Super-sized solar photovoltaic panels

Titanium leads the way in Japan's most recent leap into renewable energy. The country has now unveiled the first solar panel that makes use of titanium – a technology that could potentially be 1000 times more powerful than traditional cells.

While early leaders such as Trina Solar, Jinko Solar, Canadian Solar, Risen Energy, and JA Solar laid the groundwork for high-power panels in the 600–700W range, a new wave of manufacturers is now surpassing those limits.

Besides the standard sizes, a few premium manufacturers, such as SunPower and Panasonic, produce unique 96 and 104-cell panels. The industry-standard panel size for much of the last decade was built around the 156mm x 156mm or 6-inch square cell format.

As of early 2025, this panel represents TW Solar's highest-wattage commercial module, although mass production above 760W is not expected until 2026. Despite these record-breaking developments, large-scale production of modules rated above 720W is still in early phases.

Despite the publicity surrounding the many high-powered panels, the PV cell advancements that enable these higher power ratings are universal. Thanks to these innovations, regular-size commercial and residential solar panels have also seen a significant increase in power, with 440W to 550W panels now standard.

Such panels require more, and larger cells, meaning larger, heavier modules, higher currents and lower voltage values. That has resulted in the most pluralized range of cell-to-module options ever seen. Like any new PV technology, large-format modules come with hotly debated benefits and downsides.
