Abstract
A portable solar module cart is provided which comprises a platform, a pair of wheels attached to opposite sides of the platform, a pair of support struts attached to opposite sides of the platform and movable relative to the platform between a first retracted position in which they lie substantially parallel to the platform and a second erected position in which they extend at a selected angle to the platform so that a DC power source can be disposed on and supported by the platform, a solar panel pivotally mounted to the struts, the solar panel being movable on its pivot when the struts are in their erected position so as to be in a perpendicular relationship with an imaginary line connecting the sun and the solar panel, whereby to maximize the solar energy collected by the panel, and means for locking the solar panel in any selected position on its pivot.
