Photovoltaic energy systems are considered to be clean and sustainable energy resources due to their wide distribution and easy deployment. However, the environment can still be impacted during the processes from the production to recycling of such systems.
Photovoltaic power systems, as part of the electricity supply, are directly affected by related carbon policies in terms of their energy efficiency and carbon emissions. Through policy guidance and constraints, it is possible to increase energy efficiency and decrease the carbon footprint associated with photovoltaic power systems.
In terms of cost–benefit analysis, the optimization of the photovoltaic power system’s production line scale is achieved through the analysis of the payback period of energy investments, greenhouse gas emissions, and the external costs associated with photovoltaic technology, leading to improved efficiency and reduced carbon emissions.
The extraction of raw materials for photovoltaic components is energy-intensive and emits greenhouse gases, contradicting low-carbon objectives. During the production process, particularly during high-temperature steps, significant amounts of carbon dioxide are emitted, contributing to the environmental burden.
Simultaneously, by optimizing battery components , concentrating techniques , and photothermal technologies , not only has the performance of photovoltaic power been improved, costs reduced, and conversion rates increased, but also energy consumption and carbon emissions have been decreased.
