Loosely hanging cables with low bending radius were found. Modules with manufacturing issues found on site. It is recommended to (i) optimize the cable layout, (ii) relocate the tables, (iii) replace damaged modules and re-sort lower performing modules, (iv) retrofit the mounting structure, (v) add module to module equipotential bonding, and (vi) install a weather station or at least an irradiation sensor on the module plane. The estimated production boost expected by the retrofitting actions lies between 6.6% and 11.9%.
Poor cable management: Loosely hanging cables. Missing string labelling at the module end. Water presence observed in cable connectors.
Some cable conduits are broken.
Manufacturing issues of busbar misalignment, delamination, and soldering paste on cell observed on modules.
Improper access to the site.
Angle beam disconnected from structure
rafter and post.
Module misalignment observed due to improper fixation of L brackets.
Modules installed in the west side are very close to the parapet wall, making accessibility challenging.
