“…[9]. To ensure the continuity of the power supply, it is appropriate to use a UPS whose charge is maintained by an independent energy source [10], which will guarantee the high reliability and trouble-free operation of the control system. All this positively affects the operating characteristics of water supply systems not only for urban conditions but also for small settlements.…”

“…The problem is that the I-V curve of the PV panels change together with the ambient conditions as temperature, angle of illumination, intensity and spectrum of radiation, and with the array degradation too, [2]. At the same time, the PV systems have a low investment return ratio compared to other conventional energy sources and it could be even worst because studies conclude that in certain cases there are significant amounts of unused energy, which further seriously reduces their efficiency, [3,4]. In such cases, it is important to increase the energy utilization if the PV investment is to be optimal.…”

The Photovoltaic (PV) systems are one of the key renewable energy sources that are becoming increasingly popular, but they still have many drawbacks compared to conventional energy sources. Their main disadvantages are that they require a lot of installation space and they have low investment return ration. Both could be overcome by local installation of the PV plants as close as possible to the end consumer, and the best case is the PV panels to be installed on the buildings, but this could lead to higher fire risk for the residents. Different PV panels degrade with different speeds and work under slightly different conditions. These problems require at least periodic PV panel diagnostics and the thermal infrared (IR) inspection seems to be the best solution. The prerequisites for correct IR diagnostics are presented. One of the requirements for detailed IR inspection is the thermal camera to capture each PV cell with at least 5 by 5 pixels in horizontal and vertical directions. A methodology for pixel size calculation and IR monitoring system design is developed and presented in this work.

The article examines the usage of hydrogen in gas transmission pipes as one of the measures to achieve the criteria of sustainable development and reduction of carbon emissions. Regarding choosing an appropriate kind, hydrogen sources have been analyzed. Due to the multifactorial nature of the task, such as raw material, price, efficiency, popularity, and the availability of many studies, a point system was developed to evaluate the alternatives with significant criteria. On its basis, it was established that the cheapest and gentlest natural method is the electrolysis of water. For this purpose, electrolysis methods have been evaluated, and efficiency depends on the energy source. Given the dependence of the price of energy on the country's energy mix, a point system is proposed based on the parameters: hydrogen's levelized cost LCOH and levelized cost of electricity (LCOE). The newest criterion is the citation rating which gives popularity and an opportunity for new research.
