About this Research Topic
Since solar energy is available everywhere, agricultural greenhouses, which are often built in remote and rural areas where no electric energy is available, can greatly profit from solar-to-thermal & solar-to-electric power conversion. Major challenges relate to the control of the greenhouse internal environment, especially in hot and cold regions of the world. As environmental control represents the higher contribution to the overhead operating costs, more efficient and less expensive solar technologies are requested, also to increase the share of renewable energy. This Research Topic is therefore looking for innovations of solar cooling, solar heating, lighting, and irrigation systems in greenhouses, by integrated Photovoltaic (PV)/ Thermal Photovoltaic (PVT) to improve their management and control systems.
Heating and cooling systems are major costs involved in greenhouses operation. Heating is usually provided by burning fossil fuels, which increases carbon dioxide emissions and environmental pollution. Furthermore, the prices of fossil fuels are rising rapidly. On the other hand, the utilization of solar energy has grown due to both technological improvements and governmental policies supportive of renewable energy development and utilization. The goal of this Research Topic is therefore to collect new studies on the state of the art of solar energy technologies for cooling, lighting, irrigation and heating of greenhouses, with the overall aim of decreasing emissions, energy consumption, and greenhouse operation costs.
This Research Topic welcomes submissions related, but not limited, to the following areas:
• Greenhouse integrated Photovoltaic (PV)/ Thermal Photovoltaic (PVT) to generate electric and thermal energy for Greenhouse environmental control systems.
• Greenhouse integrated Flat Plate Collectors (FPCs), Evacuated Tube Collectors (ETCs), solar concentrators, and their synergy to fulfill Greenhouses heating requirements and overcome limitations of pure solar collectors
• Solar thermal collectors in moderate climatic conditions to provide heating demand in greenhouses.
• Improvements in solar technology for solar water pump
Keywords: PV and PVT Greenhouses, Greenhouse integrated flat plate collectors, FPCs, Greenhouse integrated evacuated tube collectors
