Resource: Carbon Impact Studies: Photovoltaic panels
This 2008 report compares the carbon footprint of a remanufactured PV panel to that of a new one.
Tuesday, 21st July 2009
The analysis presented here already appears within the Product Group Report from CRR on the potential of remanufacturing photovoltaic panels (available on this site). This report summarises the method and outputs of a short-cut 'carbon footprint' of a remanufactured panel over a new panel tool. The inventory of component impacts included materials, energy, transport logistics, remanufacturing ratio for each part, and disposal and waste scenarios.
In summary, wafer and cell productions are the major burdens for both environmental and energy point of view. They also contribute to about 60% of the manufacturing costs. Therefore there is every reason to implement remanufacture/reuse of these components as a better option than recycling. PV OEMs should consider disassembly for these parts to achieve the savings highlighted in this report.
