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 ...

Performance of factory made solar heating systems according to standard ISO 9459-5:2007
(Elsevier, 2019-01)
The utilization of solar energy based technologies has attracted increased interest in recent times in order to satisfy the energy demands in buildings. This research work presents a comparative analysis of the 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 ...

Experimental Comparison of Different Global Irradiation Models with and without Sun Tracking for the South of Spai
(EUPVCEC, 2013)
It is very unusual to have global irradiance data for a tilted surface and even more for a surface with a perfect sun tracking. The most common available data is the global horizontal irradiance, thus it is necessary to ...

Analysis of the distribution of measured and synthetic DNI databases and its effect on the expected production of a parabolic trough plant
(Elsevier, 2014)
The generation of a Typical Meteorological Year (TMY) is a common practice in solar energy projects. Therefore it is desirable that the TMY provides not only a good estimate of the solar resource in the long term, but also ...

Thermodynamic Limits of the Use of Solar Energy for Cold Production
(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 ...

Relations Between the Probabilities of Exceedance of Solar Radiation and Production of Concentrating Solar Thermal Systems
(American Institute of Physics Inc., 2020)
CSP feasibility analysis, bankability assessment and plant design are generally based in one-year meteorological series representative of “typical” o extreme conditions. There is a growing interest in accounting on the ...
