How Queensland Weather Affects Solar Panels
Queensland’s sunny climate is perfect for solar energy production, but the high temperatures, salty coastal air, and intense storms can make it tough on solar panels.
In summer, Queensland’s heat increases electrical resistance in solar panels, which can lower their efficiency – this issue is particularly noticeable in coastal areas. For homes within 200 metres of the coast, salt spray can leave a residue on panels, corrode metal parts, and damage electrical connections.
Storm season brings its own challenges. Strong winds and cyclones can strain mounting systems, sometimes causing panels to loosen, while hail can crack or shatter the glass on panels.
| Weather Event | Potential Impact | Protective Measure |
|---|---|---|
| Cyclones | Panels may come loose | Cyclone-rated mounting systems |
| Hail | Cracked or broken glass | Panels with hail-resistant certification |
| Salt spray | Corrosion of components | Anti-corrosion coatings and films |
| Heat | Reduced energy output | Choose high-quality panels |
To protect your solar investment, consider these practical steps:
- Choose panels certified to the IEC 61701 standard for salt mist resistance.
- Use silicone sealants to shield electrical connections from moisture.
- Apply anti-corrosion coatings and films for added protection.
- Install panels facing north to maximise energy production.
If you’re near the coast, plan for monthly inspections and professional cleanings every 3–6 months to prevent salt buildup and corrosion.
Even with challenges like UV exposure, heat, and coastal conditions, the right system choices and regular maintenance can keep your solar panels running efficiently for years.
5 Main Solar Panel Problems and Solutions
Dirt and Debris Buildup
Dirt on solar panels can lower their efficiency by as much as 30–40%.
“Dust, dirt, pollen, and bird droppings can accumulate on your solar panels, reducing efficiency.” – Energy Matters
To clean your panels properly:
- Turn off the system before starting.
- Use deionised water and a soft brush for cleaning.
- Clean during the early morning or late evening to avoid thermal stress.
- Rinse thoroughly and let the panels air dry.
Aim to clean your panels twice a year – typically in spring and autumn. If you live in a coastal or dusty area, you might need to clean them more often. Severe weather can also cause direct damage to the panels.
Storm and Impact Damage
Severe weather events can expose weaknesses in solar panel installations. For example, in October 2023, a super-cell storm in Ipswich, Greenbank, and Springfield Lakes resulted in hail-damaged panels.
“Hail damaged solar panels are dangerous.” – All Energy HQ
Check your panels for cracks or other damage after storms. If you notice any issues, contact a professional to assess and repair them promptly.
Electrical Connection Issues
Salt spray can corrode electrical connections, leading to erratic power output, inverter error codes, or even system shutdowns. Regularly inspect and maintain these connection points to prevent problems.
Inverter Problems and Fixes
A red light on your inverter usually signals a fault.
“If all operating lights are green, this is generally a sign that everything is ok. If any red lights are showing, then it’s very likely that you have an inverter or grid fault.” – Jason Svarc, Solar and Battery Specialist
When you spot a red light, check the inverter for error codes and compare the generation figures with expected values. Document any irregularities before reaching out to a technician.
Hot Spots and PID Effects
Shading or cell damage can cause hot spots, while potential-induced degradation (PID) also lowers panel efficiency. Regular maintenance can boost energy output by 3.5%. To keep your system running smoothly:
- Use thermal imaging during inspections to detect hot spots.
- Monitor energy output patterns for irregularities.
- Resolve shading issues as soon as possible.
- Schedule yearly professional assessments to ensure peak performance.

Maintenance Schedule and Warranty Guide
Keeping your Queensland solar system in top shape requires regular upkeep, especially with the region’s challenging weather conditions. A structured maintenance plan ensures your system operates efficiently.
Monthly Checks
Use your monitoring app to track energy production. Look at inverter indicator lights to confirm normal operation, and take note of any unusual patterns or error codes.
Quarterly Inspections
Inspect your solar panels for:
- Corrosion on mounting hardware
- Visible damage or discolouration on panels
- Worn or loose wiring connections
Biannual Cleaning
Clean your panels during autumn and spring using only water and a soft broom. Avoid using solvents or harsh detergents, as they could cause water ingress and void your warranty.
Annual Maintenance
Trim nearby vegetation that might cast shade on your panels. Even minor shading can have a big impact on your system’s performance.
Professional Inspections
Book a professional inspection every three years to ensure your system is running smoothly and stays within warranty requirements. Combine these inspections with your regular cleaning and vegetation management for a thorough assessment. Always check your system right after severe weather.
