10kW Solar System Price in India (2026)
| System Type | Gross Cost | Subsidy | Net Cost |
|---|
| On-grid | ₹5,22,000 – ₹6,38,000 | ₹78,000 | ₹4,44,000 – ₹5,60,000 |
| Hybrid (with battery) | ₹6,48,000 – ₹7,92,000 | ₹78,000 | ₹5,70,000 – ₹7,14,000 |
| Off-grid | ₹7,65,000 – ₹9,35,000 | ₹0 | ₹7,65,000 – ₹9,35,000 |
State top-ups in Delhi, Uttar Pradesh and Assam reduce the net cost further; the calculator above applies them
when you pick your state. For a full quote-style breakdown, use the

What Can a 10kW Solar System Run?
A 10kW system generates about 38.4 units a day (1152 units a month) in a typical Indian city. That
comfortably powers a very large home, duplex or small office: three to four air conditioners, an EV charger and all appliances. It suits monthly bills of ₹7,500 to ₹11,000 and needs a correspondingly large roof.
10kW Solar System Quick Specs
- Panels: 19 × 550W modules (fewer with 600 – 620W panels)
- Roof area: 800 – 1000 sq. ft. of shadow-free space
- Generation: ~38.4 units/day, ~1152 units/month, ~14,016 units/year
- Inverter: 10 kW string or hybrid inverter
- Payback: typically 3 – 6 years after subsidy, then 20+ years of low-cost power
Is 10kW the Right Size for You?
A 10kW system belongs on villas, duplexes and small offices billing ₹7,500 to ₹11,000 a month (900 to 1,300 units), with at least 800 sq. ft. of clean roof. At this size the project behaves commercially: three-phase supply is effectively mandatory, structure design deserves an engineer's signature, and the ₹78,000 subsidy is a rounding line rather than the deal-maker. Wrong-fit signs: consumption under 700 units, or a residential net-metering policy in your state that caps systems below 10kW.
Worked Example: A 10kW System in Visakhapatnam
A Visakhapatnam home installs 10kW on-grid at about ₹5,80,000 gross. The capped ₹78,000 subsidy barely dents it, leaving a net
cost near ₹5,02,000. At the city's 4.8 peak sun hours the system produces
about 38.4 units a day (1152 a month), trimming up to ₹7,776
off the monthly bill at the local ₹7.5 tariff. Run the calculator above with your own city to see
how these numbers shift with sun hours and state subsidies.
From 10kW Estimate to Installation
- Confirm the size against your usage with the
solar system size calculator; the right kW comes from your
units, not from a page you happened to land on.
- Check the connection. Three-phase supply and a sanctioned load of 10kW or more are prerequisites nearly everywhere; some states also cap residential net metering at 10kW, making this the practical ceiling for homes.
- Collect three 10kW quotes and compare them line by line against the
cost calculator's gross range; quotes far below it are cutting
something you will miss later.
- Apply on the national portal before installing, use a registered vendor, and expect the
subsidy by bank transfer a few weeks after inspection.
10kW Mistakes to Avoid
- Assuming volume discounts scale forever. Per-kW pricing improves modestly at 10kW, but structure engineering and three-phase gear claw some of it back; compare quotes per kW, not per project.
- Ignoring the state's net-metering ceiling. Where residential caps are 10kW, an 11kW dream needs commercial treatment; confirm the cap before design.
- Under-engineering the structure. Nineteen panels catch serious wind; insist on wind-load calculations for elevated or high-rise installations.
- Forgetting who watches the meter. At ₹8,000 a month of expected savings, a monitoring app and a monthly generation check are not optional; a silent string failure at this size loses real money weekly.
How These 10kW Numbers Are Calculated
Daily units = 10 kW × Peak sun hours × 0.8
Net cost = Gross cost − Subsidy
Monthly saving ≈ Monthly units × Your tariff × 0.9
Assumptions
- Cost: on-grid ₹58,000/kW, hybrid ₹72,000/kW, off-grid ₹85,000/kW, ±10%
- Generation: your city's peak sun hours × 0.8 performance ratio
- Saving: assumes ~90% of generation offsets billed units at your tariff
