On-grid, off-grid, or hybrid — which solar system is right for you?
The type of solar connection you choose affects your cost, your savings, and how your system behaves during a power cut. Here's a clear, no-jargon explanation of each.
Every solar installation falls into one of three categories, based on how it connects to the electricity grid and whether it includes battery storage. Choosing the right one depends on how reliable your grid power is, your budget, and whether backup during outages matters to you.
We'll help you choose the right type during your free site survey — but understanding the basics upfront will help you ask the right questions.
On-Grid Solar System
Connected directly to the electricity grid, with no battery. Surplus power is exported to the grid via net metering.
Advantages
- Lowest upfront cost of the three options
- Simple design, fewer components to maintain
- Net metering lets you earn credit for surplus power exported
- Fastest payback period
Disadvantages
- Shuts down automatically during a grid power cut (for safety)
- No battery backup for outages
- Fully dependent on grid availability to function
Suitable for: Homes and businesses with reliable grid power who want maximum savings with the lowest investment.
Typical cost: Lowest of the three types
Savings: Highest return relative to investment, due to lower upfront cost
Off-Grid Solar System
Fully independent of the grid, storing generated power in batteries for use anytime — day or night.
Advantages
- Works completely independent of grid power
- Full backup during outages, day or night
- Ideal for locations with no reliable grid connection
Disadvantages
- Highest upfront cost, due to battery storage
- Battery replacement adds to long-term cost
- No net metering credit — any unused capacity is simply stored, not exported
Suitable for: Remote locations with unreliable or no grid connection, or where complete independence from the grid is the priority.
Typical cost: Highest of the three types, driven by battery capacity
Savings: Strong for locations with expensive or unreliable alternatives (diesel gensets, frequent long outages)
Hybrid Solar System
Combines grid connection with battery storage — you get net metering credit and backup power during outages.
Advantages
- Backup power during grid outages, unlike pure on-grid systems
- Still eligible for net metering credit on surplus power
- Flexible — draws from solar, battery or grid depending on availability
Disadvantages
- Higher upfront cost than on-grid, due to battery
- More components to maintain than a simple on-grid system
Suitable for: Homes and businesses that want backup power during outages without going fully off-grid.
Typical cost: Between on-grid and off-grid, depending on battery size chosen
Savings: Good balance of savings and reliability for areas with occasional outages

Connection types — frequently asked questions
Most homes with reasonably reliable grid power choose on-grid systems, since they offer the fastest payback. Hybrid systems are increasingly popular in areas with occasional outages.
In many cases, yes — depending on your inverter type and system design. We can advise on future-proofing your system if you think you may want to add battery backup later.
Yes, hybrid systems that remain connected to the grid are generally eligible for net metering, in addition to having battery backup — giving you the benefits of both.
Battery lifespan varies by chemistry and usage, typically ranging from 5–10+ years. We'll explain warranty and expected life for the specific battery recommended for your system.
