Solar module using dye-sensitized solar cells with a polymer electrolyte
(Elsevier Science BvAmsterdamHolanda, 2008)
Análise diferencial da potência máxima gerada por um sistema solar fotovoltaico
The Earth receives annually 1,5.1018 kWh of solar energy, which corresponds to 1000 times the world energy consumption in this period. This fact comes out that, besides being responsible for the maintenance of life on ...
Evaluation of integrated inverter topologies for low power PV systems
This work presents the stage integration in power electronics converters as a suitable solution for solar photovoltaic inverters. The rated voltages available in Photovoltaic (PV) modules have usually low values for ...
Estudo da atividade solar no passado em função da radiação cósmica
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2014-03-20)
The study about cosmic radiation arriving the Earth represents an important register of its variations, as the physical phenomena who cause these variations. In the solar system the variation is strongly modulated by the ...
Spectral response of polycrystalline silicon photovoltaic cells under real-use conditions
The standard test conditions for photovoltaic modules are not capable of reproducing the environmental variations to which the modules are subjected under real operating conditions. The objective of this experimental work ...
