If any obvious defects are found, the location shall be noted in the system logbook, so that they can be monitored in the future in case further deterioration affects the modules' output. 3. The condition of the array mounting frame will also be checked by supervisor cum tradesman. Items to observe shall include the array mounting bolts (e.g.bolt rusting) and ensure that the frame and modules are firmly secured. The junction boxes shall also be checked to ensure that the wires are not chewed by rodents or insects.

(vii) Wiring and connections Wiring installations shall be checked for any cracks, breaks or deterioration in the insulation/conduits. Inspect panel boxes to ensure that they have not become a home for rodents and insects. Also inspect connections for any corrosion and/or burning. Switches should not spark when turned on or off. The following sections of conduit and wiring should be checked for any signs of damage:- Solar panels to the DCDB, DCDB to the Inverter, Inverter to the ACDB, If any damage is found, the same shall be repaired/replaced . All ground wires shall be checked to ensure that they are not broken.
