Solar, batteries and EV chargers for Wentworthville, Pendle Hill, Girraween and Westmead — the whole 2145 postcode. Plenty of people here have been door-knocked, cold-called and offered a price that expires tonight. This page is the checklist we would want a relative to use, including on us.
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 2145 taken off. What your home actually costs depends on your roof, switchboard and connection — we confirm it in writing after a free assessment.
Just right for most family homes
Medium homes & small businesses
Larger homes & small businesses
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 2145, 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.
Rooftop solar is a twenty-five year purchase sold in a half-hour conversation, which is why the checks below matter more than the discount. Use them on every quote you receive, this one included.
CEC accreditation belongs to an individual electrician, not to a brand. Ask for the name and the accreditation of whoever will actually do the work, and which company employs them.
Panel and inverter make, model and count — not “tier one” or “premium European”. If a quote will not name what it is selling, there is nothing to compare.
A modest deposit is normal. A large one, or pressure to pay today for a price that expires tonight, is the pattern worth walking away from every time.
That is the whole test, and it costs nothing to apply. Unsolicited sales in Australia come with a cooling-off period, and anyone discouraging you from using it has told you something useful about themselves. If an offer seems remarkably cheap, ask how many kilowatts it actually is and what equipment it uses — inexpensive systems are usually small systems rather than bargains. We would rather lose a sale to a customer who checked than win one from a customer who did not.
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.
System size, panel and inverter make and model, the count, the total with the STC discount shown, what is included and what would cost extra. Warranties are listed separately, because product, performance and workmanship are three different promises — our St Clair page explains what each one actually covers.
What the three warranties coverHome 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. Someone comes and looks at the house — we do not quote a system from an aerial photo and a phone call.
A quote naming the panel and inverter models, the system size, the total price and what is excluded. If a quote will not name the equipment, it is not a quote.
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. You are told who is coming.
Your retailer updates the meter, we set up monitoring, and you get the compliance paperwork rather than being told it is in the post.
Every install below is a real Kratos job, with the suburb and month it was completed. As we finish work around Wentworthville, 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.
