PV is a design element of a building and thus, should be considered in the very early stages of building concept design planning.

PV color

The PV color are originally grey, blue-black or black. Nowadays, the colors green, gold, brown and violet can be produces by anti-reflective coating. The various colors is desirable to architects to create novel appearance and architectural expression.

Shadow impacts Shadowing of the modules is an

important consideration, especially when they are connected together in a string. If a module lies in the shadow of an object, no more current is generated in this module. Instead, it uses the current from other modules. In general, shading should be avoided as much as possible.
