Sonobond Ultrasonic Metal Welding for Solar Panels
Ultrasonic photovoltaic modular welding system.
West Chester, PA — Sonobond?s MS-5010PV Ultrasonic Photovoltaic (PV) Modular system is designed for easy integration into the production lines of solar panel manufacturers. The unit consists of an ultrasonic head with a rotatable welding disk and a power supply. The head has a keyed shaft which can be used to rotate the welding disk at the same speed as the advancing photovoltaic panel. In addition, the system's power supply features a solid-state frequency converter and automatic tuning control. This eliminates the need to manually adjust the frequency. Sonobond modules are typically placed at each side of the traversing panel. Manufacturers can choose either the standard 110V system or a 220V system. Power consumption is only 100 watts.

According to the company, the MS-5010PV Ultrasonic Photovoltaic (PV) Modular System is playing a vital role in the growth of the solar panel industry. The Ultrasonic PV Modular System is fast, efficient, and cost-effective. It is suitable for welding aluminum strips onto the photovoltaic cells that constitute solar panels — creating arrays with excellent conductivity.

The ultrasonic system is especially suitable for welding aluminum foil to the metallized glass on the photovoltaic cells that comprise solar panels. The equipment creates an ultra-reliable, solid-state metallurgical bond. The resulting interconnects between the PV cells result in an array with excellent conductivity.

The system produces seam welds by applying mechanical vibratory energy under pressure. The process takes just seconds, while using no fluxes, tapes, solder, or other consumables. Solar panel manufacturers find that this ultrasonic bonding process offers substantial advantages in the production of the solar cells used to make up solar panels. In addition to its speed, the process is environmentally-friendly, economical, and does not produce excessive heat.
