Cascadia 4x4's Contiguous Cell™ Technology (CCT) is used on all VSS System™ 2.0 solar modules. CCT is a new type of solar module assembly technique whereby solar cells are attached directly to each other using an electrically conductive adhesive along the entire length of the cell. This removes the weak connections that are common points of failure on traditional semi-flexible solar modules. It also allows solar cells to be placed without any space between them, reducing the unproductive surface area of the solar module.
