Abstract

This paper analyzes the potential of solar energy and the efficiency of a solar system for real measurements. During the analysis, one-year radiation measurements for the city of Pristina were used. Analyzes show a high potential for exploitation. What affects the increase of efficiency of such systems is the possibility of use throughout the year.  For each respective month is shown the potential of thermal energy that can be achieved and efficiency. The paper highlights the role of solar energy in maximizing the penetration of renewable sources. The analysis shows that in August the coverage of the needs for hot sanitary water from the proposed solar system is 99% and minimally in January by 16%. Taking into account the seasonal changes that apply to the country, I consider that a possible combination of central heating systems with those of sanitary water - solar system would be an adequate solution.

Abstract

The modeling of a photovoltaic (PV) system used for the needs of the industrial sector is presented in this paper. Its analysis was done analytically using real one-year measurements during the system monitoring period and software-wise using premium PV*SOL software. System generated energy, maximum power point (MPP) voltage, final yield and average generated power are included in the analysis. The highest summer energy produced for real conditions is in July with 2811.86 kWh, the highest MPP voltage also presented in July with a value of 400 V. The final yield with a value of 103.07 kWh/kWp and the highest average power 16.6 kW as well. during the month of July. Where it can be seen that due to the Mediterranean atmospheric conditions in the place of application of the PV system, during the summer months the parameters are higher than during the winter months.
