An Experimental Investigation on Photovoltaic Array Power Output Affected by the Different Partial Shading Conditions

Energies, 2021
This paper presents an experimental investigation on photovoltaic array (PV array) power output affected by partial shading conditions (PSCs). An experiment setup of a PV array with a series configuration using 2 × 4 photovoltaic modules (PV modules) was

Small-scale human-biometeorological impacts of shading by a large tree

Open Geosciences, 2016
This study provides evidences on the beneficial small-scale human-biometeorological effects of a large shade tree during the daytime in summer. We carried out detailed measurement from 10 am to 6 pm with two human-biometeorological stations on a popular ...

Agrivoltaic System and Modelling Simulation: A Case Study of Soybean (Glycine max L.) in Italy

Horticulturae, 2022
Agrivoltaic systems (AV) combine agricultural activities with the production of electricity from photovoltaic (PV) panels on the same land area. The concept of AV systems was introduced in 1982 by Goetzberger and Zastrow, but only more recently have the ...

Growth and Leaf Gas Exchange Upregulation by Elevated [CO₂] Is Light Dependent in Coffee Plants

Plants, 2023
Coffee (Coffea arabica L.) plants have been assorted as highly suitable to growth at elevated [CO2] (eCa), although such suitability is hypothesized to decrease under severe shade.

Shading Contributes to the Reduction of Stem Mechanical Strength by Decreasing Cell Wall Synthesis in Japonica Rice (Oryza sativa L.)

Frontiers in Plant Science, 2017
Low solar radiation caused by industrial development and solar dimming has become a limitation in crop production in China. It is widely accepted that low solar radiation influences many aspects of plant development, including slender, weak stems and ...

Effects of Low Light after Heading on the Yield of Direct Seeding Rice and Its Physiological Response Mechanism

Plants, 2023
As a photophilous plant, rice is susceptible to low-light stress during its growth. The Sichuan Basin is a typical low-light rice-producing area. In this study, eight rice varieties with different shade tolerances were studied from 2021 to 2022.

Shade Avoidance [PDF]

The Arabidopsis Book, 2012
The presence of neighboring vegetation modifies the light environment experienced by plants, generating signals that are perceived by phytochromes and cryptochromes. These signals cause large changes in plant body form and function, including enhanced growth of the hypocotyl and petioles, a more erect position of the leaves and early flowering in ...

Modified cosine-quadratic reflectance model

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska
In the article, a new light reflectance model is proposed. The model is based on the modified cosine-quadratic bidirectional reflectance distribution function. The concept of bidirectional reflectance distribution function is analyzed. The disadvantages
