It consists of 51 solar pan¬ els, made of silicon, which'sre'arranged into three interconnected roirV When the array is exposed to the sun, subatomic particles inside the panels are excited by the sunlight and this creates static energy. The static energy is then channeled into the output box, a small metal box att¬ ached to.the underside of each panel, which then passes the energy into a wire. The wires from each of the output boxes converge into a single wire which trans¬ ports the total energy output from the panels to the DC/AC invertor. The function of the invertor is to con¬ vert the static energy from a direct current (DC) into an alternating current (AC), the type of energy available from a common wall socket. The pump motor is then plugged into the invertor and draws on the alternating current as its power source. To ensure that the panels receive the full benefit of tbe sunlight, the array is mounted on a tracking system that gradually tilts it to keep it directly underneath the sun throughout the day. The tracking system is powered by a solar-powered motor and at the end of the day, when the last rays have disappeared over the western hori¬ zon, the motor returns the panels to an east-facing position, ready for the next Thomas said that the tracking mecha¬ nism makes the unit much more efficient than a stationary array which would only receive the full intensity of the sunlight once a day, when the sun was directly over the panels. He said that this is one of only two such tracking units in California. Because the amount of energy produced by the panels is directly proportional to the intensity of the sunlight, Thomas said that on a cloudy day the array will not produce as much energy as when the sky is clear.
