Can photovoltaics be used in greenhouses?

The integration of photovoltaics (PV) into greenhouses is analyzed. Greenhouse energy demands, PV performances and effects on crop growth are reported. The application of organic, dye-sensitized and perovskite solar cells is described. The new PV technologies can promote sustainable, self-powered and smart greenhouses.

Are solar panels suitable for greenhouses?

This study presents a survey and evaluation of photovoltaic (PV), solar thermal collectors (STC), and photovoltaic/thermal (PV/T) solar technologies for greenhouses. PV modules show promising results to cover the electrical energy demands and ensure adequate crop production.

Can traditional PV systems be used for greenhouse application?

The use of traditional PV systems for greenhouse application has to take into account their integration on existing structures and glazing, as well as the trade-off between PV and plant requirements for the respective electrical and crop production.

What is a PV greenhouse?

Conventional PV modules are integrated into the greenhouse roof, similar to the roof of a building, to provide electrical energy. For example, in arid and semi-arid regions, where cooling is mandatory, such as Mexico, a fan and pad cooling system’s demands were met with a PV greenhouse ( Romantchik et al., 2017 ).

How can PV technology improve the sustainability of greenhouses?

The new PV technologies can promote sustainable, self-powered and smart greenhouses. Reducing the energy demand and dependency on fossil fuels is crucial for improving the sustainability of greenhouses, which are the most energy intensive systems in the agricultural sector.

Are static PV solar modules a good option for greenhouse crops?

PV modules show promising results to cover the electrical energy demands and ensure adequate crop production. However, the main issue with static conventional PV solar modules is the shading effect that causes a reduction in the photosynthetic efficiency of greenhouse crops.
