7 Signs Your Solar Panels Need Repair (And How to Fix Them Fast)

Noticing your solar panels acting up? Maybe the numbers are weird, the system’s making strange noises, or something just seems… off. No worries! Let’s walk through what to look for, how to do a quick check yourself, and when to call in a pro.

1. Uneven or Decreasing Power Output

What it looks like:

– Some panels are producing less than others.

– Your overall solar output is trending down, even on sunny days.

Quick Checks:

– Compare today’s numbers to your usual baseline.

– Any new trees, buildings, or objects casting shade?

– Check for dirt or leaves on the panels.

– Is anything loose or corroded on the wiring, at least what you can safely see?

– Peek at the inverter: Any error lights or weird codes?

Fixes:

– Clean off panels if they look dirty (just water and a soft cloth).

– Trim any branches that are suddenly blocking the sun.

– Still not right? Call a pro. You might have a wiring or equipment issue that needs expert eyes. If you’re located in Queensland, consider contacting Solarfix services Gold Coast and Brisbane for expert assistance.

2. Visible Damage to Panels or the Inverter

Panel Problems To Spot

– Visible cracks or chips

– Discoloration or odd patterns on cells

– Lifted corners or broken glass

What to do:

– Use binoculars or take photos from the ground.

– DO NOT climb on the roof unless you’re trained and safe.

– See anything scary? Time for a professional repair—DIY fixes can make it worse.

Inverter Issues

– Sudden dips in production

– The inverter shuts down or shows error messages

– You see scorch marks, loose wires, or a burnt smell

Quick Fixes:

– Double-check cables and vents—sometimes a simple reset works.

– Replace or clean cooling fans if it’s running hot.

– Persistent problems? Jot down the error codes and call a licensed tech.

3. Rapid Spikes or Drops in Energy Generation

Sudden Drops

– Output falls off a cliff while the weather is great.

Check:

– New shadows? Growing trees, new construction, etc.

– Dirty panels? Bird mess? Clean them gently.

– Inverter showing a red or blinking light? Try a reset.

– Any loose wires?

Still dropping? Time for a technician.

Weird Spikes

– Output jumps way up for no reason (sounds nice, but it’s not normal).

What to do:

– Double-check for loose or damaged wires.

– Make sure no one’s fiddling with the system settings.

– Compare to last week’s weather—sometimes it’s just a freak sunny day.

– Ongoing weirdness = call in the pros.

Inconsistent Patterns

– Output jumps all over the place instead of following a smooth curve.

DIY Steps:

– Clean panels, check for shade.

– Look for loose mounts.

– Review inverter logs for repeating errors.

Not consistent again soon? Book a pro inspection.

4. Inverter Alerts or Fault Codes

If your inverter is trying to tell you something:

– Note the code/message.

– Check your manual or app for what it means.

– Some faults are just a blip—reset and watch.

– If the same code keeps coming back, something’s up.

What you can do:

– Record the alert, system conditions, and when it happened.

– Double-check wiring at the inverter (don’t touch if you’re unsure!).

– If resets don’t help, call support or a technician.

5. Abnormal Noises or Odors

Hear or smell something weird?

– Buzzing, humming, or clattering: Might be a loose wire or failing fan.

– Burning, plastic, or ozone smell: Could be serious—shut down the system!

Safety Steps:

– Turn off the main disconnect.

– Look (don’t touch) for melted wires or scorch marks.

– If in doubt, get a professional ASAP. Better safe than sorry.

6. Frequent Tripping or Electrical Disconnects

Signs:

– System shuts off randomly.

– You’re resetting breakers more than making coffee.

DIY Checklist:

– Note when/why it trips.

– Look for obvious burnt wires or loose terminals (from a safe distance).

– Make sure breakers aren’t old or mismatched.

Still tripping? Get a licensed technician to check deeper electrical issues.

7. Debris, Snow, or Shading on Panels

What you’ll notice:

– Output drops after a storm or heavy wind.

– You see leaves, snow, or bird droppings.

What to do:

– Gently clean off panels (never scrape!).

– Trim back any new tree growth.

– Use an app to check for changing shadow patterns throughout the year.

Tip: If you keep having the same issue, consider a regular cleaning service or a pro checkup.

When In Doubt, Call a Pro!

If you’ve tried the quick checks and things still aren’t right, don’t risk your safety or your system’s warranty. A licensed solar technician can:

– Diagnose wiring and component issues

– Test for hidden faults

– Restore your system to peak efficiency

Bottom line: Stay alert for these signs, do simple checks, and don’t let issues linger. Fast fixes keep your solar savings safe and your system running strong!
