What are the Types of 3 kW Solar Systems and Their Prices in Bangalore?

The three types of solar energy systems in India are on-grid, off-grid, and hybrid photovoltaic systems. On-grid solar systems are better than off-grid and hybrid systems because they’re cheaper and do not require a lithium battery bank to store solar energy. Any excess power generated by the panels during the day is sent to the grid in on-grid systems.

Wondering what the cost difference between these systems is? Here’s a sample table that explores the estimated 3 kW solar panel price in Bangalore for all three solar PV systems:

What Are the Benefits of 3 kW On-Grid Rooftop Solar Systems in Bangalore?

Choosing a 3 kW on-grid solar system makes you eligible to receive a government subsidy under the PM Surya Ghar scheme, making solar panel installation in Bangalore cheaper. Furthermore, since they generate free electricity for 25 years, on-grid solar systems can reduce reliance on expensive grid electricity. 

Let’s check out all the benefits of installing 3 kW on-grid solar systems in detail:

• They make installing solar affordable: Since 3 kW on-grid systems are the cheapest of the three solar system types and the government offers a subsidy of Rs. 78,000 for installing them, they’ve made solar affordable for everyone.
• They reduce bills by 90% or more: Since you no longer rely on expensive grid electricity, your bills get reduced by 90% or more. Many homeowners in Bangalore receive zero bills after they go solar. 
• They have a quick payback period: You can recover the initial investment made on solar panel installation in Bangalore within 3 to 5 years with a subsidy. After that, the system will continue producing free electricity for at least 25 years.
• They make the air breathable and reduce your carbon footprint: A 3 kW solar system offsets 77,616 kg of carbon dioxide from the atmosphere over 25 years, which is equal to the carbon dioxide absorbed by 118 full-grown trees. So, they’re as good as planting 118 trees.

Why Choose SolarSquare’s 3.24 kW and 3.78 kW Solar Systems in Bangalore?

SolarSquare is one of the best solar companies in Bangalore, offering customers the opportunity to install 3.24 kW and 3.78 kW solar systems instead of the standard 3 kW systems. Wondering why this matters so much? Let’s tell you something nobody usually does.

When you calculate the number of high-efficiency solar panels, such as 540-watt bifacial solar panels, used to build a 3 kW solar system, you’ll realize it’s not a whole number. It will come out to be exactly 5.55. Since nobody can install half a panel, you either install 5 panels or 6 panels. 

Now, if you go with just 5 panels, you’re downsizing your system. It won’t be able to meet all your energy needs. Hence, SolarSquare uses 6 full panels to build a 3.24 kW solar system that will be able to cater to all your energy requirements. Plus, if your energy requirements are higher, you can choose our 3.78 kW solar system, made from 7 full panels.

Here’s a simple table that compares the panels needed to build a standard 3 kW system vs our advanced 3.24 kW and 3.78 kW systems:

Conclusion

A 3 kW solar panel price in Bangalore with subsidy reduces from ~Rs. 2.25 lakh* to ~Rs. 1.47 lakh*, as the government offers homeowners a relaxation of Rs. 78,000 on 3 kW PV systems under the PM Surya Ghar Muft Bijli Yojana.
