Notes:
1. Terrain Category 2 (TC2) refers to open terrain, including grassland, with well-
scattered obstructions having heights generally from 1.5m to 5m, with no more than
two obstructions per hectare. This certificate will only cover Postmount PM3-A/2100
installed on TC2.
2. Panel weight calculated: 28kg
3. Solar Panels structural check by others.
4. Other piers dimensions are possible, contact Clenergy, if required.
5. For concrete pier foundations, use 25Mpa strength concrete (minimum).
6. The scope of this certification is for projects located at a maximum altitude of 100m
above sea level. No snow loads have been assessed.
7. If depth of footing is less than length of post below ground (embedment depth of post)
the post must be cut to suit the new level.
