FAQS about Degrading PV panels
What is solar panel degradation?
Solar panel degradation comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. Aging is the main factor affecting solar panel degradation, this can cause corrosion, and delamination, also affecting the properties of PV materials.
How often does solar panel degradation occur?
