You need to register on pmsuryaghar.gov.in, apply for rooftop solar, select an MNRE-approved vendor, complete installation, get net metering approval, and upload documents. The subsidy is credited directly to your bank account within 30 to 90 days.
7. Which is better: on-grid or off-grid for homes?
On-grid systems are ideal for most homes due to lower cost and subsidy eligibility. Off-grid systems are better suited for areas with frequent power cuts where grid reliability is low.
8. How much roof space is required for a 5kW system?
A 5kW solar system generally requires about 300 to 350 square feet of shadow-free roof area. The exact requirement depends on panel efficiency and layout design.
9. Can I get a loan for a 5kW solar system?
Yes, many Indian banks offer solar loans with interest rates typically ranging from 8% to 12%. Some financing options also allow subsidy benefits to be adjusted against the loan amount.
10. What is the difference between Mono PERC and TOPCon panels?
Mono PERC panels are more affordable and widely used, offering good efficiency. TOPCon (N-type) panels are more efficient, degrade more slowly, and perform better in low-light conditions, making them suitable for premium installations.
Conclusion
A 5kW system is certainly one of the most practical and reliable choices for Indian homes looking to reduce electricity bills and to gain long-term energy independence.
The common and most chosen on-grid 5kW solar panel price in India ranges anywhere between ₹2.3 lakh and ₹2.7 lakh, and with the PM Surya Ghar subsidy of up to ₹78,000, the effective investment price becomes significantly more affordable.
From a financial perspective, the system offers a payback period of around 3 to 5 years. After that, homeowners can enjoy nearly 19 to 21 years of low-cost or almost free electricity.
On average, a 5kW setup generates 20 to 25 units per day, leading to monthly savings of ₹2,500 to ₹6,000 depending on usage and location.
Other than savings, the environmental impact of choosing a 5kW solar system is equally strong. It can offset approximately 5 to 6 tonnes of CO2 every year, making it a valuable step toward sustainable living and reducing dependence on grid electricity.
