Commercial Solar
Why Auckland Businesses Are Switching to Solar
Commercial Solar in East Tamaki and East Auckland
We install rooftop solar for warehouses, factories and commercial buildings across East and Central Auckland, including the East Tamaki and Highbrook industrial areas — load assessment, install and grid connection. Sites from Papakura south are covered by our sister company BW Henderson.
Commercial electricity prices keep climbing, and power is one of the larger fixed costs most businesses carry. Solar turns part of that from a bill you receive into an asset you own — but only if the system is sized against how your business actually uses power rather than against how much roof you happen to have.
The first commercial array we installed was our own. It sits on the roof of our workshop at 179c Harris Road, East Tamaki, and we monitor its output continuously. When we quote a commercial system, we are quoting against measured generation on an East Tamaki roof in Auckland conditions.
The East Tamaki and Highbrook Corridor
The light industrial and warehousing through East Tamaki, Highbrook and Mount Wellington is close to ideal ground for solar: large flat roofs, and a load that runs through the working day when generation is highest. We already maintain a good number of these buildings — test and tag, emergency lighting, thermal imaging of switchboards — so in many cases we know the switchboard before we ever look at the roof.

Custom Commercial Solar Design and Installation
Designed Against Your Load, Not Your Roof
We start with your consumption data. When the load falls through the day matters more than how much of it there is — a site drawing hard between 7am and 5pm suits solar far better than one running a night shift, and the system gets sized accordingly.
From there it is roof area and structure, shading, and the condition of your main switchboard and supply. On the older East Tamaki industrial buildings the switchboard is often the limiting factor rather than the roof. Because that is our own trade, it gets solved rather than handed to someone else.
Ongoing Solar Maintenance and Monitoring
We don’t set and forget. French Electrical provides ongoing maintenance, monitoring, and servicing for commercial solar installations, keeping your system generating at peak efficiency for its full working life. Our technicians identify and resolve performance issues early, protecting both your output and your return on investment.
Our Commercial Solar Panels
At French Electrical, we’re always pursuing innovative, cost-effective answers to rising energy costs. After thoroughly canvassing the market, we chose Solar Wind, a supplier with proven international credentials whose durable, high-efficiency panels are well suited to New Zealand’s variable weather.
Like us, Solar Wind is committed to environmentally conscious solutions to the world’s growing energy challenges, and bringing their panels to the New Zealand market is a genuine step toward a cleaner, greener future.
Beyond cutting your power bill and carbon footprint, the panels look the part too. With a streamlined, low-profile design available in silver or black, they sit cleanly on any commercial building. Reliable, efficient, and built to make the most of New Zealand’s sunshine hours. Let’s talk about what they can do for your business.
Commercial Solar FAQs
Savings depend on your energy usage, system size, and how much of your consumption happens during daylight hours. Businesses that operate during the day typically see the strongest returns, because they use solar power as it is generated rather than exporting it. We will model your expected savings as part of your free assessment.
Most commercial installations are completed within days once consents and grid approval are in place. We schedule work to minimise disruption to your operations, and our team manages the full consent and grid application process for you.
Yes. New Zealand’s major banks offer green business lending for solar and energy efficiency upgrades. The ANZ Business Green Loan offers a discounted floating rate on amounts up to $3 million, the ASB Business Sustainability Loan covers projects from $25,000 to $2 million, and BNZ Green Business Loans help fund renewable energy projects including solar. Ask us about finance when you request your estimate and we can provide the documentation your bank requires.
That comes down to your site and energy profile. Contact the French Electrical team for a free site assessment. We will review your power bills, roof space, and usage patterns and recommend the right system size for your business.
