automatically for each of the solar radiation components every hour from sunrise
to sunset. In contrast, the majority of spectral information is recorded
only in specific campaigns where the volume of information is much smaller,
and cannot be filtered or visually checked. In this case, the need for filtering
is must be met automatically, and there are no tools developed for it.
Validation of global, diffuse and direct normal spectral solar radiation models
There are several spectral models available, but they were developed with
certain starting hypotheses. In the context of this project, these models were
validated in the atmospheric conditions recorded during the measurement
campaign.
Characterization of local atmospheric parameters from spectral distribution of
solar radiation in the desert of southeastern Spain.
Spectral data are an important source of information for characterizing local
atmospheric parameters. These parameters, which in turn determine the
solar radiation that reaches the Earth’s surface at a specific site, are insufficiently
developed in desert atmospheres like the one at the PSA.
Characterization and analysis of the influence of the spectral distribution of
solar radiation on different technologies.
Another of the outstanding goals of this project concentrates on the influence
of the distribution on solar energy applications. To date, the influence
best characterized is the effect of the spectral distribution on photovoltaic
generation. In the context of this project, photovoltaic panels with different
technologies were installed along with solar spectral radiation measurement
devices in order to quantify the relationship in each case.
This project has been invited to present an extension, enlarging the study
of the effect of spectral distribution on other technologies using solar radiation.
