5kW Solar System Price in India (2026) with Subsidy and Benefits
Last updated at : Aug 13, 2026
A 5kW solar system is the go-to choice for medium-to-large homes that run air conditioners, multiple appliances and have monthly bills in the ₹5,000–₹8,000 range. It produces enough power to cut your electricity bill by 70–90% while still fitting on a normal rooftop. Here is the full 2026 cost and savings breakdown.
5kW Solar System Price in 2026
| System Type | Approx. Cost | After ₹78,000 Subsidy |
|---|---|---|
| On-grid 5kW | ₹2.5–3.5 lakh | ₹1.8–2.7 lakh |
| Hybrid 5kW (with battery) | ₹3.5–5 lakh | Varies with battery size |
On-grid systems are cheaper and most popular because they use net metering to send surplus power back to the grid. Hybrid systems add batteries for backup during power cuts, which raises the cost.
Subsidy on a 5kW System
The PM Surya Ghar residential subsidy is capped at ₹78,000, which is the maximum any home receives. That cap applies to a 5kW system too, bringing an on-grid setup down to roughly ₹1.8–2.7 lakh net. It is one of the biggest reasons rooftop solar has become so affordable for Indian families in 2026.
Generation and Savings
A 5kW system in India typically produces:
- Around 20 units per day
- About 600 units per month
That delivers:
- Monthly savings of roughly ₹4,000–₹6,000
- Annual savings of about ₹50,000–₹80,000
- An electricity bill cut of 70–90%
For most homes in this bracket, a 5kW system covers nearly the entire monthly consumption.
Roof Space and Payback
- Roof space needed: around 400–500 sq. ft. of shadow-free area
- Payback period: about 3–4 years
- System lifespan: 25+ years
After the payback window, you essentially enjoy two decades of low-cost electricity, with only routine cleaning and an eventual inverter replacement to plan for.
On-Grid vs Hybrid: Which to Choose
- Pick on-grid if your area has dependable power. It is cheaper, pays back faster and earns net-metering credits.
- Pick hybrid if you face regular outages and need backup for essential loads.
A 5kW system is one of the most common residential solar sizes we install, precisely because it balances cost, savings and coverage so well. If you would prefer not to pay the full amount upfront, solar loans let you fund the system over EMIs that the monthly savings help offset.
Is 5kW Right for You?
Choose a 5kW system if:
- Your monthly bill is around ₹5,000–₹8,000
- You run an AC and several appliances
- You have at least 400–500 sq. ft. of usable roof
If your bill is lower, a 3kW system may be enough; if higher, consider going larger.
