Cím:Potential of the Agrophotovoltaic(APV) Technologies in Hungary / Chalgynbayeva, A., & Bai, A.
Dátum:2022
Megjegyzések:3rd AgriVoltaics Conference & Exhibition, held from June 15-17, 2022 online and in Piacenza, Italy.
Several large-scale PV systems are also operating in Hungary, which may support the future use of Agrivoltaics (APV) systems. As a combination of renewable energy and agriculture, APV facility agriculture has broad prospects in Hungary's future agricultural development. APV will be a new form of agricultural development in Hungary, which will in line with the policy of agricultural development in Hungary. This paper first discusses the development prospects of photovoltaic and photovoltaic installed capacity in Hungary from 2010 to 2020 and analyses the importance and trends of photovoltaic energy in the national energy production and its distribution in small-scale and large-scale PV systems in Hungary. On the basis of economics analysis, using the economic indicators such as additional investment costs, additional income and return on investment of APV systems compared to APV and PV systems, as well as APV and conventional apple production. Then, using the forecasting model and the simple linear regression model, the annual revenue of large-scale and small-scale PV power plants in Hungary was estimated based on the actual data selection of large-scale PV power plants in this paper. Therefore, this paper conducts in-depth research and potential analysis on the development of agrophotovoltaic industry, and put forward some reasonable opinions and measures, in order to further promote the integration depth of APV industry and agricultural industry, so as to improve the added value of agricultural production and economic effects of APV systems on land use in Hungary.

Cím:Economic potential of agrivoltaic systems for horticulture cultivation in Hungary / Chalgynbayeva, A., Bai, A.
Dátum:2023
Megjegyzések:Hungary currently has several large-scale photovoltaic (PV) systems in operation, which could potentially facilitate the implementation of agrivoltaic systems (AVS) in the future. As a hybridization of renewable energy and agriculture, AVS has significant potential in the advancement of agriculture in Hungary. The adoption of AVS in Hungary would be in accordance with the nation's agricultural development policy, introducing a novel approach to agricultural expansion. This paper first are discusses the development prospect of photovoltaic systems and photovoltaic installed capacity in Hungary from 2010 to 2020. We analyzed the importance and trends of photovoltaic energy in the national energy production and its distribution in small- scale and large-scale PV systems in Hungary. Based on the economic analysis of the large-scale Hungarian PV systems, on the Hungarian average number of sunshine hours and using the economic indicators such as additional investment costs, additional income and return on investment of AV systems compared in three aspects: AVS, PV systems and conventional apple production. The results from our horticulture study indicated that when we compare the AVS to the conventional apple production, the high value of produced electricity is enough to return the costly investment within reasonable time. Our findings suggest that it should be highlighted than robust technological development, and/or hiking agricultural prices, and/or significant state subsidy is needed for the further spreading of the AV systems.

Cím:Initial feasibility assessment of the economic viability of agrivoltaics in apple farming / Chalgynbayeva, A.; Balogh, P.; Szőllősi, L.; Gabnai, Z.; Apáti, F.; Sipos, M.; Bai, A.
Dátum:2024
Megjegyzések:Agrivoltaic systems (AVS) allow the simultaneous use of land-as a limited resource-for crop production and electricity generation. This paper introduces the development prospects of AVS in Hungary and provides insights into international trends. The most important part is a complex economic analysis and a unit cost analysis of a 38 MWp capacity AVS, considering the most typical basic data in electricity and apple production. The applied risk analysis is based on a Monte Carlo simulation, the distribution function, and probabilities. To introduce the economic facet of the competitiveness of AVS, a comparative analysis was carried out between AVS, ground-mounted photovoltaic (GM-PV) systems, and conventional apple production systems (ConAPS). In the most probable scenario, the AVS was financially attractive (NPV = 70 million EUR under 30 years). Our correlation analysis shows that feed-in tariff (FIT) price and the role of financing are considered the dominant economic factors. A favourable FIT price enhances the profitability of AVS; however, it makes GM-PV systems more profitable compared to AVS, so it negatively affects the competitiveness of AVS systems. AVS operations result in a more balanced unit cost of apples and electricity compared to the independent operation of GM-PV systems and ConAPS; in addition, it allows for land saving and more intensive land use.

Cím:Worldwide research trends in agrivoltaic systems : a bibliometric review / Aidana Chalgynbayeva, Zoltán Gabnai, Péter Lengyel, Albiona Pestisha, Attila Bai
Dátum:2023
ISSN:1996-1073
Megjegyzések:An agrovoltaic system combines agricultural crop production and energy production in the same place, emphasizing the dual use of land. This article provides a bibliometric analysis of agrivoltaic topics based on publications indexed in SCOPUS, in which either economic assessments of agrivoltaics, agrivoltaic systems for crops and livestock animals, photovoltaic greenhouse and agrivoltaics with open field are discussed, or its ideas are used to analyze certain locations. A bibliometric analysis was conducted using the SCOPUS database. Multiple bibliometric tools, such as R Studio and Biblioshiny, were applied to analyze data for this study. Finally, 121 relevant articles were obtained and reviewed. The results show that the focus topic is a brand-new research area, with the majority of relevant scientific publications concentrated in the last three years, and with much ongoing research. This is why AV-specialized scientific conferences might be the best place to get relevant and up-to-date information, with the highest number being offered in the USA and China. A typical trend in recent years has been researched, focusing on different agricultural aspects. The research results show that scientific publications in recent years mainly focus on short-term predictions, there is no recognized evaluation standard for various prediction analyses, and it is difficult to evaluate various prediction methods so far.

Megjegyzések:Over the years, energy is becoming an essential factor with an impact on social, economic, and environmental aspects. More than 2.5 billion people are connected to agriculture worldwide, so the importance of agricultural energy production has become increasingly important. This study provides a comprehensive review of renewable energy, environment, and farm publication trends. Two hundred articles from 1988 to 2022 were analyzed, with special attention devoted to the last three extreme years, using the Scopus database and the Bibliometrix tool for analysis and visualization. Research on this topic experienced significant developments after 2008, with many fluctuations being revealed. Historically, China and the USA were the most productive countries in agricultural energy production advancements. However, in the last three years, the research center`s respective contributions have undergone major changes. China maintained its dominance, but the importance of the USA fell sharply, and new centers (India, Poland) appeared. Biogas is the most popular method which is used and searched in this area between 1988-2022 since it includes both sustainability and locality. However, between 2020-2022, the importance of the circular economy has been highlighted in the literature. Complex energy systems, dual use of land, and energy storage might be the most important challenges for future research.
