If you use solar panels to generate electricity from the sun light you normally can rely on the quality of the products. But check your supplier and the warranty conditions very carefully. It is essential to your economic success.
And check the system professionally. Every solar generator needs a monitoring system to provide operational data. If the module strings weaken, there must be a product damage or broken connection.
Sometimes it starts with tiny little spots which get very hot. The heat make them grow. That is why they are called hot spots. May be, they appear on the front side of the cells, may be in the connection box or in the foil on the rear. If you don‘t monitor and maintain your solar system your panels might end like the ones in the lab – as shown above. (HS)
