In another embodiment, a method for collecting and storing solar energy with a mobile solar collection device that includes an adjustable solar collecting device, an electronic storage unit, a power connecter, a transport unit, and a controller is disclosed. The method includes collecting energy provided by a sun with an adjustable solar collecting device, and storing electric energy collected by the mobile solar collecting device with the electronic storage unit. The first power connecter is electrically engaged with a second power connector affixed to a structure to feed electricity to a power grid within a building.

Preferably controller 102 is operable to provide an indication to the transport unit 127 to move the mobile solar collecting device 100 away from the structure to one of many predetermined optimum solar collecting locations that are free from obstructions between the solar panel 128 of the solar collecting device 100 and a sun in a yard of a home or an office.
Control Unit 102 adjusts via solar panel controller 108 an orientation of solar panel 128 (also referred to herein as an adjustable solar collecting device 128) by changing an angular orientation of the solar collection device with respect to a horizon to obtain maximum energy from the sun to store in the electronic storage unit or battery.
Control unit 102 directs the transport unit 127 to move the mobile solar collecting device 100 to a location where the power connector 132 of the collecting device 100 electrically engages with the power connector 132 coupled to a structure or building to off load energy in the electronic storage unit 130 to an electric power grid (see FIG. 11) within the structure. Preferably, the controller 102 directs the transport unit 127 to move the mobile solar collecting device 100 to the location where the power connector 132 electrically engages with the power connector of the structure (See FIG. 11) to off load energy in the electronic storage unit 130 to the power grid in response to controller 102 determining the electrical storage unit 130 has collected a predetermined amount of energy. In one implementation, the electric power grid is disposed within a building.
In one implementation, light sensor 120 detects one or more shadows on or adjacent to the mobile solar collecting device 100, and feed a signal to the controller 102 via system sensor 104 to direct the transport unit 127 to move the mobile solar collecting device 100 to another of a plurality of optimum solar collecting locations (See FIG. 2) in response to light sensor 120 detecting the one or more shadows.

An orientation of the adjustable solar collecting device 128 is adjusted to obtain maximum energy from a sun to store in the electronic storage unit 130. In one implementation, an angular orientation of the solar collection device 128 is changed with respect to a horizon. Electric energy collected by the mobile solar collecting device 200 a is stored with the electronic storage unit 130.
The light sensor within device 200 a detects one or more shadows on or adjacent to the mobile solar collecting device 128 and provides the light indication to controller 102. In response, controller 102 directs the transport unit to move the mobile solar collecting device 200 a to another of many optimum solar collecting locations 200 b that are free from obstructions between the solar collecting device 200 b and the sun.
A sensor on collection device 200 a determines the battery 130 in solar collection device 200 a has collected a predetermined amount of energy.

In the process 400, the controller device 300 (FIG. 3) in block 402 performs a system check to determine that all sensors and controllers (previously described) are operational. System check may check a battery charge level, monitor communications, check sensor working condition, and load maps.
In block 402, controller device 300 (also referred to herein as controller 300) performs a control loop to determine if the controller 300 will conduct a first run, a charge operation, or a discharge operation. Such determination is based on the current or previous operating state of the controller. If controller 300 is in its initial operation, it performs the first run learn operation in block 404. If controller has performed its first run/learn operation it performs the charge operation by directing the solar collector 200 to an optimum location and collect energy from the sun. If the controller 300 has determined that the battery has charged to a predetermined level, or that charging is no longer an option (due to weather, user preference or nighttime), controller 300 performs a discharge/return operation.

In block 610, the controller 300 determines the health, rate and change of conditions of the battery charging. If the health/battery charging rate is good (but not best), the angle of the panel can be adjusted by controller in block 612 to receive a maximum charge from the sun. If the controller 300 determines health/battery charging rate is weak, the controller will note that the location may need to be changes and then the controller executes block 606 to determine an optimum location.
If the controller 300 in block 614 determines that the battery is full or that conditions are not ideal for charging (based on a predetermined criteria—time of day, bad weather), the controller 300 in block 616 navigates the solar collecting device 100 home (See FIG. 7) or to a predetermined safe location.
Referring to FIG. 7, a flowchart of process 700 performed by processor 304 when executing the software instructions in application 320 is shown. Referring to FIG. 7, there is shown the discharge return operation 700.
In block 702, controller 300 determines if the mobile solar collecting device should move home or if not move to a safe location. If the collecting device 100 should move to a safe location then in block 704, controller 300 directs the collecting device to move to the closest predetermined safe location.
In block 706 controller 300 using by monitoring sensors (see FIG. 1) determines if the collecting device 100 is closer to the safe location. If it is not the controller directs the collecting device 100 to move in block 704. If the collecting device 100 has reached the safe location, in block 708 the controller 300 directs the collecting device 300 to park and transmits its location to a remote device.
If controller determines that the collecting device should move home, in block 710, controller 300 directs the transport unit to move collecting device 100 toward home.
In block 712 controller 300 using by monitoring sensors (see FIG. 1) determines if the collecting device 100 is closer to the home location. If the collecting device is not closer, the controller 300 directs the collecting device 100 to move in block 710.
