Solar Power and Battery Installation Auckland
The Conduction Company designs, installs, and certifies solar and battery systems across Auckland. Before quoting anything, we read your actual power bills and work out what a system would do at your property, on Auckland numbers. If the sums do not work, we tell you that.
Are You Weighing Up Solar for Your Property?
Solar is a large spend and most of the advice about it comes from people selling panels. The Conduction Company starts with your actual power bills rather than a roof measurement, so the answer comes out of how your household really uses power. We also check the things a panel salesperson will not, including whether your switchboard can take the system and whether the network will approve the connection.
Solar and Battery Services in Auckland
The Conduction Company designs, installs, and certifies solar and battery systems across Auckland. It starts with your power bills, modelled against Auckland generation figures, so you see what a system would actually save at your property before anyone talks about panels.
Solar Panel Installation
Full residential and commercial solar installation, from the roof mounting through to the switchboard and the final certificate. The Conduction Company uses registered electricians on every job, so the panels, the wiring, and the compliance paperwork are all one company.
Home Battery Storage
A battery is what turns solar from a daytime saving into an all day one. In New Zealand there is no upfront subsidy and exporting power back to the grid pays poorly, so the value is in using what you generate rather than selling it. The Conduction Company sizes the battery against how your household actually uses power, not against the roof. The Conduction Company explains how much a home battery costs to add in a separate guide.
The Conduction Company's guide to running a house on solar power only covers off-grid sizing, winter, and generators.
Power Bill Assessment and System Sizing
Send us your power bills and The Conduction Company models what solar and battery would do at your property, using Auckland generation figures rather than Australian rules of thumb. You get an honest answer before you spend anything.
The Conduction Company's full guide to what solar costs in Auckland and how long it takes to pay back walks through the numbers.
Hot Water Load Shifting
Your hot water cylinder is usually the biggest single load in the house. Shifting it to run on solar during the day is one of the cheapest ways to lift the value of a system, and The Conduction Company sets it up as part of the install. When a cylinder is due for replacement, The Conduction Company's guide to heat pump hot water in Auckland explains how a hot water heat pump pairs with solar.
Solar Integrated EV Charging
Charge the car off the roof. The Conduction Company installs EV chargers that talk to the solar and battery system, so the car charges on surplus generation rather than on grid power.
Switchboard Upgrades for Solar
Plenty of Auckland switchboards are not ready for solar. The Conduction Company assesses the board as part of the quote and does any upgrade in the same visit rather than sending a second contractor.
Grid Connection Applications
Every grid connected system needs approval from the network company before it can export. The Conduction Company files the Vector distributed generation application and handles the paperwork, including the protection settings the network requires.
The Conduction Company's step-by-step guide to switching to solar power in Auckland, from first call to switch on shows where the application fits.
Solar Inspection and Certification
The Conduction Company has a registered electrical inspector in house, endorsed to inspect grid-connected solar, so your inspection is done in house, by someone who had no hand in the installation.
Solar System Servicing and Repairs
Existing system not performing, or inherited one with the house? The Conduction Company tests it, finds the fault, and tells you what it needs.
Solar Panel Removals
Roof work, a reroof, or an old system coming off. The Conduction Company removes solar safely and leaves the equipment on site with you.
The Equipment The Conduction Company Installs
Sigenergy is The Conduction Company's primary solar and battery supplier. It is an all in one system: the inverter, the battery, and the EV charging all come from one manufacturer and run through one app, so there is a single place to see what the house is generating, storing, and using, and a single manufacturer behind the warranty rather than three pointing at each other.
The Conduction Company chose Sigenergy after assessing the gear directly, and we install and commission it ourselves rather than subcontracting it out.
Why Choose The Conduction Company for Solar?
Lifetime Workmanship Guarantee
The Conduction Company backs its solar and battery work with the same Lifetime Workmanship Guarantee as every other job we do. Solar is not carved out and it is not time limited. The panels, inverter, and battery carry their own manufacturer's warranty alongside it.
SEANZ Accredited Solar Installers
The Conduction Company is accredited by the Sustainable Energy Association of New Zealand and is a Master Electricians member, so the work is checked against the industry's own standards, not just our own.
Registered Electricians and an Electrical Inspector
Solar is electrical work. The Conduction Company has registered electricians and a registered electrical inspector in house, which means the install, the switchboard, and the certificate are one company's responsibility rather than three.
We quote on facts, not guesses

That way you know exactly what you're buying and the total cost, with no surprises.

Solar and Battery Installation Across Auckland
A SEANZ accredited solar installer
The Conduction Company is a SEANZ accredited solar installer. SEANZ is the Sustainable Energy Association of New Zealand, the industry body for solar and battery storage here. It sits outside both government and the electricity supply industry, which is what makes it worth belonging to.
- A company with an address, not a door knockerSolar in New Zealand has a long history of high pressure selling from outfits that are gone by the time the system needs attention. An accredited installer is a known business inside the industry body.
- Registered electricians on every jobThe Conduction Company's own registered electricians do the install and the certification. Nothing on your switchboard is subcontracted to a stranger.
- Kept up with the industry, not just the productMembership means The Conduction Company sees the standards and network rule changes as they come, rather than after a job fails an inspection.
Panels
The solar panels The Conduction Company installs
There is no single best panel. The Conduction Company works with four module manufacturers and chooses between them on the roof in front of it, because pitch, shading, available area, budget, and what the property actually needs to generate all change the answer. You are told which module is going on your roof, and why, before you accept the quote.
Anchor by Panasonic
The Conduction Company installs this N-Type TOPCon dual glass bifacial module, all black. Panasonic rates it at up to 22.9 percent efficiency, with a temperature coefficient of 0.29 percent per degree C. The 25 year product warranty and the 30 year performance warranty are Panasonic's own.
Trina Solar
Bifacial dual glass modules from one of the largest module manufacturers in the world.
Suntech
Ultra series modules, installed by The Conduction Company. Suntech, the manufacturer, has been building photovoltaic panels since 2001.
Jinko Solar
Tiger Neo N-type modules, a high output panel for roofs that need as much generation as the space allows.
Module availability changes. If a panel named here is not available when your job is booked, The Conduction Company tells you what is being substituted and why before any work starts.
Sigenergy: one cabinet instead of four boxes on the wall
Sigenergy is the system The Conduction Company fits on most solar and battery jobs. A SigenStor stacks the inverter, the battery and the power electronics into a single unit, so the switchboard end of the job is one cabinet rather than a row of separate boxes, and the battery can be added to later without replacing what is already on the wall.
- Solar, storage and EV charging in one systemThe inverter, the battery and the car charger are managed together instead of three products negotiating with each other.
- Battery capacity you can add toModules stack, so a system sized for today can be extended without a second installation from scratch.
- Backup when the grid goes downWith a gateway fitted, nominated circuits keep running through an outage. The Conduction Company explains why a grid-tied system switches off in a power cut, and what keeps the lights on, in how solar power works on an Auckland house.
- Installed and certified by the people who sold itThe Conduction Company's own registered electricians do the install, the switchboard work and the network application.
mySigen app
You can see what the system is doing, any time
Every Sigenergy system The Conduction Company installs is handed over with the mySigen app set up on your phone. It shows what the panels are making, what the house is using, what is going into and out of the battery, and what is being bought from or sold to the grid. If a system is not performing the way it should, this is where you see it first.
Screens shown are Sigenergy product images. What your app shows depends on the system installed at your property.
Storage
SunVolt by Panasonic
Where a property suits it, The Conduction Company also installs the Panasonic SunVolt energy storage system. It does the same job as any home battery, holding what the panels make during the day so the house can use it through the evening peak, and carrying nominated circuits through an outage.
- Panasonic lithium-ion cellsPanasonic has been making lithium-ion batteries for decades, and the SunVolt is built on that.
- A second option, not a lesser oneWhich battery The Conduction Company recommends depends on the property, the switchboard and what you want the system to do in an outage.
The Conduction Company mounts its solar panels on Clenergy racking, the rails, clamps, and brackets that hold an array to your roof. It comes pre-engineered. Clenergy's New Zealand certificate, signed by a chartered engineer, covers wind, snow, and earthquake loads on tin and tile roofs. Fitted to Clenergy's instructions and inside its limits, the racking needs no one-off engineering design, so your job is not held up waiting on an engineer. We still check your roof framing can carry the load, because the certificate covers the racking, not the roof.

Frequently Asked Questions
Solar Power and Battery Installation in Auckland
How long will a 10kWh battery last?
Through an evening of lights and basic electronics, and maybe to the morning, says The Conduction Company, but not a full day. A 10 kWh battery holds about 9 kWh you can use, and cooking or heating runs it down fast. The Conduction Company's guide to running a house on solar power only works through an example.
What is the best solar battery in NZ?
For The Conduction Company, it is Sigenergy, its first choice and main battery supplier in New Zealand, for how well its systems work and how easy its app is to use. Where a property suits it, The Conduction Company also installs Panasonic's SunVolt storage system.
Is it better to have more solar panels or a bigger battery?
In most cases more panels, says The Conduction Company. Panels are the cheap part and usually give the better return and the shorter payback, while a battery is expensive and pushes payback out. A battery earns its place for a family out all day with big bills, and as backup where power cuts are common.
How does solar power work in NZ?
Solar panels make direct current from sunlight, and an inverter turns it into the AC power a house uses. The Conduction Company sets systems up to use solar first, then the battery, then the grid, and spare power fills the battery before any is exported. The Conduction Company's guide to how solar power works on an Auckland house covers the whole path.
Can I charge my EV off the solar?
Yes. The Conduction Company installs EV chargers that run off surplus solar generation, so the car charges on what the roof makes rather than on grid power.
What brand of solar and battery do you install?
Sigenergy is The Conduction Company's primary supplier. The inverter, battery, and EV charging come from the one manufacturer and run through one app, which keeps the system simpler to operate and puts one company behind the warranty.
Do I need permission to connect solar to the grid?
Yes. Any grid-connected system needs approval from the network company, which in most of Auckland is Vector. The Conduction Company files that application as part of the job.
Who does the installation?
The Conduction Company's own registered electricians. Solar is electrical work and it is certified like any other electrical work, by an electrical inspector.
Do I need a battery?
Not always. A battery lifts how much of your own generation you use instead of exporting it, which is where most of the value sits in New Zealand. The Conduction Company sizes it against your usage pattern, so the answer comes out of your bills rather than a rule of thumb.
Is solar worth it in New Zealand?
It depends on how much power you use during the day, and that is why The Conduction Company reads your bills before answering. There is no upfront government subsidy here and exporting to the grid pays poorly, so the systems that pay off are the ones sized around what the household actually uses. Some properties are a clear yes, some are not, and we will tell you which one you are.
