However, if crops are planted or grass grows under the solar power system, they absorb some of the sunlight while also evaporate water, which cools the solar panels. Most research has found that vegetables that
Increased panel efficiency due to cooling: the cooling effect of the water close to the PV panels leads to an energy gain that ranges from 5% to 15%. [6] [32] [33] [34] Natural cooling can be increased by a water layer on the PV modules or
Tomato, lettuce, pepper, cucumbers and strawberries are the most studied crops under PV panels (Fig. 5). The recent literatures for applications of selective shading systems on the aforementioned crops and others plants are reviewed in the following sections.
Ultimately, total fruit production was twice as great under the PV panels of the agrivoltaic system than in the traditional growing environment. Fig. 3: Plant ecophysiological impacts of colocation of agriculture and solar PV panels versus traditional installations.
Associating food crops and solar PVon the same land area which is referred as agrivoltaic systems (also denoted as Agrophotovoltaics, APV) (Dinesh and Pearce 2016; Santra et al. 2017) is among the most developing techniques in agriculture that attract significant researches attention in the past ten years (Fig. 1 a).
Researchers in South Korea have been growing broccoli underneath photovoltaic panels. The panels are positioned 2-3 metres off the ground and sit at an angle of 30 degrees, providing shade and offering crops protection from the weather.
Agrivoltaic farming could be a solution to not just one but both of these problems. It uses the shaded space underneath solar panels to grow crops. This increases land-use efficiency, as it lets solar farms and agriculture share ground, rather than making them compete against one another.
Consequently, the impact that solar panels could have on crop yield and fruit quality has attracted great attention of researchers. Tomato, lettuce, pepper, cucumbers and strawberries are the most studied crops under PV panels (Fig. 5).
