Most residential solar installs are a single day. Solar + battery packages are usually 1.5–2 days. The crew arrives between 7 and 7:30am and is usually packed up by mid-afternoon on day one.
001 The quote & install
Process.
How long does an install take?
Do I need to be home during the install?
Briefly at the start (to confirm placement) and at the end (to walk you through the monitoring app). The middle of the day you don't need to be there. The power is off for approximately 30 minutes total.
How long from quote to install?
Currently around 3–5 weeks. Quote and contract take 1 week. Energex paperwork and equipment scheduling take 2–3 weeks. Install is one day.
What happens if it rains on the install day?
Light rain — we proceed. Heavy rain or storms — we reschedule, no charge, usually within a week.
How long is the quote valid?
30 days. The rebate values can move, so we re-quote if you take longer to decide.
002 Equipment & design
What goes on the roof.
Which solar panel brand should I choose?
We install Tier-1 panels only — REC, Jinko, Trina, LONGi, Q CELLS. The differences between top-tier panels are small. The differences in the install are large. Pick the installer first, then the panel.
Which battery should I choose?
It depends on whether you want whole-home backup, how much you want to spend, and whether you're adding to existing solar. We walk through this on the site visit — there's no universal best answer.
How long do solar panels last?
Tier-1 panels carry a 25-year performance warranty. Real-world life is 30+ years with gradual output decline (~0.4% per year for modern panels).
What about hail?
Modern panels are rated to withstand 25mm hail at 80km/h. SEQ storm-season hail occasionally exceeds this — your home insurance policy should cover solar panels as part of the dwelling. We can advise on policies that cover them explicitly.
Will solar damage my roof?
Installed correctly, no. We use flashed penetrations on tile and existing roof-screw fixings on Colorbond. Workmanship warranty is 10 years.
003 Rebates & finance
Money.
Do I have to apply for the rebate myself?
No. Both federal rebates are point-of-sale — we apply them as a discount on your quote. You sign the certificate assignment form on the day, we handle everything else.
What if the STC price changes between quote and install?
Cube absorbs the risk. Your quote is fixed.
Can I claim the rebate on a system I already own?
No — the rebate is generated at install time. Adding a battery to existing solar does still qualify for the battery rebate, however.
Do you offer finance?
Yes — Brighte green loans. 0% interest on systems up to $30,000 over 36 months, subject to approval. We can complete the application at the same site visit.
What's the payback period?
Solar alone: 3–5 years. Solar + battery (with current 2026 rebates): 5–7 years. A 10–13kW system on a SEQ home typically saves $2,500–$3,500 per year.
004 Warranty & after-sales
After the truck leaves.
What if something breaks in year four?
You ring our office — the same number on this site. We diagnose remotely via the monitoring portal first, and dispatch a service tech if needed. Inverter and panel claims go through the manufacturer; we project-manage them.
What's covered under workmanship warranty?
10 years on installation: roof penetrations, mounting, wiring, connectors. If a leak develops because of our install, we cover the repair to the roof as well as the panel work.
What if Cube goes out of business?
Equipment warranties are with the manufacturer, not us — they continue regardless. Workmanship warranty is backed by our QBCC home warranty insurance.
Do you do servicing for systems installed by other companies?
Yes, fee-for-service. Common job — installer went out of business or moved interstate.
