A 7 kW rooftop solar system is a fantastic choice for families with greater energy needs. With this rooftop solar, you can expect to produce approximately 8,000 to 9,000 units of electricity annually. However, this output varies based on the sunlight intensity and geographical position in your area.
A 7 kW system can easily power the following:
- 5-6 ceiling fans
- 5-6 LED bulbs
- 2-3 air conditioners (1.5 tons each) or 1 air conditioner alongside other heavy appliances
- Refrigerator
- Washing machine
- Television
- Kitchen appliances like microwave, mixer, induction cooktop
- Laptops and charging devices
A 7 kW rooftop solar system is ideal for 3-4 BHK homes. Its capacity comfortably supports essential energy needs without straining the system, even during peak usage hours for seamless operation.
Beyond immediate savings, it offers long-term sustainability benefits, making it a smart investment for households looking to reduce their carbon footprint and achieve energy independence.

6 tips for choosing the right 7 kW solar system for your home
1. Select a vendor that conducts a thorough roof survey
Many local solar installers overlook essential metrics, such as checking your roof for spots free from shadows or potential blockages before installing solar panels. This can result in systems that look more like a messy Lego creation than an efficient setup. Ensure your vendor conducts a thorough shadow analysis over a year to identify any objects that might cast shadows on your panels.
They should also consider the available space on your roof and accurately gauge your energy consumption to create the most effective system possible. This careful planning boosts performance and helps sidestep problems like hotspots, inadequate electricity production, and fire risks.
2. Opt for a vendor that provides engineered solar solutions
The right vendor for your solar panel installation will consider your roof’s specific layout and structural characteristics. This ensures that the panels are installed efficiently and safely, providing optimal long-term results for your investment. Look for a vendor that applies engineering expertise to create a customised design tailored to your home’s unique needs.
3. Find the right solar vendor should offer guaranteed savings
Investing in rooftop solar for your home can be a smart financial move but only if you choose the right vendor. According to a study by CEEW and PV Diagnostics, more than half of solar systems underperform in their first year.
To safeguard your investment, look for a vendor that offers guaranteed savings through solar. The vendor should compensate you for any shortfall if the system doesn’t produce the promised energy output.
4. Choose a vendor that offers cyclone-proof solar structures
With India’s increasing vulnerability to cyclones and extreme weather conditions, it is important to have strong and durable solar structures. When choosing a vendor, ensure they provide certified cyclone-resistant structures designed to withstand high wind speeds. This will ensure that your solar system remains secure and operational even during adverse weather conditions.
5. Choose a vendor that prioritises after-sales maintenance services
Like a car or air conditioner, a solar system needs regular maintenance to perform at its best. When choosing a vendor for your rooftop system, look for those offering comprehensive after-sales service to ensure that your solar continues to function efficiently and generate consistent energy for many years to come. This will protect your investment and provide peace of mind.
6. Go with a vendor offering verified financing options
Investing in a solar system can be a big financial decision for many homeowners. But with the help of a reputable vendor, you can access verified financing options approved by trusted financial institutions or third-party verifiers.
These financing solutions make it more manageable to cover the upfront costs of installing solar panels, so you can enjoy the benefits of clean energy without stretching your budget too thin.
Let’s explore financing options for your 7 kW solar system.
7 kW solar system with Solar Loan/EMI (0 investment)
If you have a solid rapport with your bank, you might consider applying for a loan to cover the expenses of your solar setup.
However, if you opt for SolarSquare’s rooftop solar solution, we offer a zero-investment plan that allows you to install the system at virtually no cost upfront, with loan approval possible in under 24 hours.
- Zero Initial Investment: The subsidy you receive covers the initial payment required for your solar system installation, ensuring you won’t have to spend anything out of pocket.
- Easy EMIs: Your monthly instalment payments are structured to align with the savings on your electricity bill.
If your solar system produces more energy than is needed to cover the EMI, you won’t pay anything additional. Solar installations also enable you to earn ₹2 per unit on average for excess electricity sent to the grid. Payment rates and schedules depend on state-specific net metering rules.
- Flexible Payment Terms: We provide a range of EMI options from 6 to 60 months, enabling you to choose a payment plan that suits your budget.

FAQs
Q1. How many solar panels are required for 7 kW?
Ans. To produce 7 kW of power using SolarSquare’s bifacial Monoperc half-cut solar panels, each with a peak capacity of 545 watts, you would need around 13 to 14 panels. The math is simple.
7,000 Watts / 545 Watts per panel = 12.9 panels, which rounds up to 13 panels.
With older technology panels, more modules would be needed to achieve the same capacity.
Q2. How much electricity does a 7 kW solar system generate?
Ans. A 7 kW solar system can generate approximately 8000 to 9,000 units of electricity annually, depending on the amount of sunlight your location receives. This can be enough to cover the energy needs of a medium to large home, particularly for households with higher electricity consumption.
Q3. How many appliances can be powered by a 7 kW rooftop solar system?
Ans. A 7 kW system can easily power the following:
- 5-6 ceiling fans
- 5-6 LED bulbs
- 2-3 air conditioners (1.5 tons each) or 1 air conditioner alongside other heavy appliances
- Refrigerator
- Washing machine
- Television
- Kitchen appliances like microwave, mixer, induction cooktop
- Laptops and charging devices
Q4. How many ACs can run on a 7 kW solar system?
Ans. A 7 kW solar system can power 2-3 air conditioners (1.5 tons each) simultaneously. However, if you are running other heavy appliances like a refrigerator, washing machine, or microwave along with the ACs, it’s best to balance the load accordingly. You could also opt to run just one AC along with the other major appliances to avoid straining the system.
