Solar, batteries and EV chargers for Charlestown, Whitebridge, Dudley, Redhead, Kahibah, Gateshead, Mount Hutton, Hillsborough and Tingira Heights — the whole 2290 postcode. Postcode 2290 runs all the way from the breaking surf at Dudley and Redhead up over the Pacific Highway ridge into Charlestown, Gateshead and Mount Hutton. That means two homes in the same postcode can face completely different salt exposure and wind loads — and many 1970s and 1980s homes here split their roof across two or three levels.
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 2290 taken off. What your home actually costs depends on your roof, switchboard and connection — we confirm it in writing after a free assessment.

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 October 2026. STC figures use postcode 2290, 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.
Postcode 2290 is unusual because it straddles the coastal ridge. Streets in Redhead, Dudley and eastern Whitebridge catch direct onshore salt aerosol and southerly gusts off the Pacific, while Kahibah, Charlestown, Gateshead and Mount Hutton sit behind the ridge where split-level roofs and tall eucalypts are the real design question.
Within the first kilometre of breaking surf at Redhead or Dudley, airborne salt settles on unwashed metal undersides. Specifying anodised aluminium rails, 316-grade stainless fasteners and sheltered inverter walls prevents premature corrosion.
Many brick-and-tile homes around Charlestown and Kahibah step down the slope with two or three smaller roof planes facing north-east and north-west. Wiring each plane to its own MPPT tracker stops a lower roof plane from dragging down an upper one.
On a complying connection with an online CSIP-AUS inverter, systems up to 30kW are generally approved for up to 10kW per phase of flexible export, compared with a 1.5kW static fallback if the inverter has no internet connection.
Most Tier-1 panels carry salt-mist certification, but many standard warranties exclude installations within a set distance of breaking surf unless specific mounting hardware and maintenance rules are followed. If your address is in Dudley, Redhead or coastal Whitebridge, ask for the racking corrosion rating and the inverter IP rating in writing on the quote.
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.
In Lake Macquarie, the retail electricity plan you stay on after installing solar changes your annual bill by hundreds of dollars. Our Cardiff page walks through flat, time-of-use and demand tariffs across the 2285 and 2290 area.
How Lake Macquarie tariffs affect solar paybackHome 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 check your roof faces, tile or metal profile, distance from the surf line, and your main switchboard.
Named panels, inverter and mounting hardware, with strings laid out around your roof levels and chimneys.
We lodge your grid-connection application and confirm your export allowance before installation.
Accredited electricians fit the racking, panels and inverter, seal all roof penetrations and commission the system.
We configure your monitoring app, hand over the compliance paperwork and walk you through daytime load shifting.
Every install below is a real Kratos job, with the suburb and month it was completed. As we finish work around Charlestown, 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.

“I am very happy to recommend Kratos Energy to anyone planning to install a solar panel and battery system at home. I found their pricing fair and affordable, and the service both before and on installation day was excellent. Thank you, Nessar and Wei.”
“Kratos Energy completed our solar system seamlessly, and we are very satisfied with the entire process and results. They offered a very reasonable price for the same products and services compared to other providers. A special mention to Nessar, who worked hard and efficiently throughout the process. Highly recommended to future customers.”
