Large wind turbine blades are primarily constructed from composite materials, most commonly fiberglass (glass fiber reinforced polymer). Carbon fiber is increasingly used, especially in the outer sections of very long blades, for its high strength-to-weight ratio and stiffness.

Most blades use glass fiber reinforced polymer (GFRP), a cost-effective material with a good strength-to-weight ratio, while longer blades often use carbon fiber reinforced polymer (CFRP) in the main spar for added stiffness and weight reduction.

Solar panels are made primarily from silicon-based solar cells, protected by tempered glass, supported by aluminum frames, and interconnected with copper and silver conductors, while encapsulation layers and polymer backsheets provide insulation, durability, and weather.
