Residential Solar Panel Installation Across Auckland
Solar for South Auckland and Franklin Homes
BW Henderson Electrical designs and installs residential solar across South Auckland and Franklin, working out of our depot at Takanini. We have been wiring properties in this part of Auckland since 1952, and that matters more for solar than it sounds — the roof is only half the job. The other half is the switchboard, the mains and the connection back to your lines company.
We are EWRB-registered electricians and we do the whole thing in one place: design, consent where it is needed, installation, switchboard work and grid connection. Systems come with a 30-year linear power warranty and are supplied by Solar Wind, one of New Zealand’s leading distributors.
This page covers solar for homes. If you are looking at solar for a business or industrial site, see our commercial solar panel installations.
Why Choose BW Henderson for Solar Panel Installation?
Franklin Roofs Are Not Suburban Roofs
A lifestyle block at Waiuku, Clarks Beach or Glenbrook usually has roof area a city property can only dream of, and a daytime load — bore pumps, sheds, workshops, irrigation — that lines up almost exactly with when solar is generating. That combination makes rural Franklin some of the best solar ground in Auckland.Where Battery Storage Earns Its Place
Out here, storage is a practical question rather than an upsell. Rural feeders go down more often than suburban ones and stay down longer. If you have already lost power for most of a day this winter, a solar and storage system is doing two jobs at once — cutting the bill and keeping the pump, the freezer and the lights running when the line is out.Suburban South Auckland
On a standard Papakura, Takanini or Manurewa roof the sums are different but still stack up: a grid-tied system sized to your daytime base load, exporting what you do not use. The limiting factor is more often the switchboard than the roof. Plenty of the boards around here are full and some still carry rewireable fuses, and that has to be sorted before an inverter goes anywhere near them. We tell you at quote stage, not on installation day.One Contractor from Design to Grid Connection
System design, council consent where it is required, installation, switchboard work and the connection with your lines company — all handled by us, rather than split between a solar company and whichever electrician they subcontract on the day.

Solar Panels Auckland - FAQs
How much do solar panels cost in Auckland?
How much do solar panels cost in Auckland?
The cost of a residential solar system in Auckland depends on the size of the system and whether you include battery storage. Our starter solar solution (4.6kW with 10.2kW battery) is designed for homes looking to cover 50–60% of their electricity needs. Our most comprehensive package (13.8kW with 24.6kW battery storage) suits homes seeking maximum energy independence. Contact us for a free, no-obligation quote tailored to your home and energy usage.
How many solar panels do I need to power my Auckland home?
How many solar panels do I need to power my Auckland home?
The number of panels depends on your household’s energy consumption, your roof size and orientation, and how much of your electricity bill you want to offset. Most Auckland homes with average energy usage (8,000–10,000 kWh per year) benefit from a system between 4.6kW and 13.8kW. Our team will assess your situation and recommend the right system size for your needs and budget.
How long do solar panels take to pay for themselves in New Zealand?
How long do solar panels take to pay for themselves in New Zealand?
Most residential solar systems in New Zealand pay for themselves within 7–10 years, depending on the size of the system, your electricity usage, and your grid export rate. With Auckland power prices continuing to rise, the payback period is getting shorter. After payback, you benefit from significantly reduced power bills for the remaining life of the system — typically 25–30 years.
Do I need council consent for solar panels in Auckland?
Do I need council consent for solar panels in Auckland?
Most residential solar installations in Auckland do not require building consent, provided the panels are flush-mounted on the roof and the installation meets the relevant standards. However, grid connection does require an application to your lines company. BW Henderson handles all consent and grid connection paperwork as part of our installation service — you do not need to manage this yourself.
Can I add battery storage to my solar system later?
Can I add battery storage to my solar system later?
Yes. Our solar systems are designed to be expandable. If you start with a grid-tied system and want to add battery storage later, we can retrofit a battery to your existing system. Our LiFePO4 battery storage systems are also scalable — you can add capacity as your energy needs grow. Ask us about future-proofing your installation when you get your quote.
