Photovoltaic solar module assembly refers to the process of assembling photovoltaic solar cell modules using SMT materials and processes. This approach is gaining popularity to meet certain goals. PV cell stringing in solar module assembly is achieved using many common SMT materials and processes, such as solders, fluxes, and common reflow technologies. These techniques produce electrical interconnects in both a-Si and c-Si photovoltaic assembly technology.
To assemble a PV module, the process involves two basic steps: photovoltaic cell interconnect by stringing and PV module assembly by bussing. Connecting individual PV cells into a PV module is called solar cell tabbing or solar cell interconnect stringing. In this process, the cells are electrically connected using stringing ribbon.
A solar module typically contains 20–80 PV cells. This is referred to as cell bussing. Common SMT assembly materials — solder pastes, solder wire, solder preforms, and fluxes — are used to make interconnects during photovoltaic solar cell module assembly.
Photovoltaic (PV) solar cell module assembly is a preferred choice for EMS providers who are increasingly seeking to diversify and fill capacity.
