Because they don’t have moving parts, solar systems are generally reliable and low-maintenance. But damaged or compromised solar panels can make it impossible for your system to produce power. Here are a few issues to look out for so you know when to seek a solar system repair expert's assistance.

3 Common Solar Panel Problems

1. Loose Wiring

Wiring connects the panels to each other, the solar inverter, their batteries, and your home’s main power panel. A single loose connection somewhere in the system can cause your power output to drop or fail entirely. Most solar contractors install system monitoring that allows you to track the performance of your array with a smartphone app, making it easy to pinpoint loose wires or faulty connections.

2. Dirty Panels

Over time, dirt, bird waste, and other debris can gather on the panels. Dirty panels don’t receive as much sunlight, which limits their energy production. Fortunately, you can easily clean the panels by hosing them off two or three times a year. Trimming back branches that might be blocking sunlight will also keep the panels operating at peak efficiency.

3. Overheating

You might think that high heat would make solar systems more efficient, but they perform best in cooler temperatures. Most solar panels lose efficiency in normal summer weather, so you might notice a drop-off in energy production during the hottest part of the day. This doesn’t necessarily indicate a problem with the panels themselves. If your area has long, warm summers, ask your solar installer about panels designed to perform in high heat.
