You’ve made the smart move to go solar—congrats! But like any major investment, your solar system needs a little care to keep performing at its best. The good news? Solar panels are low-maintenance by design. Still, with a bit of regular attention, you can ensure they’re operating at peak efficiency and delivering maximum savings year after year. residential solar system brisbane
Here’s how to keep your solar system shining bright:
1. Keep Them Clean (But Safely!)
Dirt, dust, leaves, bird droppings, and even coastal salt spray can reduce panel performance over time. Thankfully, cleaning them is simple:
How often? Once or twice a year is usually enough.
How to clean? Use a soft brush or sponge with a hose. Avoid harsh chemicals or pressure washers.
Safety tip: If your roof is steep or hard to access, always hire a professional solar cleaning service—your safety comes first.
If you live in an area with high pollen, heavy dust, or lots of trees, you might want to check them more often.
2. Watch for Shade and Growth
Even a little bit of shade—caused by trees, antennas, or roof structures—can significantly reduce output. Make it a habit to:
Trim back trees or plants that may begin casting shadows
Check for new structures or objects blocking sunlight over time
The goal is to keep your panels soaking up as much sun as possible, all day long.
3. Monitor System Performance
Most modern systems come with an app or online portal where you can track production. Look for:
Sudden drops in energy output
Alerts from your inverter
Patterns that don’t match typical sunny days
If your system isn’t producing as expected, it could be a sign that something needs attention.
4. Inspect the Hardware Annually
While the panels themselves are built to last 25+ years, other components like wiring, inverters, and mounting brackets should be inspected periodically. Once a year, visually check for:
Loose wiring or corrosion
Damaged panels (especially after storms)
Inverter error lights or messages
If you spot anything unusual, contact your installer or a licensed solar technician.
5. Schedule a Professional Service Every Few Years
Even with DIY checks, a professional inspection every 2–3 years is a smart move. They’ll:
Clean panels thoroughly
Test performance and electrical connections
Check the inverter, isolators, and safety systems
This helps catch minor issues before they become expensive problems.
6. Know Your Warranties
Most solar panels come with performance warranties (usually 25 years) and product warranties (10–15 years). Inverters typically carry 5–10 year warranties. Keep a copy of all paperwork and know who to call if something goes wrong.
Bonus Tip:
If your panels were installed under a government rebate, check if there are any maintenance requirements to remain eligible for future support or guarantees.
In Summary
Solar panels are incredibly reliable, but a little upkeep goes a long way:
✅ Clean them once or twice a year
✅ Keep an eye on shading
✅ Monitor your system’s output
✅ Do a visual inspection annually
✅ Get a professional check-up every few years
By staying on top of these simple steps, you’ll protect your investment and maximise your savings for decades to come.
