Resumo: | The main objective of this work was to fabricate and to characterize static concentrator photovoltaic modules (MEC-P) with bifacial solar cells and diffuse reflector. PV concentrator modules and PV standard modules with the same solar cell area were installed in a stand-alone PV system at 1.5 years and these were electrically characterized after the solar radiation exposure. The PV systems were monitored, measuring the irradiance (total and ultraviolet) at the same plane of PV modules, the voltage of battery, the electric current to the load and the electrical voltage and current of PV modules. Two PV concentrators were manufactured with dimensions of 775 mm x 690 mm x 70 mm (length x width x thickness) and with 36 bifacial solar cells with 80 mm x 80 mm, soldered in series. With cells whose average efficiency was (13.8 ? 0.2) % and (13.2 ? 0.2) % for front and rear mode illumination, respectively, one module with efficiency of 7.8 % was fabricated. By using solar cells of (13.7 ? 0.2) % / (13.1 ? 0.3) % for front / rear illumination mode, the efficiency achieved by the PV module was 7.6 %. It was estimated that the temperature of the solar cells in PV module concentrators was about 5 ?C to 9 ?C higher than that of PV standard modules with the same type of glass and similar lamination materials. The PV concentrators were subjected to total radiation of around 1.9 MWh/m? (6.84 x 109 J/m?) for 1.5 years and presented no degradation of their visual appearance as well as its electrical characteristics. The PV stand-alone system installed with MEC-P modules showed a monthly average efficiency of (6.5 ? 1.0) % in the period in which the load was held constant. The efficiency was 1.0 % lower than that obtained with the modules MEC-P was due to the higher operating temperature, the higher reflectance of solar radiation when the PV modules are installed on the tilted plane and has variation of the angle of incidence during the day, the resistive losses in the system and because in the calculation of system efficiency it was considered the electrical energy produced and stored. |

M?dulos fotovoltaicos concentradores e m?dulos convencionais com a mesma ?rea de c?lulas foram instalados em sistemas fotovoltaicos isolados por aproximadamente 1,5 anos e os mesmos foram caracterizados eletricamente ap?s o per?odo de exposi??o ? radia??o solar. Os sistemas fotovoltaicos foram monitorados, medindose a irradi?ncia (total e ultravioleta) no plano dos m?dulos, a tens?o do banco de baterias, a corrente el?trica na carga, a tens?o e a corrente el?tricas dos m?dulos fotovoltaicos. Dois m?dulos fotovoltaicos concentradores foram constru?dos com as dimens?es de 775 mm x 690 mm x 70 mm (comprimento x largura x espessura) e com 36 c?lulas solares bifaciais de 80 mm x 80 mm, soldadas em s?rie. Com c?lulas cuja efici?ncia m?dia foi (13,8 ? 0,2) % e (13,2 ? 0,2) % para ilumina??o pela face frontal e posterior, respectivamente, fabricou-se um m?dulo com efici?ncia igual a 7,8 %. Com c?lulas de (13,7 ? 0,2) % / (13,1 ? 0,3) % para ilumina??o frontal/posterior, a efici?ncia alcan?ada pelo m?dulo foi de 7,6 %. Estimou-se que a temperatura das c?lulas solares nos m?dulos concentradores foi da ordem de 5 ?C a 9 ?C maior que a de c?lulas solares em m?dulos convencionais com o mesmo tipo de vidro e materiais de encapsulamento similares. Os m?dulos concentradores foram submetidos ? radia??o total de aproximadamente 1,9 MWh/m2 (6,84 x 109 J/m?) durante 1,5 anos e n?o apresentaram nenhuma degrada??o de seu aspecto visual bem como de suas caracter?sticas el?tricas. O sistema fotovoltaico isolado instalado com m?dulos MEC-P apresentou uma efici?ncia m?dia mensal de (6,5 ? 1,0) % no per?odo em que a carga foi mantida constante. A efici?ncia de 1 % abaixo da obtida com os m?dulos MEC-P foi devida ? maior temperatura de opera??o, a maior reflet?ncia da radia??o solar quando os m?dulos s?o instalados no plano inclinado e h? varia??o do ?ngulo de incid?ncia durante o dia, ?s perdas resistivas no sistema e porque no c?lculo da efici?ncia do sistema foi considerada a energia el?trica produzida e armazenada.Made available in DSpace on 2015-04-14T13:58:55Z (GMT).
