FAQ
Common 13.3kW solar questions, answered
Is 13.3kW enough for my Sunshine Coast home?
It suits homes wanting backup power and energy independence — larger households, home businesses, or anyone planning a battery to ride out blackouts. If you’re after standard daytime bill offset without backup, 6.6kW or 10.45kW is usually enough — we size to your actual bill and goals.
Why 28 panels for a 13.3kW system?
28 × 475W panels totals 13.3kW of panel capacity, paired with a 10kW inverter — the inverter is sized slightly below panel capacity because panels rarely hit their full rating at once, which is standard industry practice.
How long does installation take?
Most 13.3kW residential installs are completed in one day, with grid connection approval and meter changeover typically finalised within 3-4 weeks after.
What happens on a cloudy day?
Panels still generate on overcast days, typically 10–25% of clear-sky output. Your inverter and any grid connection ensure you’re never without power.
Do you service my suburb?
Our core service area runs from Caboolture to Gympie, extending out to Brisbane and the Sunshine Coast hinterland. Not sure if you’re covered? Ask when you request your quote.
