“…Furthermore, factors affecting societal acceptance of these new applications need to be studied. From the project implementation perspective, APV systems are challenging because they strongly interact with agriculture, the local economy, and the stakeholders on-site [31]. The APV systems are costlier than groundmounted PV systems.…”

In the literature, many studies outline the advantages of agrivoltaic (APV) systems from different viewpoints: optimized land use, productivity gain in both the energy and water sector, economic benefits, etc. A holistic analysis of an APV system is needed to understand its full advantages. For this purpose, a case study farm size of 0.15 ha has been chosen as a reference farm at a village in Niger, West Africa. Altogether four farming cases are considered. They are traditional rain-fed, irrigated with diesel-powered pumps, irrigated with solar pumps, and the APV system. The APV system is further analyzed under two scenarios: benefits to investors and combined benefits to investors and farmers. An economic feasibility analysis model is developed. Different economic indicators are used to present the results: gross margin, farm profit, benefit-cost ratio, and net present value (NPV). All the economic indicators obtained for the solar-powered irrigation system were positive, whereas all those for the diesel-powered system were negative. Additionally, the diesel system will emit annually about 4005 kg CO2 to irrigate the chosen reference farm. The land equivalent ratio (LER) was obtained at 1.33 and 1.13 for two cases of shading-induced yield loss excluded and included, respectively.

“…The development of photovoltaic agriculture takes into account the development of photovoltaic industry and agriculture, thereby optimizing the structure of energy industry and agriculture. Photovoltaic agriculture can generate clean electricity, thereby alleviating the contradiction between supply and demand of clean energy [ 51 ] and ensuring energy security [ 52 ]. Therefore, the influencing factors of social niche include promoting the development of smart agriculture, optimizing the structure of energy industry and agriculture, alleviating the contradiction between supply and demand of clean energy, and ensuring energy security.…”

To explore the niche improvement path of photovoltaic agriculture in China, a niche influencing factor system was constructed first. Then, this study innovatively combined the DEMATEL and analytic network process (DANP) method and the NK model, which can correct the defects of the traditional NK model. Based on the above method, the influence coefficients and index weight of each niche factor were calculated, and the niche fitness landscape of photovoltaic agriculture was constructed. Finally, according to the fitness landscape map of each combination state, the optimal configuration state of niche influencing factors of photovoltaic agriculture and the optimal niche improvement path of photovoltaic agriculture were explored. We found that the interaction between the six niche influencing factors determines the niche fitness of photovoltaic agriculture, and the changes in the niche fitness and the niche improvement of photovoltaic agriculture are coordinated. It was proposed that the optimal niche improvement path of photovoltaic agriculture in China is “technological innovation → policy formulation → resource allocation → economic improvement → social recognition → environmental protection”, and the research conclusions were further explained and discussed.

“…At the same time, light resources are also indispensable, because it is necessary resources for “photosynthesis” and the “photovoltaic effect”. In addition, the continuous growth of the population, the lack of resources, and environmental deterioration make the combination of photovoltaic agriculture have a broad market [ 42 ]. The emergence of photovoltaic agriculture can alleviate the above contradiction between grain production and photovoltaic power generation for land resources.…”

“…Photovoltaic agriculture also meets the human demand for energy and food, and promotes the structure optimization of the energy industry and agriculture. In addition, the emergence of photovoltaic agriculture solves the demand for photovoltaic power generation for land resources, which can produce more clean energy and alleviate the demand for energy, especially clean energy [ 42 ]. Also, photovoltaic agriculture can promote food security.…”

To evaluate the ecological niche of China’s photovoltaic agriculture, this paper firstly analyzed the composition of photovoltaic agriculture and constructed the ecosystem of photovoltaic agriculture. Then, we defined the concept of the ecological niche of photovoltaic agriculture, and based on this the preliminary niche evaluation index system was constructed. Further, redundant indicators in the preliminary index system were deleted based on the rough set theory, and the final niche evaluation index system was constructed. Finally, the ecological niche of photovoltaic agriculture was evaluated using the DANP method and cloud model. We found that the niche level of China’s photovoltaic agriculture is between low and medium levels. Specifically, the level of resource niche is the highest, between medium and high levels; following is policy niche, near medium level; then is environmental niche, which is at a slightly lower medium level; the last three in turn are technology niche, social niche and economic niche. The technology should fully realize the synergistic effect of photovoltaic power generation and agricultural production, and the policy should play better environmental, social and economic functions on this basis to achieve a higher niche level of China’s photovoltaic agriculture.
