• Minimum plane of array irradiance

• Minimum plane of array irradiance conditions of 700W/m2, measured using the onsite meteorological stations installed as part of the Works. • Thermographic images shall be recorded in cases where the Modules display areas with a temperature differential of 15ºC or greater.• Thermographic images shall be focused and of the entire module area.Modules shall be replaced by the Contractor if any module display signs of any of the following issues:• Hot spot(s), with a temperature differential greater 20ºC, are present in the Module.• Inactive areas• Operating temperatures not compliant with the manufacturers stated range.• Major cracks.• Discolouration of cells.• Water ingress.• Cell micro-cracks/snail trails • EVA or backsheet delamination.• Backsheet punctures/rips.• Metal corrosion or cracking/ broken interconnects.• PID.• Glass breakage.• Snail trails• Glass yellowing• Junction box failure including adhesion/sealant failure.Frame sealant gaps.• Cell mismatch causing the operation of the bypass diodes or affecting the output characteristic of the module (as evidenced in a stepped or otherwise affected IV-curve etc.). and• Bypass diode defects and/or failure.The list presented above is not exhaustive. OTHER FUNCTIONAL TESTSIn addition to the abovementioned tests, the Contractor shall execute the following tests:• Earthing system:Ensure that all components are properly and firmly grounded in compliance with the Standards and Applicable regulations. Welding and bolt tightening shall be verified.The Earthing system shall be inspected and tested in accordance with the Standards.• Cables:All low-voltage DC and AC cables shall be tested for insulation resistance in accordance with IEC 60364-6, IEC 60364-7 and other applicable Standards.All low voltage cables shall be inspected and tested in accordance with IEC 60364-6, IEC 60364-7 and other applicable Standards.• Polarity tests:
