This document establishes qualification and quality requirements for the electrical components integrated onto spacecraft solar panels that carry single crystal silicon solar cells or gallium arsenide solar cells having any number of junctions including those with metamorphic and inverted metamorphic structure. In this standard the term panel defines the assembly of electrical components to be tested. The standard also defines requirements for solar panel manufacturers' quality systems and for qualification and characterization of the electrical components on solar panels. This standard fully addresses the qualification of all panel components and the panel substrate only as they affect electrical performance. Requirements for acceptance testing are not defined in this document. In accordance with the conditions stated in this section@ this standard accepts qualification and characterization by similarity when approved in writing by the customer.
