performance. Only carefully selected, high-quality materials are used: all quick-mounting rails are made of aluminium EN-AW 6063 T66, and all
roof attachments are made of stainless steel 1.4301 (AISI 304).
The load carrying capacity of all understructure elements is calculated in accordance with the European EC Eurocode standard under the following
conditions:
• Height above sea level: 400 m (1,312')
• Snow load zone: A2
• Wind load zone: 2
• Building height: max. 12 m (9' 4")
• Roof pitch: 30°
• Solar panel weight: 18.5 kg (40 lbs)
• Standard BISOL module size: 1,649 × 991 × 40 mm (64.92" x 39.02" x 1.575")
In addition to the above-mentioned standard conditions, all BISOL rails can be used in any snow or wind load zone. Depending on the snow and
wind load zones, the maximum span of profiles may differ.

12. BISOL PLASTIC BASE
Product code: SE-KST-B0030
The innovative plastic base was developed specifically for use with BISOL photovoltaic modules. The base allows for the construction
of an aerodynamic structure without having to penetrate the roof, and is particularly suitable for flat roofs. Its design reflects an
expert understanding of the laws of thermodynamics, providing more efficient cooling of the photovoltaic modules.
Made of UV-resistant polyethylene of high density, these bases exhibit good mechanical properties at high and low temperatures.
BISOL plastic base weighs much less than the typical aluminium parts and is extremely easy to install. Thus, the weight and costs of
the base can be reduced by up to 20%, while the time it takes to set it up can be reduced by more than 80%. The base is stackable
for easy transport - 40 pieces can fit onto a standard palette. The inclination of the PV-module with regard to the roof is 12,5° which
enables the optimum ratio between the energy yield and the number of PV-modules on the roof.
Bases ready for transport

13. INSTALLING BISOL PLASTIC BASES
BISOL plastic bases can be linked together laterally and longitudinally by using 50/50/5 mm (2.0"/2.0"/0.2") aluminium brackets, giving the power
plant greater homogeneity on the roof so as to provide for better resistance against the atmospheric influences. In the case of larger wind loads
on exposed zones (e.g. roof edges), the plastic base can be loaded with extra ballast to ensure the stability of the structure in unfavourable wind
conditions (wind gusts).

14. ALUMINIUM TRIANGULAR UNDERSTRUCTURE
Product code: Project specific
The aluminium triangular understructure is constructed from L-shape sections, and is suitable for flat roofs. Such understructures
are extremely flexible, as they allow for inclination adjustment of the understructure and the number of modules in height, while
the bolts connections reduce the necessary installation time and save the costs of welding. The triangular understructure can easily
be integrated with other BISOL elements.
In addition to the custom-made triangular understructures, prefabricated BISOL triangular understructures are also available.
The prefabricated triangular understructure with riveted joints further reduces the costs and time of installation. For protection
against strong winds, the aluminium triangular understructure can be equipped with the specially designed windshield, allowing the
installation of structures on locations with higher wind loads.
