A b s t r a c t. In connection with renewable energy sources, the courtyards of the buildings provide space for the installation of agrivoltaics for sustainable development. This paper proposes the use of courtyards of low-rise buildings for agrivoltaics. This will increase the area for installing photovoltaic systems, which have so far only been installed on roofs or facades or on open fields. The advanced design of the photovoltaic systems will enable the dual use of the area both for the cultivation of crops and for the production of electricity at the same time. The increased amount of electricity produced in photovoltaic systems also contributes to reducing the carbon footprint. On the courtyard as well as on the open fields, it is possible to grow agricultural crops between rows of photovoltaic panels. The partial shading of seedlings during summer sunny days reduces their heat stress and slows down soil drying. Solar eclipses are rare, but their impact on electricity generation is significant. We evaluated the measured data and we assessed the electricity production and the influence of a solar eclipse on the electricity production in photovoltaic power plants in the Czech Republic. The daily loss in production depends on the size of the eclipse. A comparison of the annual electricity production in two selected PV power plants with the expected values according to PVGIS testifies to the quality of the construction and the PV panels used in both power plants.K e y w o r d s: Agrivoltaics, carbon footprint, heat stress, photovoltaic system, solar eclipse

“…Furthermore, the economic viability of solar power plants is influenced by their real lifetime and performance. Despite manufacturers data, empirical evidence suggests that the actual lifetime of PV power plants [ 38 ] and their performance efficiency [ 39 ] falls short of expectations, particularly in regions with tropical climates. This discrepancy underscores the importance of robust and reliable energy generation systems, such as hybrid solar-MGT systems, which offer not only environmental benefits but also economic advantages through enhanced durability and performance.…”

“…Other indices are based on the standard of self-sufficiency, such as the self-consumption ratio (SCR) or the self-sufficiency rate (SSR). Further indices consider a proportion of the energy-consumer demand that is met locally, or the time needed to recover the initial investment of the project, as the simple payback time (SPBT) [31]. Also, we have the levelized storage cost (LCOS), which includes the total energy drawn from storage considering the cost of charging cost [32], or the levelized cost of energy (LCOE), which comprises costs that occur during the useful life of the project.…”

Suitability Index for the Placement of Solar Plants Based on Inequality Measurements and on Satellite Images

The selection of a certain location for the placement of a solar facility depends on the solar resource availability, which is generally assessed though exceedance probabilities. However, the choice of the specific exceedance probability is arbitrary and the assessment will be different depending on the choice taken. Furthermore, exceedance probabilities do not reflect seasonal variability, which affects radiation availability. Therefore, in this work we present a new index, the suitability index based on Theil (SIT), which allows us to assess with a single value the degree of suitability of a site for installing a solar plant. Obtained from the Theil index, it considers the availability of the resource and its seasonal variability, based as it is on the proportion of the given radiation in each month. As we will see, the new index is clearly more sensitive to the amount of radiation expressed in terms of the 50th percentile than to the variability, as given by the interquartile range. This is a quality to be pondered since scarcity of radiation will always be a greater disadvantage for a solar installation than high variability. The results obtained in the study, grounded in the application of satellite images, show that the index adequately reflects the radiation characteristics in the study area. The territory is broken into areas associated with such characteristics through a cluster analysis, so that geographical and economic elements can be considered when choosing the final location for a solar installation. Furthermore, the new index may include the effects of energy storage during the months in which a certain demand is exceeded.
