This paper presents a methodology to estimate solar irradiance using an empiric-stochastic approach, which is based on the computation of normalization parameters from the solar irradiance data. For this study, the solar irradiance data were collected in a weather station during a year. Posttreatment included a trimmed moving average to smooth the data, the performance of a fitting procedure using a simple model to recover normalization parameters, and the estimation of a probability density, which evolves along the daytime, by means of a kernel density estimation method. The normalization parameters correspond to characteristic physical variables that allow us to decouple the short- and long-term behaviors of solar irradiance and to describe their average trends with simple equations. The normalization parameters and the probability densities allowed us to build an empiric-stochastic methodology that generates an estimate of the solar irradiance. Finally, in order to validate our method, we had run simulations of solar irradiance and afterward computed the theoretical generation of solar power, which in turn had been compared with the experimental data retrieved from a commercial photovoltaic system. Since the simulation results show a good agreement with the experimental data, this simple methodology can generate the synthetic data of solar power production and may help to design and test a photovoltaic system before installation.

The period of industrialization and modernization has increased energy demands around the world. As with other countries, the Taiwanese government is trying to increase the proportion of renewable energy, especially solar energy resources. Thus, there are many solar power plants built in Taiwan. One of the most important components of a solar power plant is the solar panel. The solar panel supplier selection process is a complex and multi-faceted decision that can reduce the cost of purchasing equipment and supply this equipment on time. In this research, we propose fuzzy MCDM approach that includes fuzzy analytical hierarchy process model (FAHP) and data envelopment analysis (DEA) for evaluation and selection of solar panel supplier for a photovoltaic system design in Taiwan. The main objective of this work is to design a fuzzy MCDM approach for solar panel supplier selection based on qualitative and quantitative factors. In the first step of this research, FAHP is applied to define the priority of suppliers. The AHP combined with fuzzy logic (FAHP) can be used to rank suppliers; however, the disadvantages of the FAHP model is that input data, expressed in linguistic terms, depends on experience of experts and the number of suppliers is practically limited, because of the number of pairwise comparison matrices. Thus, we applied several DEA models for ranking potential suppliers in the final stages. As the result, decision making unit 1 (DMU 1) is the optimal solar panel supplier for photovoltaic system design in Taiwan. The contribution of this research is a new fuzzy MCDM for supplier selection under fuzzy environment conditions. This paper also lies in the evolution of a new approach that is flexible and practical to the decision maker. It provides a useful guideline for solar panel supplier selection in many countries as well as a guideline for supplier selection in other industries.

Abstract—This paper presents the design of a 2kW portable photovoltaic (PV) stand-alone facility (PV generator) that converts directly solar irradiance into electricity for immediate use or storage. The project aims to build a stand-alone solar power source for use in rural villages, mountainous and remote areas that are distant from the national grid. It can also be very useful for powering camping tents, fishing boats, small farms, and greenhouses. Equally, it could be used for disaster stricken areas and during power outages. However, the proposed generator will be more suited for camping trips that Emiratis take almost in weekly basis. The paper will focus on presenting the main features of the designed prototype. It will also investigate the performance of the proposed stand-alone PV generator. Parameters investigated include geographic location, climate condition, solar irradiance, load consumption, ambient temperature, array voltage, battery voltage, and energy output from the array. The work presented is based entirely on the work carried out by final year electrical engineering students, during their capstone design project. The project work, presented, is a manifestation of the students learning during earlier semesters. It puts into practice the application of solar energy technology, that the student learned in his course on renewable energy systems.  Index Terms—Solar energy,transportable solar system,stand-alone system,PV,photovoltaic system.

During the operation of photovoltaic installations, the inconstancy of the energy characteristics of the flow of incident solar radiation adversely affects the generation of electrical energy. Consumers are highly dependent on climatic factors and solar insolation. For more efficient operation of generating solar installations, it is necessary to conduct detailed studies of the characteristics of the auxiliary and control equipment of the photovoltaic system. When using mathematical programs to simulate the operating modes of solar power generating systems, it is possible to significantly improve the operating parameters of control units and auxiliary systems and increase the generation of electrical energy. The paper presents an improved electrical diagram of a photovoltaic generating system, its control elements, and the efficiency of energy generation is increased. It also describes a method for modeling the operating modes of photovoltaic (PV) modules, implemented in the Matlab/Simulink program. In the work, it was necessary to define a circuit simulation model for the solar array to ensure interaction with the power converter. The characteristics of the solar cells, which are influenced by irradiation and temperature, are modeled by a circuit model. A simplified equivalent circuit for a diode equivalent PV system is used as a model. The simulation results are compared with different types of PV module data. As a result of the work, it was shown that the created simulation blocks in the Matlab/Simulin system well simulate the operation of solar panels, while they are compatible with different types of photovoltaic modules and are convenient in providing various operating modes. In the study of real operating modes of the proposed generating system, the possibility of increasing the generation of electrical energy was shown. When using the proposed circuit solutions for the operation of solar installations, it is possible to significantly increase their efficiency, extend the trouble-free operation, and increase the service life of the equipment. The conducted research contributes to a better use of blocks of photovoltaic systems used to provide electrical energy to industrial, municipal and individual consumers. The circuit solutions proposed in the work are possible for use both at large solar power plants operating in parallel with the general energy system, and at small photovoltaic installations used to provide individual consumers.

Abstract Background: The government is optimistic that Indonesia is able to be energy independent because Indonesia has a variety of energy sources that can be utilized for the benefit of the nation and state, both fossil and non-fossil energy sources, including solar energy through solar power system. The solar power system or photovoltaic system is an eco-friendly option usually applied to meet the need for energy due to its lower carbon footprint when compared to fossil-fueled power plants. This research was, therefore, used to conduct a techno-economic and regulatory impact analysis on a rooftop photovoltaic system installed in a mosque in Purworejo, Indonesia under a net metering mechanism. Result: The installation was aimed at reducing entire carbon emission from the annual energy usage which is an equivalent of 4 tons of carbon dioxide. The research shows that the economic feasibility of the photovoltaic systems, measured by the Net Present Value (NPV) of the electricity bill saving are negative values for all the configurations based on the type and number of panels. This low financial attractiveness was observed to be due to several unsupportive regulations such as subsidized electricity tariff, minimum grid electricity usage limit, and less-rewarding net metering scheme. The research also suggests that the abolishment of the minimum usage limit was discovered to have incurred the greatest increase of NPV to the photovoltaic system designed to entirely supply the load demand while the implementation of a higher electricity tariff caused the highest increase of NPV for the photovoltaic systems with partial supply scenario. Conclusion: Finally, it is financially unfeasible to install a photovoltaic system on the mosque rooftop at the current electricity tariff, costs of components, and regulations implemented concerning the adoption of the system. As a constraint, the power regulation in Indonesia should be reviewed significantly to support any buildings of worship to develop their opportunities for managing energy systems independently. The potential implication is that they would be able to contribute their social economic role in supporting their really crucial community daily life energy. This approach is in line with the government policy and strengthening the sustainable development goals.


Traditional fossil energy sources are increasingly exhausted, leading to the need for mankind to exploit alternative energy sources; and solar energy can be viewed as infinite. Solar photovoltaic and its applications are increasingly widely studied. However, due to its nonlinearity and unstable nature, high technology is required to achieve good conversion efficiency. One of the techniques to optimize solar cell efficiency is to use the Maximum Power Point Tracking algorithm (MPPT) and P&O is a relatively easy algorithm to implement. This article will present some problems about photovoltaic cells, power converters in solar power systems and using PSIM software to simulate an independent solar system with several harvesting solutions for solar power and compare the efficiency of them.


This project proposed a solar power generation system is used for the MPPT (maximum power point tracker) controller in a nine-level inverter. The selection of the capacitor circuit is configured using nine-level inverter and a cascade-connected to the full-bridge power converter. The nine-level inverter contains seven powers. Electronic switches simplify the configuration of the circuit system. A single electronic power switch is switched to the high frequency at any time to generate a nine-level output voltage. The output of the photovoltaic solar panel system will be fed into an MPPT algorithm to obtain a maximum amount of energy from a photovoltaic system, and this technique is used for the generation of residential renewable energy. The output voltage of a photovoltaic solar system is completed by the use of the DC-DC power converter with independent voltage sources for an inverter and reduces the harmonics generated. The nine-level inverter reduced with switches in power generation.
