About Sunstak

Meet the Energy Geeks

An Energy Geek knows energy, gets excited about it and loves sharing that passion. That’s us. We care about the details, take pride in our work and are hard to stop once you get us started.

Ownership

The people you’ll be dealing with

You’ll speak directly with the Energy Geek who designs your system. The same team prepares your quote, orders your equipment and answers the phone after installation.

How we work

From your first energy bill to switching on your system, we guide you through every step.

Share your energy bills
Send us a summer bill and a winter bill, and tell us when you use the most energy. This helps us design around your household.
Talk to an Energy Geek
During a home visit or phone consultation, we discuss your goals and review your roof, switchboard and meter.
See your system design
Our engineer designs your system in house. You’ll see where the equipment will go and understand why it suits your home.
Review your quote
Your quote clearly lists equipment, model numbers, inclusions and exclusions. Take your time to review it. We only order once you approve.
Get ready for installation
We explain what to expect on the day, including any planned power interruptions and how long they should last.
Enjoy ongoing support
We get your system running and set up your monitoring app. For questions, service or warranty help, the same team is here after installation.
