If you’re not a solar expert, you’ll never even know if your panels are still working efficiently. However, here are some signs your solar panels aren’t working as they used to:

• Lower electrical output – write down your solar panels’ performance in the beginning when their performance is at peak levels. The next time you check, a significant drop in the output might indicate a problem.

• Visual inspection – did you notice visible damage on a panel? Is there some debris causing blockages? If so, remove it, and you might see improved performance.

• Age – it’s normal to expect some performance drop as the panels age.If you have solar systems installed a long time ago and need trustworthy solar panel installers to check or maintain them, give us a call on 02 9567 5886.
