Abstract
The utility model relates to photovoltaic module technical field especially is related to a kind of anti-hidden crack battery string, including at least two battery pieces and the solder strip of application connection adjacent two battery pieces, solder strip includes upper straight section, upper bending section, middle section, lower bending section and lower straight section, upper straight section is used to connect with a battery piece top surface, upper straight section and battery piece top surface connection, upper bending section connects upper straight section and middle section, upper bending section and the clearance zone between the end of battery piece of its side, lower straight section is used to connect with the battery piece bottom surface of the battery piece of upper straight section connection, lower straight section and the bottom surface of battery piece connection, lower bending section connects middle section and lower bending section, upper bending section and the clearance zone between the end of battery piece of its side, solder strip keeps gap with battery piece edge by bending section design, avoid direct contact battery piece edge, effectively disperses external stress, reduces hidden crack risk.
