This paper aims at improving the clarity and coherence of PV (photovoltaics) technical potential assessment, that is, calculation of the electricity that can be supplied by large-scale deployment of PV syste.

How much land area does a photovoltaic need?
We find that conventional photovoltaic will require 0.5 to 1.2% of global land area to meet projected energy demands by 2085 without accounting for climate change effects. When considering climate impacts, this requirement increases to 0.7–1.5% of the global land area.
How much land use does a PV system need?
4.2 We assume the capacity-weighted average land-use requirements (as reported in Table 4) for PV systems smaller than 20 MW when evaluating the impact of tracking arrays: 5.5 acres/MWac for fixed-tilt systems, 6.3 acres/MWac for 1-axis tracking systems, and 9.4 acres/MWac for 2-axis tracking systems.
Do solar and wind power have land-use requirements?
Rising shares of wind power and solar power in energy systems raises concerns overtheir land-use requirements (LURs) and associated impacts. Although abundantliterature is available on LURs of solar and wind power, existing estimates exhibit alarge variance, if not even inconsistency.
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 much land do solar power plants use?
For direct land-use requirements, the capacity-weighted average is 7.3 acre/MWac, with 40% of power plants within 6 and 8 acres/MWac. Other published estimates of solar direct land use generally fall within these ranges.
