That’s exactly why rooftop solar is gaining real momentum across Delhi-NCR. And right now, with the central government’s PM Surya Ghar Muft Bijli Yojana offering direct subsidies, there has rarely been a better time to act. For homes and small businesses with higher electricity consumption, the 10 kW solar panel price in Delhi — especially after subsidy — works out to a genuinely compelling investment.
Let’s break down everything you need to know before signing a single cheque.
What Is a 10 kW Solar System?
10 kW solar panel price in Delhi refers to a rooftop installation with a combined panel capacity of 10,000 watts (10 kW). Under Delhi’s solar irradiance conditions — roughly 5 to 5.5 peak sun hours per day — such a system typically generates:
- 40–50 units (kWh) of electricity per day
- 1,200–1,500 units per month
- 14,000–18,000 units per year
That’s enough to comfortably run a 4–5 BHK home with multiple ACs, a high-end kitchen, heavy appliances, and still have surplus units to export back to the grid.
Roof area required: You’ll need approximately 600–700 sq. ft. of shadow-free rooftop space. Flat RCC roofs work best, though inclined surfaces can also be used with appropriate mounting frames.
Who should consider it? The 10 kilowatt solar system cost makes most sense for:
- Large residential homes with monthly bills above ₹6,000–₹8,000
- Small offices, clinics, or retail shops with daytime electricity loads
- Guesthouses or farmhouses with consistent high consumption
10 kW Solar Panel Price in Delhi in 2026
Solar pricing varies based on the system type you choose, the brand of panels and inverters, and the quality of installation. Here’s a realistic overview of the market in 2026:
| System Type | Estimated Price Range (Before Subsidy) |
| On-Grid 10 kW | ₹5.5 lakh – ₹7.5 lakh |
| Hybrid 10 kW | ₹7.5 lakh – ₹10.5 lakh |
| Off-Grid 10 kW | ₹9 lakh – ₹14 lakh (with batteries) |
The solar panel 10kW price range exists because of several variables. Tier-1 panels from brands like Waaree, Adani Solar, or Vikram Solar command a premium over generic imports but come with stronger performance guarantees and better degradation curves. Similarly, a high-end string inverter from SMA or Fronius will cost more than a domestic alternative — but reliability over a 25-year system life often justifies the difference.
Installation complexity also plays a role. A flat, accessible rooftop in an apartment building costs less to set up than a sloped roof requiring custom mounting or difficult cable routing.
The price of 10 kW solar system listed above covers panels, inverters, mounting structure, DC/AC cabling, protection devices, and basic installation. Net metering charges and DISCOM approvals are typically billed separately.
Government Subsidy Available for 10 kW Solar Systems
The PM Surya Ghar Muft Bijli Yojana, launched in February 2024, is the most significant residential solar subsidy programme India has seen. It replaced the earlier MNRE rooftop subsidy and offers direct benefit transfer (DBT) to homeowners’ bank accounts after successful installation.
How the Subsidy Works
The subsidy is calculated on benchmark costs set by MNRE, not on what you actually pay. The current structure (as of 2026) for residential systems is:
| System Capacity | Central Subsidy Amount |
| Up to 2 kW | ₹30,000 per kW |
| 2 kW to 3 kW | ₹18,000 per kW (for the 3rd kW) |
| Above 3 kW | Capped at ₹78,000 total |
This means for a 10 kW system, the maximum central subsidy is ₹78,000 regardless of system size beyond 3 kW. Delhi residents may also explore any additional state-level benefits through BSES Rajdhani, BSES Yamuna, or Tata Power Delhi.
Eligibility Criteria
- Indian citizen with a residential electricity connection
- Applying through the official PM Surya Ghar portal (pmsuryaghar.gov.in)
- Installation only through a registered DISCOM-empanelled vendor
- System capacity not exceeding sanctioned load or DISCOM limit
Practical Example
Suppose you install a 10 kW on-grid system at ₹6.5 lakh.
- Central subsidy: ₹78,000
- Net cost after subsidy: ₹5,72,000
That’s a meaningful saving — and some DISCOMs in Delhi also offer concessional net metering fees to further reduce your overall outlay.
Important: The subsidy is credited after inspection and grid connection by your DISCOM. Budget for the full amount upfront and treat the subsidy as a reimbursement that typically arrives within 30–60 days post-inspection.
Cost Breakdown of a 10 kW Solar System
Understanding where your money goes helps you evaluate vendor quotes more critically. Here’s a typical component-wise breakdown for a 10 kW on-grid installation in Delhi:
| Component | Approximate Cost Range |
| Solar Panels (10 kW) | ₹2,50,000 – ₹3,50,000 |
| Solar Inverter (10 kW) | ₹60,000 – ₹1,20,000 |
| Mounting Structure | ₹40,000 – ₹70,000 |
| DC & AC Cabling | ₹20,000 – ₹40,000 |
| Protection Devices | ₹10,000 – ₹20,000 |
| Installation Labour | ₹20,000 – ₹40,000 |
| Net Metering Charges | ₹5,000 – ₹15,000 |
| Total (approx.) | ₹4,05,000 – ₹6,55,000 |
The 10 kW solar inverter price depends significantly on the type. A standard on-grid string inverter for 10 kW typically runs between ₹60,000–₹90,000, while a hybrid inverter with battery-readiness can push past ₹1,20,000–₹1,80,000.
The cost to install 10kW solar system also factors in the height and accessibility of your roof, whether three-phase wiring is already in place, and how far the panel array is from the distribution board. A straightforward installation on an open rooftop will always be cheaper than one requiring long conduit runs or structural reinforcement.
10 kW Solar System with Battery Price
For many Delhi homeowners, the real pain point isn’t high bills — it’s power cuts. If your area experiences load shedding or you want backup security, adding battery storage to your solar system makes sense.
A 10kW solar system with battery price will depend on battery type and capacity:
Lithium-Ion Batteries (Recommended)
- Higher upfront cost (₹80,000–₹1,50,000 for a 10 kWh bank)
- 3,000–5,000 charge cycles vs lead-acid’s 500–800
- Lighter, smaller, lower maintenance
- Better depth of discharge (80–90%)
Lead-Acid Batteries (Budget Option)
- More affordable (₹40,000–₹80,000 for comparable storage)
- Shorter lifespan, higher maintenance
- Suitable if budget is constrained and backup needs are occasional
For a home wanting 4–6 hours of backup during an outage (covering lights, fans, one AC), a 20 kWh lithium-ion battery bank is a reasonable target, adding roughly ₹1.5 lakh–₹3 lakh to your total system cost.
10kW Hybrid Solar System Cost
A hybrid solar system combines the best of on-grid and off-grid worlds: it stays connected to the grid (so you can export and earn credits) but also supports battery storage for backup during outages.
The 10kW hybrid inverter price in 2026 ranges from ₹90,000 to ₹1,80,000, depending on brand and features. The 10kW hybrid solar inverter price from reputable brands like Growatt, Solis, or Luminous typically sits around ₹1,20,000–₹1,50,000 for a good-quality unit.
Total 10 kW hybrid system cost (with battery): ₹8 lakh – ₹12 lakh
Who should choose hybrid?
- Homeowners who want both grid export benefits and power backup
- Areas with 2–6 hours of daily outages
- Businesses that cannot afford downtime (clinics, data setups, home offices)
The additional cost over a basic on-grid setup is worth it if power reliability is a serious concern for you.
10kW Off-Grid Solar System Price
An off-grid system operates entirely independently of the electricity grid. It’s less common in a city like Delhi where grid connectivity is stable, but there are valid use cases — farmhouses on the outskirts, properties without grid access, or those who simply want full energy independence.
The 10kW off-grid solar system price is the highest of the three configurations because it requires a larger battery bank to cover consumption during nights and cloudy days.
Typical components and cost:
| Component | Cost Range |
| Solar Panels (10–12 kW) | ₹2,80,000 – ₹3,80,000 |
| Off-Grid Inverter | ₹80,000 – ₹1,50,000 |
| Battery Bank (30–40 kWh) | ₹2,50,000 – ₹4,50,000 |
| Mounting + Wiring | ₹60,000 – ₹1,00,000 |
| Total | ₹6,70,000 – ₹10,80,000 |
One major limitation: off-grid systems are not eligible for net metering or the PM Surya Ghar subsidy, which only applies to grid-connected residential systems. Keep this in mind before choosing.
Monthly Savings and Return on Investment
Let’s put numbers to the financial case. Assume a Delhi household currently paying ₹8,000 per month on electricity (approximately 800–1,000 units at Delhi’s tiered tariff rates).
A 10 kW on-grid system generating 1,300 units/month would cover their entire consumption and export the surplus to the grid for credits.
Savings estimate:
| Metric | Value |
| Monthly bill eliminated | ₹8,000 |
| Annual savings | ₹96,000 |
| Net system cost (after subsidy) | ₹5,72,000 |
| Simple payback period | ~6 years |
| 25-year savings (at 5% tariff escalation) | ₹35–45 lakh |
A payback period of 5–7 years on a system warranted for 25 years is an excellent financial outcome by any standard. After payback, you’re essentially generating electricity for free.
Factors That Affect 10 kW Solar System Cost in Delhi
No two solar installations are identical. Here are the variables that directly influence what you’ll pay:
Panel Technology: Monocrystalline panels are more efficient and compact but cost more than polycrystalline. Bifacial panels, which absorb light from both sides, are increasingly popular for flat roofs.
Roof Type and Condition: A clean, flat RCC roof requires minimal extra mounting work. Older roofs may need reinforcement; sloped roofs need angled frames.
Inverter Quality: Inverter reliability determines uptime over 25 years. Cutting corners here often means expensive repairs mid-life.
Battery Requirement: Adding storage significantly increases upfront cost. Be realistic about your actual backup needs rather than oversizing.
Installation Complexity: Multiple floors, cramped staircases, distance from the main panel, and three-phase vs single-phase connections all affect labour costs.
Net Metering Approvals: Delhi DISCOMs process net metering applications at different speeds. Empanelled vendors familiar with BSES/TPDDL processes can reduce delays.
Brand and Warranty: A 25-year panel performance warranty from a Tier-1 manufacturer has real financial value compared to a cheaper panel with a 10-year warranty.
Is a 10 kW Solar System Worth It in Delhi?
Straight answer: yes — for most high-consumption households and small businesses in Delhi, a 10 kW system delivers strong financial returns, genuine energy independence, and a meaningful reduction in carbon footprint.
The combination of Delhi’s high solar irradiance, rising grid tariffs, direct government subsidy under PM Surya Ghar Yojana, and net metering that credits your surplus generation makes this one of the better investment categories available to homeowners today.
That said, do your homework. Get at least three quotes from DISCOM-empanelled vendors. Verify their past installations. Check the product datasheets for the panels and inverters being offered. And read the subsidy application process carefully so you’re not caught off guard by timelines.
Solar is a 25-year commitment. The right installer and the right products matter enormously.

Conclusion
The 10 kW solar panel price in Delhi in 2026 ranges from approximately ₹5.5 lakh to ₹7.5 lakh for an on-grid system before subsidy, and closer to ₹4.7–6.7 lakh after availing the ₹78,000 central subsidy under PM Surya Ghar Muft Bijli Yojana. Hybrid and off-grid configurations cost more, with batteries being the primary driver.
With annual savings of ₹80,000–₹1,20,000 possible for high-consumption homes, payback periods of 5–7 years are realistic — leaving over 18 years of essentially free electricity. The environmental benefit of displacing around 12–15 tonnes of CO₂ annually is a bonus worth mentioning.
If you’re a Delhi homeowner with a monthly bill consistently above ₹5,000–₹6,000, now is a genuinely good time to go solar. Subsidies are available, technology has matured, and the financial math works strongly in your favour.
Frequently Asked Questions
What is the cost of a 10 kW solar system?
In Delhi’s current market, a 10 kW on-grid solar system costs between ₹5.5 lakh and ₹7.5 lakh before subsidy. After the PM Surya Ghar central subsidy of ₹78,000, the net cost comes down to approximately ₹4.7 lakh to ₹6.7 lakh. Hybrid systems with battery backup will range from ₹8 lakh to ₹12 lakh depending on battery capacity and inverter brand. The exact figure depends on panel brand, inverter type, roof structure, and the installer you choose.
How many batteries are required for a 10kW solar system?
It depends entirely on your backup requirement. For 4–6 hours of backup covering essential loads (fans, lights, refrigerator, one AC), a 20 kWh battery bank is a practical starting point. In lithium-ion terms, that typically means 4–5 batteries of 4–5 kWh each. If you only need 2–3 hours of lights and fans backup, a 10 kWh bank may suffice. There’s no single formula — the right sizing depends on your consumption pattern during an outage.
Can I run my AC all day with solar?
Yes, but with some nuance. A 10 kW solar system generating 40–50 units per day can comfortably run 2–3 split ACs of 1.5 ton each during daylight hours (roughly 6 AM to 6 PM) alongside other household loads. At night, solar generation stops, so you’ll draw from batteries (if installed) or the grid. With an on-grid system and no batteries, AC usage after sunset will be billed at grid rates. Net metering helps offset nighttime consumption with daytime credits.
Is PM Surya Ghar a loan or a subsidy?
PM Surya Ghar Muft Bijli Yojana is a direct government subsidy, not a loan — meaning you don’t repay it. The subsidy amount (up to ₹78,000 for systems above 3 kW) is transferred directly to your bank account after installation and DISCOM inspection. Separately, several banks including SBI, Bank of Baroda, and Canara Bank offer dedicated solar loans at concessional interest rates for those who need financing for the remaining cost. These loans must be repaid and are distinct from the subsidy itself.
