Abstract
Abstract An enclosed solar cell array. The array is enclosed between a metal back plate and a cover glass. The edges of the enclosure are sealed by a pliable sealant material and a spring loaded bezel that is riveted or welded in place. The interior of the enclosure is filled with a potting material which surrounds and cushions the solar cell array. During the module fabrication a fixture supports the enclosure parts and provides a temporary edge seal to facilitate the potting procedure. Controlled flexure of the enclosure back plate and controlled spacing of the cover glass ensure a compressive loading of the potting material which eliminates possible delamination of the potting material in its subsequent usage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
An enclosed solar cell module which comprises: a cover glass; a flexible metallic back plate, configured so that a solar cell array can be positioned between said cover glass and said back plate, said back plate having an edge lip against which said cover glass can sit; an array of solar cells positioned between said cover glass and said back plate; a potting material filling the volume between said cover glass and said back plate and surrounding said solar cell array, said potting material flexing said back plate and being compressively loaded by positioning said cover glass against said edge lip; and an edge seal around said enclosure comprising a pliable gasket material and a metal bezel, said edge seal confining said potting material within said enclosure and holding said cover glass against said edge lip.
Claim 2
Dependent Claim
