AI Technical Summary
High-temperature soldering during the welding of electrodes in existing photovoltaic modules may burn the photovoltaic panels, affecting their performance and causing oxidation and aging of the tin-plated copper strip, reducing conductivity and affecting service life.
By using spot welding for positioning and then filling with conductive silver paste, the high-temperature welding time is reduced. By filling the electrode welding groove of the photovoltaic panel with cured conductive silver paste, conductivity is ensured and damage to the photovoltaic panel and tin-plated copper strip is reduced.
This effectively reduces the damage to photovoltaic panels and tin-plated copper strips caused by high-temperature welding, and improves the service life and conductivity of photovoltaic panels.
