oThe site
oThe surroundings and the topography of the site
oDimensions, surface and ground composition
oPosition and size of obstacles (terrain levels, existing or planned pipeline routes, traffic routes and
other structures, etc.)
oDrainage features
oSite preparation, i.e. grading, if necessary
If in doubt, measure the friction between the system components and the ground surface to validate the
assumptions made in the design documents. If the project details in the planning documents do not match
the values on-site, contact the responsible planner. This is especially true if the planning is not based on
detailed and up-to-date data collection on-site.
Ensure that the weight and dimensions of the ballast blocks are in accordance with the planning doc-
uments. The ballast plans from AEROTOOL are optimized for specific block characteristics. If the block spe-
cified in the design report is not used, then a revised ballast plan will be needed.
The selection and procurement of the ballast blocks must be handled by the customer. Ensure that the bal-
last blocks have sufficient density to remain stable under local conditions over the lifetime of the PV system.
Before using ground screws, ensure that their entire length can be permanently anchored in the ground.
Caution against the following should be taken:
oHazards from contaminated sites
oIncreased risk of corrosion due to high groundwater level and/or aggressive soil chemistry (strongly
acidic or alkaline reaction).
oRestrictions on anchorage depth, e.g. in the soil depth above the cap of a landfill, excessive content
of stones and boulders (which may require pre-drilling).
If the anchorage depth is limited, a shorter ground screw with a length of 10 inches (280 mm) can be used
instead of the standard 18 inch (460 mm) ground screw. If a shorter ground screw (lower load capacity)
must be used in place of the standard ground screw, then a new statics plan is required.
Aerocompact accepts no liability for damage and malfunctions caused by:
oimproper use
ouse of non-certified components.
ounauthorized modifications to the product.
oimproper handling of the product.
oInstallation errors
oFailure to comply with the installation instructions or planning documents.
Guarantee
The warranty period for the system is 25 years. The warranty period for galvanized steel parts is 10 years. The
guarantee is only valid if the installation is carried out professionally and all system components are pur-
chased from Aerocompact. If the assembly instructions or the planning documents are disregarded, the war-
ranty will be invalidated.
