Table 2 Max Frame Spacing and Footing Options of Panel Dimensions 2m x 1.1m
Notes.
- For 25 degrees tilt angle the spacing and footing options for 30 degrees can be adopted (Cp=474-
585mm, post hight = 1200-1085mm AG, max post depth1.715m).
- For concrete piers foundation we recommend to use 25 MPa strength concrete. Other pier sizes
possible,contact Gamcorp.The minimum post embedment depth in the pier shall be approximately
0.9 of the pier depth.
- T-Rails overhang: 0.4*S maximum.

- (*): when using Clenergy East-West adaptor (if different to the
spacing without adaptor);
- T-Rails overhang: 0.4*S maximum.
