Solar & energy / Otago
Our Dunedin solar electricians start with the power you use. A workshop running machinery during the day has a different brief from a home charging a car overnight. Send a bill and tell us what you’d like the system to cover.

Solar assessment / First step
Your bill shows what you bought and what it cost. Tell us when you use the most power and whether backup matters. We’ll explain what we can tell from the bill, and whether half-hourly usage or a site visit would help before we price anything.
Upload my power bill A PDF, photo or retailer usage file is fine. You can cover bank and account details.No bill handy?
Choose your usual monthly spend in NZ dollars, or leave it unsure. This gives us context for a conversation. A winter bill alone won’t tell us how much solar you’d use in summer.
Ask a question by emailSolar on the land
A ground array can sit closer to the useful sun or leave a working roof free. The land, winter shade and cable route back to the switchboard all affect the design.
Explore ground-mounted solar →Planning a system
When are the workshop doors open? When does the hot water heat? If you have a recent bill or half-hourly usage from your retailer, we can look at how much generation you’re likely to use on site. We also check shading and space on the roof or ground.
If you already have panels, send us the inverter model and a recent power bill. We’ll check what can work with your system. If backup matters, tell us what needs to stay on during a cut and for how long.
A pump starting up and a fridge running overnight make different demands on a system. We work through the equipment you use, winter demand and any generator you have before sizing the panels and storage.

Operating hours, seasonal demand and separate meters can change the case for solar.
Battery storage & backup
Compare storing surplus solar, backing up essential loads and managing site demand.
From our installation work
The roof is one option. Open ground can also give an array a clear view of the sun. Before recommending a position, we look at shading, access and the cable route back to the switchboard.

Questions, answered
No. For a grid-connected site, we can compare panels alone with adding storage. The useful starting point is when you use power and how much generation you are likely to use on site.
Backup needs to be designed for the loads you want to keep running. Tell us which ones matter and we’ll check what your inverter, battery and installation can support.
Yes. A current bill and interval data if available help us compare the load with expected generation. Include regular days closed, seasonal changes and planned equipment.
Existing solar
If the app has gone offline, tell us what you see and whether the inverter shows a fault. For low output, include when it started and whether shading or your power use has changed. Leave covers closed.
Getting started
Send the suburb or rural location, a recent power bill if you have one, and a photo of the roof or ground you have in mind. If you’re looking at backup or charging, let us know what you want to run.
