“…The In many cases, an adjustment of photovoltaic cell inclination angle to the position of the sun may deliver additional profits [29,30]. The instantaneous values of the generated power of PV panels facing south and inclined at the optimal angle (PV1), which in the case of our location (Bialystok) is 38 • , are similar to the values obtained on identical panels placed on the tracker (PV3).…”

The effective operation of photovoltaic systems depends on many factors and parameters that must be continuously monitored. The factors listed in the article are frequently variable, which makes it very difficult to predict the amount of radiation that will reach photovoltaic panels and can be converted into electricity. Therefore, to optimize the operating point of a photovoltaic power plant, it is necessary to track the changes in these quantities. IoT systems may help in controlling and managing a power plant, storage, and energy flow to the power grid. The results recorded at the hybrid power plant of the Faculty of Electrical Engineering of the Bialystok University of Technology are useful for a comprehensive analysis of the operation of the plant and ways of its optimization. It is shown that implementation of a comprehensive maintenance system may deliver extensive important information regarding the PV plant installation.

“…The sky models developed, with luminance distributions determined for them in the zenith of the LVZ sky, reflect the state of the sky for individual degrees of cloudiness and diffusion of particles in the atmosphere. [18][19][20][21][22][23][24][25][26][27][28][29][30] According to the calculation procedure proposed by the CIE [17], geographical coordinates and time zone in the examined location are determined, and then the position of the Sun in the sky on a given day and at a specific time is determined. The declination angle , which determines the angular position of the blue equator relative to the ecliptic, is related to the next day in year n: 284 23, 45 sin 360 365…”

“…In the summer, the number of sunny days is about 50% to 70%, while, in winter, it is only 20% to 25%. As a result, in winter, the period of effective work of a PV power plant in Bialystok is very short, and the values of generated energy are rather low [6]. For the purpose of this work, the following installations were analyzed.…”

Sunlight is converted into electrical energy due to the photovoltaic effect in photovoltaic cells. Energy yield of photovoltaic systems depends on the solar array location, orientation, tilt, tracking and local weather conditions. In order to determine the amount of energy produced in a photovoltaic system, it is important to analyze the operation of the photovoltaic (PV) arrays in real operating conditions and take into account the impact of external factors such as irradiance, ambient temperature or the speed of blowing wind, which is the natural coolant of PV panels. The analysis was carried out based on mathematical models and actual measurement data, regarding the dependence of the average temperature of PV arrays on variable and difficult to predict ambient conditions. The analysis used standard (nominal operating cell temperature (NOCT)), King, Skoplaki, Faiman and Mattei thermal models and the standard model for flat-plate photovoltaic arrays. Photovoltaic installations PV1, PV2a and PV2b, being part of the hybrid power plant of the Bialystok University of Technology, Poland, were the objects of the research. In the case of a free-standing solar system, the Skoplaki model proved to be the best method for determining the average temperatures of the PV arrays. For building-integrated PV systems, a corrected value of the mounting coefficient in the Skoplaki model was proposed, and the original results were compared. The comparison of the accuracy measures of the average operating temperatures for three micro-power plants, differently mounted and located, is presented.
