Inside PV Manufacturing: SoliTek’s new fully automated module line in Lithuania

<p class="p1"><span class="s1">In the latest article of a new series on solar manufacturing facilities around the world, <b>pv magazine</b> presents SoliTek’s solar manufacturing facility in Vilnius, Lithuania. The company recently commissioned an upgraded 200 MW production line, as it transitions from semi-automated to fully-automated processes for critical assembly stages.</span></p><p>Lithuania-headquartered solar company SoliTek was founded in 2009. It launched the SoliTek brand in 2014, at which point it began to produce its first glass-glass solar modules. Today, the company manufactures solar modules at its Vilnius factory using 100% renewable energy, offering customers European-made solar solutions. According to figures on its website, 80% of its panels are exported to European markets including Germany, Italy, the Netherlands, Sweden and Switzerland.</p>
<p><span style="font-weight: 400;">SoliTek began commissioning an upgraded solar manufacturing line during the past winter, funded through its own investment. In an exclusive update to </span><b>pv magazine</b><span style="font-weight: 400;">, it announced the 200 MW production line is now fully operational and producing at full scale.</span></p>
<p><span style="font-weight: 400;">A spokesperson for the company explained that</span> <span style="font-weight: 400;">the primary driver behind the upgrade was the transition from semi-automated to fully-automated processes in critical assembly stages. </span></p>
<p><img alt="" class="size-medium wp-image-341235 aligncenter" height="360" src="https://www.pv-magazine.com/wp-content/uploads/2026/05/MLR07583-600x360.jpg" tabindex="0" width="600" /></p>
<p><span style="font-weight: 400;">“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 spokesperson said. “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.”</span></p>
<p><span style="font-weight: 400;">As part of the upgrade, SoliTek has transitioned from using outsourced pre-cut cells to an integrated, high-precision in-house laser cutting unit. The company says the change allows for total quality control over the cutting process and minimizes the risk of microcracks that can occur during the transport of pre-cut cells from external suppliers.</span></p>
<p><span style="font-weight: 400;">SoliTek’s new production line is also 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,” the company explained.</span></p>
<p><span style="font-weight: 400;">Beyond technological improvements, SoliTek says 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,” the company also told</span><b> pv magazine</b><span style="font-weight: 400;">.</span></p>

<p><span style="font-weight: 400;">Following the upgrade of its production line, SoliTek has introduced a new module series designed to meet applications ranging from agrivoltaics to rooftop installations.</span></p>
<p><span style="font-weight: 400;">The new portfolio features four distinct production lines. It includes SoliTek’s 300 W Agro solar modules, with efficiencies between 14.87% to 15.01%, that are designed for agrivoltaics and capable of withstanding hail of up to 50 mm. Meanwhile, </span><span style="font-weight: 400;">SoliTek’s 445 W solar module series, with efficiencies of 22.56% to 22.77%, and anti-glare 445 W Satin solar modules, with efficiencies of 22.06% to 22.27%,</span><span style="font-weight: 400;"> are designed primarily for residential markets.</span></p>
<p><span style="font-weight: 400;">Each of these product lines are available in frameless, framed and Solrif configurations, the latter of which integrates the solar panel directly into a rooftop structure via a collaboration with Swiss mounting solutions company Schweizer.</span></p>
<p><img alt="" class="size-medium wp-image-341238 aligncenter" height="400" src="https://www.pv-magazine.com/wp-content/uploads/2026/05/IMG_4820-600x400.jpg" tabindex="0" width="600" /></p>
<p><span style="font-weight: 400;">SoliTek's new series is rounded out by the 510 W Magnus solar module, an up to 22.93%-efficient, transparent, framed glass/glass module capable of withstanding hail of up to 40 mm, which is designed for C&amp;I applications.</span></p>
<p><span style="font-weight: 400;">A spokesperson explained that the Made in Europe-modules are currently being manufactured and available to SoliTek's partners across all markets. “As part of this portfolio, SoliTek has also introduced heat-strengthened glass technology,” they told <strong>pv magazine</strong>. “This material provides lower internal stress levels and is highly valued in several European markets, including Germany, for reducing the risk of falling particles.” </span><span style="font-weight: 400;">All of SoliTek’s product range also comes with a 30-year warranty, as listed on its website.</span></p>
