The present invention relates to a method and a device for detecting defects in a photovoltaic panel by using an image of the photovoltaic panel. The photovoltaic panel defect detection method and device according to the present invention detect defects that cannot be detected in an EL image of the photovoltaic panel by using an artificial intelligence unit pre-trained with an optical image rather than the EL image, thereby classifying defects by type, and measure the size of defects so as to determine whether the panel is ultimately defective, and thus defect determination in a photovoltaic panel production process can be faster and more accurate such that process time is reduced and defect detection rate is increased, thereby enabling cost losses to be reduced.

Embodiments of a solar table mobile transport with collapsible manipulators are described. The collapsible manipulators may be scissor lifts, direct lifts, or pivot lifts, that couple to a torque tube of the solar table and provide at least vertical movement of the solar table. Once the mobile transport approaches an installation spot between installation piles, the mobile transport lifts the solar table by unfolding the collapsible manipulators such that that solar table may cross the pile line and the mobile transport can maneuver between the installation piles. The compactness of the mobile transport, especially when the collapsible manipulators are vertically installed, greatly enhances the maneuverability of the mobile transport within the limited space between the piles. Such a capability of mobile transport maneuverability in combination of solar table alignment facilitates an installation efficiency of the solar table.
