Solar panels are low maintenance — not zero maintenance. Australian dust, pollen, salt air, bird mess and wildfire ash all steal yield if you ignore them. This guide covers safe cleaning, monitoring checks, inverter care, wildlife issues and when to call a CEC-accredited technician, so your 25-year performance warranty has a fair chance of matching real-world output.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.
Free for homeowners. Participating installers pay MrSolar a lead fee when matched — that does not buy a higher ranking in our guides or reviews. See how we match quotes and is MrSolar legit?
Check your inverter app weekly for sudden generation drops on clear days. Compare specific yield across seasons rather than obsessing over a single winter afternoon in Hobart or Melbourne. Persistent string imbalance, repeated fault codes or communications loss deserve a technician visit. Catching a failed isolator early prevents months of silent underperformance. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots. Photograph your switchboard and roof planes before quoting day to cut variation risk.
Many roofs are not DIY-safe. If you clean, use soft water and non-abrasive tools; avoid harsh chemicals and high-pressure blasts that drive water under glass. Coastal Perth and Sydney salt film differs from inland NSW dust. Bird-proofing may beat endless washing. When in doubt, hire roof-safe cleaning services that understand live DC isolators.

Keep inverter ventilation clear — hot Australian garages cook electronics. Note firmware update policies with your installer. Test that monitoring portals still log in after router changes. RCD trips and burning smells are stop-work events: shut down via the documented procedure and call a licensed electrician. Do not “just reset” forever. A site assessment with photos, stringing plan and shade notes beats brochure layouts; mismatched orientations need separate MPPTs or module-level electronics.

Nesting birds under arrays are a classic Australian nuisance; professional exclusion is safer than garden hoses. Trees that were tiny at install can shade strings five years later — prune thoughtfully or accept yield loss. Micro-cracks from hail or poor handling may only show in thermal imaging. After severe storms, book an inspection before lodging insurance guesses.

If you added storage with Cheaper Home Batteries Program support (~$372/kWh usable since 1 July 2025), follow manufacturer guidance on firmware, operating modes and enclosure clearances. Watch cycle behaviour monthly. A battery that never discharges may be misconfigured rather than “saving itself”. Size usable kWh to your 4pm–9pm consumption, confirm CEC listing, and keep federal (~$372/kWh usable) and any state battery support itemised — never as one mystery “government discount”.

Store CEC compliance docs, STC forms, serial photos and warranties together. If your original installer disappears, MrSolar can help you find CEC-accredited service providers. Scheduled inspections every few years are cheap insurance compared with undiscovered downtime.
