 This
solar electric system has been designed and engineered by Kevin
Goodreau of Direct Power and Water Corporation. The electrical
design incorporated 12 "Color Kinetics" Colorburst
LED's to illuminate the artwork for a maximum of nine hours
per nigh. The expected average load of all LED's when illuminated
was expected to be approximately 252 watts. The light show is
directed by the I-Player 2 which is a storage and playback system
for Color Kinetics digital lighting products. With 16MB of on-board
memory, iPlayer 2 accommodates a full DMX universe (170 individual
light addresses). We can create one long show or multiple shorter
shows on Color Kinetics ColorPlay light show authoring software.
The system was installed by B & D Electric of Albuquerque,
New Mexico in conjunction with Direct Power and Water Corporation
of Albuquerque. RLK Sales Corporation (Mr. Kevin Burke) was
instrumental in helping with the overall lighting design and
placement of the LED's at the Yucca. The lighting project was
a collaboration of the three aforementioned companies under
the direction of Mr. Jim Kraft.
 Included
in this design are 6 Sharp 165 watt modules. The modules are
a nominal 24vdc module and each module is fused at the array
in the combiner box. Five of the six modules are wired to
the Outback Power Products MX60 charge controller and one
module is wired to the Morningstar lighting controller. The
Morningstar charge controller is a pulse width modulated charge
controller and also serves a light controller for the LED's.
When the voltage is < 3vdc (when the sun sets in the west
sky) the Morningstar lighting controller closes a FET in the
controller and sends a signal to a 24vdc coil relay. When
the coil closes 120vac power from the Exeltech 600-24 inverter
energizes the four PDS150e power supplies, the I-player and
then the LED's are illuminated. The length of illuminated
is determined by the Morningstar controller. Currently the
controller is set for eight hours.
This array will produce a maximum of 990 watts of power in
full sun. Electrical production of this array is expected
to be between 79,200 and 81,840 Watt hours per month. This
figure is calculated based on a tilt angle of 45º.
