You already know your home’s solar panels keep energy costs low, and you know they reduce your home’s carbon footprint. But if an issue arises, you may not know if your solar panels are damaged or experiencing other operational issues. Below are a few indicators homeowners should be watching for to know when it’s time to get their solar panels repaired.

How to Tell If Your Solar Panel Needs to Be Replaced

1. Cracks in Glass Casing

Defects in the glass casing of your panels, which can be caused by things like hail storms and flying debris, should be easy to spot from the ground. Look for cracks, scratches, or shattering, all of which can impact the panel’s effectiveness. Unfortunately, damage to the glass casing often leads to moisture getting inside the panel, which can lead to further complications. 

2. Diminished Power Production

The power produced by solar panels is measured in kilowatts per day. If you suspect a drop in the energy your panels are producing, compare your meter’s readings to the manufacturer’s average. While some variation can be attributed to poor weather conditions, mechanical failure could be another cause, especially if the decrease in output continues.

3. Error Messages on the Inverter

The inverter is a device that takes the direct current generated by the panel and converts it into the alternating current you use in your home. If there’s something amiss, the inverter should display an error message that corresponds to a specific issue. Although, in some cases, the problem could be the inverter itself. Error messages will also alert you to other causes for concern, like moisture in the cabling and short-circuits, which sometimes results in an isolation alarm.
