Are utility-scale photovoltaic plants affecting land-use impacts?
Abstract—The rapid deployment of large numbers of utility-scale photovoltaic (PV) plants in the United States, combined with heightened expectations of future deployment, has raised concerns about land requirements and associated land-use impacts.
How can PV panels be integrated into agricultural landscapes?
China has established clear regulations to ensure sustainable and harmonious integration of PV panels into agricultural landscapes. Land for PV is primarily acquired through lease agreements with relevant stakeholders, ensuring protection against the use of arable land.
How can agrivoltaics mitigate land-use impacts of utility-scale PV?
• While there are potentially other ways (such as “agrivoltaics”) to mitigate the negative land-use impacts of utility-scale PV, the primary way to mitigate the inevitability of rising land costs is to minimize the amount of land needed to generate each MWh of solar energy
These special types of land, often with harsh natural environment, low land utilization rate and abundant solar radiation, are more suitable for large area installation of PV facilities, with green energy to drive innovative applications and land transformation, to achieve simultaneous development of economic and ecological benefits.
Regardless of the method of calculation, it is evident that PV development will occupy a considerable amount of land resources. However, land represents a finite natural resource in China, with mountains, plateaus, and hills constituting approximately 69 % of the total land area, while flat land makes up the remaining 31 % .
Additionally, this research initially assumed that different land use types would not significantly impact PV electricity generation. However, real-world scenarios may differ. For instance, vegetation on cropland could shade the PV panels, affecting their output.
