Polycrystalline PV panel OKACELL

transparentcustominsulated

Product Details
OKACELL makes building-integrated photovoltaic available for architectural applications. OKACELL offers the greatest possible variety of designs with different cell types, cell colours and customized alignment. A wide range of module shapes is possible in addition to rectangular panels. OKACELL is available as monolithic glazing and insulated glazing for facade and roof.

• Building-integrated photovoltaic

Benefit

• Individual design options
• High efficiency up to 180 Wp/m² depending on the cell type and coverage density
• Extensive support in planning
• Combination with OKALUX light diffusing insulated glass
• Combination with individually printed front glasses
• Visibility for birds

Build-up + function
The cells are embedded in a laminated glass made from tempered/toughened glass or heat-strengthened glass (low-iron glass). PVB or EVA foil is used as the intermediate layer.

max glass dimensions | up to 2200 mm x 3600 mm
Minimum size | with two cells alongside each other approx. 400 mm
Individual cell size | 158.75 mm x 158.75 mm
Minimum cell spacing | ≥ 2.5 mm
Distance from cell to edge seal | ≥ 20 mm
Lateral projection connector | approx. 10 mm (cable diameter)

Electrical data
Efficiency | approx. 22.2 %
Power | 180 Wp/m² at 100 % coverage density

Due to the rapid technical progress in the development of new cell types and sizes, it may be that a specific type of cell is no longer available at a later date. The inherent colour and the brightness of crystalline cells is not a defined property. Therefore, colour differences may occur within a module and between different modules.

Technical data
Technical values of standard types
U-value | 1.0 to 1.4 W/(m2K) as insulation glazing and up to 0.8 W/(m2K) in combination with OKALUX K
TSET | ≥ 12 %
T_v | 10 % to 80 %

Legend and related sizes
U | W/(m2K) | DIN EN 673 | Heat transfer coefficient, Ug = U
| | DIN EN 674 |
TSET | % | DIN EN 410 | Total energy transmittance
T_v | % | DIN EN 410 | Light permeability (direct/hemispheric)

The specified values are approximate. They are based upon measurements by recognised test institutes and the derived calculations.
