Are photovoltaic systems a good option for a greenhouse?

Improvements in photovoltaic electricity systems are making them more attractive for greenhouses. Photovoltaic systems with efficiencies as high as 40 percent are now available at a cost that results in a reasonable payback. Also, systems that can be integrated with the greenhouse are being installed. Let's look at some of the options.

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.

Are organic photovoltaics a smart greenhouse?

Hence, a smart greenhouse with semi-transparent organic photovoltaics (OPVs) integrated into the power-generating roof is highly desirable for modern agriculture 2, 3. Due to the unique band structure of organic materials, OPVs are able to selectively absorb light with a desired wavelength 4, 5, 6.

Are flexible/lightweight PV modules a good choice for buildings & greenhouses?

A closer look at the literature on PV shows that there is a dearth of studies which place emphasis on PVs with lightweight BOS systems, highlighting the importance of flexible/lightweight PV modules for buildings and greenhouses.

Do solar greenhouses have a transparent envelope?

Solar greenhouses are mainly made of a transparent envelope and the effect of the direct and diffuse component of solar radiation impacts the internal plant well-being. This study aims to identify the best solution of a transparent envelope on locations with different latitudes and evenly distributed around the globe.

How does a PV system work in a greenhouse?

Grid connected systems are the most common for greenhouses. When excess power is being generated, the grid absorbs this. At night when there is no generation, the grid supplies the needed power. This is net metering. As PV systems supply direct current, it has to be converted to alternating current to operate the greenhouse equipment.
