The factors influencing the bending strength of bifacial photovoltaic modules glass were systematically analyzed. The four-point bending test was employed to measure the bending strength of the glass. The results demonstrated that adjusting specific ingredient ratios, increasing product thickness, enlarging product size, improving edge quality, and reducing microcracks could enhance bending strength. However, the effects of stress distribution and processing techniques on bending strength were complex and should be set reasonably based on actual application situations. Additionally, attention should also be paid to side effects while improving bending strength. Currently, measurements deviations in the industry were approximately 5%, thus, establishing a comprehensive maintenance and management system for measurement systems was crucial. The study summarized and concluded a rating table for factors affecting bending strength, assigning scores to each factor according to a certain weight. The findings provided theoretical and practical guidance for standardizing and sustainably improving bending strength in photovoltaic glass applications.
