HIGHLIGHTS
- Dual land-use systems, like agrivoltaics, allow for high land-use efficiency.
- Renewable energy sources reduces the carbon footprint.
- Solar eclipses have a significant impact on the production of electricity in PV power plants.
- Over a longer period of time, we can expect average values.

ABSTRACT
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.
