What critical property dictates the choice of the aluminum frame used for structural support of solar panels?

Answer

It is lightweight and highly resistant to corrosion.

The aluminum frame serves the purpose of providing rigid exterior support, maintaining the laminate structure's shape, and facilitating mounting. The material selection heavily favors aluminum due to its inherent physical characteristics crucial for outdoor use. Being lightweight simplifies the installation process significantly. More importantly for longevity, aluminum demonstrates high resistance to corrosion, a necessity since the panels are continuously exposed to various weather elements. This resistance ensures that the structural support itself does not become a point of premature failure, which is especially important when considering environmental threats like salty sea air near coastlines.
