Abstract: A replaceable solar bulb assembly generates electrical energy that includes a photo voltaic cell for converting solar energy into electrical energy. A housing includes at least one reflector for focusing the solar energy on the photo voltaic cell. A connector removably and mechanically connects the housing to a solar receiver array and electrically connects the photo voltaic cell to the solar receiver array.

Abstract: A portable solar energy generation system has a solar energy receiver having a plurality of solar cells for converting solar energy into a DC voltage. A solar tracking mechanism enables the solar energy receiver to track a position of the sun with respect to the solar cells and to position the solar cells responsive thereto. Power circuitry generates at least one output voltage to power an electronic device responsive to the DC voltage. A housing contains each of the solar energy receiver, the solar tracking mechanism and the power circuitry in a portable configuration.

Abstract: A modular power backup system has a plurality of smart battery packs for storing electrical energy. Each of the plurality of smart battery packs includes a first power and control connector. A battery pack rack defines a plurality of slots for holding the plurality of smart battery packs. Each of the plurality of slots includes a second power and control connector for interconnecting with the first power and control connector of a smart battery pack of the plurality of smart battery packs. First control circuitry associated with the at least one battery pack rack selectively pools electrical energy from the plurality of smart battery packs into one or more electrical energy outputs.

Abstract: A system and method for tracking a position of the Sun includes a solar tracker controller that generates directional control signals responsive to sensing signals. A solar tracking algorithm controls operation of the solar tracker controller responsive to the sensing signals. The solar tracking algorithm includes a rough tracking mode of operation for causing a pointing axis of at least one solar receiver to point generally in a direction of the Sun as indicated by the sensing signals. A searching mode of operation positions the at least one solar receiver such that sunlight falls on at least one solar cell of the receiver. A fine tracking mode of operation positions a pointing axis of the at least one solar receiver responsive to the feedback signal from the at least one solar receiver.
