The SolarBee is designed to circulate water
by bringing water from below and sending it
out across the top in a thin layer causing a
mixing effect. The laminar layer ows outward
radially, in diverging “stream lines” from the
distribution dish. As it does, vertical ow is
induced in between the water being drawn
below and the water above. At the level of the
ow intake, water is drawn from all corners of
the tank. As this lower layer of uid makes its
way inward with converging streamlines to the
SolarBee, the water is forced upward, toward
the surface, providing gentle mixing and
de-stratication.
The SolarBee obtains all the energy it needs
from the sun. Its solar panels provide power
to the onboard battery which energizes the
drive system’s controls and motor. Excess
solar energy is stored during the day and
used during the night allowing the SolarBee
to operate during the night without being
connected to the grid.
During operation, a visible ow can be
observed coming off the distributor dish
and spreading outward. The impeller of the
SolarBee is designed to operate at full speed
when there is sufcient sunlight and battery
charge. The rpms may drop down some
during the later night and early morning when
the battery uses up its charge after a longer
period of overcast days. In severe sunlight
limited conditions, the machine may slow
down or stop temporarily to protect the battery
from damage.

The SolarBee with technology includes new
features which enhance its performance
through more efcient and durable components,
improved operation monitoring capablilities, easy
component access, and a robust frame structure.
Solar / Electronics
Photovoltaic (PV) Modules -The PV modules
are often referred to as the solar panels. The
SolarBee uses 100% solar energy to provide
day/night operation. The PV modules collect
solar power to operate the machine with excess
left over to charge an onboard 12-volt, deep
cycle battery. The SolarBee has an 80-watt PV
modules which individually connect to the digital
controller. A bird deterrent is located directly
above the PV modules to prevent bird fouling.
The PV module is generally placed on a low
prole structure which encloses the controller and
battery. The PV module is positioned so it faces
the direction of best sunlight.
The low prole solar panel stand offers additional
protection by providing shading while also
allowing ventilation. Keeping the temperature
down inside the digital controller and the battery at
a lower temperature which extends the life of the
battery and electronics.
Deep Cycle Battery - The deep cycle battery
stores excess power from the PV module during
the day and operates the machine using the
stored power during the night and extremely
overcast days.

Digital Controller - The digital controller is located
inside the the low prole solar panel stand. The
digital controller operates and monitors the SolarBee.
The digital controller is programmed with application
specic run schedule, fallback rpm, and battery charge
settings. The SolarBee's Design and Application
Engineering groups are constantly reviewing the
program to optimize operation. The digital controller
can be updated with a new program (rmware) using
a SD (Secure Digital) Card, similar to that of a digital
camera's memory stick.
All solar energy collection and motor operation are
managed by the digital controller. This component
has two primary functions: (1) To direct and divide the
power being collected by the PV module(s) between
the brushless motor and battery. (2) To serve as the
main control center that operates the brushless motor.
There are 3 PV module connections located on the
front face of the digital controller. If the onshore power
accessory was purchase, a connection will be located
on the right side face. The onshore connection is
used only in applications where onshore grid power is
desired.
The left side face of the digital controller contains the
brushless motor connection, battery connection, and
On/Off switch. The On/Off switch activates power
to the motor. When the switch is turned to the Off
position, the motor will not operate. The charging
function of the controller will continue to charge the
battery even when the switch is turned off.
SCADA outputs offering machine operation parameters
reside within the digital controller. Please contact
SolarBee if you are interested in receiving these
parameters.

Motor Controller - The motor controller is located
near the motor just below the top plate of the
SolarBee. The motor controller is sealed in line
with the electrical cord that runs to the brushless
motor.
The motor controller on the SolarBee receives
power and signals from the main control center
located inside the external enlosure. These
signals are used to operate the brushless motor
at the commanded speed. The motor controller
also sends feedback signals back up to the main
control center.
Due to the high frequency of communication
between the motor controller and brushless motor,
the two components need to be located close
to one another. This is the primary reason for
having the motor controller located directly on the
SolarBee.
All electronic connections on the SolarBee
equipment should only be used for the inputs or
outputs that they are labeled and designed for. If
any of the leads going into the electronic controller
are disconnected, be sure when re-connecting to
place them in the proper position.
Wiring - All electric wiring includes corrosion-
resistant, industrial cords with molded, weather
and watertight connectors. The connectors
are indexed to prevent improper wiring. A
general electrical schematic can be found in the
Maintenance and Field Adjustment section.

The brushless motor is built to be very durable.
The housing is constructed of casted aluminum.
The brushless motor runs very quietly and
smoothly. It does not require any maintenance. A
drive shaft extends through the bottom center of
the housing.
Shaft Coupling - The shaft coupling connects the
brushless motor drive shaft to the impeller shaft.
The shaft coupling is located directly below the
brushless motor.
The rotating assembly (motor, shaft coupling,
impeller shaft, impeller) can be removed from the
machine without disconnecting the shaft coupling.

Impeller Assembly - The rotating assembly is
made up of the stainless steel impeller shaft,
stainless steel ag indicator, and stainless steel
impeller blades. The impeller assembly can be
removed by pulling 3 hair pins on the top plate.
CAUTION: KEEP BODY APPENDAGES

The ag indicator is xed to the shaft and used as
a visual indicator of the impeller shaft's rotational
speed.
A food grade oil-lled, Teon freeze sleeve
secured with o-rings surronds the impeller shaft.
The freeze sleeve is free to rotate on the shaft. If
the water should freeze around the machine, the
freeze sleeve will stand still, frozen in by the ice,
but inside the plastic sleeve, the impeller shaft will
be turning.
The impeller blades are welded to a hub that is
fastened to the impeller shaft. The impeller is
designed to gently pump water from below and
can handle up to 3-inch (7.6cm) spherical solids.
The impeller bushing is a smooth collar that the
impeller shaft tip ts into. The impeller bushing
aligns and centers the impeller shaft within the
machine.

Distributor Dish / Hose
The distributor dish, structural members, structural
fasteners, and mounting brackets are constructed
of stainless steel.
Distributor Dish - Near-laminar ow is achieved
by the SolarBee due to its uniquely designed
distributor dish. The impeller rotates while sitting
within the lower half of the distributor dish. The
gentle water movement strengthens the induced
ow effect (water movement occuring between the
lower water layer entering the machine and the
upper water layer leaving the dish).
The top lip of the distributor dish is set
approximately 1-1/2 inch to 2-inch (3.8cm - 5.0
cm) below the surface of the water to achieve best
ow results. The distributor dish depth is set at
the factory and should not need adjustment after
deployment.
Hose - The hose extends from below the dish
down to the oor of the reservoir. The intake
level is generally set just above the oor of the
reservoir. As the water level uctuates, the hose
remains at a xed placement on the reservoir
oor by the use of a torque bar as the extra hose
lays on the bottom. The intake draws water
horizontally into the hose.
The contact between the torque bar and the oor
prevents the machine from rotating or moving out
of place. The machine naturally has a very small
torque due to impeller rotation.

Release Channel / Floats
The SolarBee contains 3 release channels and
3 oats. The release channels allow vertical
positioning of the machine and the oats provide
buoyancy.
Floats - The oat is made from high density
Polyethylene. The oats are lled with a
Polystyrene closed-cell foam for long term
buoyancy. The stainless steel oat tube is molded
into the oat. The oat tube connects the oat
to the release channel and release tube. The
oat is shaped to hug the hose for installation
purposes allowing the machine to be installed in
a 24" square hatch. The oats have a uniquely
designed shape to:
• Minimize space when collapsed around
the hose.
• Minimize the interference with the water
ow on the surface coming off the
distributor dish.
Release Tube - The release tubes are constructed
of stainless steel. They directly connect the oats
to the central machine structure.

Float Assembly - The oat assembly connects
to the core unit in one location. There is no
adjustment necessary for setting the dish depth.
The oat assembly is bolted to the core unit of
the SolarBee to allow the distributor dish lip to
be automatically set to the correct depth below
the surface of the water. The depth may vary
depending on hose length being supported by the
machine and the amount of hose resting on the
bottom of the reservoir due to uctuations of the
water.
Each oat tube is connected to the central
machine structure with 1 bolt. Each oat is
connected to the oat tube by one pin. Each
oat assembly is constructed of the molded oat
and oat tube. The end of the oat tube contacts
the core unit frame when the oat is extended
into place by means of boyancy pressure when
deployed into the water.
If the machine is resting in the bottom of an empty
tank, the SolarBee will be supported against the
oats resting on the oor of the tank. Once water
is brought back into the tank, the machine will self
deploy and begin to oat.

The performance of the Machine has proven
to increase tremendously when its operator
understands the operation of the machine
and knows how to carry out eld adjustment
procedures.
In most cases, the operator have can perform
routine checkups and eld adjustment procedures
on the Machine, by pulling the Machine to the
hatch. A large, expensive boat isn't necessary.
When tank entry is required, an inatable raft/boat
(approximately 6 ft) is deployed inside the tank.
It is extremely important that safety comes rst
every time the Machine is inspected or having
maintenance procedures performed. It is strongly
encouraged that anyone working on or near the
machine follow these rules:

Tank Maintenance
The machine is designed to rest on the oor of the tank in an event when the tank is drained. If the machine is
left undisturbed, the machine will naturally oat and self adjust when the tank is relled.
During the event that a potable water tank is taken off-line for maintenance for re-coating, sandblasting, or
cleaning, a few considerations need to be followed for the care of the machine. The best solution for the care
of the machine is to remove the unit from the tank until the maintenance is complete. Often times there is an
access hatch thru the side of a tank which the machine in most cases can easily be removed. Sometimes this
is not an option and the following guidelines should be followed in the event of interior tank work.
STEP 1: Turn the machine circulation equipment "Off"
if the tank is projected to be dry for more than a few
days. The On/Off switch is located in the machine
electronic controller mounted to the pv module stand.
STEP 2: Cover the entire machine, including the hose
and intake assembly, using a heavy duty tarp. Be
sure to tuck the tarp under the machine to avoid any
sand being collected on the machine in the case of
sandblasting.
STEP 3: The electrical cord and chemical injection cord
will be suspended from the ceiling so extreme care
needs to be taken to prevent damage to the cord and
hose from any abrasions from blasting. Both injection
and electrical may be disconnected and coiled up
under the tarp if desired.
STEP 4: Once the maintenance is complete, remove
the tarp and reconnect the electrical cord and chemical
injection hose (if applicable). The machine may need
to be cleaned from any dust or sand that may have
made it’s way thru the tarp. A key component that
should be checked and cleaned is the impeller bushing
and impeller tip. Please follow the proper procedure
earlier in this section.

STEP 5: Decontaminate the machine by wiping all
machine surfaces using a bleach/water solution and a
towel or cloth. Remove all excess dust, sand, etc. Do
not use a pressure washer to clean the machine.
This may damage the on-board electronics which may
result in improper operation of the machine.
STEP 6: The machine intake needs to be placed in its
original position and the entire hose layed out across
the oor. The hose should not be coiled or draped
over the machine! Reposition the electrical cord
and injection hose so they do not get tangled on any
objects.
STEP 7: The machine is now ready for the tank to be
lled with water and be turned “On”.
Most customers feel that removing the machine
circulation equipment is the best option for the safety of
the equipment. Removing the equipment also allows
for the contractors to perform their work freely and not
have to maneuver around the machine.
