A conventional PV module consists of 60 or 72 solar cells. In a traditional panel, that most of the panels on the market are, electricity passes through electrical wires fixed with lead-containing solders to the surface of the cell. In a back contact module, the solar electricity is derived from the back side of the cells to a module sized conductive and flexible circuit board. The front of the module is completely left for the power generation without any shading metal wires or poisonous lead.
The high degree of automation in the back contact technology produces efficient, consistent and durable solar modules. The back contact modules are environmentally friendly, non-toxic and at the end of service life recyclable.
Odd-Form modules refer to all module types other than a conventional 60/72 cell panel. Odd Form panels adapt to the environment or application. They are customized solutions for a special user, not bulk products.
Odd-Form can mean a different size, shape, structure or materials of a panel. The Odd-Form can be, for example, glass-glass, glass-composite or composite polymer. The choice of materials, the weight and impact resistance of the panel or clean looks might be decisive.
Odd Form may require the cells to be split very small if the panel needs to bend or flex. Different uses may set criteria that requires a lot of product development. before introduction.
