installed by an MNRE-approved vendor (like Bluebird Solar and other empaneled companies).
• The user must apply through the official National Portal for Rooftop Solar (https://solarrooftop.gov.in).

Specifications of a 3kW Solar System

Here’s a typical specification sheet for a 3kW solar system setup:

Benefits of Installing a 3kW Solar System

Investing in a 3 kw solar system comes with a wide range of financial and environmental benefits. Let’s look at the key ones:

a) Major Reduction in Electricity Bills

A 3kW solar setup can save up to ₹3,000–₹4,000 per month on electricity bills, depending on your consumption and local tariff rates.

b) Quick Return on Investment (ROI)

With subsidies and bill savings, most homeowners recover their investment in 4–5 years, after which electricity is practically free for the next 20 years.

c) Low Maintenance

Solar panels require minimal maintenance. Cleaning the panels once or twice a month ensures maximum efficiency.

d) Eco-Friendly Energy Source

A 3kW solar system reduces approximately 3–4 tons of CO₂ emissions every year, contributing to a cleaner environment.

e) Energy Independence

Having solar power reduces your reliance on grid electricity, protecting you from rising power tariffs.

f) Increases Property Value

Homes with solar installations are considered more valuable and sustainable — an attractive feature for future buyers.

Area Requirement for a 3kW Solar System

A 3kW solar system generally needs 250–300 sq. ft. of unobstructed rooftop space. South-facing roofs are ideal in India, as they receive maximum sunlight throughout the day.

You can also install solar panels on carports, tin sheds, or elevated structures if space is limited.

Brands and Components You Can Choose

When selecting components for your 3 kw solar panels, ensure that all parts are MNRE and BIS approved.
Here are some popular options:

• Solar Panels: Bluebird Solar, Waaree, Tata Power Solar, Adani Solar, Vikram Solar
• Inverters: Growatt, Luminous, Delta, Sungrow, Fimer
• Batteries (for off-grid): Exide, Amaron, Okaya

Always choose Tier-1 quality panels and reliable installers for long-term performance.

Maintenance Tips for 3kW Solar Systems

• Clean panels with soft water and cloth every 15–20 days.
• Inspect for any dust, bird droppings, or shading.
• Check inverter readings regularly.
• Schedule an annual inspection by your solar provider.
• Avoid using harsh chemicals during cleaning.

Proper care ensures optimal performance and maximizes lifespan.

Cost Savings and Payback Calculation

Let’s take an example:

After the payback period, the electricity generated is practically free, making solar one of the best long-term investments.
