Abstract

An automated system provides automated manufacturing of photovoltaic standard power modules for utilization in a space solar array, in both rolled blanket and z-folded configurations. The automated system provides robotically controlled systems for CIC-ing, glassing, stringing, laydown and acceptance testing of interconnected photovoltaic devices. A method of manufacturing the photovoltaic standard power modules includes the steps of robotic positioning of diodes, interconnects and busbars onto a SPM stringing tray followed by the robotic positioning of bare cells into position adjacent to the diodes, interconnects and busbars to form strings. The SPM stringing tray is thereafter robotically positioned adjacent to an integral welder for welding of the front side of the string. Cover glass is thereafter robotically placed over the cells. The string is flipped and the backside of the string is robotically positioned for welding.

Claims (10)

1. A method of manufacturing standard power modules for solar arrays comprises the following steps:

positioning, via a robotically manipulated effector tool, a diode, an interconnecting electrical conductor and a busbar onto a stringing tray configured to receive a plurality of components for a standard power module in a preconfigured arrangement;

placing a bare cell into position adjacent to the diode, interconnecting electrical conductor, and the busbar to form a string, the string having a front side and a back side;

positioning, via a robotically manipulated effector tool, the front side of the string adjacent to a welder;

welding the front side of the string;

positioning, via a robotically manipulated effector tool, a cover glass over the string;

weighting the cover glass; and

turning the string over and welding the back side.

2. The method of claim 1 further comprising the step of applying a substrate to the back side of the string.

3. The method of claim 2 wherein the substrate comprises Kapton.
