The Functionality of Power Structure Explained
1) Sculpture is installed facing south, as to gather the most possible sunlight.
2) Solar panels gather energy in the form of DC voltage.
3) This DC voltage (as monitored and recorded on the back of the sculpture) is fed into an inverter.
4) The inverter is plugged into a typical outlet.
5) Once plugged in, the inverter converts DC energy to AC energy, conditions this energy to match existing currents in the electrical grid, and feeds this converted energy directly into this grid.
6) This converted energy offsets energy usage derived from power companies, and in the case of Power Structure's current installation to the Kemper Museum in St. Louis, is assisting in lighting other works of art within its galleries.
Simply put, if Power Structure is placed facing south, in the sun, and plugged into an outlet, it will replace the power originating from the power company.
