On-Grid vs Hybrid vs Off-Grid Solar: Which Is Best for Your Home?
For most Pakistani homes in 2026, a hybrid solar system with a battery is the best fit. An on-grid system has no backup during load shedding, and after net billing replaced net metering, exported units earn far less than they used to. An off-grid system works without WAPDA but needs a large battery. A hybrid system uses solar first, a battery for the evening and the grid as backup. Below we compare all three in simple terms.

The short answer
- On-grid: panels and a grid-tied inverter, no battery. Cheapest, but it switches off when the grid goes down.
- Hybrid: panels, a hybrid inverter and a battery, connected to the grid. Gives backup and uses the grid when solar and battery are low.
- Off-grid: panels, inverter and battery with no grid connection at all, or the grid used only as a charger.
If you face load shedding, pick hybrid. If you have a stable supply and only want to cut the bill in daytime, on-grid can make sense. If you have no grid connection, you need off-grid.
How an on-grid system works
An on-grid inverter turns panel power into AC and feeds your house. Any extra goes to the grid through a net billing meter. At night you buy from the grid.
The weak point is safety shutdown: by design, a grid-tied inverter stops when the grid fails, so you get no power during load shedding even on a sunny day. Since February 2026, exported units are paid at the National Average Energy Purchase Price, reported at about Rs 8 to 11 per unit, while imports cost roughly Rs 37 to 55 (Dawn, 10 Feb 2026). That makes a no-battery system less attractive than before. See our net billing guide (Net Metering and Net Billing in Pakistan (2026 Rules)).
How a hybrid system works
A hybrid inverter manages three sources: panels, battery and grid. In the day, solar runs the house and charges the battery. In the evening, the battery takes over. When both are low, the inverter draws from the grid. During load shedding it switches to battery automatically.
There are two kinds in Pakistan:
- On-grid hybrid: can also export surplus under net billing. Our 10.35kW and 20.7kW packages use the Deye SUN-10K-SG04LP3, which supports grid export.
- Off-grid hybrid: uses the grid to charge and run loads but never exports. Our smaller packages use Growatt SPF series or Inverex inverters that work this way, so no DISCO approval is needed.
Solar vs UPS and generator
Many homes already have a UPS with a battery or a petrol generator. A UPS only stores grid power, so it cannot cut your bill, and it drains during long outages. A generator gives backup but costs fuel and makes noise and smoke. A hybrid solar system does both jobs: it charges the battery from the sun for free, runs the house in daytime, and keeps the lights on in load shedding. If you already own a lead-acid battery, ask whether it can be reused with a hybrid inverter of the same battery voltage, but old batteries often hold much less charge than their label says.
How an off-grid system works
A true off-grid system has no grid link. Everything you use at night must come from the battery, so the battery bank and panel array must be bigger, and cloudy days are a real limit. It suits farms, remote homes and places with very long outages.
Many Pakistani installers use the word off-grid for off-grid hybrid inverters connected to WAPDA as a backup charger. Ask the seller which one they mean. Our off-grid page (Off-Grid Hybrid Systems) lists the packages that work this way.
Side-by-side comparison
- Backup in load shedding: on-grid none; hybrid yes; off-grid yes.
- Battery: on-grid none; hybrid yes; off-grid yes, usually larger.
- Grid export: on-grid yes; on-grid hybrid yes; off-grid hybrid no.
- DISCO approval: needed for any system that exports; not needed for a non-exporting system.
- Upfront cost: on-grid lowest; hybrid middle; off-grid highest for the same night use.
- Running cost: batteries need replacing over time; tubular batteries sooner than lithium (see Lithium vs Tubular Battery: Which Is Better for Solar?.
- Best for: on-grid, stable areas with daytime load; hybrid, most homes and shops; off-grid, sites without a grid.
What you pay for in each system
The panels cost about the same in all three designs. The difference is in the inverter and the battery.
- On-grid: a grid-tied inverter, structure, wiring and the net billing meter and paperwork. No battery, so the lowest upfront cost.
- Hybrid: a hybrid inverter that can manage a battery, plus the battery itself. The battery is often the largest single cost after the panels.
- Off-grid: a bigger battery bank and often extra panels, because there is no grid to fall back on during cloudy days.
Also count running costs. A battery wears out and must be replaced one day; a tubular bank sooner than lithium. An on-grid system has no battery to replace, but every load shedding hour is lost. Net billing paperwork also costs time and fees, including NEPRA's one-time concurrence fee of Rs 1,000 per kW under the 2026 regulations.
Why net billing pushes buyers towards hybrid
Under old net metering, the grid acted like a free battery: export in the day, take back at night one-for-one. Net billing ended that for new users. Now every unit you store and use yourself is worth several times a unit you export.
So the smarter design in 2026 is to size panels for daytime use, add enough battery for evening use, and treat exports as a small bonus. That is exactly what a hybrid system does.
Common mistakes when choosing
- Buying on-grid to save money in an area with daily load shedding, then finding the house dark on sunny afternoons.
- Assuming every hybrid inverter can export. Off-grid hybrid models, such as the Growatt SPF series, are built not to feed the grid.
- Planning a large grid-tied system without checking the sanctioned load. Under the 2026 rules the system cannot exceed it.
- Buying a small battery and expecting a whole night of AC. Size the battery for what you really run after sunset.
- Forgetting the phase. Most export applications need a three-phase connection, see the three phase page (Three Phase Systems).
- Ignoring future loads, such as a second AC or an electric car charger, when choosing the inverter.
Which one should you choose?
- Small house, fans, lights and a fridge, frequent load shedding: an off-grid hybrid package such as 1kW (1kW Solar System) or 3kW.
- Medium home with one or two ACs: a 5kW (5kW Solar System) or 7kW off-grid hybrid package.
- Large home, office or shop on three-phase that wants to export: the 10.35kW or 20.7kW on-grid hybrid packages (On-Grid Hybrid Systems).

Advantages and disadvantages at a glance
On-grid: advantages are the lowest upfront cost, no battery to replace and the option to export; disadvantages are no backup in load shedding and low export credit under net billing.
Hybrid: advantages are backup, lower bills and flexibility; disadvantages are the extra cost of a battery and its eventual replacement.
Off-grid: advantages are full independence from WAPDA and no paperwork; disadvantages are a larger battery bank, limits on cloudy days and the highest cost for the same night use.
