Residential Solar System —
Cut Your Electricity Bill by up to 90%
A rooftop solar panel setup designed specifically for homes — independent houses, bungalows, villas, and apartments across India — to generate electricity from sunlight on-site and save big on bills.
What Is a Residential Solar System?
A residential solar system is a rooftop solar panel setup designed specifically for homes — independent houses, bungalows, villas, and apartments across India — to generate electricity from sunlight on-site.
Most homeowners in cities like Delhi, Noida, Gurugram, Mumbai, Pune, and Bangalore choose an on-grid (net-metered) residential solar system, since it's the most affordable rooftop solar option and qualifies for full government subsidy support. A well-sized home solar system reduces dependence on grid electricity, cuts your monthly power bill significantly, and pays back its installation cost within a few years.
Solar Panels
Convert sunlight into DC electricity. Panel quality and efficiency directly affect your generation and savings.
Inverter
Converts DC to AC power, sized to match your panel capacity and home load.
Mounting Structure
A wind-rated frame that holds panels securely to your roof, built to survive storms and heavy rain.
Net Meter
A bi-directional meter installed by your DISCOM that records both imported and exported electricity units.
Wiring & Safety
DC/AC cables, combiner boxes, and protection devices that keep the system running safely.
Earthing Protection
Grounding equipment that protects your home and system from electrical faults and lightning.
How Does a Residential Solar System Work?
A seamless transition from sunshine to massive savings for your household.
1. Solar Generation
Solar cells absorb sunlight and generate DC electricity through the day.
2. Power Conversion
The inverter converts DC power into AC power that your home appliances can safely use.
3. Home Priority
Your household runs on solar power before drawing anything from the grid.
4. Grid Export
Extra units generated are sent to the grid and credited via the net meter.
5. Night Usage
At night or on low-sunlight days, your home draws the shortfall from the grid.
6. Reduced Bill
Your monthly electricity bill reflects only the net units consumed - imports minus exports.
Benefits of Residential Solar Panels for Homes in India
Cut electricity bills by 80-90%
Most homeowners see bills drop to near-zero from day one.
Government subsidy on rooftop solar
Get up to Rs. 78,000 back under PM Surya Ghar Muft Bijli Yojana, with extra state subsidy in Delhi and UP.
Zero-cost EMI options
Subsidy covers your down payment; EMIs align with your existing bill amount.
25-year asset life
Panels keep generating power for decades with minimal upkeep.
Higher property value
A solar-powered home is a strong resale and rental advantage in India's growing real estate market.
Lower carbon footprint
Even a 1 kW rooftop solar system can offset ~26,000 kg of CO2 over 25 years.
Government Subsidy for Homes
Central government subsidy applies to on-grid residential solar systems using DCR panels, for capacities up to 3 kW and above, across all Indian states.
| System Size | Central Subsidy |
|---|---|
| 1 kW | Rs. 30,000 |
| 2 kW | Rs. 60,000 |
| 3 kW & above | Rs. 78,000 (capped) |
Homeowners in Delhi and Uttar Pradesh receive additional state-level solar subsidy on top of the central amount — up to Rs. 30,000 more depending on system size. The subsidy is credited directly to your bank account after net meter installation and system commissioning, through the PM Surya Ghar National Portal.
Residential Solar Panel Price
Rooftop solar panel prices for homes vary by city, DISCOM charges, panel brand, inverter type, and roof height. Here's an indicative price range before subsidy is applied:
| Size | Suitable For | Price (before subsidy) |
|---|---|---|
| 2 kW | 1-2 BHK home | Rs. 1.80L - 2.15L |
| 3 kW | 2-3 BHK home | Rs. 2.10L - 2.50L |
| 4 kW | 3 BHK home, higher usage | Rs. 2.55L - 2.95L |
| 5 kW | 3-4 BHK home | Rs. 3.15L - 3.85L |
| 10 kW | Large home / villa | Rs. 5.80L - 6.50L |
With PM Surya Ghar subsidy applied:Your effective solar panel cost for home can drop by Rs. 60,000 to Rs. 1.08 lakh, depending on your system size and state.
Savings & ROI Over 25 Years
| System Size | Payback Period | 25-Year Savings | Approx ROI |
|---|---|---|---|
| 2 kW | ~4-5 years | ~Rs. 10.74L | ~9x |
| 3 kW | ~4-5 years | ~Rs. 16.11L | ~11.8x |
| 4 kW | ~4 years | ~Rs. 21.48L | ~11.8x |
| 5 kW | ~3-4 years | ~Rs. 33.46L | ~14x |
| 10 kW | ~3-4 years | ~Rs. 66.92L | ~13.6x |
*Calculated assuming ~3% annual tariff escalation and ~1% annual panel degradation. Actual savings depend on your city, sunlight availability, roof orientation, and system maintenance.
How to Choose the Right Size
| Monthly Electricity Bill | Recommended System |
|---|---|
| Rs. 1,500 - 2,500 | 2 kW |
| Rs. 2,500 - 4,000 | 3 kW |

Frequently Asked Questions About Residential Solar in India
How much can I save with residential solar panels?
Most homeowners across Indian cities cut their electricity bills by 80-90%, and savings grow further each year as grid electricity tariffs rise.
How much roof space do I need for solar panels?
As a rule of thumb, 100 sq. ft. of shadow-free rooftop can accommodate about 1 kW of solar panels.
Do I need to pay the full solar panel cost upfront?
No. With PM Surya Ghar subsidy covering part of the cost and 0-cost EMI options available, you can go solar with little to no upfront payment.
Is my roof suitable for rooftop solar panels?
Most roof types work well for residential solar installation, especially south-facing roofs with no shadow-casting obstructions nearby.
How long does home solar installation take in India?
Physical installation is usually completed in about a week; the full process including DISCOM approval takes 4-6 weeks.
What is the lifespan of a residential solar system?
A well-maintained rooftop solar system lasts 25 years or more, continuing to generate clean power throughout its life.
