SunSaluter. Full Goh stumbled on the concept through her long-standing interest in
solar energy and experimentation with how
to improve solar productivity.
“One problem that kept coming up was
solar panels’ inability to consistently gener-
ate the amount of electricity the manufac-
turer claimed [it could] throughout the day,”
The SunSaluter’s design consists of a sin-
gle-axis rotator on which a solar photovoltaic
panel is fastened to a hinged frame. One end
of the tracker is attached to a weight and the
other end to a water clock, which is essen-
tially a unified container with a precision
valve. To run the device, the operator fills
User fills originating water
containers with the specified
volume of water and water
begins dripping into the filtration
unit container
Water flows through the
filter and can now be collected
for use at any time
Solar panel rotates due to
displacement, as the east side
gets lighter in weight
Water has fully emptied from
the originating container into
the filter and solar panel rests
facing the west side
Solar panel rotates due to
displacement, as the west
side gets heavier in weight
Water continues flowing from
the originating container into
the filtration unit container
Solar panel is parallel to the
ground due to equal weight on
both sides
