Devising a calculation method for determining the impact of design features of solar panels on performance

An actual scientific and practical task related to the sustainable development of the country’s energy sector is to forecast parameters and predict the conditions of operation of solar cells and solar batteries in regular and non-regular situations. It is emphasized that this makes it possible to provide solar energy with high efficiency indicators, in particular, the indicator of profitability on invested capital in the construction of solar panels. The main specific research method is regression analysis – to build a forecast model of the total amount of generated energy of solar panels in ground installations under variable conditions of operation. An analysis of the distribution of the output data of the model by the number of solar battery modules was carried out using the example of terrestrial solar installations. To obtain empirical data, 31 objects in the Dnipropetrovsk and Zaporizhia oblasts, which have functioning solar batteries with different numbers of modules, were selected. This makes it possible to calculate the weighted average amount of generated energy during operation under variable conditions. 10 intervals of frequency values were separated with the largest range of values within the interval of 10,000–20,000 pieces of solar modules. A model of the dependence of the total amount of generated energy on the number of solar battery modules and the weighted average amount of generated energy was built based on regression analysis. It was determined that the influencing factor of the model «number of solar modules» has a positive influence on the resulting factor (productivity of solar panels), while the influencing factor «weighted average amount of generated energy» has a negative influence. However, the «number of solar modules» influence factor is more significant. The obtained results give grounds for asserting the possibility of their implementation in the energy sector

DETERMINATION OF THE INFLUENCE OF THE SOLAR CELLS DESIGN ON THEIR FUNCTIONING EFFICIENCY

An essential scientific and practical problem of sustainable development of the country’s energy sector is predicting the parameters and foreseeing the conditions of functioning of solar cells and solar elements in normal and emergency situations. It is emphasized that this allows to provide solar energy with high efficiency indicators, including return on invested capital in the solar panels construction. The main specific research method used is regression analysis aimed at building a model for predicting the total amount of generated energy from solar cells in ground-based installations under variable conditions. The distribution of the model output data by the number of solar cell modules is analyzed on the example of ground-mounted solar installations. To obtain empirical data, we selected 31 facilities in the Dnipro and Zaporizhzhia regions that use solar cells with different numbers of modules. This allows to calculate the weighted average amount of energy generated during operation in variable conditions. We distinguished 10 intervals of frequency values, with the largest range of values being in the range of 10000-20000 solar cell modules. The regression coefficients were checked by two criteria. According to the criterion of “t-statistics value”: the coefficients are significant at a significance level of 0.05. The criterion of asymptotic significance determines the rejection of the null hypothesis in a statistical test. The random value is 170.3694, which is significantly higher than the critical value of the F-statistic of 3.33. A model of the dependence of the total amount of generated energy on the number of solar modules and the weighted average amount of generated energy was built on the basis of regression analysis. It is determined that the model influence factor “number of solar modules” has a positive effect on the resultant factor (solar cell productivity). Whereas the influence factor is “weighted average amount of generated energy”. However, the influence factor “number of solar modules” is more significant. The obtained results allow us to assert the possibility of their implementation in the energy sector.

The Comparison of Solar-Powered Hydrogen Closed-Cycle System Capacities for Selected Locations

The exhaustion of fossil fuels causes decarbonized industries to be powered by renewable energy sources and, owing to their intermittent nature, it is important to devise an efficient energy storage method. To make them more sustainable, a storage system is required. Modern electricity storage systems are based on different types of chemical batteries, electromechanical devices, and hydrogen power plants. However, the parameters of power plant components vary from one geographical location to another. The idea of the present research is to compare the composition of a solar-powered hydrogen processing closed-cycle power plant among the selected geographical locations (Russia, India, and Australia), assuming the same power consumption conditions, but different insolation conditions, and thus the hydrogen equipment capacity accordingly. The number of solar modules in an array is different, thus the required hydrogen tank capacity is also different. The comparison of equipment requires building an uninterrupted power supply for the selected geographical locations, which shows that the capacity of the equipment components would be significantly different. These numbers may serve as the base for further economic calculations of energy cost.

A simple model for the energy supply of a stand-alone house using a hybrid wind–solar power system

A research project for secondary school students involving both physical measurements and modelling is presented. The problem to be solved is whether and how a typical house can be supplied with energy off-grid, based entirely on renewable energy sources, more specifically, on solar and wind energy, while using relatively simple devices, namely, photovoltaic modules, wind turbines and accumulators. To this end our students carried out a long term measurement series in order to assess the typical energy consumption of houses. Further, the number of solar modules and wind turbines, and the necessary accumulator capacity, was estimated.
