Pack Contents
The audited product is a 25-cell pack. Tabbing wire, bus wire, flux, encapsulation materials, glass, backsheet, junction hardware, and a finished panel enclosure are not listed as included. Select those materials separately to suit the planned module construction and process.
Project Planning
Determine the required series and parallel arrangement before soldering, allowing space for cell gaps, bus connections, and edge clearance. Bare cells should be handled and supported carefully throughout assembly. Validate polarity, individual-cell output, string continuity, and the completed laminate with suitable test equipment. Finished voltage and power depend on the electrical layout, cell matching, irradiance, temperature, and workmanship; this listing does not represent a complete 12V module.
