Are your solar panels functioning as they should? Many homeowners who have invested in solar power find themselves asking this question at some point. Whether you’ve noticed a sudden spike in your electricity bill or can’t tell if the energy production is up to par, it’s crucial to know how to check the health of your solar panels.

One key fact is that indicator lights on your inverter play a significant role; a green light usually means all systems are go, while orange or red could signal trouble.

This article will guide you through simple ways to determine if your solar panels are working correctly. We’ll cover everything from checking your inverter and reading the meter to understanding changes in your electric bill and looking for obstructions that could impact performance.

After reading, you’ll be equipped with the knowledge needed to ensure you’re getting the most out of your investment—or when it might be time to call for help. Stay powered!

Indicators of Functioning Solar Panels

Knowing if your solar panels are working right is key. Look at specific signals that show they’re doing their job well.

Inspecting Your Solar Inverter

To ensure your solar panels work correctly, checking the solar inverter is crucial. This device converts DC power from your panels into AC power for your home.

  1. Look at your inverter for any physical damage. Cracks or missing parts can indicate problems.
  2. Make sure all connections are tight. Loose wires can lead to malfunctions.
  3. Notice the lights on the inverter. Flashing red lights often signals an issue.
  4. If the inverter stops working, it may seem like your solar panels are not functioning.

Keeping these points in mind helps maintain your solar energy system’s efficiency and longevity.

Reading Your Solar Meter

After checking your solar inverter, the next step is to read your solar meter. Your solar meter provides vital information about how much power your photovoltaic (PV) system produces. Here’s how you can do that effectively:

  1. Find your solar meter: It’s usually located next to your electric meter. Solar PV systems often have dedicated meters.
  2. Look for a digital display: Most solar meters have a digital screen showing kilowatt hours (kWh) generated.
  3. Check the numbers during sunlight: For accurate readings, examine your meter on a sunny day. This shows you how much energy your panels produce at peak performance.
  4. Note down daily readings: Keep track of the power generated each day to notice any significant changes over time.
  5. Compare with previous months: Look at the kWh produced in previous months to measure performance consistency.
  6. Watch out for error messages: Some advanced meters display errors if there are issues with your system.
  7. Use an app if available: Many modern systems come with an app where you can monitor your solar production from your phone or tablet.
  8. Understand net metering displays: If you’re part of a net metering program, learn how your meter distinguishes between energy consumed and energy sent back to the grid.

Reading your solar meter regularly helps you spot any drops in efficiency early on, ensuring you get the most out of your investment in renewable energy resources.

Examining Your Electric Bill

Turning to your electric bill after checking the solar meter offers more clues about your panels. Your bill shows how much electricity you generate and use. If your solar power system is effective, you might notice lower charges from the electric company because you’re using less from the utility grid.

Look for “net energy metering” on your bill. This means you get credit when your panels produce more power than needed. A high credit suggests your solar array works well, reducing or eliminating what you owe to the electric company each month.

Checking for Any Obstructions

Solar panels need a clear path to the sun to work well. Obstructions like dirt, leaves, or shade can slow them down. Here’s how you can check for any issues:

  1. Look for Shade: Trees or buildings might cast shadows on your panels during certain times of the day. Keep an eye on your solar setup from morning to evening to note any shading issues.
  2. Inspect for Dirt and Debris: Leaves, dirt, and bird droppings can cover your solar panels. This layer blocks sunlight and reduces power production.
  3. Check After Bad Weather: Strong winds or storms can leave debris on your panels. Always inspect them after such events to ensure they are clear.
  4. Watch Out for Snow Accumulation: In winter, snow can pile up on the panels. While it usually slides off smooth surfaces, sometimes you might need to gently remove it.
  5. Search for Signs of Wear: Visual inspection is key in spotting wear or damage that could obstruct sunlight from reaching the solar cells effectively.
  6. Regular Cleaning Is Crucial: Since soiling significantly impacts efficiency, setting a schedule for regular cleaning ensures unobstructed energy production.
  7. Monitor Surrounding Vegetation: Growing trees or bushes might start shading your solar array over time. Trimming them back helps avoid this problem.
  8. Use Technology Aids: Some solar systems come with apps that help monitor performance levels in real time, alerting you to potential obstructions quickly.

Each step ensures that nothing stands between your solar panels and the sun’s rays, maintaining optimal performance throughout their lifespan.

Solutions If Solar Panels Are Not Working

If your solar panels stop working, you can take several steps to fix the problem. Many issues come from faulty inverters or charge controllers. Here are some solutions:

  1. Inspect and reset your circuit breaker: Sometimes, a tripped circuit breaker is why solar panels aren’t working. Check your home’s circuit breaker and reset it if necessary.
  2. Examine the inverter for issues: Both string inverters and micro-inverters can fail. If you see a red light on your inverter or no light at all, it might need repair or replacement.
  3. Clean any obstructions from solar panels: Dirt, leaves, and snow can block sunlight. Gently clean your panels with water and a soft brush to remove these obstructions.
  4. Ensure proper connection to the grid: Issues with grid connection may stop your system from working correctly. Call a professional solar company to check if everything is connected right.
  5. Check for shading problems: Sometimes new buildings or growing trees cast shadows on your panels during different times of the day or year. Trim branches or consult with a solar expert on possible solutions.
  6. Monitor performance regularly: Use monitoring software to keep track of how much energy your solar photovoltaic (PV) system produces. Sudden drops in energy production might indicate a problem.
  7. Look into battery storage performance: If you have a solar battery, ensure it stores and releases energy as expected. Batteries sometimes degrade over time and may need replacement.
  8. Contact a professional solar PV technician: If you cannot find the solution yourself, hiring a professional from a reputable solar company can help diagnose and fix the problem.
  9. Consider updating old equipment: Solar technology advances quickly. Older systems might benefit from updated components like modern micro-inverters, power optimizers, or high-efficiency PV modules.
  10. Install additional panels if needed: Sometimes, initial installations do not generate enough power for your needs—add more panels if space allows and it makes sense for your energy consumption needs.


Knowing if your solar panels are working is straightforward. Check the green light on your inverter for good performance. Your electricity bills should show lower usage, indicating effective solar power generation.

Keep panels free from obstructions like dirt and debris for optimal function. Regular checks ensure you catch any issues early, ensuring your solar energy system works efficiently to power your home with clean energy.
