摘要： Due to their exposure to extreme environments, it is expected that parts or all of a solar power system will experience degradation in performance. The degradation may be due to temporary environmental factors, such as cloud cover; damage or localized soiling; a general dirty condition; or ageing of the components. A method is disclosed wherein a remote system may detect degraded performance and determine the cause, thereby enabling a decision as to the appropriate corrective action to be taken, if any.

摘要： A base unit is mechanically connected to the structure of a first electronic device. The base unit is round and includes conductive threads around the inside surface of an outer ring. The base unit may also include a center threaded post with conductive threads. The first electronic device is electrically connected to the base unit. A replaceable unit is sized such that it may screw into the base unit, the replaceable unit including matching threads which engage with the threads of the base unit. The threads of the replaceable unit are also electrically conductive, and are electrically connected to a second electronic device which is encapsulated within the replaceable unit. When the two pieces are screwed together the two electronic devices are thereby electrically connected. The first electronic device may be a solar panel. Another version of the invention does not include electrical connections.
