Offering “turnkey” working systems in place, we are able to provide a complete spectrum of services for projects from viability studies to commissioning.
About 84% or even more of the total energy consumption and total GHG emission occupied during the PV manufacturing process. The solar grade silicon (SoG-Si) production is the most energy-consuming and GHG-emitting process, which accounts for more than 35% of the total energy consumption and the total GHG emission.
With technology advancement in the future, both energy payback times and GHG emissions are expected to decrease further. Regardless multi-Si, mono-Si, LS-PV or distributed PV system, PV station manufacturing is responsible for about 84% or even more of total energy consumption and GHG emissions.
Thus, the energy consumption of SOG-Si manufacturing can be saved. It is assumed that the recovery rate of both steel and aluminum used for the supporting structure is 100%. The other substances, such as plastic and circuit boards, are regarded as hazardous waste, the comprehensive utilization rate of them is 45.4% .
What mainly causes the above results is that the whole life cycle of PV power generation consumes large amounts of electricity and water. The coal-fired power generation consumes a large amount of PED and causes a lot of environmental emissions. And a lot of water consumption will lead to higher industrial water consumption and generate more COD.
Photovoltaic (PV) power generation is commonly regarded as one of the most promising renewable energies due to its tremendous capacity and potential to reduce energy consumption and henceforth decrease pollution , .
