Abstract
An apparatus for collecting solar energy and converting it to electrical energy utilizing solar panels pivotally mounted to a base such that the panels may be pivoted to a storage position inside said base. Additional solar panels may be pivotally mounted on retractable frame trays which stow inside the base when the panels are pivoted to a horizontal position.
Claims6
An apparatus for providing electrical energy from a mobile solar energy power source having collapsible solar energy collecting means, comprising:
- (a) at least one inner solar energy collecting means for collecting solar energy and converting the solar energy into electrical energy, said inner collecting means having an upper end and a lower end;
- (b) a main base including a front and a back thereof, said main base pivotally mounted to the lower end of said inner collecting means such that said inner collecting means is free to pivot about the mounting axis between 0.degree. and about 90.degree. above the horizontal;
- (c) at least one inner support member for each inner collecting means, said inner support member having a first end and a second end, the first end of said inner support member pivotally connected in proximity to the upper end of said inner collecting means, said inner support member comprising an inner leg and an outer leg including respective longitudinal axes thereof, the inner leg slidably mated within the outer leg such that the longitudinal axis of the inner leg is longitudinally aligned with the longitudinal axis of the outer leg, the length of said inner support member changeable by sliding the inner leg within the outer leg along their respective longitudinal axes;
- (d) an inner guide member having a longitudinal axis, said inner guide member attached to said main base such that said inner guide member longitudinally traverses said main base between the front and the back thereof;
- (e) an inner sliding shoe pivotally connected to the second end of said inner support member, said inner sliding shoe mounted to said inner guide member for movement along said inner guide member between the front and the back of said main base such that movement of said sliding shoe along said inner guide member in combination with the sliding of the inner leg within the outer leg allows positioning of said inner collecting means at an angle between about 0.degree. and about 90.degree. above the horizontal;
- and
- (f) means for storing the electrical energy received from the inner solar energy collecting means and supplying the energy to an external receptable.
