Effect of diffuse solar radiation on the thermal performance of solar collectors

open access: yesCase Studies in Thermal Engineering, 2018
To characterize the thermal performance of solar thermal collectors, lab tests are required to evaluate the maximum thermal efficiency and heat loss. The CNS 15165–1:2008 is in compliance with ISO 9806:1994, which is an outdoor steady-state test method ...

An Analysis of Global, Direct and Diffuse Solar Radiation

open access: yesEnergy Procedia, 2015
AbstractThe paper studies the horizontal global, direct-beam and sky-diffuse solar radiation data measured in Hong Kong from 2008 to 2012, reports some of the general findings, evaluates mathematical model for predicting direct-normal solar radiation and computes various climatic variables.

Long-term variations in solar radiation, diffuse radiation, and diffuse radiation fraction caused by aerosols in China during 1961-2016.

open access: yesPLoS ONE, 2021
The effects of atmospheric aerosols on the terrestrial climate system are more regional than those of greenhouse gases, which are more global. Thus, it is necessary to examine the typical regional effects of how aerosols affect solar radiation in order ...

Estimation of the Hourly Global Solar Irradiation on the Tilted and Oriented Plane of Photovoltaic Solar Panels Applied to Greenhouse Production

open access: yesAgronomy, 2021
Agrometeorological stations have horizontal solar irradiation data available, but the design and simulation of photovoltaic (PV) systems require data about the solar panel (inclined and/or oriented).

Impact of diffuse solar radiation on HAM simulation accuracy [PDF]

open access: yesMATEC Web of Conferences, 2019
Advance in the numerical simulation models brings higher need for more accuracy outdoor boundary conditions - climate data sets. With influence of the urban heat islands, measured climate on the meadows, far from pawed surfaces creates uncertainty in the
