SoliTek Modernized European Facility Reaches Full Operational Capacity

After successfully commissioning its upgraded manufacturing line this past winter, SoliTek announces that the facility is now fully operational and producing at full scale. This modernization marks a significant step for European PV manufacturing, reflecting the company’s strategic objective to increase efficiency and support next-generation technology while maintaining a strictly local production footprint.

Maximum Precision Through Full Automation

The primary driver behind the upgrade was the transition from semi-automated to fully automated processes in critical assembly stages. By integrating a fully automated framing station and autobussing equipment, SoliTek has significantly reduced manual intervention, ensuring consistent cycle times and eliminating human-related variability.

The automated system utilizes high-accuracy machine vision and uniform thermal bonding, which enhances the long-term durability of the modules. This shift allows for tighter process control and repeatability across all production batches.

In-house Quality Control and Technical Upgrades

A key technical shift is the transition from using outsourced pre-cut cells to an integrated, high-precision in-house laser cutting unit. This allows SoliTek to maintain total quality control over the cutting process. By utilizing internal laser technology, the company minimizes the risk of microcracks that typically occur during the transport of pre-cut cells from external suppliers.

The line is now specifically optimized for the industry-standard G12R cell format. The rectangular format of these cells enables improved packing density within the module, increasing the total active area and resulting in higher power output compared to traditional square wafers.

Operational Efficiency and Sustainability

Beyond quality improvements, the full-scale operation of the new line optimizes the "cost per watt" by increasing the speed of the assembly cycle and decreasing manual labor requirements. The high precision of the new equipment also contributes to SoliTek's sustainability goals by lowering material waste through reduced breakage and optimized cutting processes.

Expanded Product Portfolio

With the line now operating at 100% capacity, SoliTek continues to deliver its recently launched, high-efficiency module portfolio. These Made in Europe modules feature power ratings of up to 455 W for residential panels and 510 W for C&I applications.

As part of this portfolio, SoliTek has also introduced heat-strengthened glass technology. This material provides lower internal stress levels and is highly valued in several European markets, including Germany, for reducing the risk of falling particles.

The upgraded portfolio is currently being manufactured and is available to SoliTek partners across all markets.
