How an off-grid solar system works
During the day, solar panels power your appliances and charge a battery bank at the same time. At night and on cloudy days, the batteries take over. A solar inverter (PCU) in the middle manages charging and converts the batteries' DC power into normal 230 V AC for your home.
Because there's no grid connection, the system has to be sized properly: enough panels to refill the batteries every day, and enough battery capacity to carry your evening and night loads. That's why we start with a list of your appliances.
Have a BESCOM connection but frequent power cuts? A hybrid solar system gives you backup and the PM Surya Ghar subsidy.

What size off-grid system do you need?
Enter how many of each appliance you'll run. The calculator works out your daily energy, the inverter, panels and batteries you need, and the nearest Eltron package.
Estimates only. Assumes about 4 units per kWp per day in Karnataka, 25% system losses, 50% usable depth of discharge for tubular batteries and 90% for lithium. Pumps and ACs need extra inverter capacity for starting current. We confirm sizing after a site visit.
Off-grid vs on-grid vs hybrid solar
Off-grid is the right answer when the grid isn't there. Where it is, one of the other two usually gives better value.
| Off-grid | On-grid | Hybrid | |
|---|---|---|---|
| Needs a grid connection | No | Yes | Yes |
| Works during power cuts | Yes | No | Yes |
| Batteries | Essential | None | Yes, for backup |
| Net metering / export to BESCOM | No | Yes | Yes |
| PM Surya Ghar subsidy (homes) | No | Up to ₹78,000 | Up to ₹78,000 |
| Typical cost for a home | Medium to high (battery-heavy) | Lowest | Highest |
| Best for | Farms, remote homes, estates, sites with no or very poor grid | City homes and businesses with reliable supply | Homes that want savings plus backup |
Is off-grid solar right for you?
We'd rather sell you the right system than the biggest one.
Go off-grid if…
- There's no electricity connection at your farm, estate or plot, or getting one is expensive
- Your supply is so unreliable that you live with long daily outages
- You need power at a construction site or new house while you wait for a connection
- You want a self-contained system for a remote office, school, clinic or homestay
Think twice if…
- You have a reliable BESCOM connection: on-grid solar with net metering and the subsidy costs much less
- You want to run several ACs or heavy machines: the battery bank gets very large and expensive
- You can't do basic battery care: tubular batteries need water topping every few months
- You only need backup for short power cuts: a hybrid system is a better fit
What goes into an Eltron off-grid system
- Solar panels: 600 Wp TOPCon modules (Loom), on a galvanised or elevated steel structure designed for your roof.
- Solar inverter (PCU): UTL Gamma+ for smaller systems and Alfa+ for 3.5 kVA and above, with a built-in solar charge controller.
- Batteries: UTL or Sakthi C10 tubular batteries, or a lithium (LFP) battery for longer life and less maintenance.
- Protection: DC and AC distribution boxes, lightning arrester with 16 sq mm wire, and three earthing pits.
- Wiring: Polycab 4 sq mm DC and AC cables.
Choosing your battery
| Tubular (C10) | Lithium (LFP) | |
|---|---|---|
| Upfront cost | Lower | Higher per kWh |
| Usable capacity | About 50% | About 90% |
| Maintenance | Distilled water top-up every few months | None |
| Typical life | About 4–6 years | 8–10+ years |
| Space and weight | Large, heavy | Compact |
Life depends on depth of discharge, temperature and care. Warranty terms are set by the battery manufacturer and stated in your quote.

What Eltron customers say on Google
★★★★★“We recently completed a 65 kW solar power installation for our apartment complex with Eltron Energies, and the experience was outstanding from start to finish… The project was completed on time, and the energy savings have already started kicking in.”
★★★★★“I am very much pleased and happy about the service and the quality of M/s Eltron Energy Private Limited who installed Solar Panel on my roof top. The quality of the panels, fabrications, Inverter etc are upto the mark. Even after sales service is also excellent.”
★★★★★“The entire process was Good and hassle-free, with their team providing excellent guidance and support throughout. The system is performing efficiently, and the cost was very reasonable compared to other options in the market.”
★★★★★“We installed a 5 kW solar on-grid setup. Our electricity bill has become zero. Sometimes in winter, the electricity bill even goes negative, because BESCOM refunds us money.”

Off-grid solar FAQs
What is the price of an off-grid solar system in Bangalore?
Eltron's complete off-grid systems start at ₹54,800 for 1 kVA and ₹83,900 for 1.5 kVA. A 3 kVA system with 2.4 kWp of panels and four 200 Ah batteries costs ₹2,02,200, and a 5 kVA system ₹2,68,900. Prices include GST, delivery and installation; the final price depends on your battery bank and site.
What is the price of a 3 kW off-grid solar system?
Our 3 kVA off-grid system costs ₹2,02,200 including GST and installation. It includes four 600 Wp TOPCon panels (2.4 kWp), a UTL 3 kVA 24 V solar inverter and four 200 Ah tubular batteries. A lithium battery option is quoted on request.
Is there a government subsidy for off-grid solar?
No. The PM Surya Ghar subsidy of up to ₹78,000 applies only to grid-connected rooftop solar for homes. If you have a BESCOM or other DISCOM connection, an on-grid or hybrid system lets you claim it.
What is the difference between off-grid, on-grid and hybrid solar?
Off-grid systems run on panels and batteries with no grid connection. On-grid systems connect to the grid, export surplus power through net metering and have no batteries, so they switch off in a power cut. Hybrid systems connect to the grid and also have batteries for backup.
How long do off-grid solar batteries last?
Tubular (C10) batteries typically last about 4–6 years with regular water topping and correct sizing. Lithium (LFP) batteries typically last 8–10 years or more and need no maintenance. Deep, frequent discharges and high temperatures shorten battery life.
Can an off-grid solar system run a water pump or AC?
Yes, if it's sized for them. Motors draw a high starting current, so the inverter must be large enough, and the battery bank must cover their running hours. A 1 HP pump is usually fine on a 5 kVA system; air conditioners need a much larger system and battery bank.
How much roof space does an off-grid solar system need?
Plan for about 80–100 sq ft of shadow-free roof per kW of panels. A 3 kVA system with 2.4 kWp of panels needs roughly 200–250 sq ft. Panels can also go on an elevated structure or on the ground at farms.
Can I connect my off-grid system to the grid later?
Most solar PCUs can also charge the batteries from a grid or generator supply when one is available, but they can't export power or use net metering. To get net metering later, the inverter has to be changed to an on-grid or hybrid model; the panels can usually be reused.
Do you install off-grid solar outside Bengaluru?
Yes. We install off-grid systems across Karnataka, including rural and remote locations, from our branches in Bengaluru, Ballari and Kalaburagi.
