Adelaide • South Australia
Adelaide's trusted family-owned solar installers
Premium rooftop solar and battery installs for South Australian homes and businesses. Over 20 years of combined experience, backed by genuine local support.
Residential Solar
Solar that pays for itself, and keeps paying.
Adelaide gets more sunshine than almost anywhere else in the country, which makes rooftop solar one of the best investments you can make in your home. A well-sized system offsets the bulk of your daytime usage and pairs neatly with a battery, EV charger or time-of-use tariff when you're ready.
Slash your power bills
Generate your own clean electricity and cut reliance on the grid. Many South Australian households see payback in 4–6 years.
Battery-ready systems
We future-proof every install so you can add a battery whenever it's right for you. No rewiring, no dramas.
25-year warranty
Tier-1 panels backed by a 25-year performance warranty and a 10-year workmanship guarantee on every install.
Federal STCs upfront
We apply the federal Small-scale Technology Certificates (a typical $2,000–$3,000+ discount) directly to your quote.
Rebates available right now
Take advantage of current federal schemes
- Federal STC rebate
- A typical $2,000–$3,000+ discount on residential solar, applied upfront by us, so you only pay the reduced price.

- Roughly 30% off qualifying battery storage, applied upfront as STCs. Rebate tapers for batteries over 14 kWh from 1 May 2026.
