Abstract
The placement of solar cell modules in various climates and locations throughou t the world esults in different degrees and combinations of enviromental stresses. Coupled with a design life time goal of 20 years, early detection and correction of module design deficiencies can result in ( 23) significantly better long-term economics. The present work concentrates on developing three types
~f modules design using different materials such as glass and plastics for encapsulation to meet the requirements. Except for the cells, sylgard 184, all materials used in the
modules were obtained from the local market. The su pe restrate modules were fabricated by assembling 2 x 2 solar
cells with glass sylgard 184aluminium foil type A), glass sylgard 184 Foot wear (F.W.) (type B) and glass oly-
urethane aluminium foil (type C).
Using lamination and potting techniquesThe life tests conducted in our work have to be able to predict module reliability when the module is operating in a specified environment.
Various electrical performance and
environmental testing requirements are discussed in terms of their significance as well as the rational for the specified levels and durations.
Concurrent with the laboratory environmentl testing .
