ABSTRACT

Because the primary function of a photovoltaic system is to convert sunlight to electricity, often the role and importance of the mechanical aspects of the system are ignored. Most photovoltaic modules are designed to last 20 years or longer. It is important that the other components in the system, including mechanical components, have lifetimes equivalent to those for the PV modules. It is also important that the mechanical design requirements of the system be consistent with the performance requirements as well as with the operational requirements of the system.
