Abstract
The photovoltaic greenhouses are mixed systems, combining the electricity and the agricultural production in the same surface area.
Moreover, the photovoltaic greenhouse conserves all the properties of a conventional greenhouse, but in addition it offers the possibility of producing and reselling electricity.
The presence of the photovoltaic panels on the roof reduces the solar radiation received inside the greenhouse.
However, the consequence of such decrease in the incident radiation on the fruit production and the greenhouse climate is still being discussed within this kind of agrosystem.
In this context, the aim of the present study is to assess the impact of the shadow caused by the photovoltaic panels on the microclimate and the tomato yield in the Canarian greenhouse.
Experimental measurements were carried out in experimental Canarian type greenhouse covered with flexible photovoltaic panels on 10% of its total roof area.
The PV panels were mounted on the roof in a checkerboard arrangement.
We have chosen this configuration because it improves the spatial distribution of the solar radiation received inside the greenhouse.
Results illustrate that 10% roof coverage rate by the flexible PV panels arranged in checkerboard pattern, does not have a significant effect on the microclimate and tomato production under canary greenhouses in the southern Mediterranean climate.
