Estimates use 4.1 kWh per kW of panels per day (Sydney, CEC zone 3). Your roof's pitch, orientation and shading will shift these figures — we model your specific site before quoting.

Residential

For the home.

Solar panels installed on a tiled residential roof in Sydney.
Residential
6.6kW

Small to medium homes · 1–4 people

The most common system in Australia, and for good reason. A 6.6kW array pairs with a 5kW inverter to make the most of the rebate and typically covers the daytime load of an average household with room to spare.

Our best-value residential package. This is a full-service job: we review your actual energy usage, look at when you draw power, and size the array around how your household really runs rather than a number off a price list.

Commercial & industrial

For the business.

Commercial solar works because your load and the sun peak at the same time. Every kilowatt-hour you generate at 1pm is one you don't buy at your highest tariff. We install with CEC-accredited crews and flexible mounting for tin, tile and Klip-Lok.

Commercial
20kW

Small business & warehouse

Offsets daytime load where it costs most — during business hours, when your tariff is highest.

Bigger than 50kW?

We also design industrial systems beyond the standard packages — multiple arrays, three-phase, and staged commissioning. Send us your roof plan and twelve months of consumption data and we'll model it properly.

Every package

What you get, whichever size you pick.

30-year panel warranty

Linear output warranty on Tier 1 modules, backed by manufacturers with Australian support.

Online monitoring

Watch production and consumption in real time from your phone. We set it up before we leave.

Rebate handled

STCs are deducted from your quoted price up front — you never pay it and claim it back later.

CEC-accredited install

Licensed electricians, compliant workmanship, and the electrical certificate supplied on completion.

Battery-ready

Residential systems are wired so adding storage later is straightforward, not a rebuild.

Finance options

Spread the cost through our lending partners. Terms come from the lender — we'll walk you through them.

No obligation

Not sure which size fits?

Send through your last power bill. We'll model your usage against your roof and come back with the size that actually pays — not the biggest one we can sell you.
