Analytical Estimation of the Energy Provided by the Battery-Based Photovoltaic Power Supply

Nowadays, surveillance and protection systems are standard equipment at many airports. However, their use can be quite restrictive in the case of their relatively short-term use in an area that does not normally extend to their perimeter of protection. The limiting factor in such situations is mainly their low mobility and dependence on external galvanic lines, especially if the individual sensors require mutually different power requirements. In consequence, this article is devoted to the analytical estimation of the energy provided by the photovoltaic power supply for a mobile monitoring unit, intended to monitor a surrounding area and inform about a possible unauthorized intrusion into perimeter protection. The essence of the analysis was to estimate the time of the one discharging cycle during which the designed battery-based photovoltaic system power supply can continuously provide sufficient energy to keep the mobile monitoring unit in its full operational mode.
