PV panels will re-radiate most of this energy as longwave sensible heat and convert a lesser amount (~20%) of this energy into usable electricity. PV panels also allow some light.
Do large-scale photovoltaic plants cause unfavorable surface radiative effects?
As the installation of large-scale photovoltaic (PV) facilities in the barren area of Gonghe, China, would cover a substantial portion of the Earth's surface with PV panels, concerns exist about the extent to which PV plants induce unfavorable surface radiative effects from the change in land use.
Additionally, PV panel surfaces absorb more solar insolation due to a decreased albedo 13, 23, 24. PV panels will re-radiate most of this energy as longwave sensible heat and convert a lesser amount (~20%) of this energy into usable electricity.
In addition, it was reported that the locations range from forests to deserts, all through grasslands, farmlands might impact the environment. The previous literature review reveals a well-established environmental impacts assessment of the solar PV systems is crucial.
For instance, Nemet compared the reduction of the replacement of fossil fuels with PV power generation, in particular the increase in radiative forcing resulting from the increase in the albedo of PV panels, and found a reduced radiative forcing of roughly a factor of 30.
Could a large-scale PV power plant create a 'local climate'?
Installation of a large-scale PV power plant, consisting of many PV arrays, covering substantial portions of the Earth's surface with dark-colored, sunlight-absorbing panels would likely induce a “local climate” with particular radiative impacts.
PV panels will re-radiate most of this energy as longwave sensible heat and convert a lesser amount (~20%) of this energy into usable electricity. PV panels also allow some light energy to pass, which, again, in unvegetated soils will lead to greater heat absorption.
