Types of 3 kW Solar Systems and Their Prices
There are three most common kinds of solar systems one can install at home:
- On-grid (grid-connected) solar system
- Off-grid (stand-alone) solar system
- Hybrid solar system
Before we walk you through the three types, here’s a price comparison between them:
| Type of Solar System | 3 kW Solar Plant Price* (Approx.) |
| 3 kW on-grid solar system price in India with subsidy | Rs. 1,02,000 to Rs. 1,57,000 |
| 3 kW off-grid solar system price in India | Rs. 2,30,000 onwards |
| 3 kW hybrid solar system price in India | Rs. 4,50,000 onwards |
*Please Note: SolarSquare does not install off-grid or hybrid solar systems. The 3 kW solar panel prices listed above are standard market estimates.
Let’s find out why there’s so much price variation between the three types.
#1. On-grid Solar System
An on-grid solar system ties into the utility network via a bidirectional meter that records your energy deposits and withdrawals.
Read more about how an on-grid solar system works.
But why is an on-grid solar system the cheapest of the three options? The other two types require a battery, whereas an on-grid system doesn’t.
#2. Off-grid Solar System
An off-grid solar system is not connected to the grid. It runs entirely on its own power.
The reason why an off-grid system is expensive (besides the fact that it’s not eligible for a subsidy under the government’s DBT scheme) is the cost of batteries.
Read more about how an off-grid solar system works.
#3. Hybrid Solar System
A hybrid solar system is hands down the most advanced (and also the costliest) type. It’s connected to both the main grid and batteries.
Shouldn’t you opt for a hybrid solar system instead of an on-grid solar system?
Honestly, you don’t need it if you live in an urban area with a reliable grid. An on-grid solar system that costs less than half the cost of a hybrid system requires far less maintenance (since it doesn’t have batteries).

3 kW Solar Panel Price With a Solar Loan
Solar loans let you finance your rooftop solar with ease. Banks and NBFCs (non-banking financial companies) offer them. So, if you have a good relationship with your bank, you can request a loan to fund your solar installation.
However, if you choose SolarSquare’s rooftop solar:
- We offer a zero-investment plan where your Government subsidy covers your down payment, and monthly solar savings cover your EMIs for certain loan tenure.
- The loan approval takes 1-2 days!
- You can choose a tenure between 3-60 months, depending on your budget.
Is 3 kW the Right Capacity for Your Home?
For many Indian households, a 3 kW rooftop solar system is the perfect fit. However, installing a system of this capacity largely depends on two key factors:
- Your household’s energy consumption
- The amount of shadow-free rooftop space available
As energy consumption varies widely from one household to another, choosing the right solar rooftop system for your home based on these factors can be a game-changer.
Let’s now give you a breakdown of typical appliances that a 3 kW solar system can support and the power each one consumes:
| Appliances a 3 kW Solar System Powers | Power Consumed by Appliances |
| 1 Refrigerator | 150-400 watts |
| 1 Geyer | 1,500 watts |
| 1 Washing Machine | 300-500 watts |
| 1 TV | 60-120 watts |
| 3-4 LED Bulbs | 4-25 watt/ bulb |
| 1-2 LED Tube Lights | 8-36 watt/ tube light |
| 4-5 Fans | 75 watts each |
| Common Kitchen Appliances | 1,000 watts |
| Total Power Consumed | Approximately, 3,417 watts (3.41 kW) |
Does this sound like your home’s power consumption? Congratulations! SolarSquare’s 3.24 kW solar system is the ideal choice for you.
Not sure if your home consumes this much power?
- Review your electricity bills from last year
- Calculate the average number of units consumed in a year
- Divide the yearly units consumed at your home by the number of units produced by a 1 kW solar system (1,400* units/year).
*On average, a 1kW solar system produces 1,400-1,450 units per year.
