Solar across the Shoalhaven, Illawarra and Southern Highlands. Whether you're putting on your first system, adding a battery or servicing one we didn't install, we handle the lot.

Adding a battery to an existing solar system, or installing solar and a battery together. We install Tesla, Sigenergy and Enphase.
What can we help with
Solar enquiries fall into one of three places. Pick the one that fits, and we'll take you to the right page.
Why Simmark for solar
Solar is a 25-year decision. Who installs it matters less than who's around to look after it for the next two and a half decades. We've been here since 1997, and we're set up to keep servicing what we install for the long haul.
Most solar businesses install and walk away. Simmark is set up with dedicated service technicians for ongoing maintenance, repairs and expansion.
Our installers, technicians and estimators are based in the Shoalhaven, Illawarra and Southern Highlands. You'll deal with the same people from quote to commissioning to whatever comes next.
Clean Energy Council accredited installer, fully insured electrical contractors. Required for STC rebate eligibility, and what you'd want from anyone working on your roof and switchboard.
Winaico panels, Fronius and Enphase inverters, Tesla, Sigenergy and Enphase batteries. Not the cheapest, but the ones we trust to still be working in 15 years.
When your panels are generating, your home runs off them instead of the grid. That's where the real saving is. Feed-in tariffs for the excess are a small bonus on top, not the main game any more.
A well-sized system pays back the upfront cost well within its lifetime, then keeps saving for years after that. Exactly how fast comes down to your usage and system size.
Quality panels are a decades-long investment, not a gadget you replace every few years, and they keep producing well into old age. Inverters have a shorter life and get replaced once or twice along the way. Both come with manufacturer warranties.
If a battery, an EV charger or going all-electric is on your radar, solar is the foundation the rest sits on. Sized right from the start, it covers more of your usage and leans on the grid less.
The big questions
For most well-sized homes in our region, yes. It comes down to your roof and how you use power, but the fundamentals stack up for most people. The part worth understanding before you commit is what actually drives the savings, because it's not what most people assume.
Here's the short version. The full detail (sizing, payback, feed-in tariffs and how batteries fit) lives on the solar installation page →.
Rebates explained
Australia has a federal scheme that effectively discounts the cost of installing solar. It's the most common question we get, and the most commonly misunderstood part of going solar.
Here's what you need to know.
Small-scale Technology Certificates are issued for every accredited solar install, based on system size and how long the system's expected to generate power. The scheme runs until 2030 and gradually reduces each year.
You don't claim STCs yourself or wait for a cheque. We take the discount straight off the system price upfront, so the price you see already has the rebate built in.
Simmark is an accredited STC trader. We register your system, generate the certificates and apply the rebate to your quote. You don't fill in any forms, and you don't deal with the scheme administrator.
The actual rebate value depends on your system size and the STC market price at the time you install. Your estimator will show you the exact figure on your quote, no maths required.
