Energy consumption is a major factor in relation to an organization's costs and expenses, determining the need to apply methods that can minimize or reduce these expenses as much as possible. Having these factors in context, the present work aims to present the technical feasibility of implementing a project that uses solar energy through the on-grid solar system to supply the energy demand of a company. The methodology used was the descriptive, in which several data were collected and documentations were analyzed that supported and justified the elaboration of a photovoltaic project and development of the budget and analysis of the costs of a solar energy system. Through the results obtained, it was possible to arrive at a solar project that would be able to establish the necessary power for the company for a cost of R $ 20,916.96 and a payback of 5 years and 5 months. Thus, it is possible to conclude that the photovoltaic system is viable in its use and application, not only because of the advantages associated with the environment, but taking into account its self-sustainability over time and with a useful life of up to 25 years.

The multiport DC-DC power converter is a prominent area of research in power electronics due to its highly dense design, reduced device count, and high energy efficiency. In this paper, a nonisolated single magnetic element-based high step-up three-port converter for an energy storage system is presented. The proposed converter has two input ports and one output port. The coupled inductor with switched capacitor is used to achieve high voltage gain. The key features of the proposed converter are high conversion gain, low voltage stress, zero voltage switching (ZVS), and zero current switching (ZCS). The detailed theoretical analysis and operation of the converter are elaborated. The energy efficiency of the proposed converter is calculated and compared with the other counterparts. Ansys Maxwell is used for the coupled inductor finite element modeling. To verify the applicability and functionality of proposed converter, a 100  W converter with two inputs ( 48  V and 96  V ) and one output 360  V at 100  kHz is tested in the laboratory.

This thesis presents the methodology developed to identify the most cost-effective specifications that could be applied to the currently practiced new housing constructions in Canada to achieve improved energy efficiency standards, while maintaining an adequate level of thermal comfort. The results showed that, based on the life cycle cost analysis of 30 years, the optimal solutions (or upgrades) comprised of improvement in the thermal resistance of the building envelope, and installation of the most efficient heating, ventilating, and air-conditioning systems, resulting in up to 31% reductions in the estimated annual energy consumption and the greenhouse gas emissions, while achieving an EnerGuide Rating of 8, thereby meeting the new requirements of the upcoming 2012 Ontario Building Code. With the installation of a residential photovoltaic system, the estimated profit of up to $89,035 could be achieved through Ontario's micro Feed-in-Tariff (FIT) program, allowing a homeowner to pay for the implementation of additional upgrade(s).

The challenge of photovoltaic integration as the basis of an energy generation system has been achieved and carried out by the University Autónoma de Cali, Colombia, using an avant-garde energy technology model. This innovative sustainable campus not only fulfills its purpose as an advanced model of a renewable energy integration system, it also aims at environmental research, e-mobility, and energy efficiency. This paper describes how the university implements the technological innovation of integrating the photovoltaic system installation in a university campus, showing its relevant contribution to the electricity generation in the campus buildings by analyzing the different electrical parameters together with the system performance indicators. The implementation of technological solutions has allowed the generation of a quantity of renewable energy within the campus, supplying a sustainable energy response based on energy efficiency and carbon emissions savings. This innovation has been applied following the international standards for the evaluation of the energy performance of photovoltaic systems (IEC 61724), reaching very optimal values for this type of renewable solution. In this paper, the dynamic monitoring of several parameters has been carried out in order to analyze the energy performance, and an energy simulation has been used to achieve optimal solutions and to obtain the perfect modeling of the system. This study shows how to evaluate the performance of an integration of a photovoltaic system in a smart university campus, according to international standards. It achieves complete viability due to its economic savings, energy efficiency and reduction of carbon emission.

Today, excessive consumption of fossil fuels in architecture, especially air terminals and with the increase in the number of terminals along with population growth, the energy shortage crisis in the not-so-distant future in this high-use structure predicted. Therefore, the present study aims was designing an air terminal using photovoltaic panels with an energy efficiency optimization approach. The most important energy efficiency of the sun is its direct conversion to electricity. One of the systems for direct conversion of energy from radiation to electrical energy is the photovoltaic system. Advantages of using photovoltaic panels have led to the growing use of these plates at various scales. In addition, the use of photovoltaic panels as structural elements in architecture has created innovations in the building industry and has given a new meaning to the architecture. The use of photovoltaics in terminals is a smart method to bring contemporary architecture to a new concept in green architecture. Finally, we can say that photovoltaic module has a double function in the terminal; that is, photovoltaic module also replaces conventional building materials and they produce electricity. By replacing photovoltaics, cost of materials is deducted from the total cost of the building and the cost of the photovoltaic acquisition is partially offset. Such as the integration of photovoltaics with the roof which is the best way to get the maximum efficiency of the system in which the sun is perpendicular to it.
