The solar panel that consists of copper plate and copper tube was successfully welded by ultrasonic seam welding. However it was not only expensive the copper material but also ultrasonic welding has many problem such as high error rate, difficulty of dissimilar material welding, noise, etc. At this study, the laser welding of solar panel with aluminum plate instead of copper. The welding were carried out with the pulsed Nd:YAG laser and the weld bead geometry was measured with the variation of pulse energy. Consequently, there was no difference between the ultrasonic and the laser welding on the performance of heat transfer capacities. Also the formation of intermetalic compound such as CuAl2 was increased with the pulse energy.
