BIPVco solar panels use industry leading super thin photovoltaic cells manufactured by Miasole. BIPVco builds the module by layering the bespoke top sheet, diodes, bus bar, the insulating layers and the cells. The functional solar module and the integrated junction box are then fused directly onto a pre-coated metal roof or membrane substrate, forming a photovoltaic panel, by BIPVCo’s unique in-house developed process. These components combine to create a photovoltaic roof system that can be installed in the same way as a conventional roofing system.
BIPVco uses CIGS technology (Copper Indium Gallium Selenide), thin-film solar cells to convert sunlight to energy. They differ from traditional crystalline based Building Applied Photovoltaic systems (BAPV), which use heavier bulkier solar photovoltaic panels, mounted on top of roofs or other spaces after the construction of the building. A few of the advantages of CIGS compared to traditional crystalline technology:
Less bulky, more flexible and light weight
Better shade tolerance
Performs better in low light conditions
Requires fewer materials and less energy to manufacture
Requires very little maintenance.
High efficiency thin film CIGS PV cells/Modules
Install high generating per capacity unit area of available roof
See More benefits
Generally able to take the form of building envelope and not break / crack.
Multiple diodes & cell interconnections
Avoids disproportionate loss of output when shaded. Built in redundancy for cell connections improves factor or safety by design in the event of cell disconnect.
No degradation at high voltage
Reduced risk of degradation over the years.
Avoids adverse wind effects & need for ballasting on flat membrane roofs.
