Abstract

The invention relates to a low-stress solar assembly and a manufacture method thereof. The low-stress solar assembly comprises a glass plate and a back membrane, wherein a plurality of battery sheets are arranged between the glass plate and the back membrane, and the battery sheets are connected into a whole through solder strips to form a battery sheet assembly; the battery sheet assembly is respectively fixed with the glass plate and the back membrane through assembly glue; and the centers of the solder strips are provided with bends which are arranged between every two adjacent battery sheets. The solder strips are pre-tensioned to ensure that the percentage elongations of the solder strips are consistent; the centers of the solder strips are provided with the bends, which can provide buffer when the solder strips are expanded with heat and contracted with cold so as to reduce the mutual stress function among the battery sheets; the battery sheets are preheated before welded with the solder strips, which reduces the temperature difference of the battery sheets and an iron head, reduces the heat stress function of the single battery sheet, greatly reduces the thermal stress of a solar assembly, improves the consistency and the yield of products, lowers the percentage of damage of the products, prolongs the service life of the solar assembly, decreases the use cost, and has safety and reliability.

Description

technical field [0001] The invention relates to a solar component and a manufacturing method thereof, in particular to a low-stress solar energy and a manufacturing method thereof, belonging to the technical field of solar energy. Background technique [0002] As a renewable new energy source, solar energy has been widely valued due to its energy-saving and environmental protection effects. Especially when electricity, coal, oil and other non-renewable energy resources are frequently running out, and energy issues have increasingly become a bottleneck restricting the development of the international society and economy, more and more countries have begun to implement the "Sunshine Plan" to develop solar energy resources and seek new economic development. power. At present, the commonly used solar modules have poor consistency, and the thermal stress of the solar modules is large, resulting in a high fragmentation rate of the solar modules, short service life, and high cost ...
