    “I have had my Deye solar battery and inverter installed by another company for over a month and have not had any meaningful help setting up my inverter from my installer or supplier. Despite not supplying my system, Dan has just spent close to an hour helping me. There are not many people who will put themselves out to help someone like that. Dan is so knowledgeable and helpful I would have no hesitation in recommending him.”

FAQ

Frequently asked
questions

The cost of a solar system depends on its size, quality of components, and installation requirements. For a typical Sunshine Coast home, prices range from $5,000 to $15,000 after government incentives. We provide detailed, transparent quotes based on your specific energy needs and property characteristics.

Most residential solar installations are completed in 1-2 days, while commercial projects may take 3-5 days depending on the system size and complexity. Before installation day, we handle all necessary paperwork, including permits and grid connection applications, which typically takes 2-4 weeks.

Batteries make sense if you use a lot of power in the evening, want backup power during outages, or want maximum energy independence. With low feed-in tariffs and the federal battery rebate (about $252 per usable kWh since 1 May 2026, explained in our solar rebate QLD guide), batteries are increasingly worthwhile. Our Sunshine Coast solar battery cost guide shows current installed prices by size, and we can analyse your usage to determine if a battery would benefit you.

Quality solar panels typically last 25-30 years and continue to produce electricity even beyond this period, though at slightly reduced efficiency. Most premium panels come with 25-year performance warranties, and inverters typically have 5-10 year warranties, which can often be extended.

The Sunshine Coast receives 5.2-5.8 peak sun hours daily - among Australia's best solar resources. Our subtropical climate, minimal air pollution, and excellent grid infrastructure make it perfect for solar. Most homes see 30-40% better solar production than southern capitals.
