Big roofs, big households and an EV in the garage. We design Berwick systems around all of it, from the builder-fitted solar that is now too small to full arrays with 24 to 40kWh of storage. Installed by our own A-Grade electricians.
Berwick has more written-up Powerband installs than any other suburb, and they follow a pattern. The house is a four or five bedroom family home in one of the estates, often double storey, with a large roof and a modern switchboard. It either has no solar or a small system that came with the house. And the household uses a lot of power: ducted heating and cooling, a pool or spa in some, and more and more often an EV.
That is why Berwick systems are large. Our installs here run from 8kW to 19.68kW, and most pair the array with 24 to 40kWh of battery. A multi-face roof with a second storey takes more design than a simple gable, so we map every face for shading and morning or afternoon output before we count panels. Several streets have three-phase supply, which changes the inverter and what can be exported.
The newest streets in Berwick were built without a gas connection, so the whole house already runs on electricity and a battery earns its keep from the first night. In the older estates such as Timbarra and Brentwood Park the gas heater and hot water are next in line, and we size the solar for the day they go. More on our work across Berwick.
The four jobs that make up nearly every Berwick solar quote.
Jinko Tiger Neo panels across every useful face of the roof. On Berwick's two-storey homes that often means four or five faces, each wired so that morning shade on one does not drag the others down.
Sigenergy SigenStor in three to five modules is the most common Berwick battery, with GoodWe, Tesla Powerwall and Sungrow also fitted. Sited in the garage beside the switchboard, sized to carry a family through the evening and into the morning.
A 7kW Sigenergy, Tesla Wall Connector or GoodWe charger wired alongside the battery and inverter, set to charge the car from the roof first. Most Berwick garages need only a short cable run.
The small system that came with the house is usually on the best part of the roof. We remove it and use that roof space properly, as part of one new design.
The full range is on our products page.
Tier-one panels with 25-year performance warranties, laid out for the roof faces you have.
Hybrid and string inverters, chosen so a battery can join the system now or later.
Home batteries sized to the evening peak, with backup circuits set up for outages.
Home chargers wired into the same system and set to charge from your solar first.
Every one is a real install with the full specification. The rest are in the case studies section.
41 Jinko panels on a tin roof, the largest array we have put on a Berwick home, with a Sigenergy hybrid inverter, five battery modules and a 7kW EV charger together in the garage.
23 Jinko panels, a Sigenergy hybrid inverter and three SigenStor modules beside the switchboard, enough stored power to carry the house through the evening and into the next morning.
An engineer with a young family ran the numbers first. We installed 30.6kWh of Hiconics storage with a 6kW hybrid inverter, and ducted reverse cycle in the same job, so stored solar heats the house after dark.
A larger system on a more complicated roof, so the design step does more of the work.
Roof faces, pitch and access, single or three-phase supply, the switchboard, the garage, and what the household runs.
Each face is checked for shade and output through the day. The layout and string design come before the system size.
Panels, inverter, battery, EV charger if you want one, and the after-rebate price. Staged options if you want the battery or charger later.
Two-storey access equipment, panels, inverter, battery and charger fitted by our own crew.
App monitoring, backup circuits tested, the EV charger set to solar mode and the Certificate of Electrical Safety issued.
Not every job qualifies for everything. Some of our Berwick installs used the Solar Victoria rebate and some did not, and the quote shows which applies to you.
Small-scale technology certificates apply to every eligible solar system, whatever your income or property value, and come off the price at the point of sale.
The Cheaper Home Batteries discount, around 30 percent off an approved battery with no income test. On a 24 to 40kWh battery this is the largest single saving.
For eligible owner-occupiers, on solar panels and inverters only, with eligibility limits on the household and the property. There is no Solar Victoria battery rebate or loan: both closed in 2025. We check your eligibility before quoting.
We work in Berwick most weeks, and the case studies are there for anyone to read.
Ten written-up Berwick installs, from 8kW to 19.68kW, with the owners' reviews. Ask us for one on a roof like yours.
Solar, battery, EV charger and the heating it will run are designed together, by the company that installs all four.
Large homes bring three-phase supply, multi-face roofs and height. This is our normal Berwick job, not an exception.
Solar Accreditation Australia accredited, New Energy Tech Approved Seller, with our own electricians on every roof.
Live Google reviews. Look for the Sigenergy, GoodWe and Powerwall jobs.
Anything else, call 0466 355 441. You will get an electrician, not a salesperson.
Most of our Berwick systems are between 10kW and 15kW, with larger homes going to nearly 20kW. The right size depends on your roof faces and what the household runs, especially ducted heating and cooling and an EV.
Yes. Small builder-fitted systems are common in Berwick. We usually remove it and design a full system across the roof, because the old array sits on the best face.
Berwick has both. We confirm it at the site visit, because it decides the inverter, the battery options and how much you can export to the grid.
Yes. We wire the charger into the same system and set it to charge from surplus solar first, then from the grid at off-peak times if needed.
An all-electric home uses more power in the evening than a gas one, because heating, hot water and cooking are all on the meter. That is the load a battery is built to cover, so the payback is usually better.
It depends on household income, property value and whether the address has claimed before. It only covers solar panels and inverters. The federal STCs and battery discount apply regardless, and we work out all of it before you sign.
A site visit, then a written quote with the roof layout, system size, battery, optional EV charger and the after-rebate price. No obligation.
