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

In this paper, solar photovoltaic system utilized in building sectors in China is assessed. For photovoltaic, the main reason causes low utilized is high capital cost. Another problem for photovoltaic is that solar cell has low efficiency when utilized in practical. In this study, some works have done to assess PV utilized in building sectors in China from the technology and economic aspects.

AbstractA new meta-heuristic Pathfinder Algorithm (PFA) is adopted in this paper for optimal allocation and simultaneous integration of a solar photovoltaic system among multi-laterals, called interline-photovoltaic (I-PV) system. At first, the performance of PFA is evaluated by solving the optimal allocation of distribution generation problem in IEEE 33- and 69-bus systems for loss minimization. The obtained results show that the performance of proposed PFA is superior to PSO, TLBO, CSA, and GOA and other approaches cited in literature. The comparison of different performance measures of 50 independent trail runs predominantly shows the effectiveness of PFA and its efficiency for global optima. Subsequently, PFA is implemented for determining the optimal I-PV configuration considering the resilience without compromising the various operational and radiality constraints. Different case studies are simulated and the impact of the I-PV system is analyzed in terms of voltage profile and voltage stability. The proposed optimal I-PV configuration resulted in loss reduction of 77.87% and 98.33% in IEEE 33- and 69-bus systems, respectively. Further, the reduced average voltage deviation index and increased voltage stability index result in an improved voltage profile and enhanced voltage stability margin in radial distribution systems and its suitability for practical applications.

AbstractLack of access to modern forms of energy hampers efforts to reduce poverty. The provision of electricity to off-grid communities is therefore a long-standing developmental goal. Yet, many off-grid electrification projects neglect mid- and long-term operation and maintenance costs. When this is the case, electricity services are unlikely to be affordable to the communities that are the project’s primary target. Here we show that, compared with diesel-powered electricity generation systems, solar photovoltaic systems are more affordable to no less than 36% of the unelectrified populations in East Asia, South Asia, and sub-Saharan Africa. We do so by developing geo-referenced estimates of affordability at a high level of resolution (1 km2). The analysis illustrates the differences in affordability that may be found at the subnational level, which underscores that electrification investments should be informed by subnational data.
