Did you know that simple maintenance checks can drastically improve your solar system's performance?

With no moving parts, solar energy systems are low-maintenance, long-lasting investments. However, just like any other piece of equipment that is exposed to the weather, issues can occasionally pop up.

The most obvious sign equipment isn’t functioning properly is an unexpected or sudden increase in your electric bill. If you find yourself in this scenario, here are four issues that could be the cause.

 

Note: All systems installed by Paradise Energy are backed by our Triple Ten Guarantee. That means we will monitor your solar system and fix any issues within the first ten years of installation. Many manufacturers also stand behind their products by offering warranties of 5-25+ years. 

 

1. Physical Damage

There could be a damaged panel. Solar panels are made with a protective glass cover, much like a car windshield. They are proven to withstand hail or even bike tricks (not recommended).

 

However, a stone or some other particle can occasionally hit the panel just right and cause damage.

 

2. How Can Dirt Affect Your Solar Panel Efficiency?

Being exposed to the environment can allow for dirt, pollen, etc., to affect solar panels' efficiency. In most cases, the rain will rinse away these items, but a cleaning could sometimes be needed. 

 

DO NOT use a power washer to wash your panels. Doing so can damage the panels' seals and allow moisture to work its way into the inner parts. If the panels are located in an area you can safely reach, using a garden hose, a long-handled brush, and a bucket of soapy water to clean the modules is okay. Avoid walking on the modules.

 

We strongly discourage climbing or working on your roof without approved safety equipment.

3. What Are Arc Faults and How Can They Affect Your System?

Loose electrical connections within the system can cause arc faults. Inverters are now built with arc fault protection, which will cause them to shut down as soon as they sense anything they interpret as an arc fault.

 

Typically, your inverter will display an error to indicate that it is in fault mode.

 

Regular checks by qualified technicians can help identify and fix potential risks before they escalate, keeping your solar system safe and functional. Stay proactive in maintaining your system to safeguard against the silent threat of arc faults and ensure optimal energy production.

 

4. Why is GFCI Important for Your Solar System’s Safety?

If the electrical current finds a path to the ground, it will trigger a ground fault alert. Inverters are designed to shut down when such an incident occurs.

Some inverters have an internal fuse that blows whenever a ground fault occurs; others reset themselves and begin to produce again after the cause of the fault is cleared.

 

Faults can be caused by:

  • Moisture inside a junction box or other type of electrical enclosure
  • Broken panels
  • Squirrels or other rodents causing damage to wiring
