We are setting up a solar module assembly facility with an estimated annual production capacity of 500a?ˉkW/year. We are interested in acquiring a solar cell stringer machine for this scale of production. Please provide technical specifications, minimum installation requirements, applicable certifications, supported cell types, output capacity, options for semi - automatic vs. fully automatic models, quotation including lead time, warranty and after - sales support. Advise which model is best for a small - to - medium scale module assembler and if there are cost - effective options for our facility size.
