It depends on system size, roof type and the components you choose. Government incentives (STCs) reduce the upfront price significantly, and we apply them directly to your quote. Book a free assessment for a fixed, written price.
If you use most of your power in the evening, have a low feed-in tariff, or want blackout backup, a battery can make a big difference. Battery rebates may also apply. We'll model it on your actual usage so you can decide with real numbers.
Most residential systems are installed in a single day. Larger homes, battery add-ons and commercial projects can take a few days. We handle network approvals and metering paperwork for you.
Panels typically carry a 25-year performance warranty, inverters 5–10 years, and batteries around 10 years, depending on the brand. On top of that, we provide our own 10-year workmanship warranty.
