Cloudiness Characterization in Seville Using Ceilometer Measurements
(AIP Conference Proceedings, 2020)
Laser Ceilometers make use of the elastic LIDAR by emitting signals vertically in the atmosphere and analyzing the profile of the backscattered signal to detect clouds and calculate cloud-base height [1]. Due to the high ...

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 ...

Identifying periods of clear sky direct normal irradiance
(Elsevier, 2017)
When modeling the effect of the cloud transients in the Direct Normal Insolation (DNI), it is particularly relevant to identify those moments in which there are no clouds between the observer and the sun. In this paper, ...

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 ...

The variable geometry central receiver system concept. First results and comparison with conventional central receiver systems
(Elsevier, 2014)
In line with the global trend for improving efficiency of existing solar power plants, the CTAER has developed and built a variable geometry central receiver facility, in which the solar field rotates around the tower ...

Thermodynamic Limits of the Use of PCM Simultaneously in Photovoltaic Modules and in Building
(EUPVCEC, 2013)
The paper quantifies the thermodynamic limits on the energy and exergy use that would result from the use of PCM in photovoltaic BIPV modules versus not using PCM, by limiting module temperature to 298 K and the thermal energy ...

Influence of Dust in Solar Cells Used for Measuring Solar Radiation
(EUPVCEC, 2013)
The photovoltaic cells (PV) are commonly used as global radiation measurement device, even though when it has been proved that there are significant differences with respect to using pyranometers. The dirt deposited on ...
