• Large 2BHK homes
• 3BHK apartments
• Villas and independent houses
• Homes with air conditioners
• Households consuming 500–700 units per month

How Much Electricity Does a 5kW Solar System Generate?

Electricity generation depends on location, sunlight availability, roof orientation, and system efficiency.On average, a 5kW rooftop solar system can generate around 7,000–8,500 units annually.

Location	Average Daily Generation	Monthly Generation
Hyderabad	20–24 units	600–720 units
Vijayawada	19–23 units	570–690 units
Bengaluru	18–22 units	540–660 units
Chennai	20–24 units	600–720 units

Mounting Structure	₹20,000 – ₹40,000
Electrical Components	₹15,000 – ₹30,000
Installation &Labor	₹20,000 – ₹50,000
Total Cost	₹2.5 Lakh – ₹3.5 Lakh

Premium TOPCon and bifacial solar panels generally cost more but offer higher efficiency and long-term energy generation.

Government Subsidy for 5kW Solar Systems

The PM Surya Ghar scheme has made rooftop solar more affordable for homeowners across India.

Benefits include:

• Reduced upfront investment
• Faster return on investment
• Lower electricity bills
• Improved solar adoption

The Government of India continues to promote rooftop solar adoption through the PM Surya Ghar Muft Yojana, making the 5kW solar system price in India more affordable for homeowners. The subsidy amount depends on the approved system capacity, location, and compliance with government guidelines.

To qualify for subsidy benefits, homeowners must complete the required documentation, install the system through authorized vendors, and obtain net metering approval from their local DISCOM. Before proceeding with installation, it is important to verify the latest subsidy guidelines and eligibility requirements.

For homeowners evaluating the solar panel cost in India 2026, government incentives can significantly reduce the upfront investment and improve the overall return on investment.

One of the biggest reasons homeowners choose solar is long-term electricity bill reduction.

Example Savings Calculation

Assume:

• Monthly generation: 650 units
• Electricity tariff: ₹8 per unit

Monthly savings:

650 × ₹8 = ₹5,200

Annual savings:

₹5,200 × 12 = ₹62,400

Over 25 years, savings can exceed ₹15 lakh depending on electricity tariff inflation.

5kW Solar System ROI and Payback Period

A rooftop solar system should be viewed as a long-term investment.

Typical payback period:

4–6 years

Expected system life:

25+ years

After the payback period, the electricity generated is essentially free, resulting in significant savings for the remaining lifespan of the system.

Factors affecting ROI:

• Electricity tariff rates
• Solar panel efficiency
• Roof shading conditions
• Net metering benefits
• Maintenance quality

5kW vs 3kW vs 10kW Solar System

Parameter	3kW	5kW	10kW
Suitable For	Small Homes	3BHK Homes &Villas	Large Villas &Commercial
Monthly Units	360–450	600–720	1,200–1,500
Approx Cost	Lower	Moderate	Higher
Savings Potential	Medium	High	Very High

For most Indian homeowners, a 5kW solar system provides the best balance between investment and savings.

Who Should Install a 5kW Solar System?

A 5kW rooftop solar system is ideal if:

• Your electricity bill exceeds ₹3,000 per month
• You consume 500–700 units monthly
• You own a suitable rooftop
• You plan to stay in the property long term
• You want to reduce dependence on rising electricity tariffs

Conclusion
