Types of 8 kW Solar Systems in India and Their Prices

The three primary types of solar systems in India are on-grid, off-grid and hybrid. All three have their own specialities. 

An on-grid solar system is the most affordable, as it does not require lead-acid or lithium batteries to store solar energy since it is connected to the grid. It makes an on-grid solar system perfect for urban areas with a reliable grid connection. However, if your area experiences frequent power cuts, a hybrid or off-grid solar system will be better, as these systems have batteries to provide backup power during outages.

Let’s check out the 8 kW solar system cost in India for all three types:

How Many Solar Plates are Required for 8 kW?

If you choose 540-watt solar panels, you will need ~15 of them to make an 8 kW solar system. We’ve used this simple formula to make the calculation: 

Based on this formula, here’s how we ended up with ~15 solar panels:

Is 8 kW Enough to Power a House?

An 8 kW solar system is an extremely powerful photovoltaic device that can generate between 11,200 and 11,600 units of electricity yearly. This much power is more than enough to run large 4-5 BHK homes, and bigger bungalows and villas. 

It can run 3 1.5-ton air conditioners simultaneously while powering other common home appliances such as LED lights, tube lights, TVs, washing machines, fans, coolers, geysers, refrigerators, and even a water pump. 

Here’s a table that enlists the approximate first-year unit generation you can expect from an 8 kW solar system in your city:

*Please note: The generation figures mentioned above are approximate and meant for general reference only. Actual output can vary from these estimates due to multiple factors, including pollution levels in your city, changes in sunlight availability, weather patterns, roof angle, panel orientation, shading from surrounding objects, and dust accumulation. Technical elements, such as solar panel efficiency, inverter performance, wiring quality, and system losses, can also impact generation levels. Even routine maintenance and regional temperature fluctuations can affect the amount of power your system produces over time.

What are the Benefits of Installing an 8 kW Rooftop On-Grid Solar System in India?

Installing an 8 kW on-grid rooftop solar system is extremely beneficial, as it generates free electricity for 25 years using only solar radiation. As a result, it saves tens of lakhs of rupees you would have otherwise spent on electricity bills and offsets thousands of kilograms of carbon dioxide because solar energy is non-polluting.

Let’s check out all the benefits of installing an 8 kW on-grid solar system in your city:

• It’s extremely affordable compared to other PV systems: An on-grid solar system is a worthwhile investment in urban areas where power outages are infrequent and backup isn’t necessary. Since it doesn’t require lead-acid or lithium batteries to store solar energy, it’s much more affordable than off-grid and hybrid solar systems. However, if power outages are frequent and prolonged in your area, you will require a battery backup. In such cases, hybrid and off-grid systems are better.
• It makes the electricity bills near zero: Since the solar system covers all your energy requirements by supplying free solar electricity, your reliance on expensive grid electricity plummets by 90% or more. Many customers eventually receive near-zero bills.
• It’s beneficial for the environment: An 8 kW solar system can offset ~2,10,000 kg of carbon dioxide from the atmosphere over 25 years, as it’s equivalent to planting 314 full-grown trees in any city. 

Why Choose SolarSquare’s 8.10 kW Solar System?

Installing an 8 kW solar system with 540-watt solar panels actually requires 14.81 panels (8,000 ÷ 540). That number is unrealistic because nobody can install a fraction of a panel. It will be either 14 or 15 panels. 

If you go with 14 panels, you’re downgrading the system size to 7.56 kW, which can’t meet all your energy requirements if your annual power consumption is between 11,200 and 11,600 units, or more. The result can be significant for your solar savings, as your reliance on grid electricity with a downgraded system will be higher. This will result in bills higher than they should be and savings lower than expected. 

That’s why SolarSquare launched an 8.10 kW solar system that uses exactly 15 solar panels, each 540 watts (8,000 ÷ 540 = 15), ensuring you receive maximum solar savings and a very high ROI. 

Conclusion

The 8 kW solar panel price in India with subsidy for on-grid rooftop solar panel systems for homes ranges between ~Rs. 3.62 lakh* in Lucknow and ~Rs. 4.47 lakh* in Bangalore. This money is a worthwhile investment because the ROI is unmatched. Whether you invest the same amount in gold, FDs, or mutual funds, they will not be able to match the ROI from solar. For instance, installing an 8 kW solar system in Pune at ~Rs. 3.92 lakh* will save ~Rs. 53.54 lakh* over 25 years. That’s an ROI of ~13.6x!

*Please note: The above-mentioned 8 kW solar panel price in India with subsidy is indicative as of 7th November 2025 for the SolarSquare Blue 6ft variant. The final 8 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. Additionally, when calculating savings, we have considered an annual tariff escalation of 3% and an annual degradation of 1%. The actual final savings from an 8 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.
