On-Grid vs Off-Grid Solar in Gujarat, Hybrid Explained 2026
On-grid vs off-grid solar in Gujarat. On-grid and hybrid qualify for up to ₹78,000 PM Surya Ghar subsidy, off-grid does not. Costs, batteries, Bharuch cuts.
On this page
For most city homes in Gujarat, on-grid solar is the right choice. It costs the least, it qualifies for the full PM Surya Ghar subsidy of up to ₹78,000, and DGVCL net metering does the job a battery would do on paper. A hybrid system makes sense where cuts are frequent and backup matters, and it adds roughly the cost of a battery bank. Off-grid only makes sense where there is no grid connection at all.
The three systems in plain terms
On-grid
Panels feed an on-grid inverter, which feeds your house. When the panels make more than you use, the surplus goes to the grid through a bi-directional net meter. At night or on cloudy days you draw from the grid as usual. Your bill charges only the net units you imported. There is no battery. When the grid fails, the inverter shuts down by design. We explain the meter side in detail in our post on DGVCL net metering.
Hybrid
A hybrid inverter does everything an on-grid inverter does and also manages a battery bank. Solar runs the house first, tops up the battery, and sends any surplus to the grid through the net meter. When the grid fails, the inverter disconnects from the grid and runs selected circuits from the battery and panels. You still get net metering and you still get the subsidy.
Off-grid
An off-grid system has panels, a charge controller or off-grid inverter, and a battery bank. It has no connection to the grid. Everything you use at night must come from the battery. It needs a larger battery to be dependable, and there is no net meter, so surplus power in the afternoon is simply lost once the battery is full. Farmhouses, remote sheds and sites without a DGVCL connection are where it fits.
Side by side
| On-grid | Hybrid | Off-grid | |
|---|---|---|---|
| Relative cost (same panel size) | Lowest. 3.3 kWp is about ₹1,65,000 before subsidy | On-grid cost plus roughly the battery bank | Highest per usable unit, needs a large battery |
| PM Surya Ghar subsidy | Yes, up to ₹78,000 with DGVCL net meter | Yes, on solar capacity, battery not covered | No |
| Net metering | Yes | Yes | No |
| Backup during power cut | None | Yes, selected loads | Yes, all loads the battery can carry |
| Battery replacement | Not needed | Every several years, depends on chemistry | Every several years, larger bank |
| Maintenance | Panel cleaning, yearly check | Same plus battery care | Same plus battery care, more critical |
| Best for | City homes with a stable supply | Clinics, shops with computers, villages with frequent cuts | Sites with no grid connection |
The cost figure for on-grid comes from our savings calculator at ₹50,000 per kWp before subsidy. After the ₹78,000 subsidy, that 3.3 kWp system costs you ₹87,000 and saves about ₹3,105 a month in the first year. Our post on solar panel prices in Bharuch has the full table by size.
We do not publish a fixed hybrid solar inverter price, because the inverter is the smaller part of the extra cost. The battery bank is the larger part, and it swings with chemistry, capacity and brand. A fair way to plan is to take the on-grid price for your size and add the battery bank you need. For solar with battery backup in Bharuch, we quote both versions in one proposal so the difference is plain.
Power cuts in Bharuch city and villages
This is the question that decides the choice, so it is worth being honest about it. We do not have official outage numbers by area. The pattern below is general, and your own street may differ.
In Bharuch city, in areas like Zadeshwar, Link Road and Kasak, supply is mostly steady. Cuts happen, but they are usually short or planned for maintenance. Most families here manage cuts with the home UPS they already own.
Village feeders tend to see more interruptions than the city, especially where they also carry farm load. That includes villages like Manubar, Tankariya, Dehgam and Hinglot, where we have installed systems. The monsoon adds to it everywhere. Between June and September, storms bring down lines and trip feeders across the district, and repairs can take hours. A cut in July also coincides with cloudy skies, so a hybrid battery charges less on exactly those days. Size the battery with that in mind.
Why an on-grid system switches off in a cut
People are often surprised that panels on the roof do nothing when the power goes. The reason is safety. If your inverter kept pushing power into the line during a cut, a lineman working on a line they believe is dead could be hurt. Every grid-tied inverter is required to detect the loss of grid and stop within a fraction of a second. This is called anti-islanding. A hybrid inverter gets around it by isolating your house from the grid first, then running your backup circuits from the battery.
Lithium or tubular batteries
If you go hybrid, the battery is the biggest decision and the biggest cost. We stock batteries from Microtek, Exide, Luminous, Amaron, Livguard and UTL, and we will tell you which models are in stock in each chemistry when we quote.
| Lithium (LFP) | Tubular lead-acid | |
|---|---|---|
| Upfront cost | Higher | Lower |
| Typical life | Longer, often rated for thousands of cycles | Shorter, usually replaced sooner |
| Maintenance | None | Distilled water top-up every few months |
| Usable capacity | Most of the rated capacity | About half is used for good battery life |
| Space and weight | Compact, wall-mounted options | Heavy, needs floor space and ventilation |
| Best suited for | Daily cycling, clinics, shops | Occasional backup, tight budget |
Tubular batteries are what most Bharuch homes already know from their inverter setups. They work well if someone checks the water and keeps terminals clean. Lithium costs more on day one but handles daily charge and discharge better, and there is nothing to top up. For a system that cycles every night, lithium usually costs less per year of service. For backup that runs a few times a month, tubular is often fine.
When a hybrid makes sense
A hybrid earns its extra cost when a cut costs you money or causes real trouble. These are the cases where we recommend one.
Clinics and small hospitals. A doctor cannot stop mid-consultation because the lights and the nebuliser went off. A hybrid keeps essential circuits running without the noise and fuel of a generator.
Shops and offices with computers. Billing counters, CCTV, routers and printers do not like sudden shutdowns. A hybrid with a modest battery keeps them running through the usual short cuts. Our commercial solar page covers larger setups. Note that shops and businesses do not get the PM Surya Ghar subsidy, whichever system they choose.
Homes in villages with frequent cuts. If your area loses supply for long spells, especially in the monsoon, a hybrid gives you solar savings and backup in one system instead of two.
Homes with someone working from home or a medical need. A laptop, a router and a CPAP machine or oxygen concentrator on backup can matter more than any saving.
Why most city homes pick on-grid
For a steady supply area, the numbers plainly favour on-grid. Net metering already lets you use the grid as a free store for your daytime surplus. A battery does the same job at a real cost, and it wears out. Adding a battery bank can raise the system price noticeably, while the monthly saving stays roughly the same, because the saving comes from the panels, not the battery. That lengthens the payback.
Many families solve backup another way. They keep the home UPS and battery they already own for fans, lights and the Wi-Fi, and install an on-grid system for savings. The two run side by side without any rewiring of the solar side. It is often the cheapest route to both.

Questions people ask
Does an on-grid solar system work during a power cut?
No. An on-grid inverter switches off within a fraction of a second when the grid fails. This is a safety rule called anti-islanding, so that no power flows back into lines that DGVCL linemen may be repairing. The panels keep producing but the inverter will not use that power until grid supply returns. For backup during cuts you need a hybrid inverter with a battery bank.
Is a hybrid solar system eligible for PM Surya Ghar subsidy?
Yes, as long as it is connected to the grid with a DGVCL net meter and uses ALMM-listed domestic panels. The subsidy is worked out on the solar capacity, up to ₹78,000 for 3 kW and above. It does not pay for the battery bank, so the battery cost sits fully on you. Off-grid systems with no grid connection do not qualify under PM Surya Ghar.
What is the price difference between a hybrid and an on-grid system?
A hybrid adds roughly the cost of the battery bank on top of an on-grid system of the same size, plus a smaller difference for the hybrid inverter itself. The battery is the big part, and it depends on chemistry, capacity and brand. Lithium costs more upfront than tubular. We price both options in the same written proposal so you can compare line by line.
Can I use my existing home inverter and battery with rooftop solar?
Yes, in most homes. Many Bharuch houses already have a home UPS for fans and lights. You can install an on-grid solar system and keep that UPS exactly as it is. The UPS charges from the grid and covers cuts, while the solar system cuts your bill through net metering. It is often the cheapest way to get both savings and basic backup.
Which battery is better for solar, lithium or tubular?
Lithium lasts longer, needs no water topping, charges faster and takes less space, but costs more upfront. Tubular lead-acid is cheaper and well understood, but needs distilled water every few months and usually needs replacing sooner. For a clinic or a shop that cycles the battery daily, lithium usually works out better over its life. For occasional backup, tubular is often enough.
