For Everyday Aussies
Whether you're mid-renovation, preparing for an EV or simply looking to reduce your electricity costs, we design your home solar system around how your household actually uses energy.
Every home uses energy differently. Our SAA-accredited engineers look at your electricity usage, roof space and future plans, whether that is a battery, an EV or a growing family, to size a system that fits how you actually use power.
SAA-ENGINEERED INSTALLS
Battery and EV-ready from day one.
We size your home solar system around your actual energy needs. If a smaller system fits your roof and your habits, that's the system we'll quote. We'd rather under-sell than oversize.
A real engineer designs the system on your roof, and stays the contact when you have questions.
Every line item explained: panels, inverter, racking, rebate, payback. No mystery boxes.

A solar power system for a home is four decisions, not one purchase. Here is how we make each of them, and where to read further if you want the long version.
Most Australian homes land somewhere between 6.6kW and 13kW. The right number of panels comes out of your last four bills and the usable pitch, shading and orientation of your roof, not a package deal.
What size solar system do I need?The inverter is the part of a home solar system that does the converting, the monitoring and, eventually, the failing. We pick brands with Australian service presence rather than the cheapest unit that clears the quote.
Comparing solar invertersEvery design we draw leaves room for installing a solar battery later. If the payback stacks up today we will show you the curve; if it does not, we wire for it and leave the decision open.
Is a solar battery worth it?The federal small-scale scheme runs to 2030 and comes off the price at the point of sale. You see the gross cost, the rebate and the net figure on the same page.
How the STC rebate works in NSWSolar energy at home only pays off when the system matches the load underneath it. Before we quote, we look at what your roof can carry, what your meter data says you use and when you use it, and whether an EV, a pool pump or a heat-pump hot water service is coming. If you would rather run the sums yourself first, the solar panel calculator and our guide to reading a solar quote are the two most useful places to start. Panel direction matters more than most people expect, which is why we always walk through roof orientation before settling on a layout.
No high-pressure quotes, no truck-of-the-month panels. Just four conversations, one design, one install. Here is what to expect at each stage.
A Friendly Call
We listen to what your household uses power for, before we talk products.
Read Your Bills
Four quarters of meter data tells us more than any brochure ever will.

“Paul from Guwing Green was great to deal with, had a professional approach and took the time to understand my requirements, explain all the components of the install and its capabilities, and do a thorough on-site visit to plan the installation, cable runs, inverter location etc.”

A quick rule of thumb is to multiply your current quarterly bill by 0.4. That gives you a fair starting estimate of your savings. Most households we work with cut grid spend by 30 to 40%, but we model the exact figure off your last four bills before quoting.
Is home solar power worth it?We review your household's electricity usage and your last four bills before recommending a system, so you don't have to guess. For most Australian homes it lands between 6.6kW and 13kW. A two-person household that is out all day often does better with a smaller array and a battery than with a roof full of panels.
Sizing a home solar systemA quality 6.6kW system on a straightforward single-storey roof typically lands in the mid single-digit thousands after the STC rebate, and a 10kW system meaningfully above that. Roof type, storey count, switchboard condition and distance to the meter move the number more than the panel brand does.
What solar panels cost in AustraliaSometimes yes, sometimes no. Battery economics shift fast, so we'll show you a payback curve before suggesting one, not after.
Solar battery payback periodsYes. Installing a solar battery later is straightforward when the system was designed for it, which is how we draw every home system. An AC-coupled battery can be retrofitted to almost any existing array without replacing the inverter.
How AC-coupled batteries workThe federal STC scheme runs to 2030. We claim it as a point-of-sale discount in the quote, so you don't chase paperwork later.
The STC rebate explainedYes, we include DNSP applications in all our systems.
Manufacturer warranties on panels, inverter and battery (typically 10 to 25 years) plus our own workmanship warranty on the install.
