Let’s face it — you invested in solar because you wanted to save money, reduce your carbon footprint, and enjoy a reliable source of energy. But what happens when things don’t go according to plan? Maybe your system isn’t producing as much power, or you’ve noticed a cracked panel or a weird alert on your inverter.
Before panic sets in, take a deep breath. Most solar issues are fixable — and if you catch them early, they don’t have to cost a fortune.
At Saguaro Solar, we specialize in solar panel repair and maintenance. Whether you’re dealing with a broken solar panel, mysterious drops in output, or frustrating inverter glitches, we’re here to help you understand what’s happening and what you can do about it.
Let’s walk through the most common solar panel problems, how to spot them, and the smartest way to fix them — without breaking the bank.
1. How to Tell If Your Solar Panel Isn’t Working
The first step in solving a problem is knowing one exists. Keep an eye out for these red flags:
- Your energy bills suddenly spike
- The inverter is showing error codes
- Your monitoring app shows inconsistent performance
- Obvious physical damage (like cracks or discoloration)
- Your system shuts off unexpectedly — a sign of solar power failure
If you’re experiencing any of these issues, it’s time for solar panel troubleshooting or a professional solar panel inspection.
2. Common Solar Panel Problems (And What Causes Them)
Let’s look at what typically goes wrong and how you can catch it early:
✅ Damaged Solar Cells
Cracks, hot spots, or delamination can occur due to hail, debris, or poor installation. These damaged areas reduce your system’s efficiency and can eventually lead to full panel failure.
✅ Solar Panel Wiring Issues
Loose connections, corroded terminals, or gnawed wires (thanks, squirrels!) can interrupt power flow. This is often the culprit when your solar panel is not working but still looks fine.
✅ Solar Inverter Failure
Your inverter is the heart of your system. If it’s showing warning lights or errors, you might need a solar inverter repair — or a full replacement, depending on the age and warranty coverage.
✅ Dirty or Shaded Panels
This one’s simple: dust, pollen, leaves, or bird droppings can reduce output by up to 25%. A regular solar panel cleaning service can help avoid this.
3. DIY Solar Panel Repair: What You Can (and Can’t) Do
We get it — you’re handy. And while we love a good DIY project, some things are best left to the professionals. That said, there are a few things you can safely try at home.
You Can:
- Check the inverter display or app for error codes
- Visually inspect panels from the ground (no ladders, please!)
- Gently rinse panels with a garden hose to remove dust (early morning or late evening is best)
- Review your system’s performance in your monitoring dashboard
You Shouldn’t:
- Climb on the roof or walk on panels
- Try to fix solar panel wiring issues without training
- Open the inverter casing
- Attempt to repair damaged solar cells or cracked panels on your own
