Deployable photovoltaic array and collapsible support unit thereof

摘要

A deployable photovoltaic array comprising a plurality of photovoltaic modules attached to a collapsible support unit, where said support unit is made up of a pair of laterally spaced similar pantograph. Each pantograph has the form of a plurality of interconnected rhombs made by pivotally joined elongated arms. Two opposite sides of each solar module are attached to a pair of corresponding nearest parallel arms on the opposite sides of said pantograph. Said array in its deployed condition for large solar elevation angles acquires a characteristic staircase-like form. Angles of said rhombs may further be adjusted to achieve an optimal inclination of said solar modules with respect to the current direction to the sun. In the stowed configuration said array may be held in a protecting container, and is readily portable.
