How Can I Tell If My Solar Panels Are Working?

Unfortunately, solar panels can malfunction every now and then, which is why you should inspect your solar equipment for potential issues regularly. An underperforming solar system can lead to an increased electrical bill and more significant problems over time.

In this article, we give you useful tips to ensure your home solar system is working as it should be. We’ll also tell you what to do if you come across any faults.

How To Tell If Your Solar Panel System Is Working Properly

If your solar panels are working properly, they should be generating electricity daily. While the solar output may vary depending on the amount of direct sunlight available, your solar cells should still produce power, even in rainy and winter conditions.

• The indicator light on your inverter should be green during daylight hours. This is a clear sign that the solar panels work and that the system is operating as it should be. If energy production levels are very low or non-existent, then you have a problem.
• While your utility bills may fluctuate depending on how much power you’re using, they should remain relatively stable. Predictable electric bills are another attribute of a fully functioning solar system.
• In order for your solar panels to work efficiently, they need to be free from dust and debris. Therefore, clean solar panels will work better than dirty panels.

4 Tips To Monitor Your System’s Performance

It’s a good idea to keep an eye on how your system is performing so you can easily pick up on anything out of the ordinary. Here are a few tips:

1. Inspect your solar inverter

Your inverter plays an essential role in the overall functioning of your solar PV system. On a normal sunny day, there should always be a green light on the inverter. If you see a red or orange light, it could mean that your solar power system isn’t functioning properly.

2. Review your energy output

Your generation or solar meter should tell you exactly how much electricity your solar panels are producing. This number is typically given in kilowatts. You should have a general idea of a typical generation figure for your particular system so you know when things are ‘normal’ and when they aren’t.

3. Track your system’s data

There are plenty of online applications and solar monitoring systems that allow you to track your system’s data. At a glance, you’ll be able to determine how much energy your solar panels are producing. Some of these apps will even tell you which appliances are drawing power, so they can be very useful for checking system performance.

4. Test your battery from time to time

Most solar power systems include a solar battery to help store any excess energy generated by your solar panels. This can help power appliances at night and ensure a lower electric bill. To test your solar battery, connect a multimeter to your battery’s terminals. If the reading is much less than the battery’s listed voltage, then you may have an issue.

What Are Some of the Common Signs of Malfunction?

If you own a solar power system, it’s essential that you’re aware of the common indicators of potential malfunction. Some of the early warning signs include:

• An increased electricity bill
• Red or orange light on your inverter
• An error message on your generation meter or solar inverter
• Your solar power system keeps tripping

If you notice any of the above signs, you should take action immediately. Additionally, read our in-depth article on the most common solar panel problems.

What Should I Do If My Solar Panels Aren’t Working?

Before you call the experts, there are a few things you can do to potentially fix the problem on your own, including:

• Check the electrical panel to make sure a circuit breaker hasn’t tripped.
• Restart your inverter. This may get rid of the fault.
• Make sure your panels aren’t covered in sap from a nearby tree. Remove any debris from the panels.

While the above actions may help in certain situations, if the issue is due to faulty wiring or component damage, you will need to call an experienced solar installer to assess the situation.

FAQ

How often do my solar panels require maintenance services?

Your solar panels should get properly serviced at least once every two years. However, you should clean them every few months if you want to increase their efficiency. Make sure your roof is clear of debris and your solar panels are free from dust and grime.

How long should my solar panels last if I look after them correctly?

Typically, solar panels should last between 20 and 25 years if you look after them correctly. However, a number of factors can impact their lifespan, including where you live, how your panels were installed, the type of panels you purchased, and more.

Can I maintain and inspect my solar panels on my own?

In the UK, it is legal to install and maintain your own solar panels. However, it is best to leave the maintenance to a professional solar company if you want the job done properly. In between services, you can always inspect your panels from time to time. Just be very careful if you have to climb on the roof.
Final Thoughts

Solar power systems are known for being very reliable, but issues can arise from time to time.

Now you know a few ways to check if your solar panels are working correctly. Remember to physically inspect your panels occasionally and be aware of the warning signs. The sooner you catch a potential problem, the easier it will be to fix.
