Use more power in daylight
Homes with daytime loads can use solar directly. Hot-water timing, EV charging and appliance scheduling can improve self-use without a battery.
Residential solar
Residential solar panels for Christchurch homes.
Use less grid power, prepare for future storage or build backup into the system from day one. We explain what each option changes before you spend.
Use most power after sunset
A battery may be more useful when evening demand is high. We compare storage with simpler ways to move loads into solar hours.
Understand batteries →Planning a new build
Early planning helps with roof space, cable routes, inverter position, switchboard capacity, hot-water control and future EV charging.
Want backup power
Solar alone normally does not keep a home powered during an outage. Backup needs a compatible system and a clear plan for essential loads.

MAKE THE ESTIMATE MOVE
Rotate the house. Fill four roofs. Build the battery stack.
Try panels on each compass roof, compare grid-tied, hybrid and battery systems, then change storage from 5 to 35 kWh and watch the house and indicative price respond.

THREE COMMON PATHS
Choose the flexibility you actually need.
Bigger is not automatically better. The useful system is the one that matches the house, budget and reason you are installing solar.
01
Grid-tied solarA straightforward way to reduce grid purchases when daytime use is strong.
02
Battery-ready solarA compatible hybrid inverter can keep the storage option open for later.
03
Solar + batteryStore daytime generation for evening use and add backup where it is properly designed.
A BETTER FIRST ESTIMATE
What to send us.
You do not need a perfect brief. These details let us start with a recommendation that is relevant to your actual property.
- Your addressSo we can review roof orientation, available area and likely shading.
- A summer and winter billSeasonal use is more useful than judging the home from one month.
- Roof and switchboard photosInclude the meterboard and the area where an inverter or battery could go.
- Your main goalBill reduction, future battery, backup, EV charging or a new-build plan.
- Future electrical loadsTell us about an EV, spa, heat pump, workshop or planned extension.
- Your normal usage timesDaytime, evenings, weekends and any periods when the house is usually empty.
HOME SOLAR QUESTIONS
What homeowners ask first.
We will confirm the site-specific details before recommending equipment.
Will solar work on cloudy days?+
Yes, at a lower output. Panels use daylight rather than heat. A realistic design considers annual generation, roof direction and seasonal variation—not only perfect summer conditions.
Do panels need to face north?+
North is useful, but east- and west-facing roof sections can also be practical depending on your usage times, shading and available space.
Will installers damage my roof?+
A careful installation starts with roof condition, fixing points, access and cable routes. The team protects the property, uses the correct mounting approach and leaves the work tidy.
Can you include hot-water or EV control?+
Yes, where it suits the system and existing installation. These loads can often be scheduled to use more solar during the day.
