Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Check your solar monitoring system's app or website. Compare current production to a similar sunny period from last year and look for any error codes.
Step 2
Visually inspect your panels from the ground. Look for dirt, debris, cracks, or any discoloration. Take photos.
Step 3
Inspect the inverter. Note any error messages or the status of the indicator lights. Is it on? Is it flashing red?
Step 4
Review your original installation documents. You need to know your installer's name, and the make/model of your panels and inverter to check warranty terms.
Step 5
Document the issue thoroughly. Create a log with dates, times, photos, videos, and any error codes you've found. This is your evidence.

When to Call a Professional Solar
- You notice a significant, sudden drop in energy production that simple DIY checks (like resetting a breaker) can't explain.
- You see obvious physical damage to any part of the system—panels, wiring, or the mounting hardware. Don't touch it.
- The inverter is displaying error codes you can't clear or is completely non-functional.
- You suspect an installation defect, like a roof leak. That's a workmanship warranty claim and you need to get your installer involved immediately.
- The issue requires specialized tools, any kind of electrical work, or getting up on the roof. Don't risk your safety.
- You need help navigating the warranty claim process, especially if your original installer is out of business.
Prevention Tips
- Regularly monitor your system's performance through its app. A quick glance once a month can catch problems early.
- Keep your panels clean. If they get covered in dirt, pollen, or bird droppings, clean them according to the manufacturer's instructions (usually just water and a soft brush).
- Perform periodic visual inspections from the ground. Look for loose wires, debris on the roof, or anything that looks out of place.
- Keep all your solar system documentation in a safe, accessible place. You'll need it for any warranty claim.
- Understand the three types of warranties you have (product, performance, workmanship) and how long they last. Know your rights.
- Consider a professional maintenance check every couple of years, especially after a severe weather event like a major hailstorm.
