In an expansive industrial rental yard under a clear, sunny sky with scattered clouds, small towable trailers are lined up neatly. Each trailer, designed for car towing, features solar panels that fold out into impressive arrays. The intricate folding mechanisms, hydraulic arms, and locking devices are clearly visible. Thick black cables, connected with cam lock PDUs, run from the solar panels to battery storage systems within the trailers. The setup appears freshly organized and ready for immediate use, with additional industrial machinery, temporary structures, and workers contributing to the dynamic and busy yard environment.
