“…The simulations carried out clearly show the advantage of such a solution in relation to classic PV modules. The rough / textured surface of the PV modules reduces solar reflection (Flizikowski & Mroziński, 2016;Riley & Olson, 2011;Yu Bin Zhu, 2018).…”

Large PV installations are being built increasingly often in areas close to airports in Poland and around the world. These are not only roof installations but also large PV farms, allowing not only the supply of the energy for the airport itself but also the ability to sell the excess energy produced. The applied PV installations may cause in some cases negative impact in the form of e.g., electromagnetic fields and light reflections which may limit the visibility of pilots and air traffic controllers. The article presents an overview of various negative impacts of PV farms on the workings of an airport and the main factors influencing the occurrence of certain threats have been diagnosed. An assessment of the usefulness of the tool and method for simulation and the reduction of possible negative impacts is also presented.

“…In addition, aviation crashes commonly cause fatal results. The SG can influence pilots and ground workers from A-PVs when a flight is in landing, take-off, and taxiing on a runway [14]. The altitude of an airplane is sufficiently low near airports so that the SG from A-PVs can reach the pilots' eyes.…”

Photovoltaic modules and systems (PVs) play an important role in achieving self-sustainable airports. In particular, airport-based PVs (A-PVs) have access to their full potential because airports are typically located in open spaces. However, the reflection of solar light by A-PVs’ front glass is unavoidable and may cause an accident due to solar glare (SG). In this study, we theoretically calculated the risk of SG from A-PVs depending on their azimuthal installation orientation (θPV) and derived a general design rule for minimizing the SG. The simulation reveals that the SG from A-PVs facing the runway and potential flight path causes after-images in pilots and ground workers throughout the year (>800 h/year). On the other hand, modifying their θPV, facing opposite runways and flight paths, significantly reduces the SG (<1 h/year) by reflecting the incident light outside the aircraft route. Although the θPV is not southward, their annual energy generation with an optimized θPV decreases by only 5–7% compared with A-PVs facing southward. This universal design approach is verified at four other airports, confirming the model’s validity. We believe our study will contribute to more solar light harvesting at airports without glare hazards.
