Solar panel issues are uncommon — and most system problems are not caused by the panel itself.
If your solar system is not producing as expected, the solar module is usually not the cause.
In many cases, system performance issues are related to other parts of the system or site conditions, including:
inverter issues
wiring or connector problems
damaged cables
installation-related issues
shading
dirt, debris, or bird droppings
animal damage
monitoring or communications faults
Solar module failure is very low, and when a module defect does occur, it usually becomes apparent early in the life of the system.

Start with a qualified solar service company
If your installer is no longer in business, the first step is to contact a qualified solar service company or licensed solar contractor to inspect the system. A trained technician should evaluate the full system before any conclusion is made about the solar panel.

What should be checked first
Before a module warranty claim is submitted, the servicing company should review common non-module causes, including:
inverter operation
system wiring and connectors
visible cable damage
module soiling or shading
animal or environmental damage
monitoring data and system performance history
installation and balance-of-system conditions
-
If the service company believes a module is the issue
If a qualified solar company determines that a SEG module may be defective, they should document their findings and perform the testing needed to support a warranty review. SEG will work with the servicing company to review the claim and process any valid module warranty claim in accordance with SEG’s limited warranty terms.
