Off-Grid, On-Grid or Hybrid Solar: Which System Type Fits Your Property?
Before you compare panels, batteries or prices, decide what kind of system you are building. On-grid, off-grid and hybrid systems differ in cost, complexity, permitting and, importantly, what happens when the power goes out.
The three system types at a glance
| Type | Connected to the utility? | Batteries | During a grid outage | Typically suits |
|---|---|---|---|---|
| On-grid (grid-tied) | Yes | Usually none | Shuts down for safety unless designed otherwise | Homes and businesses that want lower bills and have reliable utility service |
| Off-grid | No | Yes, essential | Not affected, because there is no grid to lose | Cabins, cottages, remote sites and properties without utility access |
| Hybrid | Yes | Yes | Can supply backup power if the inverter and wiring are set up for it | Homes that want bill savings and backup power |
On-grid: the simplest way to cut a power bill
A grid-tied system sends solar power to your loads first and exports any surplus to the utility. With no batteries, it is generally the lowest-cost path per kilowatt of solar.
- Pros: lower cost, simpler equipment, no battery to maintain.
- Cons: it needs utility approval and a permit, and it does not keep your lights on in an outage. Grid-tied inverters are required to shut down when the grid fails, so the utility's crews are not endangered by power flowing back into the lines.
- Rules vary by province. Whether and how you are credited for exported power depends on your utility and province, so check before you buy.
Off-grid: independence with full responsibility
An off-grid system has no utility connection. Panels charge a battery bank and an inverter powers your loads from the batteries. Everything you use has to be generated, stored and converted on site.
- Pros: no utility connection, no monthly service charge for power you do not draw, and a good fit where extending the grid is impractical.
- Cons: you carry the whole sizing burden, batteries are a major cost, and winter is the design month. Many off-grid owners keep a generator for long cloudy stretches.
Winter planning is the difference between an off-grid system that works and one that disappoints. See our guide on how solar panels behave in Canadian winters before you size anything.
Hybrid: grid connection plus batteries
A hybrid system pairs solar with batteries and keeps the utility connection. It can store surplus for evening use and, if designed for it, power selected circuits during an outage.
- Pros: flexibility, backup capability and the option to use stored energy when it suits you.
- Cons: higher cost and more complexity. Backup power usually covers only selected circuits, not the whole building, and the inverter and wiring must be set up for that from the start.
How to choose
- No utility access? You are building an off-grid system.
- Reliable grid and the goal is lower bills? Start by pricing an on-grid system.
- Outages are a real problem for you? Look at hybrid and decide which circuits must stay on.
- Seasonal property? Consider how many months you are actually there. A smaller off-grid system may be enough.
