The intensive development of photovoltaic (PV) micro-systems contributes to increased interest in energy efficiency and diagnosing the condition of such solutions. Optimizing system energy efficiency and servicing costs are particularly noteworthy among the numerous issues associated with this topic. This research paper addresses the easy and reliable diagnosis of PV system malfunctions. It discusses the original PV system energy efficiency simulation model with proprietary methods for determining total solar irradiance on the plane of cells installed at any inclination angle and azimuth, as well as PV cell temperature and efficiency as a function of solar irradiance. Based on this simulation model, the authors developed procedures for the remote diagnosis of PV micro-systems. Verification tests covered two independent PV systems over the period from April 2022 to May 2023. The obtained results confirm the high credibility level of both the adopted energy efficiency simulation model and the proposed method for diagnosing PV system functional status.

This paper is devoted to deliberations on transmittance measurement system properties and potential Pilot- Helicopter-Environment (P-H-E), in the security context of this system. Based on the operator's transmission of the Pilot-Helicopter (P-H) and the results of the stability studies, it is possible to obtain the answer about the scope of acceptable - for safety reasons - changes the operator's transmission coefficients. On the other hand, the potential recognition allows the inference about the properties of the P-H-E system in safety and reliability areas. The basis of this interference is the assumption concerning the system which is suitable for the safe implementation of tasks in certain conditions and if the P-H system has a required stability supply at the specified time.
