Abstract: The invention contributes to combat climate change by enabling the operation of a photovoltaic (PV) plant at high performance by providing based on the typically available metering a more or less topology agnostic automated set-up. Additional information can also be used such as sun positions and/or being designed for nominal powers. The invention relates to a method for determining performance deviation of a PV configuration, only taking electrical measurements into account thus excluding irradiance data. In addition, a method is provided for detecting underperformance within a PV plant with high accuracy. The invention also relates to a method for determining long-term degradation of a PV installation.

Abstract: According to one embodiment of the present disclosure, a head-mounted display device is provided, including a display, one or more input devices, and a processor. The processor may be configured to display a first 360-degree video on the display in a three-dimensional playback environment. The processor may be further configured to display a post-roll on the display when the first 360-degree video ends, wherein the post-roll is displayed in the three-dimensional playback environment and includes one or more interactable icons. The processor may be further configured to detect a selection of an interactable icon of the one or more interactable icons via the one or more input devices. The processor may be further configured to, in response to detecting the selection, perform a video environment navigation action.
