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 ...

Experimental evaluation of the solar radiation gains over photovoltaic cells due to the use of tio2 treated surfaces. Applications to photovoltaic systems with micro-inverters
(EUPVCEC, 2016)
In building integrated photovoltaic (PV) systems, the reflection of the solar radiation by the walls of the buildings may cause a non-uniform distribution of the incident radiation on the different PV modules. However, by ...

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, ...

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) ...

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 ...

Methodology to synthetically downscale DNI time series from 1-h to 1-min temporal resolution with geographic flexibility
(Elsevier, 2018-03)
In this paper, we present two methods for the synthetic generation of 1-min Direct Normal solar Irradiance (DNI) data from hourly means that can be applied globally without any local adaptation, which are based in the ...
