What is BS EN 62788-1-2-Photovoltaic encapsulants and polymeric materials about?
The EN 62788 series is a European standard that discusses materials used in photovoltaic modules. The main objective of EN 62788 is to provide the measurement procedures for materials used in photovoltaic modules.
BS EN 62788-1-2 is a part of a series of documents that provides a method and guidelines for measuring the volume resistivity of materials used as encapsulation, edge seals, front sheets, back sheets, or any other insulating material in a photovoltaic (PV) module. The test is performed on dry, humid, or wet preconditioned samples. In the case of front sheets and back sheets comprised of multiple layers, the measured resistivity is an effective value. This test is designed for room temperature measurement but can also be utilized at higher temperatures.
Degradation of PV modules is known to occur in part by electrochemical corrosion, and other potential induced degradation processes. These processes may be dependent upon the resistivity of a polymeric component. Therefore, the DC resistivity of polymeric components is relevant to module design and durability in the field. The resistivity may depend on cure state, temperature, water content, and voltage history. A number of options are included to allow the measurement to be performed in a manner consistent with representative fielded module conditions.
