Process automation for photovoltaic module assembly and testing

Automated processes are being developed at Spire Corporation for photovoltaic (PV) module production. These processes address the module assembly and testing tasks done after lamination. Two automated systems have been designed, built and tested: a buffer system for dispensing and storing modules; and a system for testing module safety and performance. Two additional systems are now under development: an edge trimmer for removing excess encapsulant and back cover film from module edges after lamination, and an edge sealer and framer for dispensing edge sealant and installing frames on trimmed modules. The system designs and automated processes developed in this program are presented.
