6 FAQs about [Photovoltaic greenhouse support specifications]
What is the energy performance of a PV greenhouse?
Generally, the energy performance of a PV greenhouse contains not only PV electricity production and interior irradiance, but also the thermal behavior, plant production, and electricity consumption. The model can be made even more comprehensive by including e.g. Computational Fluid Dynamics (CFD) models and crop models . 5. Conclusions
What is a solar photovoltaic greenhouse?
The solar photovoltaic greenhouses are enclosures in which temperature, humidity and other environmental factors are kept help to promote agricultural crops. They are always located on open sites where roof can receive enough amounts of direct solar irradiation to generating electricity.
What is a self-powered PV greenhouse?
A well-designed PV greenhouse can achieve the internal energy balance, i.e. the photovoltaic power generation is capable to cover the total energy consumption of daily operation, or even have extra electricity that can be sold to the electric power company. Such an ideal self-powered greenhouse can be called as “zero-energy greenhouse” .
Can photovoltaics be used on a greenhouse roof?
The design of such systems has a dual purpose: on the one hand, the use of PVs on greenhouse roof do not reduce crop production; on the other hand, achieving the lowest final cost of energy produced with the smallest possible environmental footprint. A common option is to use a combination of a geothermal heat pump with photovoltaics.
How to regulate the daily operation of the PV greenhouse?
Four sun-tracking methods (closed, quasi-perpendicular sun tracking, no-shading, and open) are proposed to regulate the daily operation of the PV greenhouse with determined PV layouts. Dynamic positions of PV modules by different sun-tracking methods are derived as the functions of the solar positions.
What is a solar power plant for a greenhouse?
A solar power plant for a greenhouse is a particular application of solar energy technologies for agricultural enterprises, farms, and holdings. Modern agricultural companies are increasingly using solar power plants as a long-term investment that can significantly reduce production costs and increase their competitiveness.
