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 ...

A novel storage system for cooling stand-alone photovoltaic installations
(Elsevier, 2020-08)
Stand-alone photovoltaic systems usually use batteries to adjust energy yield to energy demand. An alternative energy storage system for stand-alone photovoltaic installations is proposed for three cooling applications: ...

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 ...

Impact of the intra-day variability of the DNI on the energy yield of CSP plants
(American Institute of Physics Inc., 2019-07)
The operation and the electricity yield of CSP plants in two days with the same daily-accumulated DNI, even with the same Aperture Normal Irradiance (ANI) can be very different depending on other parameters such as the ...

Comparison of the representativeness of solar radiation type of days from the viewpoint of the production of parabolic trough and central receiver plants
(American Institute of Physics, 2022-05)
The classification of days according to the solar radiation features is one of the tools frequently used for the solar resource assessment, modelling or forecasting. Recent studies discuss the appropriate classification ...

Process Heat Generation Potential from Solar Concentration Technologies in Latin America: The Case of Argentina
(MDPI, 2017-03-17)
This paper evaluates the potential of solar concentration technologies—compound parabolic collector (CPC), linear Fresnel collector (LFC) and parabolic trough collector (PTC)—as an alternative to conventional sources of ...

An improved model for the synthetic generation of high temporal resolution direct normal irradiation time series
(Elsevier, 2015-12)
Several studies have confirmed the relevant impact of the resolution and frequency distribution of solar radiation data on the results of detailed production models. Many of the available direct normal irradiance (DNI) ...

Assessment of a Global-to-Direct empirical model for the long-term characterization of Direct Normal Insolation
(Elsevier, 2014)
The statistical characterization of the solar resource (direct normal solar radiation) is a key point in the initial phases of a solar thermal electricity (STE) plant project. Ideally, this characterization should be based ...
