A series of public policies are being adopted worldwide to seek greater participation of renewable energy sources in the energy matrix. Brazil is a country that has a predominantly renewable energy source, with hydroelectric energy being responsible for the largest portion, but with enormous potential to be exploited for solar energy. The objective of this study was to carry out an analysis of the economic viability of a photovoltaic matrix in the distributed microgeneration model from the residential consumer perspective. Through the Monte Carlo simulation, 10.000 iterations were performed and the NPV was calculated in each of them, then counted to recover the corresponding output probability distribution and verified the NPV probability to be greater than zero. The developed method has proved to be a reliable tool to support decision making and can be applied to several scenarios. The scenario adopted for the design of the photovoltaic system presented a 95.2% probability of returning with an NPV above zero and this makes it economically feasible. The main contribution of this paper is the replicability of the methodology used for other economic analysis studies.

Solar energy can be converted directly into electricity using photovoltaic cell technology. It is considered as the technology of the future because it uses the Sun, a clean and inexhaustible source. Thus, this study aimed to evaluate the economic viability in energy generation of a photovoltaic system in a rural community in the district of Rio do Salto. The rural community is in the municipality of Cascavel, western region of the state of Paraná, geographical coordinates latitude 25°8'31"S, longitude 53°19'40"W and altitude 781 m. Rio do Salto has regulations of 19 blocks with 241 properties. The evaluated properties belonged to block 11. The project was feasible when the payback period of the investment occurred within the expected photovoltaic system life cycle and if the internal rate of return (IRR) was higher than the minimum attractiveness expected for the project. To ensure the viability of this power generation system, the average consumption over the 12-month period should be higher than the rate of availability of the concessionaire that the owner should pay. This value varied according to the connection type (single-phase: 30 kWh, two-phase: 50 kWh and three-phase: 100 kWh). Property 9 was the only one that did not show conditions for photovoltaic system for not reaching the minimum connection tariff of the concessionaire.

[email protected]   RESUMO: Embora careçam de estudos de viabilidade, soluções baseadas em energia fotovoltaica têm se tornado muito atrativas para irrigantes, principalmente devido às constantes elevações nos custos de eletricidade. Com isso, objetivou-se realizar um estudo sobre a viabilidade econômica do uso da energia fotovoltaica para irrigação nas regiões do Vale do Jequitinhonha e Norte de Minas Gerais. Para a realização do trabalho utilizou-se a base de dados disponibilizada pelo Atlas Brasileira de Energia Solar e como índice de viabilidade econômica da energia fotovoltaica, o custo nivelado de energia (LCOE). Os valores de LCOE foram comparados com valores ponderados da tarifa de energia elétrica, em R$ kWh do Grupo Tarifário B2 Rural em diferentes cenários com jornadas de trabalho (noturna e diurna). Observou-se que quanto maior a radiação solar disponível e quanto maior a potência do sistema fotovoltaico, maior a tendência de viabilidade do investimento, em virtude da redução do LCOE. O uso de energia fotovoltaica é viável, com exceção das menores potências no Vale do Jequitinhonha e microrregiões limítrofes com o Norte de Minas, quando comparada ao uso exclusivo diurno da irrigação. O uso majoritário da tarifa com desconto noturno é uma alternativa à energia fotovoltaica quando se trata de viabilidade econômica.   Palavras - chave: irradiação solar, custo nivelado de energia, tarifa de energia elétrica.   ECONOMIC FEASIBILITY OF PHOTOVOLTAIC ENERGY FOR FARMERS IN NORTHERN MINAS GERAIS STATE AND JEQUITINHONHA VALLEY   ABSTRACT: Although there is a lack of feasibility studies, solutions based on photovoltaic energy have become attractive for farmers due to the constant increases in electricity costs. Thus, this paper aimed to evaluate economic viability of photovoltaic energy for irrigation in the regions of Jequitinhonha Valley and the Northern Minas Gerais State. The database uses in this study came form the Brazilian Atlas of Solar Energy was used. The levelized cost of energy (LCOE) was used as an economic viability index for photovoltaic energy.  The LCOE values were compared with the energy tariff weighted values, in R$ kWh, of the B2 Rural Tariff Group in different nights and day-working hours scenarios. It was observed that the greater the generation potential and the power of the photovoltaic system, the greater the trend of investment viability due to the LCOE reduction. The use of photovoltaic energy is feasible, except to lower powers in the Jequitinhonha Valley and Northern Minas Gerais State neighboring microregions, when compared to daytime irrigation. The mainly use of the nightly discounted energy tariff is an alternative to photovoltaic energy when it comes to economic viability.   Keywords: Solar radiation, LCOE, Energy tariff

Do So

The objective of this study was to verify the economic viability of generating systems of wind energy and solar photovoltaic in the water pumping for irrigation in fruit trees in the country properties. To do so, there is an applied research at two stations in Santa Maria, the first being located in the community of Canabarro and the second in Polytechnic College of the UFSM. The data were collected in the period of September of 2007 and September of 2008. The results demonstrated the viability to the wind equipment and solar photovoltaic for use in the complementary irrigation for crops of guava, fig and vine. With the photovoltaic system, the pumped volume was of approximately 5000 m3 / h with wind system and the pumped volume was 6 m3/ha. The wind sets showed low efficiency when compared to the photovoltaic systems, which are more efficient
