Problems solved by technology

As far as the production process is concerned, the polysilicon production process will produce a large amount of toxic and harmful substances, and the waste materials such as waste water, waste gas, and waste residues generated during the production process cannot be effectively treated and utilized, causing serious pollution to air, water, land and other resources.
Even in the post-use recycling process, there is still the problem of waste pollution

Embodiment

[0068] The present invention will be further introduced below in conjunction with the accompanying drawings and application examples.

[0069] Such as figure 1 , as shown in 2, 3, 4, a method for calculating the carbon emissions of photovoltaic systems based on the idea of ​​the whole life cycle, including the following steps:

[0070] Step 1. Establish a photovoltaic system carbon emission model based on the full life cycle theory, that is, the total carbon emission C of the entire life cycle of the photovoltaic system tot , the unit is kg, see the following formula (1)

[0071] C tot =C 1 +C 2 +C 3 +C 4 +C 5 +C 6 (1)

[0072] Among them, C1 is the carbon emission in the raw material acquisition stage of the photovoltaic module, C2 is the carbon emission in the production stage of the photovoltaic module, C3 is the carbon emission in the transportation stage, C4 is the carbon emission in the construction stage, and C5 is the carbon emission in the maintenance stage....

Abstract

The invention aims to provide a photovoltaic system carbon emission calculation method based on full life circle ideology. The method is used for assessing the total carbon emission in a photovoltaic power generation process. The method is generated based on the situation that a photovoltaic power generation system has the said problems, and aims to obtain the carbon emission generated within a full life circle of the photovoltaic power generation system through calculation according to the life cycle assessment analysis standard. By use of the method, the energy demand, raw material utilization and waste discharged to the environment as a result of all activities within the life cycle of the system can be assessed more comprehensively. According to the method, the carbon emission of the photovoltaic system within the whole life cycle from ''cradle'' to ''tomb'' is calculated comprehensively, and the influence of the carbon emission on the environment is researched; the defect of an existing photovoltaic system assessment system is overcome, and the limitation of photovoltaic system assessment is avoided.

Description

technical field [0001] The invention relates to a photovoltaic power generation system, in particular to a method for calculating and counting carbon emissions in the life cycle of each part of the photovoltaic power generation system. Background technique [0002] At present, photovoltaic power generation has become a hot technology in new energy due to its flexibility and sustainability, and scientific and technological progress has also made photovoltaic power generation technology widely used in various conventional and special fields. However, although solar energy is clean energy and does not generate carbon emissions when used, this may not be the case from the perspective of the entire life cycle of photovoltaic systems. Due to reasons such as backward technology and irregular policies, the solar energy industry has serious environmental pollution problems in China. As far as the production process is concerned, the polysilicon production process will produce a larg...
