Abstract: Disclosed are systems for exchanging batteries of an unmanned aerial vehicle (“UAV”). In some embodiments, a system may include a battery holding tube that is located on the UAV and that includes a first end with a first opening and a second end with a second opening and a battery loader configured to cause a battery to move into the battery holding tube through the first opening in a direction parallel to the center axis of the battery holding tube, wherein the center axis of the battery is parallel to the center axis of the battery holding tube, and cause the battery to move out of the battery holding tube through the second opening in a direction parallel to the center axis of the battery holding tube, wherein the center axis of the battery is parallel to the center axis of the battery holding tube.

Abstract: Disclosed are apparatuses and methods for an apparatus that has a flexible mounting substrate, one or more flexible photovoltaic modules attached to the flexible mounting substrate, one or more inverters attached to the flexible mounting substrate and electrically connected to the one or more flexible photovoltaic modules, a flexible electrical conduit electrically connected to the one or more inverters and to the one or more flexible photovoltaic modules, a plurality of mounting features, and a plurality of flexible connectors that extend between the flexible mounting substrate and one corresponding mounting feature, that is configured to be positioned above a structure and secured to the structure without penetrating roofing of the structure.
