“…Cross-interaction of produced pollen during the flowering period and air contamination causes an increased pollen allergies [61]. A similar problem also affects PV panels, where the action of various types of dust (such as cement, sand or mud from the topsoil) reduces their efficiency [62,63]. Pollen can also be a seasonal soiling problem affecting PV performance [64].…”

The intensive exploitation of natural resources, expansion of human population and degradation of natural and semi-natural habitats, caused among others by agriculture, forestry and urbanisation, enforce special care for the natural resources, especially the disappearing types of vegetation that are refugees of biodiversity. One of the most threatened plant communities are grasslands (pastures and meadows), which has suffered the most in recent decades due to the intensification of agriculture and the transformation of land use. The purpose of this paper is to propose a hybrid approach to clean energy production on photovoltaic (PV) farms, taking into account the needs of grassland conservation and restoration. Nine sets of sciophilous species are proposed, including grasslands rich of pollinator benefits, grasslands with low pollen production to maintain high electrical efficiency of panels, and rich, standard meadows in wet (Molinion, Calthion, Alopecurion, Cnidion), fresh (Arrhenatherion) and dry (Cirsio-Brachypodion) types. The combination of clean energy and grassland conservation has been called ecovoltaics (EV) because it combines the production of renewable electricity with care for the diversity of valuable grassland ecosystems. The research will continue on an experimental ecovoltaic farm with innovative technical solutions to effectively maintain the desired meadow species composition. The purpose of this study was to analyse and select plant species that could be introduced into areas where PV cells are installed under climatic conditions in southern Poland. Using databases, environmental and ecological factors were taken into account. As a result of the study, a list of 206 species was selected that could be introduced to areas where they will coexist with PV panels, taking into account the effect of shading. The developed selection of these plant species provides a starting point for future work by botanists and engineers seeking to increase the biodiversity of sites where PV panels will be placed.

Photovoltaic modules are one of the renewable energy sources with great potential for application in various regions of the world as well as for different terrain. They are, however, sensitive to external factors, affecting the overall amount of energy generated, such as solar irradiance, shading effects and any form of soil build-up on the front glass cover of solar device. The latter issue happens over a course of weeks, months and years and the exact pace is determined for a specific location. Nevertheless, dust remaining on the module surface limits the amount of solar irradiation that can reach solar cells. It then leads to a lowered maximum power and correspond to a decrease in energy yield. A way to mitigate soiling effect, outside of natural washing dependent on precipitation, is a regular debris removal. The proposed methods utilise different approaches, namely active cleaning such as manual, mechanical or electrodynamic, or passive cleaning by applying additional hydrophobic or hydrophilic coating to slow down the accumulation tempo.
