Atmospheric parameters, spectral indexes and their relation to CPV spectral performance

Description: Air Mass and atmosphere components (basically aerosol (AOD) and precipitable water (PW)) define the absorption of the sunlight that arrive to Earth. Radiative models such as SMARTS or MODTRAN use these parameters to generate an equivalent spectrum. However, complex and expensive instruments (as AERO...

Development of a full hybrid lighting-CPV prototype and savings in a real case operation

Description: A full Hybrid lighting-CPV prototype has been assembled. This new concept mixes a classical CPV module with the production of light for illumination without a double conversion (solar energy to electricity and electricity to light) allowing a higher efficiency to the whole system. The present protot...

Evaluation of misalignments within a concentrator photovoltaic module by the module optical analyzer: a case of study concerning temperature effects on the module performance

Description: Instituto de Energía Solar, Universidad Politécnica de Madrid (IES-UPM) has developed a method [referred to as the luminescence inverse (LI) method] and equipment [called module optical analyzer (MOA)] to fast measure the optical-angular properties of a CPV module without illumination system nor mod...

Characterizing CPV in a Lattice Mismarched World

Description: In this work, we discuss difficulties we have faced while characterizing non-LM-Ge based CPV modules at the Instituto de Energía Solar, including: 1. For MJ cells with a 1eV bottom, bottom sub-cells may be current matched to the other two cells at reference spectrum. 2.In the case of metamorphic sel...

Spectral classification of worldwide locations using SMR indexes

Description: Spectral variation of solar irradiance can be analyzed by the means of component cells, being useful for multi junction (MJ) and concentrator photovoltaics (CPV) characterization by the use of component cells derived spectral indexes, namely, spectral matching ratios (SMRs). When enough spectral dat...

Renewable energies Driven by Feed-on Tariffs. Photovoltaic vs Wind Energy Development in Spain

Description: Although others regulations regarding feed-in tariffs for photovoltaics (PV) existed in Spain previously, the one that meant a paradigm change was the introduction in 2007 of law R.D.661/2007 which established a feed-in tariff of 41,75 cents/kWh if the installed capacity was greater than 100KWp and ...

Modeling of a concentrating photovoltaic module

Description: The photovoltaic systems are characterized by low efficiency. To improve their efficiency we need to use concentrating photovoltaic systems. These CPV systems allowed the enhancing of the power which received by the cell. This high power can raise the potential of the electrons causing the heating o...

Relative misalignments estimation in on-tracker CPV modules through image processing

Description: This work uses a validated method to measure misalignments between optic units in CPV modules indoors (using a camera) to measure misalignments between modules outdoors. Since the measurement outdoors has different condition than indoors, acquired images require an enhancement, reached through image...
