Early PV modules mostly used silicone as encapsulant, which resulted in very durable and reliable modules. However, silicone encapsulation was replaced at the end of the eighties by EVA for process and cost reasons. Thanks to the simultaneous emergence of a market for very robust and durable modules (long lifetime utility modules, sunbelt region modules, tropical region modules) and the development of specific silicones and encapsulation processes meeting the requirements of modern PV manufacturing, silicone encapsulated panels have become again a feasible and attractive technology option. Double glass modules with silicone encapsulation have recently been launched and are now mass produced and globally commercialized. The combination of the glass-glass structure and silicone is shown to lead to exceptional durability in accelerated aging tests.
