Frequently asked questions
Answers to common questions about solar power, electrification, and energy efficiency.
In most Canberra homes; yes, they can.
It comes down to system size, roof space, and how you use energy day to day. We’ll
work with you to design a system that matches your household needs, and where
needed, recommend pairing it with battery storage to reduce your grid reliance even
further. Many ACT residents are already running all-electric homes with solar as the
foundation, we’re here to help you take that next step with confidence.
Yes, just at a reduced output.
Solar panels still generate electricity in overcast conditions, though less than on a
sunny day. Canberra’s high number of clear days works in your favour, and your
system is designed to account for seasonal variation. Batteries can also help smooth
out the cloudy days by storing energy for when you need it.
Around 25–30 years, and they don’t suddenly stop at the end.
Most quality panels come with 25-year performance warranties and will continue to
generate electricity long after that. The key is choosing reputable products and
installers; we help you invest in a system built to last, with clear support along the
way.
Not always, but for many ACT homes, it makes good sense.
Batteries help you store excess solar energy to use later, reducing your reliance on
the grid and protecting against rising electricity costs. With current rebates, the
payback is improving, especially if you’re a high energy user or looking to electrify
heating, hot water, or EV charging. We’ll walk you through the pros and cons for your
specific situation, not just sell you one because it’s shiny.
Yes, absolutely! We can design your system with that in mind.
Many Canberra households start with solar, then add a battery when it makes
financial or lifestyle sense (like after getting an EV or switching to all-electric
heating). We future-proof your system layout and inverter selection so you’re not
locked into a limited setup down the track.
Typically between 4 to 7 years in the ACT, sometimes even sooner.
With generous sun hours, STCs, and energy-conscious households, Canberra offers
a solid return on solar. Payback depends on your system size, energy use, and
whether you add a battery. We model all this upfront, so you have a clear picture
before making a decision.
Yes, especially in the ACT.
Through the Sustainable Household Scheme, eligible homeowners can access low-
interest loans for solar, batteries, EV chargers, and other upgrades. There are also
federal battery rebates and STCs that help reduce upfront costs. We’ll walk you
through what applies to your setup and help handle the paperwork.
They can be, and we’ll help you choose one that suits your home and your
car.
Whether you want a smart charger that syncs with your solar or something simpler,
we offer EV charger installation as part of our service. We’ll make sure your system
supports fast, efficient, and safe charging at home, and explain how to get the most
from it.
We love helping with that. It’s what we’re here for.
From solar and battery to heat pump hot water and electric vehicle charging, we’ll
help you plan and prioritise upgrades in a way that fits your budget and long-term
goals. We don’t push unnecessary tech; just practical, tailored advice so you can
move toward a fully electric lifestyle with confidence.
Only if it’s set up for backup, and we can make sure it is.
Not all batteries provide backup automatically, but we offer systems that do. We’ll
talk through which circuits matter to you (like your fridge, internet, or lights), and
design a setup that keeps essentials running during a grid outage.
Not when it’s done properly. And we mean properly.
We use certified mounting systems and experienced installers who know how to
work with Canberra’s variety of roof types, from tile to tin. A well-installed system
won’t compromise your roof’s integrity. In fact, it can offer a bit of protection to the
areas it covers. We treat every home like it’s our own.
We’re not salespeople! We’re local specialists, engineers and installers who listen.
We don’t believe in cookie-cutter quotes or pressure tactics. We take the time to
understand your energy goals, explain your options clearly, and offer systems we’d
be proud to install in our own homes. From first consult to post-install support, we’re
right here in Canberra, and we mean it when we say we care about you.
