Use your own generation
Run everyday loads from rooftop solar when the system is producing.
Residential solar
Make more of the
sun over your home.
A well-designed solar system can supply more of your household's electricity from your own roof. We design around your home, your usage and what you want the system to do—now and in the years ahead.

Why residential solar
Turn your roof into part of your energy system.
Solar panels generate electricity whenever there is usable daylight—not only in full summer sun. Your home uses that electricity first, reducing the amount drawn from the grid at that moment.
The best results come from matching generation to the way your household uses power. That is why we start with your actual energy profile, rather than a one-size-fits-all package.
Plan for electrification
Allow for future loads such as an EV charger, heat pump or electric hot water.
See how it performs
Monitor generation and consumption, where supported by the selected system.
How it works
Solar power, made straightforward.
During daylight hours, the system continually balances what your panels produce with what your home needs.
Panels generate DC power
Roof-mounted panels convert daylight into direct-current electricity.
The inverter makes it usable
An inverter converts that power into AC electricity for your household circuits.
Your home uses solar first
Appliances use available solar generation before drawing additional power from the grid.
Energy is balanced
Surplus may charge a battery or export to the grid; shortfalls are supplied by the grid.
Grid export and buy-back arrangements depend on your electricity retailer, metering and network requirements.
System sizing & options
The right size is the one that fits your household.
Panel count alone does not define a good system. We consider when you use electricity, available roof area, orientation, shading, your switchboard and any future energy plans.
- ✓Recent power bills and daytime load
- ✓Roof condition, pitch and usable orientations
- ✓Single, two-phase or three-phase supply and switchboard capacity
- ✓Battery, EV charging and expansion plans
Solar-first
A grid-connected system focused on supplying daytime household use, with monitoring included where compatible.
Solar + battery-ready
Plan the inverter and electrical design so storage can be considered later without boxing in your options.
Solar + battery
Generate, store and manage energy as one integrated system, designed around your objectives.
Solar + battery
Keep more flexibility in your energy plan.
A battery can store surplus solar for use later in the day, help reduce grid imports at selected times, and—when specifically designed and configured for it—support nominated circuits during an outage.
Battery capacity, power output and backup behaviour vary by product and installation. We explain these limits clearly before recommending a system.
Why Highway Solar

Frequently asked questions
Useful answers before you get started.
Every home is different. A site assessment is the best way to turn these general answers into a practical recommendation.
Does solar work through a New Zealand winter?
Yes. Panels generate whenever there is usable daylight, although output varies with season, weather, temperature, orientation and shading. We model expected generation using the specifics of your site.
What happens when solar is not producing enough?
In a standard grid-connected system, the home automatically draws the balance from the grid. If generation exceeds current use, surplus may be exported or stored in a compatible battery.
Will solar keep my house running in a power cut?
Not by default. Most grid-connected solar systems shut down during an outage for network safety. Backup requires compatible battery equipment, changeover hardware and circuits designed for that purpose.
How do you decide how many panels I need?
We review your energy use, when that use occurs, roof constraints, budget and future plans. The recommendation is based on those inputs—not simply filling all available roof space.
What approvals or electrical work may be required?
Requirements depend on the network, retailer, metering and the existing installation. We identify the applicable steps for your property and include the relevant electrical scope in the proposal.
Should I install a battery at the same time?
It depends on your usage and priorities. We can compare solar-only, battery-ready and integrated storage approaches, including the operational limits of each.
