About Energy consumption of photovoltaic panels from sand to finished products
This special report examines solar PV supply chains from raw materials all the way to the finished product, spanning the five main segments of the manufacturing process: polysilicon, ingots, wafers, cells and modules.
This special report examines solar PV supply chains from raw materials all the way to the finished product, spanning the five main segments of the manufacturing process: polysilicon, ingots, wafers, cells and modules.
The results highlight energy consumption, chemicals and transportation as the main hotspots of the ReSiELP process. For a comprehensive evaluation, the generated loads were compared with the potential environmental benefits gained thanks to the recovery of aluminium, at the largest extent.
This overview shows highly diverging results of existing PV LCAs - even for the same PV technology -, which can be explained by differences in inventory data (e.g. electricity mixes, material consumption and energy requirements), differences in system boundaries (e.g. inclusion or exclusion of balance of system (BOS), transport and end-of-life .
Improve panel, material, and process efficiency. Improving the energy generation efficiency of solar panels means that customers can generate more electricity from fewer panels—which would be easier on the wallet and would require less raw materials in the solar supply chain.
The carbon footprint of PV solar systems' was estimated in the range (14–73 g CO 2 -eq/kWh), which is lower than gas (607.6 CO 2 -eq/kWh) oil (742.1 CO 2 -eq/kWh), and coal-fired (975.3 g CO 2 -eq/kWh) power plants. Up to 50% lower GHG emissions can be achieved using new materials and/or recycled silicon material.
