Your electricity use
A recent bill and the times you use power help shape a more useful starting point than household size alone.
Residential solar
Home solar, sized around how you use power.
Your bill, roof and future plans should guide the system — not a one-size-fits-all package.

A better starting point
Every home uses electricity differently.
That is why a residential solar plan should begin with your property and usage — not a generic promise.
Your roof and property
Available roof area, orientation, shading, material and switchboard condition can all affect the final design.
Your future plans
Battery storage, an EV, electric hot water or higher future demand should be considered before equipment is selected.
Choose a direction
Three ways to plan residential solar.
The right pathway depends on what you want solar to do now — and what may change later.
Solar for daytime use
Begin with an array shaped around the electricity your home can use while the sun is available.
- Lower grid electricity use during daylight hours
- A clear baseline before considering storage
Battery-ready solar
Consider future storage when choosing the inverter, even if a battery is not part of your first purchase.
- Future battery goals discussed early
- Equipment compatibility confirmed before you buy
Solar + battery
Explore storing surplus daytime generation for later use or for a clearly defined backup objective.
- Storage sized around your usage pattern
- Backup scope must be designed and confirmed
Indicative planning sizes
Compare residential starting points.
These examples make the conversation easier. Your final equipment list still needs a property and electricity-use review.

GST and include the equipment listed — panels, hybrid inverter, mounting and cabling, plus the Cell-X W10.24a battery where shown — and standard installation in Canterbury by Cell-X Solar’s registered electricians. Site-specific extras (for example switchboard upgrades, difficult roof access or long cable runs) and any lines-company or meter costs are confirmed in your quote. Outside Canterbury, ask us for a quote. Planning guides only — not final recommendations or quotes. Final size depends on your bill, daytime use, roof space and orientation, shading, switchboard, future loads and local network requirements.
Residential storage
Use more of your solar later in the day.
A battery can store surplus solar for evening use. If backup is important, the supported loads and operating limits need to be designed and clearly confirmed.

Residential solar answers
Frequently asked questions
What size solar system does my home need?
The useful starting point is your electricity bill and when you use power — not the number of people in the home alone. Roof space, shading, orientation, future loads and local network requirements also need to be reviewed before a final recommendation.
Ask about my homeDoes Cell-X Solar install the system?
Yes, in Canterbury. Package prices include standard installation by Cell-X Solar’s registered electricians, who install, connect and certify the system. Any site-specific extras and lines-company or meter requirements are confirmed in your quote. Outside Canterbury, ask us about options for your area.
Ask about my homeDo I need a battery with residential solar?
Not every home needs storage. A battery may suit a home that wants to use more solar later in the day or has a specific backup goal. Its value depends on your usage pattern, tariffs, available surplus generation, equipment and budget.
Ask about my homeCan you tell me how much I will save?
A useful estimate needs property-specific assumptions, including expected generation, self-consumption, electricity tariffs and export rates. Any estimate should show those assumptions rather than present savings as a guarantee.
Ask about my homeWhat could change the final price?
Roof space and access, shading, mounting requirements, cable lengths, switchboard condition, inverter compatibility and the equipment you choose can all change the final price. These are confirmed in your quote before you decide.
