Solar, batteries and EV chargers for Prairiewood, Greenfield Park and Wakeley. Before anyone sells you storage, it is worth knowing that most homes here already own some: an electric hot water tank is a battery, and pointing it at the middle of the day costs almost nothing.
These are estimated starting prices, not fixed quotes. Each package starts from the figure shown for a straightforward installation and already has the federal STC discount for postcode 2176 taken off. What your home actually costs depends on your roof, switchboard and connection — we confirm it in writing after a free assessment.

Anything that applies to your home is itemised in your written quote before you commit to it.
Prices start from the figures above, fully installed net payable after the federal STC rebate and including GST for metro areas (regional areas subject to freight and travel costs; T&Cs apply). Checked September 2026. STC figures use postcode 2176, 2026 deeming and an assumed $38 per certificate — the discount you receive depends on the certificate market on your installation date. Savings are modelled on typical usage and tariffs and are not a guarantee.
An electric storage tank holds a day's hot water, and heating it is one of the biggest single loads on a household bill. Where that heat comes from is a choice, and for a house with solar it is usually the wrong one by default.
The default on a controlled off-peak circuit. Cheaper than peak power, but still power you buy — and it happens when your panels are doing nothing.
The same tank, heated from your own roof instead. Usually a timer and a metering conversation with your retailer, not new plumbing.
Uses far less electricity for the same hot water and attracts its own federal certificates. We don't install them, so this is a pointer rather than a quote.
A home battery is the right answer for plenty of households, and we quote them happily. But it is worth doing the cheap thing first: a hot water tank stores roughly a day's worth of heat, it came with the house, and shifting when it heats converts exported kWh earning a few cents into kWh you would otherwise have bought. Do that, watch a few bills, and then decide whether a battery earns its keep on what is left.
Network rules change and every connection is approved on its own merits — we confirm the limit that applies to your address in writing before install day.
Home batteries attract two separate incentives. The federal Cheaper Home Batteries Program takes an estimated $3,402 off a 13.5 kWh battery, and NSW’s NSW VPP connection incentive (battery via federal program) can add more on top. Battery prices start from $4,290 fully installed after rebates (incl. GST for metro areas; regional areas subject to freight and travel costs). Already have solar? We check your inverter first — some systems take a battery as they are, others need a hybrid inverter.
Estimated federal rebate on 13.5 kWh of usable storage
NSW virtual power plant (VPP) incentive when you connect an eligible battery to a VPP, on top of the federal Cheaper Home Batteries discount. The NSW upfront battery discount ended for installs from 1 July 2025.
Size your solar for it now. Our 10kW package comes pre-wired for a battery and an EV charger, so adding one later is a small job rather than a rebuild.
We review your roof, shading, switchboard and a recent bill — and look at how your hot water is heated and when, because on most bills here it is one of the two largest items.
A quote with the panel layout, inverter and every extra itemised — no surprises later.
We lodge your grid-connection application and confirm any export limit before install day.
CEC-accredited electricians install, test and commission the system, then clean up.
Your retailer updates the meter and we set up monitoring. If your hot water is on a controlled circuit, this is the point to talk to them about moving it.
Every install below is a real Kratos job, with the suburb and month it was completed. As we finish work around Prairiewood, those projects will appear here too.

Kratos Energy’s 5 MW solar project in South Australia showcases renewable energy infrastructure at scale. Featuring ground-mounted solar arrays and dedicated electrical infrastructure, the project forms part of our commitment to developing large-scale solar opportunities across Australia. The project photographs offer a closer look at the installation—from rows of solar panels to the supporting structures, cabling and electrical equipment behind the system. Project at a Glance Project detail Overview Location South Australia Capacity 5 MW Project category Large-scale solar Installation type Ground-mounted solar photovoltaic system Featured infrastructure Solar arrays, mounting structures, electrical equipment and control panels A Closer Look at the Solar Installation The site features rows of elevated solar panels arranged across open land, with access routes between sections of the installation. Ground-mounted systems allow the array layout to be planned around the site’s terrain, available space and maintenance requirements. The photographs also show the underside of the arrays, including structural supports and cable routing. These less-visible components are an essential part of a solar installation, alongside the panels themselves. Dedicated electrical enclosures and control equipment highlight the infrastructure required to support a project of this scale. Together, the images provide a practical view of the engineering involved in a large-scale solar site. Large-Scale Solar Expertise A solar farm requires coordination across site assessment, engineering, equipment selection, construction and network requirements. Kratos Energy’s large-scale solar services cover solar farm development, engineering and construction support, grid connection coordination, and operational support. We work with landowners, investors and commercial partners to assess opportunities and progress renewable energy projects.
