What is a hybrid solar system?
A hybrid system is an on-grid rooftop solar plant with a battery added. One hybrid inverter manages three sources, solar, battery and the BESCOM grid, and decides every second where your power comes from.
On-grid vs hybrid vs off-grid solar
All three use the same panels. What changes is the battery, and what happens when BESCOM supply fails.
| On-grid | Hybrid | Off-grid | |
|---|---|---|---|
| Works during a power cut | No, shuts down for safety | Yes, on backup circuits | Yes |
| Battery | None | Lithium, from 5.1 kWh | Large battery bank |
| Net metering (sell surplus) | Yes | Yes | No |
| PM Surya Ghar subsidy (homes) | Up to ₹78,000 | Up to ₹78,000 on the panels | Not eligible |
| Cost | Lowest | On-grid + battery and hybrid inverter | Highest per unit used |
| Best for | Homes with reliable supply | Homes that need backup and want lower bills | Sites with no grid connection |
Subsidy applies to residential connections with DCR panels and is calculated on the solar panel capacity only; the battery is not subsidised.

Includes TOPCon DCR panels, hybrid inverter, lithium (LFP) battery, standard mounting structure, DC and AC cables, DCDB and ACDB, earthing, lightning arrester, net meter, BESCOM paperwork, delivery and installation. Elevated structures, extra batteries and civil work are quoted separately. Shops, offices and other non-residential buildings pay the price before subsidy. 10 kW and larger systems are priced after a load study. Solar units assume about 1,440 units per kWp a year in Bengaluru; your roof and shading decide the real figure.
How long will the battery run your home?
Enter what you want running during a power cut. The calculator assumes everything you select is on at the same time, which is the worst case.
Usable energy assumes 90% depth of discharge and about 92% inverter efficiency. Solar extends backup during daytime cuts. Fridges, pumps and ACs cycle on and off, so real backup is usually longer than shown.
Is hybrid solar worth it for your home?
A battery adds cost. It earns its place only if power cuts actually hurt you.
Choose hybrid if
- Cuts disrupt work or study: work from home, online classes, a home office or clinic
- Someone at home depends on power: elderly parents, medical equipment, a newborn
- Your area sees frequent or long cuts, or voltage drops during the monsoon
- You already run, or plan to buy, an inverter UPS or generator. A hybrid replaces it with free solar charging
On-grid is enough if
- Cuts are rare and short where you live
- Your main goal is the lowest possible bill for the money spent
- Your current UPS inverter is fine and you are happy to keep it
- Budget is tight. You can choose a hybrid-ready inverter now and add a battery later

What's inside an Eltron hybrid system
Every quote names the make and model of each part, so you can compare like for like.
- Solar panels: TOPCon DCR modules, 550–625 Wp, from Waaree, Saatvik, Adani, Loom or Novasys
- Hybrid inverter: Deye, Power One or Feston, single- or three-phase to match your connection
- Battery: lithium iron phosphate (LFP) modules of 5.1 kWh each, stackable as your needs grow
- Protection: DCDB and ACDB, lightning arrester and earthing pits
- Cabling: Polycab or equivalent DC and AC cables with MC4 connectors
- Backup wiring: your chosen circuits moved to the inverter's backup output
- Monitoring: phone app showing solar, battery, home use and grid export live
- Paperwork: PM Surya Ghar registration, BESCOM net-meter application and commissioning
Warranties and service
Panels: 15-year product and 30-year performance warranty.
Hybrid inverter: 5-year manufacturer warranty.
Lithium battery: 5-year manufacturer warranty.
Eltron: 5 years of free maintenance: health checks, online monitoring, and free replacement of faulty parts within warranty. Panel cleaning and civil work are not included.
Why lithium (LFP), not lead-acid
No water top-ups, no acid fumes, about 90% of the capacity is usable every night, and a 5.1 kWh module fits on a wall. Lead-acid tubular batteries cost less upfront but give less usable energy and wear out sooner with daily solar cycling.
Hybrid solar subsidy and net metering in Karnataka
Subsidy on the solar part
Homes get the PM Surya Ghar subsidy on panel capacity: ₹30,000 per kW for the first 2 kW and ₹18,000 for the third, up to ₹78,000. The battery and its share of the inverter are not subsidised.
Same net metering as on-grid
A hybrid system connects to BESCOM through a bi-directional net meter. Daytime surplus is exported and credited, so you are not forced to store everything in the battery.
Conditions to qualify
A residential electricity connection in your name, DCR panels, registration on the national portal before installation, and a registered vendor. Eltron handles the registration and the claim. Full subsidy guide

Hybrid solar FAQs
Does a hybrid solar system work during a power cut?
Yes. When BESCOM supply fails, the hybrid inverter disconnects from the grid for line safety and runs your backup circuits from the battery and from solar, if the sun is up. The switchover is automatic and usually takes a fraction of a second. A standard on-grid system shuts down completely during a cut.
What is the price of a 3 kW hybrid solar system in Bangalore?
An Eltron 3 kW hybrid system with 3.3 kWp of TOPCon DCR panels and a 5.1 kWh lithium battery costs about ₹3.64 lakh including GST and installation. For a home that qualifies for the PM Surya Ghar subsidy, the net cost is about ₹2.86 lakh.
What does a 5 kW hybrid solar system cost?
A 5 kW single-phase hybrid system with 5.2 kWp of panels and a 5.1 kWh lithium battery costs about ₹4.90 lakh including GST, or ₹4.12 lakh after the ₹78,000 subsidy. The three-phase version costs about ₹5.14 lakh, or ₹4.36 lakh after subsidy. Extra batteries are priced in your quote.
Is the PM Surya Ghar subsidy available for hybrid solar?
Yes, for homes. The subsidy is calculated on the solar panel capacity only, at ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, up to ₹78,000. The battery is not subsidised. You need a residential connection, DCR panels and registration on the national portal before installation.
How many hours of backup will I get?
It depends on what you run. A 5.1 kWh lithium battery gives roughly 8 hours for 500 W of essentials such as lights, fans, Wi-Fi, a TV and the fridge. Two batteries double that. Use the backup calculator on this page with your own appliances.
Can I add a battery to my existing on-grid solar system?
Often, yes. Some hybrid inverters can be added alongside an existing on-grid inverter, and in other cases we replace the on-grid inverter with a hybrid one and keep your panels. We check your current inverter and wiring at the survey before recommending either route.
Can a hybrid solar system run an air conditioner?
Yes, if the inverter and battery are sized for it. A 1.5-ton AC draws about 1.5 kW while the compressor runs, so a single 5.1 kWh battery would run it for roughly 2–3 hours on its own. Most homes back up essentials and use the AC only when solar or the grid is available.
Does net metering work with a hybrid system?
Yes. A hybrid system connects to BESCOM through a bi-directional net meter, exactly like an on-grid system. Surplus solar is exported and credited on your bill, and Eltron handles the net-meter application.
What warranty do I get on a hybrid system?
Panels carry a 15-year product and 30-year performance warranty. The hybrid inverter and the lithium battery each carry a 5-year manufacturer warranty. Eltron adds 5 years of free maintenance, which covers health checks, monitoring and replacement of faulty parts within warranty, but not panel cleaning or civil work.
How long does installation take?
Material is delivered 20–25 working days after the advance payment. Installation on your roof usually takes 1–2 days. The net meter is fitted by BESCOM after inspection, which adds a few weeks depending on your sub-division.
