Has your solar energy output dropped recently? You’re not alone. Many solar system owners notice dips in performance but don’t know where to start troubleshooting. The good news is you can perform three quick checks in just 10 minutes to spot common issues and decide what to do next. This post will guide you through these simple steps, helping you save meter screenshots, run self-tests, and understand when it’s time to call a professional.

Check 1: Review Your Solar Meter or Monitoring App
The first step is to check your solar meter or monitoring app. Most modern solar systems come with a digital monitoring tool that tracks energy production in real time. Here’s what to look for:
Compare current output to historical data. Look at the same time and day from previous weeks or months. A sudden drop could indicate a problem.
Check for error messages or warnings. Some systems display alerts if there’s a fault.
Save screenshots or export data. This helps you track changes over time and provides useful information if you need to contact support.
Example: If your system usually produces 5 kW at noon on a sunny day but now shows 3 kW, that’s a clear sign to investigate further.
Check 2: Inspect Solar Panels and Wiring Visually
Next, take a quick walk around your solar panels and check for obvious issues. This visual inspection can reveal common problems that reduce performance:
Look for dirt, dust, or debris. Even a thin layer of dust can reduce output by up to 25%. Clean panels gently with water if needed.
Check for shading. New tree growth, nearby construction, or seasonal changes might cast shadows on panels.
Inspect wiring and connections. Loose or damaged cables can cause power loss or system faults.
Look for physical damage. Cracks, broken glass, or corrosion can affect panel efficiency.
Example: A branch shading part of your array in the afternoon can reduce output significantly. Removing the branch or trimming trees can restore performance.
Check 3: Run System Self-Tests and Reset if Needed
Many solar inverters and monitoring systems include built-in self-tests to diagnose issues. Running these tests can help identify faults without needing specialized tools.
Access the inverter menu or app. Follow the manufacturer’s instructions to start a self-test.
Note any error codes or messages. Look up codes in your system manual or online.
Perform a system reset if recommended. Sometimes a simple reboot clears temporary faults.
Record test results. Keep a log for future reference or when contacting technical support.
Example: A self-test might reveal a faulty string of panels or inverter malfunction. Early detection can prevent bigger problems.
