* This assumes 85% charge and discharge efficiency.
(Notes and Cautions Regarding Use)
(1) When the photoreceptor side of the solar cell is
installed at an angle of 45
°
facing south, the useable
electricity in the average installation in the winter time
will increase by a factor of approximately 1.5 relative to
a horizontal installation; however, the power in the
summer time will fall approximately 15%.
(2) Be aware that the amount of electricity produced
may suffer due to the proximity of trees and buildings.
(3) Be aware that the night light may not turn on if the
unit is exposed to strong external lights such as street
lights.
(4) If the units are stored for an extended period of time,
use the unit only after fully charging in direct sunlight.
(5) See the user specifications for other details and
cautions.
