In the realm of technological market penetration of solar photovoltaiclouvers (PVL) addressing environmental difficulties and the industrialrevolution, a new avenue of renewable energy is introduced. Moreover,solar energy exploitation through building façades was addressedthrough motorized solar photovoltaic louvers (MPVL). On the otherhand, proponents exalted the benefits of MPVL overlooking the typicalanalyses. In this communication, we attempted to perform a thoroughindustrial system evaluation of the MPVL. This communication presentsa methodology to validate the industrial claims about MPVL devices andtheir economic efficiency and the insight on how geographical locationinfluences their utilization and augment their potential benefits. This taskis carried out by evaluating the extent of solar energy that can be harvestedusing solar photovoltaic system (PVSYST) software and investigatingwhether existing product claims are associated with MPVL are feasible indifferent locations. The performance and operational losses (temperature,internal network, power electronics) were evaluated. To design and assessthe performance of different configurations based on the geographicalanalogy, simulation tools were successfully carried out based on differenttopographical locations. Based on these findings, various factors affect theemployment of MPVL such as geographical and weather conditions, solarirradiation, and installation efficiency. tt is assumed that we successfullyshed light and provided insights into the complexity associated withMPVL.

Objective: To establish a baseline about the solar photovoltaic energy systems installed in the department of Caldas, Colombia. Methodology: The solar photovoltaic installations were identified from secondary sources of information, followed by field visits to collect information on the characteristics of these systems. An evaluation instrument was designed consisting of 6 categories which was subsequently evaluated by expert peers. It was applied accompanied by interviews with owners of the identified systems. Results: 41 solar photovoltaic systems were identified and installed in 11 municipalities of Caldas. Data was collected from 28 installations with different characteristics. 50% of the solar photovoltaic systems are in the Central-South region of Caldas. 71% of the systems are mainly installed in the urban area; 64% correspond to small-scale isolated solar photovoltaic energy generation systems, with a maximum power of less than 600W. These installations have become a viable energy alternative for the region and are being used especially for lighting and the operation of household appliances in residences, hotels, restaurants, and educational institutions. Conclusions: Although regulations on solar energy installations had not been established, these systems have already been implemented in the department in a successful, but moderate, manner.

This study investigates 200 kWp roof-mounted solar photovoltaic system in a country where there is no legal, policy, and institutional framework to de-risk the solar energy market but present naturally conducive environment in the sun-drenched semi-arid country. The analysis of quantitative and qualitative data subject to interpretivist and positivist approaches paves the way to find out that the university, though created financial and environments values, has not addressed the risk associated with illiquid capital intensive investment and conventional financial metrics such as net present value, internal rate of return. Hence, it is recommended to manage the risk with four strategies including maintaining economic value added at 5% or more, leveraging the investment, and withdrawing a part of equity for reinvesting in diversified investment. The findings are significant for low carbon investors to identify opportunities and manage the risk in solar energy market. Energy engineers enable designing a system that meets the fundamentals of the business and environmental value.

Besides, water pumping is an important form of development in rural areas (family farmers) mainly because of the distance from distribution centers. Therefore, this paper aims to evaluate the energy conversion in a water pumping system applied to irrigation, powered by photovoltaic energy, and compare with a static system with a single axis manual three-steps sun tracking system. Two arrays of panels were installed in the field at 22° 42’30” S; 47°38’00” W; 546 m above sea level. One photovoltaic module was static and the other a manual sun tracking device. Each module was connected to an individual water pump to simulate an irrigation system. The results showed that the pumping system with manual tracking device had better performance in the energy conversion from photovoltaic to hydraulic, with increments of 177 MJ m-2, 50.87 more pumping hours, and 66,135 L. However, the conversion energy efficiency from solar energy to water pumping was 4.55% and 4.77% for tracking and static modules, respectively. The manual sun tracking systems used in the photovoltaic module feeding a pumping system to irrigation was a technical alternative to improve the performance of the photovoltaic system.   Keywords: renewable energy, water pumped, pumping time, global efficiency.     GRAH PONCIANO, V.

CONVERSÃO DA ENERGIA SOLAR FOTOVOLTAICA EM ENERGIA HIDRÁULICA APLICADA A SISTEMAS DE IRRIGAÇÃO UTILIZANDO UM RASTREADOR SOLAR MANUAL       2 RESUMO   O Brasil tem um potencial solar energético pouco explorado, apenas 1,2% da matriz energética é proveniente da energia fotovoltaica. Aliado a isso, o bombeamento de água é uma importante forma de desenvolvimento nas áreas rurais (pequenos agricultores) principalmente, devido a distância desses locais aos centros de distribuição de energia elétrica. Este trabalho tem por objetivo avaliar a conversão da energia em um sistema de bombeamento de água aplicada a irrigação, movido por energia fotovoltaica, comparando um sistema estático com um sistema rastreador solar manual com três ângulos de ajuste de eixo único. Dois conjuntos de módulos foram instalados no campo na localização de 22° 42’30” S; 47°38’00” W; 546 m acima do nível do mar. Um módulo permaneceu estático e o outro módulo com um sistema de rastreador solar manual. Cada módulo foi conectado a uma motobomba individual, simulando um sistema de irrigação. Os resultados mostraram que o sistema de bombeamento com o rastreador manual teve melhor desempenho na conversão da energia solar para hidráulica, com um incremento de 177 MJ m-2, 50,87 h a mais no tempo de bombeamento, e 66.135 L. Contudo, a eficiência da conversão da energia solar para o sistema de bombeamento foi de 4,55% e 4,77% para o módulo rastreador e estático, respectivamente. O sistema manual de rastreamento solar utilizado no módulo fotovoltaico, alimentando um sistema de bombeamento para irrigação, foi uma alternativa técnica capaz de melhorar a desempenho do sistema fotovoltaico.   Palavras-chave: energia renovável, água bombeada, tempo de bombeamento, eficiência global.

Abstract Developing nations have a critical need to increase electricity supply. Sudan has much unrealized potential for generating solar energy, particularly in the northern region. This research study focuses on designing a 1-GW solar power station in northern Sudan using the PVsyst7.0 software program. To determine the appropriate location for the solar-energy station, 14 criteria were evaluated. This process is generic and suitable for use in any other country. The method for conducting cash-flow estimates and return on investment is illustrated in the economic evaluation. The city of Dongola, the capital of the northern state, was selected because of its high annual irradiance on a horizontal surface at ~2333.2 kWh/m2. The simulation results show that the annual optimum tilt angle of inclination for photovoltaic (PV) modules is 30°, the energy production is 1 979 259 MWh/yr and the average annual performance rate is 0.810. In addition, the electric power consumption per capita in Sudan is 269 kWh/yr, so the proposed solar power plant with 1 979 259 MWh/yr can provide energy to 7.4 million people per year annually and reduce carbon emissions by ~18 million tons of carbon dioxide per year. Economic calculations show that the levelized cost of electricity (LCOE) is $0.06/kWh, the discounted payback period is ~11 years and the net present value is $635 291 000. As a result, the proposed grid-connected PV solar plant is considered economically, technically and environmentally feasible in Sudan.

AbstractThe use of LED lights in smart street lighting to save energy is efficient and very common in many developed cities. However, such a system results in higher initial costs, which may discourage smaller towns and villages from its purchasing. This paper therefore deals with the design and development of a smart street lighting control system for smaller cities and villages. Such a system is required to be economical from the perspective of development and production. Considering other requirements such as platform independence, high availability and broad support, we proposed to build a system as a web application using a custom light control service component. The result is a web application that consists of a user interface served by a web server and an application server used to communicate with light control service. In addition, the system is designed as a geographical information system to be easy to use for managing street lights in groups or individually, while displaying them on the map. The system allows automatic sensor-based light intensity modulation by default with the possibility of manual adjustment or override of the illumination. It also includes a device error notification system with a tool to navigate faulty devices. The presented system is a low-cost solution for intelligent street lighting control designed for smaller cities or villages. They can apply the designed architecture of the system and the specific technologies suitable because of their low-cost implementation.
