What matters most to you?
This just sets what we show you front-and-centre — you'll see everything either way.
Who lives here?
More people, more hot water, washing and screens. This sets your baseline.
Electric cars?
Each EV adds extra load to your home. We'll maximise the amount of charging that happens from solar — for free kms.
The big loads
These loads are the biggest factors in sizing your solar and battery — think about how you use them across summer.
When do you use power?
Solar only pays while the sun's up. Power you use after dark is what the battery covers — more evening usage means a bigger battery bank for the evening peak.
Your supply
Single phase or three phase changes the type of solar and battery inverter we select, but don't worry if you aren't sure. We'll confirm all of this later.

Pop your details in and Matt will be in touch — no obligation, and we confirm everything on a site visit.

/day
Indicative sizing and payback only — not a quote. Built from typical SEQ figures — Brisbane solar generates about 4 kWh a day per kW of panels — plus current grid and feed-in rates, and capped by your supply. Real figures depend on your appliances, habits, roof orientation, shading and tariff; Matt confirms everything on site with your actual bills.

Local installer, not a sales company
I'm Matt — the person who designs your system, does the install, and answers the phone if something's not right. High Energy is a small, focused operation based in West End, Brisbane. We don't do door-knocking — our standards are what get you the right result, and we won't sell you something you don't need.
We're specialists in solar, batteries, off-grid and EV across SEQ. Every system is modelled against your actual energy usage and roof layout — not a one-size-fits-all catalogue quote.
That means you get a system sized correctly from day one, with the right inverter, the right battery if needed, and an install that actually performs as designed.
