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) ...

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 ...

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 ...
