3.5.2. PV in Wasteland

The Pomerania Voivodeship has a large area of wasteland, with a total area of 41.2 thousand ha [80]. It was assumed that 20% of the wasteland in the Voivodeship will be subjected to reclamation in the "energy direction", where PV farms will be erected. The calculations took into account the insolation and solar irradiance of individual areas of Poland (data from the Institute of Meteorology and Water Management), and then the

amount of electricity that can be obtained from PV panels with an efficiency of 15% was calculated, using the following formula [55]:

$$\mathbf{E\_W} = \mathbf{0.20} \cdot \mathbf{0}.15 \cdot \mathbf{P} \mathbf{n} \cdot \mathbf{I} \cdot \mathbf{S\_\prime} \tag{15}$$

where: Ew—electricity that can be obtained annually from PV in wasteland (J/year), Pw— wasteland area (m2), I—insolation (h/year), converted to (s/year), N—solar irradiance (W/m2).

The amount of electricity generated from PV will be 1.14 TWh (4120 TJ).
