Use of the ND tool: An open tool for the synthetic generation of 1-min solar data from hourly means with geographic flexibility
(American Institute of Physics, 2022)
In this paper, we present a description of how to use a web based tool employing the ND model by Larrañeta et al. [1]. The tool is suited for downscaling DNI, GHI or coupled DNI and GHI from 1-h to 1-min. It requires only ...

Cloud transient characterization in different time steps
(American Institute of Physics Inc., 2017-06)
In this paper we evaluate the cloud transients by analyzing the dynamics of the direct fraction index kb for one year of solar radiation data in different time steps. We use instant 5-sec data integrated data and compare ...

Economical and environmental analysis of thermal and photovoltaic solar energy as source of heat for industrial processes
(American Institute of Physics Inc., 2017-06)
Thermal energy for industrial processes can be generated using thermal (ST) or photovoltaic (PV) solar energy. ST energy has traditionally been the most favorable option due to its cost and efficiency. Current costs ...

A normalized variability index of daily solar radiation
(American Institute of Physics Inc., 2020-12)
The Variability Index (VI) is widely used to quantify the intra-day solar radiation variability. It compares the length of the global horizontal irradiance (GHI) or direct normal irradiance (DNI) profiles with the length ...

Conditions in which a photovoltaic system is more viable than a low-temperature solar thermal system.
(EUPVCEC, 2016)
Photovoltaic (PV) and low-temperature solar thermal (LT-STH) are the most widely used technologies in the building sector. This study determines, depending on the most influential parameters, the conditions in which a PV ...
