Solar, batteries and EV chargers for Woy Woy, Blackwall, Koolewong, Tascott, Horsfield Bay, Phegans Bay, Woy Woy Bay, Pearl Beach and Patonga — the whole 2256 postcode. Postcode 2256 splits into two completely different solar jobs: the dead-flat peninsula streets of Woy Woy and Blackwall with wide sky views and older cottage roofs, and the steep, wooded waterfront blocks of Koolewong, Tascott, Horsfield Bay and Woy Woy Bay where the western ridge takes the afternoon sun early.
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 2256 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 October 2026. STC figures use postcode 2256, 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.
Drive five minutes from Woy Woy station to Koolewong or Horsfield Bay and everything about a solar installation changes. On the flat sandy peninsula, there is almost no terrain shading at all — the question is the age of the roof and switchboard. Along the western shore of Brisbane Water, houses sit right below the bushland escarpment.
Around Woy Woy and Blackwall, many cottages date from the post-war decades. Metal and sound tile roofs are ideal for solar with wide-open northern sky, while any original asbestos-cement (fibro) roof sheeting cannot be drilled and must be replaced or bypassed using a newer garage or shed roof.
In Koolewong, Tascott, Horsfield Bay and Phegans Bay, the steep ridge to the west blocks late-afternoon sun, especially in winter. Prioritising north and east roof faces — and storing morning surplus in a battery — captures the sun while it is over the water.
In Pearl Beach, Patonga and the bay villages, part-time holiday houses that turn off the Wi-Fi router when empty can drop from a 10kW flexible export limit down to a 1.5kW static limit. Keeping a basic internet connection live protects your export allowance.
Standard Sydney advice says to put panels on the west roof for late-afternoon power. Along Koolewong, Tascott and Woy Woy Bay, the ridge behind the railway line and water puts the house in shadow while the sun is still well above the horizon in winter. Putting your panels on the north and east faces where the sky is open over Brisbane Water — and letting a home battery or daytime hot-water timer soak up the morning generation — produces far more usable kilowatt-hours over the year.
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.
If your house in Woy Woy or Blackwall dates from before the late 1980s and you are unsure what the roof or eaves are made of, our Gosford page explains how we handle older fibro roofs and when a shed or re-roof is the right first step.
Older roofs, asbestos cement and solar options in 2250 and 2256Home 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 inspect your roof material, switchboard and — if you are along the bays — the ridge line behind your house.

We lodge your grid-connection application and confirm your export limit before install day.
Licensed electricians install, test and commission the array, leaving your roof watertight and the site clean.
We set up your monitoring app and confirm your export settings and warranty paperwork.
Every install below is a real Kratos job, with the suburb and month it was completed. As we finish work around Woy Woy, 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.
