How Do I Know if My Solar Panels Are Underperforming?

Decreased energy output, higher electricity bills, and visible damage like cracks are signs your solar panels might be underperforming. A maintenance service should include performance tests to confirm the system’s efficiency.


What Happens If My Inverter Displays a Fault Code?

If your inverter displays a fault code, it’s a signal that something is wrong with your system. The meaning of the code will vary by manufacturer. Consulting your system’s user manual or contacting a solar panel installer for an inspection is advisable.
