*Please note: The above-mentioned 6 kW solar panel price in India with subsidy for on-grid solar systems is indicative as of 6th November 2025 for the SolarSquare Blue 6ft variant. The final 6 kW on-grid solar system price in India depends on your DISCOM charges, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change. Additionally, when calculating savings, we have considered an annual tariff escalation of 3% and an annual degradation of 1%. The actual final savings from a 6 kW on-grid solar system depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

Let’s check out all the major benefits of installing an on-grid 6 kW solar system in India in detail:

• It’s the most affordable among all solar systems: Since it doesn’t require batteries to store solar energy, it costs less than an off-grid and hybrid solar system. So, if you happen to live in cities where power cuts are not an issue, an on-grid solar system will be perfect for you.
• It offers a very high ROI: The solar system generates free solar electricity for 25 years. As a result, all the money you used to spend on electricity bills will now be saved. Over 25 years, the savings will be in tens of lakhs of rupees, offering an ROI that no other investment can match.
• It can make your electricity bills near zero: The solar system tackles all your energy requirements, reducing your bills by 90% or more. 
• It can tackle air pollution: Installing a 6 kW solar system in India is equivalent to planting 235 full-grown trees. Do you know how much carbon these many trees absorb from the environment over 25 years? That’s a whopping ~1,55,000 kg of carbon dioxide. A 6 kW solar system will offset this much carbon by preventing it from being released into the atmosphere in the first place, as it uses non-polluting solar radiation to generate electricity. 

Why Choose SolarSquare’s 6.48 kW Solar System?

Ever tried figuring out how many 540 W panels you’d need for a 6 kW solar system? Let’s do the math.

6,000 W divided by 540 W equals 11.11 panels. That’s not possible in real life because you can’t install a fraction of a panel. You either round down to 11 panels or round up to 12.

If you stop at 11 panels, your system ends up being just 5.94 kW, which is smaller than you planned. You’ll lose out on potential energy generation, especially during peak sunlight hours, which will eventually reduce the savings as your reliance on grid electricity will be higher than it should be, even after going solar.

That’s why SolarSquare introduced its 6.48 kW solar system that uses 12 full solar panels. With our 6.48 kW solar system that uses the latest TOPCon or mono-PERC solar panels, you will achieve higher energy output, resulting in greater savings and a higher ROI over your system’s 25-year lifespan. 

Conclusion

The 6 kW solar panel price in India with subsidy for on-grid solar systems in 2025 drops from ~Rs. 3.60 lakh* in Delhi and ~Rs. 4.25 lakh* in Bangalore to ~Rs. 2.52 lakh* in Delhi and ~Rs. 3.47 lakh* in Bangalore. Spending a few lakhs on a solar system will save you from the sorrow of paying hefty bills tomorrow, which rise by 3-6% every year in India.

*Please note: The above-mentioned 6 kW on-grid solar system price in India is indicative as of 6th November 2025 for the SolarSquare Blue 6ft variant. The final 6 kW solar plate price depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change.
