Shading effect and energy-saving potential of rooftop photovoltaic

The shading effect of the photovoltaic panels makes the roof temperature in the shading area higher than that in the unshaded area. This is because the photovoltaic panels store a certain amount of heat during the day when the irradiation is abundant, radiating heat with the shading area at night, causing its temperature to rise.

Modeling and analyses of energy performances of photovoltaic

The nature of PV greenhouse is to convert solar energy into the energy form that can be used by human, i.e. chemical energy (photosynthesis) and electric energy (photovoltaic effect). However, the intrinsic efficiency of the photosynthetic process is only around 3%, which is much lower than the conversion efficiency of typical commercial PV modules (around 20%).

Comparative analysis on the effectiveness of green roofs and

Photovoltaic (PV) panels and green roofs are considered as the most effective sustainable rooftop technologies at present, which utilizes the effective rooftop area of a building in a sustainable manner. To assess the most suitable rooftop technology out of the two, it is vital to have an idea on the energy savings potential of these sustainable rooftop technologies,

Photovoltaic solar electricity for greenhouses

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.

Morphology, yield and quality of greenhouse tomato cultivation

The installation of photovoltaic panels on the greenhouse roof occupied only 9.8% (of the cover). Two publications were made of this research. In the first publication, Ureña-Sánchez et al.

Morphology, yield and quality of greenhouse tomato cultivation

In contrast, these differences disappear under moderate shading (40–50%) (Callejón-Ferre et al., 2009; Klaring and Krumbein, 2013); however, in the present study, 9.8% shading by photovoltaic panels mounted on the greenhouse roof produced significantly more TSS than did the control without photovoltaic panels, coinciding with that indicated by Lorenzo et al.

An algorithm for calculating the shade created by greenhouse

Integration of photovoltaic modules into greenhouse roofs is a novel and intriguing method. The cost of products grown in production system using solar radiation such as a photo-voltaic system is essentially based on the intensity of the shading effect of PV panels on crops inside greenhouses.
