How to Verify If Your Solar Panels Are Functioning Properly

Solar panels are an excellent investment for reducing electricity bills and promoting environmental sustainability. However, once installed, it’s crucial to ensure they are functioning correctly to maximize their benefits. In this comprehensive guide, we will discuss various methods and tools to determine if your solar panels are working efficiently.

Understanding Solar Panel Performance

Solar panels convert sunlight into electricity through photovoltaic cells. The efficiency of this process can be influenced by several factors, including weather conditions, shading, orientation, and the cleanliness of the panels. To ensure optimal performance, it is essential to monitor and maintain your solar panel system regularly.

Monitoring Your Solar Panel System

1. Check the Inverter Display

The inverter is the heart of your solar power system, converting the DC electricity generated by the panels into AC electricity for your home. Most inverters have a display that provides real-time data on your system’s performance. Here’s how you can use it:

  • Status Lights: Many inverters have LED lights that indicate the system’s status. A green light typically means everything is functioning correctly, while red or orange lights may indicate a fault or issue.
  • Output Data: The display usually shows the amount of electricity being generated. Compare this with your system’s expected output based on weather conditions and time of year.
  • Error Codes: If there is an issue, the inverter may display an error code. Consult the inverter’s manual or contact your installer to interpret these codes.

2. Use a Solar Monitoring App

Modern solar panel systems often come with monitoring software or apps that allow you to track performance from your smartphone or computer. These apps can provide detailed insights, including:

  • Real-Time Data: View the current power output, historical data, and overall system performance.
  • Alerts and Notifications: Receive instant alerts if there is an issue with your system.
  • Energy Consumption: Some apps also monitor your home’s energy usage, helping you understand your energy consumption patterns and savings.

3. Examine Your Electricity Bills

One of the simplest ways to check if your solar panels are working is by comparing your electricity bills before and after installation. Significant reductions in your electricity bills typically indicate that your solar panels are generating power. Keep an eye on:

  • Energy Production vs. Consumption: Ensure that the energy produced by your panels matches your expected savings.
  • Utility Charges: Look for reduced utility charges due to decreased reliance on grid electricity.

Performing Physical Inspections

4. Inspect the Panels

Regularly inspecting your solar panels for physical damage or debris can prevent performance issues. Key points to check include:

  • Cleanliness: Dirt, dust, bird droppings, and leaves can reduce the efficiency of your panels. Clean your panels periodically, especially after storms or high pollen seasons.
  • Physical Damage: Look for cracks, chips, or other damage to the panels. Extreme weather conditions can sometimes cause such damage.
  • Shading: Ensure that no new obstacles, like growing trees or newly installed structures, are shading the panels.

5. Check the Connections

Loose or damaged connections can affect the performance of your solar power system. Ensure that:

  • Wiring and Cabling: All wiring and cables are intact and securely connected.
  • Mounting and Framing: The mounting system holding the panels is stable and secure.
  • Inverter Connections: The connections to and from the inverter are tight and free from corrosion.

Using Professional Services

6. Schedule Professional Maintenance

Regular professional maintenance from SolarFIX can help ensure that your solar panel system operates at peak efficiency. SolarFIX Professionals can:

  • Conduct Detailed Inspections: Check every component of your system, including panels, inverters, wiring, and mounts.
  • Perform Advanced Diagnostics: Use specialized tools to measure performance and detect any underlying issues.
  • Clean and Repair: Provide thorough cleaning and necessary repairs to keep your system running smoothly.

7. Performance Audits

A performance audit by a SolarFIX certified technician  can provide a comprehensive assessment of your solar panel system. This includes:

  • Energy Output Analysis: Comparing the actual energy output with the expected performance based on your location and system specifications.
  • System Optimization: Identifying any areas for improvement, such as better positioning or panel upgrades.

Common Issues and Solutions

8. Addressing Reduced Output

If you notice a decline in your solar panel system’s output, consider these common issues and their solutions:

  • Dirty Panels: Clean the panels to remove any obstructions.
  • Shading: Trim trees or remove any objects casting shadows on the panels.
  • System Faults: Check the inverter for error codes and consult with your installer if needed.
  • Weather Conditions: Understand that cloudy days will naturally result in lower energy production.

9. Dealing with Faulty Equipment

Occasionally, components of your solar power system may fail. Common faults include:

  • Inverter Failures: Inverters are typically the most vulnerable part of the system. If the inverter fails, it needs to be replaced or repaired.
  • Panel Degradation: Over time, solar panels may degrade, producing less electricity. Regular checks can help identify when it might be time to replace older panels.
  • Wiring Issues: Damaged or loose wiring can disrupt the flow of electricity. Regular inspections can help spot these issues early.


Ensuring that your solar panels are working efficiently involves a combination of monitoring, physical inspections, and professional maintenance. By staying proactive and attentive to your system’s needs, you can maximize the benefits of your solar investment, reduce your electricity bills, and contribute to a more sustainable environment. Ensure your solar panels are in top shape!
