Abstract: In order to solve the problem of remote mountainous rural new energy， realize agricultural modernization， the solar panels traceability management system was established. The study designed prints bar codes in a silicon ingot side lasers， and proposed the traceability information management system which combined solar cells made from silicon ingot to link each step lamination with barcode. And for the image processing and recognition of the cell side of barcode cut into the thickness of micron grade， this study firstly used the digital image processing， then the method of scan pixels was applied to judge article black and white and code word segmentation， and the barcode image edge was smooth and could be identified， which could promote structure of agricultural facilities， and provide some technical supports for the development of modern agriculture， energy saving， environmental protection， etc.

Key words: silicon, micron thickness, barcode, image processing, traceability
