Your solar energy system is built to last—but like any home investment, it needs regular care to keep performing at its best. Whether you’ve had your solar panels for a few months or several years, knowing when to schedule a system check-up can save you from bigger headaches (and bills) down the road. Here are some common signs your solar system might need attention—and what you can do about it.
1. Your Energy Bills Are Higher Than Usual
If your electricity bill has started creeping up despite no changes in your energy habits, your solar system could be underperforming. This might be caused by:
-
Dirty or damaged panels
-
Shading from growing trees or new obstructions
-
Inverter issues
What to do:
Compare your latest bills with previous ones, and check your solar monitoring app (if available). A sudden drop in production is worth investigating with a professional.
2. Your Solar Monitoring System Shows Reduced Output
Many systems come with a monitoring app or web portal that tracks energy production. If your system’s output is lower than expected—or it’s showing irregular patterns—it may be time for a check-up.
What to do:
Look for consistent trends rather than one-off dips (like during cloudy days). If production is consistently low, call a technician.
3. Dirt, Debris, or Snow is Covering Your Panels
This one’s easy to spot. A layer of dirt, bird droppings, leaves, or snow can block sunlight and reduce your system’s efficiency. Panels are typically self-cleaning when it rains, but build-up can still happen, especially if you live in a dry or tree-heavy area.
What to do:
Visually inspect your panels regularly. Schedule a professional cleaning if you notice visible grime or if rain isn’t doing the trick.
4. You Notice Physical Damage to Panels or Wiring
Cracks, discoloration, or loose wiring can all be signs of wear or damage from weather, pests, or accidents. Even micro-cracks invisible to the naked eye can affect panel performance over time.
What to do:
Never try to repair panels yourself. Call a certified solar technician to safely assess and fix the issue.
5. Your Inverter Lights Are Blinking or Off
The inverter is the heart of your system—converting solar energy into usable electricity. Most inverters have indicator lights. A green light usually means everything is working, while red or blinking lights signal a problem.
What to do:
Check the inverter’s manual or online guide. If the issue persists, contact your solar provider for diagnostics.
6. It’s Been Over a Year Since Your Last Inspection
Even if everything seems fine, annual maintenance is essential for keeping your system in top shape. A regular inspection can detect minor issues before they turn into expensive repairs.
What to do:
Book a professional system check-up at least once a year. Many providers, including Consumers Energy Services, offer affordable maintenance packages.
Don’t Wait—Protect Your Solar Investment
A solar energy system is a smart, sustainable investment—but like your car or HVAC system, it needs a little TLC. Spotting signs early and scheduling timely check-ups can keep your panels producing power efficiently for years to come.
