Hybrid Solar System Price & Calculator

A hybrid solar system cuts your bill like an on-grid system and keeps your essentials running in a power cut. Check the hybrid solar system price in India after subsidy, and the battery and hybrid inverter size your backup actually needs.

A hybrid solar system costs about ₹72,000 per kW installed (±10%) in our estimates, about ₹14,000 per kW more than on-grid. It still gets the PM Surya Ghar subsidy, so a 3 kW hybrid system costs about ₹1,16,400 – ₹1,59,600 after subsidy.

The battery decides the real price: backing up 800 W of essentials for 4 hours needs about 4.4 kWh of lithium (roughly ₹80,000 of battery). Use the calculator below for your own backup.

Hybrid Solar System Price in India (2026)

Indicative installed prices for hybrid home systems at our standard ₹72,000 per kW rate (±10%), with the central PM Surya Ghar subsidy:

2 kW₹1,29,600 – ₹1,58,400₹60,000₹69,600 – ₹98,400
3 kW₹1,94,400 – ₹2,37,600₹78,000₹1,16,400 – ₹1,59,600

5 kW₹3,24,000 – ₹3,96,000₹78,000₹2,46,000 – ₹3,18,000
10 kW₹6,48,000 – ₹7,92,000₹78,000₹5,70,000 – ₹7,14,000

Hybrid quotes vary most in the battery. A quote with a small battery looks cheap but backs up little; compare the battery kWh in every quote with what the calculator above says you need. As a guide, each kWh of lithium storage costs about ₹18,000 and each kWh of lead-acid about ₹9,000. Delhi, Uttar Pradesh and Assam add state top-ups to the subsidy.

How a Hybrid Solar System Works

Panels feed a hybrid inverter, which does three jobs: it powers your home, charges the battery, and exports any surplus to the grid through a net meter, just like an on-grid system. When the grid fails, it disconnects from the grid for safety and keeps your backup loads running from the battery, and most hybrid inverters keep using solar power during the cut as well. When the grid returns, it switches back automatically.

Hybrid vs On-Grid vs Off-Grid Solar

Batteries add backup, not savings, so a hybrid system pays back more slowly than on-grid. See the off grid solar system calculation guide if you have no grid at all.

Sizing the Battery and the Hybrid Inverter

A hybrid system has two separate sizes to get right, and the solar kW decides neither of them:

  • Battery: backup watts × hours ÷ 1,000 ÷ 0.85, then divided by the usable depth of discharge (0.85 for lithium, 0.5 for lead-acid).
  • Hybrid inverter, backup side (VA): the watts that must run together ÷ 0.8 power factor, plus 20% headroom.
  • Hybrid inverter, solar side (kW): close to your panel kW; the array can be up to about 1.2 times the inverter rating.
Backup needLithium batteryLead-acid batteryBackup inverter
500 W for 4 hours (fans, lights, Wi-Fi)2.8 kWh4.7 kWh850 VA

Lithium lasts 3,000 to 6,000 cycles (10+ years of daily use) against 800 to 1,500 cycles for lead-acid, so it usually costs less per usable kWh over its life. Size your exact battery with the solar battery calculator and the inverter with the inverter size calculator.

Is a Hybrid System Worth It for You?

  • Yes if power cuts are frequent or long enough to disrupt work, study or medical equipment at home.
  • Probably not if your grid fails only a few times a year; on-grid gives the fastest payback, and a small inverter battery can cover rare cuts.
  • Keep the backup list short. Fans, lights, fridge and Wi-Fi need about 800 W; adding an AC to the backup roughly triples the battery.

Hybrid Buying Mistakes

  • Comparing quotes by price alone. Two "3kW hybrid" quotes can differ by several kWh of battery; compare the kWh.
  • Backing up the AC and geyser. Heating and cooling drain batteries fast; keep them on the grid.
  • Choosing hybrid for savings. The battery adds cost and small losses; choose hybrid for backup.
  • Forgetting net metering. A hybrid system still needs net metering and a registered vendor to get the subsidy.

How the Hybrid Estimate Is Built

Hybrid price = System kW × ₹72,000 (±10%) − Central and state subsidy
Battery kWh = Backup W × Hours ÷ 1,000 ÷ 0.85 ÷ Depth of discharge
Backup inverter VA = Backup W ÷ 0.8 × 1.2, rounded up to a standard size

Hybrid assumptions

  • Hybrid rate: ₹72,000 per kW installed, ±10%; subsidy as for on-grid systems
  • Battery: 85% inverter efficiency; depth of discharge 85% lithium, 50% lead-acid; about ₹18,000/kWh lithium and ₹9,000/kWh lead-acid
  • Generation: your city's peak sun hours × 0.8 performance ratio

Hybrid Solar FAQs

What is the price of a hybrid solar system in India?+
About ₹72,000 per kW installed (±10%) in our estimates, before subsidy. A 3 kW hybrid system costs about ₹1,94,400 to ₹2,37,600, or ₹1,16,400 to ₹1,59,600 after the ₹78,000 PM Surya Ghar subsidy. The battery size in the quote changes the price most.
What is the price of a 5kW hybrid solar system?+
About ₹3,24,000 to ₹3,96,000 before subsidy, or ₹2,46,000 to ₹3,18,000 after the ₹78,000 subsidy. Check how many kWh of battery the quote includes against your backup needs.
What is a hybrid solar inverter?+
An inverter that combines a solar inverter and a battery inverter. It runs your home from solar, charges the battery, exports surplus to the grid, and switches to battery backup in a power cut. It has two ratings to check: the solar input in kW and the backup output in VA.
Does a hybrid solar system work during a power cut?+
Yes. When the grid fails, the hybrid inverter disconnects from the grid and runs your backup loads from the battery, and most models keep using solar power during the cut too. An on-grid system, by contrast, shuts down in a power cut.
Do hybrid solar systems get the PM Surya Ghar subsidy?+
Yes. A hybrid system is grid-connected, so it gets the same ₹30,000, ₹60,000 or ₹78,000 based on its solar capacity, through a registered vendor with net metering. Off-grid systems do not qualify.
How many batteries does a hybrid solar system need?+
It depends on your backup load and hours, not on the panel size. Backing up 800 W of essentials for 4 hours needs about 4.4 kWh of lithium, for example a 48 V 100 Ah battery, or about 7.5 kWh of lead-acid.
Can I convert my on-grid system to hybrid later?+
Yes. The usual route is to replace the on-grid inverter with a hybrid inverter and add a battery, or to add a separate battery inverter alongside the existing one. Your panels stay the same, so starting on-grid and adding backup later is a reasonable plan.
Is a hybrid system better than on-grid?+
Only if you need backup. Hybrid costs about ₹14,000 more per kW and the battery adds cost without adding savings, so on-grid pays back faster. Choose hybrid when power cuts genuinely disrupt your home.
How long do hybrid solar batteries last?+
Lithium (LiFePO4) batteries last about 3,000 to 6,000 cycles, which is 10 years or more of daily use. Lead-acid batteries last about 800 to 1,500 cycles, typically 3 to 5 years.
