HDPE Base 125 – NCD Schweiz AG

BISOL EasyMount HDPE Base 125

10-year durability guarantee

High wind stability

Low-ballast solution

No roof penetration

Quick and easy installation

Higher power-to-surface ratio

Lightweight mounting solution for flat roofs

BISOL EasyMount HDPE base 125 is made of high-density UV-resistant polyethylene. It requires no roof penetration and can be installed in high wind zones with minimum extra ballast, sparing the roof from unnecessary loads. The innovative mounting solution has been developed in-house and allows an unobtrusive on-roof installation at a 12.5° angle. Its design reflects an expert understanding of the laws of thermodynamics, providing more efficient cooling of the photovoltaic modules.

Wind loads calculated in accordance with Eurocode 1 (EN 1991-1-4). Information for additional wind zones available upon request.(X) The use of HDPE 125 bases is not recommended

HDPE bases 125 are horizontally connected, overlapped and attached to each other

Extra ballast can be placed into the HDPE base 125 (see ballast table).

Top and bottom fixings are attached to the BISOL PV module via connecting elements.

PV module is attached to the HDPE base 125 via slide-in top and bottom fixings.

Rows of HDPE bases 125 are vertically connected by L- profiles.
