Our Solar Services
Solar, under one roof
Solar is what we do best. Explore our full range of solar services below — every system is designed, installed and supported by our own licensed electricians.
Home solar
Sized to your usage
Residential Solar
Rooftop solar for your home
Every home uses power differently. We design your system around your household’s usage, roof orientation and budget — so you get a system sized around your actual needs, not simply the biggest system possible.
From single-storey bungalows to double-storey new builds, our licensed electricians handle everything: design, approvals, installation and grid connection, with a tidy finish we’re proud to put our name on.
- Custom system design based on your actual power usage
- Tin, tile and flat roof mounting systems
- Premium panels and inverters with long warranties
- Battery-ready — add storage now or in the future
3-Phase
Commercial systems
Commercial Solar
Solar that works for your business
Power is one of the biggest overheads for many Auckland businesses — and one of the easiest to reduce. Our commercial-grade 3-phase solar systems are built to offset daytime usage, when your business consumes the most.
We work around your operating hours to minimise disruption, and design systems that scale with your business — from small workshops to large commercial roofs.
- 3-phase systems sized to your daytime load
- Reduce overheads and reduce exposure to rising energy costs
- Lower your emissions and strengthen your brand
- Installed around your business hours
Day & night
Power on your terms
Battery Storage
Use your own solar, day and night
Without a battery, surplus solar is typically exported to the grid, where the value you receive may be lower than the cost of buying electricity from the grid later. Battery storage can change that — storing excess solar so you can use more of your own energy after the sun goes down.
We install and configure leading battery systems alongside new solar installs, or retrofit them to existing systems — with backup options that keep essentials running during outages.
- Store surplus solar instead of exporting it cheaply
- Maximise self-consumption and reduce grid reliance
- Backup power options for selected circuits during outages
- Add to a new system or retrofit to an existing one

Solar System Upgrades
Boost your existing solar array
Your household changes — an EV in the driveway, a growing family, a new heat pump. If your current system isn’t keeping up, we’ll upgrade it so it does, whether or not we installed the original.
From extra panels and higher-capacity inverters to battery retrofits and smarter monitoring and controls, we design upgrades that work with what you already have.
- Panel additions and system expansions
- Inverter upgrades and replacements
- Battery retrofits to existing systems
- Smarter controls and monitoring
Peak output
For the long run
Solar Maintenance
Keep your system running safely
A solar system is a long-term investment — and like any investment, it performs best with a little care. Regular servicing helps keep your system operating safely and efficiently. and catches small issues before they become expensive ones.
Our licensed electricians inspect, service and repair solar systems across Auckland, whether or not we installed them.
- Health checks, inspections and fault-finding
- Inverter repairs and replacements
- Performance testing and monitoring reviews
- Servicing for systems installed by anyone

Everything you might be wondering before making the switch — and if we’ve missed something, just give us a call.
How much can solar save me on my power bill?
It depends on your usage, roof and system size — many Auckland households can significantly reduce their power bills, and our savings estimator can give you an indicative estimate in under a minute. We confirm the real numbers during your free consultation.
Does my roof suit solar panels?
Most do. North-facing roofs are ideal, but east and west work well too. We look at orientation, pitch, shading and roof condition during the site assessment and design around what you have — tin, tile or flat.
Do I need a battery, or can I add one later?
You can start with solar only and add storage whenever it suits. We design every system battery-ready, so adding one later can be straightforward, depending on your existing system and inverter.
How long does a solar installation take?
Most residential installs are completed in one to two days on site. Design, approvals and grid connection are handled as part of the process, and we handle the paperwork for you.
Can you service or upgrade a system you didn’t install?
Yes. We service, repair and upgrade systems installed by others — extra panels, a battery retrofit, an inverter replacement or a health check are all work we do regularly.
Is the work certified and compliant?
Yes. Every installation is completed by our own licensed electricians and includes the required certification and compliance documentation. Every installation is completed by our own licensed electricians and comes with the required certification, compliance documentation and grid-connection process.
