 Inspection ParameterPanel Rear Side
    
    A Grade PanelsFrame Corners
    
    No tape gasket material to extend beyond the corner joints.Frame corners square with maximum 1 mm gap permitted.No sharp edges permitted at the corners.Front corners of panel to be flush with a level tolerance of +/-1 mm.No corner key material protruding into any gap between frame parts.Frame Corner Crimp
    
    4 crimp indentations for each inside frame part.Crimp indentations must not deform inside frame profile (for glass).Crimps to be centered about the corner joint.Frame Material
    
    No scratches, dents, bends, discoloration, or stains visible with the human eye from a distance
of 4.5 meters.Uniform surface condition and color.No sharp edges.Frame Gasket
    
    Total 4 cm gap in gasket tape allowed between frame and backskin.Junction Box Assembly
    
    Junction box is placed correctly according to assembly drawings (including tolernances).Junction box wall is not damaged or broken.Cables are not damaged.Female connector is attached to the left cable, male connector to the right cable (as viewed
from the rear).Sealant around the junction box perimeter must be applied in a uniform bead, 5-7 mm in
diameter, with no breaks.No lifting of the junction box away from the sealant.External Labels
    
    Correct labels attached according to assembly drawings.Backskin
    
    Smooth, clean surface with no holes, scratches, creases or cuts.Up to 5 small blisters or bubbles allowed, but each individual blister or bubble must be no
greater than 6mm in diameter.Solder ball impressions as long as the backskin is not breached (pierced).Panel Front SideGlass
    
    Clean surface, no physical scratches or damage, no finger print or suction cup marks. No frame
gasket visible.Non-penetrating surface blemishs visible with the human eye from a distance of 4.5 m allowed.Textured surface must face inward (opposite surface to outward facing anti-reflective surface).Encapsulant
    
    No bubbles permitted.Cell Layout

 Inspection ParameterPanel Rear Side
    
    A Grade PanelsCross-ties and cells must not touch; cells must not touch each other.No misaligned tabbing such that cells touch each other.No twisted tabbing between cells and cross-ties.Cell Appearance
    
    Gaps in the anti-reflective coating less than the hole gauge of 3.2 mm permitted.No more than 3 visible solder balls allowed per panel.Bare silicon must not visible across the total width of cell .Blue, purple, yellow color variations around edge of cells allowed (prior to lamination).Yellow areas within the cell allowed (prior to lamination).Distinct color variations within the cell allowed to a maximum diameter of 3.2 mm.No popping / hazing visible from arms length.No foreign material deposited on the front-side except for dots of metallization material less
than 1.50 mm in diameter. Total number of dots not to exceed 10 per cell.Cell Metallization
    
    Breaks in metallization finger pattern permitted up to 2 breaks of maximum 6.4 mm each and a
maximum of 6 such cells per panel.All metallization fingers and bus-bars must be present on the front surface.No breaks in bus-bars allowed.Finger and bus-bar metallization pattern can be skewed relative to the cell sides as long as
alignment of cells in a string is not affected.Metallization fingers must be straight, small waves allowed with a maximum disturbance length
of 3.0 mm.Wider than standard metallization fingers allowed if: a) less than twice the standard finger
width and b) visible disturbance pattern generated less than entire height or width of cell.Narrower than standard width fingers allowed.Cell Cracks and Edge Chips
    
    No cells visibly separated into two or more parts with cracks.Cell edges must not be broken more than 1.6 mm into the cell on the short-side and 1.3 mm on
the long-side.Cell edges must not be broken by more than 19.0 mm in length on the short-side and 12.7 mm on
the long-side.Multiple chips are accepted if the distance between the chips exceed 19.0 mm and above criteria
are not exceeded.Inter-Connect Wires
    
    Interconnect wire to be soldered to the bus-bar except for a length not to exceed 24 mm.Interconnect wire should cover at least 75% on the total bus-bar area.Both Sides of PanelAppearance
    
    No embedded foreign particles visible with the human eye from a distance of from 4.5 m.No embedded foreign metals allowed. Approved wire metal must be in designated locations as per
assembly drawings.
