How solar works
1
Solar panels sit on your roof and capture energy from the sun. That energy gets converted into electricity your home uses in real time. When you're generating more than you need — say, on a sunny afternoon while you're at work — the surplus gets fed back into the grid and your power company credits you for it.
The result? Lower power bills, and a home that's doing more with sunshine than you'd ever thought possible.
What the process looks like
2
One thing that surprises most people is that the panels themselves go up in a day. The weeks in between are mostly approvals and admin — your lines company needs to give the green light before we can connect to the grid, and your power company needs to swap out your meter so it can measure electricity flowing in both directions. We manage all of that for you.
What we install

Every home is different, so we design each system to suit yours. We'll look at your roof orientation, your power usage, and your budget, then recommend the right combination of panels, inverter, and if it makes sense for you battery storage.
We handle everything from the design through to the final sign-off, so you're not left chasing paperwork or trying to figure out who does what.

What Our Clients Are Saying
“We can’t recommend Peter at Powermac highly enough. He handled the wiring for our new build and later came back to install our solar system — professional, reliable, timely, and a pleasure to work with on both jobs. Our power bills are much cheaper now that we have solar. Will definitely be using him again. Since then, my parents have also used him for their solar install and were equally impressed.”
Amy Oldfield, Mapua NZWe couldn’t be happier with our experience working with Pete from Powermac on the solar installation for our new home. From our first conversation, Pete was friendly, knowledgeable, and genuinely passionate about helping us find the best solution for our home.
He made the whole process easy to understand, kept us well informed throughout, and was always happy to answer our questions. The installation was completed to a very high standard, and everything was organised professionally and efficiently.
It’s refreshing to work with someone who takes so much pride in their work and genuinely cares about their customers. We absolutely love our new solar system and have complete confidence that we made the right choice with Powermac.
We highly recommend Pete and the team to anyone thinking about installing solar. Thanks again for making the whole experience such a positive one!
