Operation
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 pond. 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,
de-stratication, and surface renewal.
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. The new
Technology allows excess solar energy to be
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.

Features
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 3 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 modules have 3 angle settings that
are set at the factory based on solar energy
availability unique to the customer's geographic
location. The attest position is a 35 degree
angle for customers located where solar power
availability is greatest. The mid-range setting
position is a 45 degree angle for customers where
solar power availability is moderately available.
The steepest position is a 55 degree angle
intended for winter conditions to prevent snow
and ice buildup from lasting a long time period on
the PV modules (following winter conditions, the
PV modules should be returned to their original
position to maximize solar energy collection).

Features
For cable tethered anchoring, the north facing
panel may be ipped to face the south using a
special panel gate. A tethered machine is xed
and will not rotate, so the north facing panel will
receive the least sunlight, unless ipped using the
special gate. For mooring block anchoring, this is
not an option due to the machine rotating about
the mooring blocks.
Each PV module is xed to a gate that opens up
allowing quick access to the interior components
of the machine. Each gate opens by simply
removing a pin on the latch end.
Onboard Battery - The onboard battery is
located directly below the dish in a stainless
steel compartment. During operation, the
battery is submerged in the water to maintain a
stable-temperature environment that increases
its performance and life. The battery is double
walled to isolate its contents from the water it is
submerged in.
The onboard battery stores excess power from
the solar panels 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 near the top center of the SolarBee.
The digital controller can be easily accessed by
opening the PV module gate directly above and in
front of it. The digital controller is constructed with
a NEMA 4X (IP 66) Enclosure.
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 modules
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 purchased, 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 Medora Corporation 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.

Brushless Motor / Impeller
Brushless Motor - The brushless motor is located
directly below the Top Deck. 4 bolts run down
through the Top Deck and into the housing of the
brushless motor fastening it onto the machine.
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.
CAUTION: THE BRUSHLESS MOTOR WEIGHS
APPROXIMATELY 80 LBS (36 KG). DO
NOT REMOVE WITHOUT DISCUSSING THE
PROCEDURES AND EQUIPMENT NECESSARY
WITH A SOLARBEE SERVICE TEAM MEMBER.
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 and is made up of 3 main
components. These components are called the
upper coupling, lower coupling, and coupling
sleeve. The shaft coupling is designed to allow
quick disconnect for removal of the impeller
assembly. Disconnecting the impeller shaft from
the brushless motor shaft is simply accomplished
by pulling out a pin and requires no tools. The
upper coupling remains attached to the brushless
motor while the lower coupling and coupling
sleeve remain on the impeller shaft.

Impeller Assembly - The impeller assembly is
made up of the stainless steel impeller shaft,
stainless steel ag indicator, freeze sleeve,
stainless steel impeller blades, and plastic impeller
bushing. The impeller assembly is easily removed
by pulling a pin on the shaft coupling.

The ag indicator is xed to the shaft and used as
a visual indicator of the impeller shaft's rotational
speed.
An 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 securely fastened to the impeller shaft. The
impeller is designed to gently pump water from
below and can handle up to 4 inch (10 cm)
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. There
are also small water passages located below the
dish to strengthen 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 inch to 1-1/2 inch (2.5 cm to 3.8
cm) below the surface of the water to achieve best
ow results. The distributor dish depth is set by
rotating the turnbuckles located on the oat arms.
Hose / Strainer - On the SB5000 , the hose is
directly below the distributor dish and the strainer
is located at the end of the hose. The strainer
contains a buoyant oat ball inside that allows the
strainer to draw water from approximately 1.5 ft
to 2 ft (0.45 m to 0.6 m) above solid bottom. The
hose is designed to make a "J" shaped bend at
the bottom so that the strainer does not draw
sediment up from the bottom. The strainer has
a chain connected to it and can be chained up at
more shallow depths if necessary. The chain also
is used for pulling up the strainer to check it for
plugging.

Float Arms / Floats
The SolarBee contains 3 oat arms and 3 oats.
The oat arms allow vertical positioning of the
machine and the oats provide buoyancy.
Float Arms - The oat arms are constructed of
stainless steel components. They connect the
oats to the central machine structure. Each oat
arm has a sturdy turnbuckle. The turnbuckles can
easily be rotated to adjust the vertical height of
the distributor dish. Lengthening the turnbuckle
(rotating clockwise) will raise the lip of the
distributor dish, whereas shortening the turnbuckle
(rotating counter-clockwise) will cause the lip of
the distributor dish to lower.
The turnbuckle and oat arm structure
components are constructed with robust stainless
steel materials allowing the SolarBee to operate
in severe environments without being damaged.
The turnbuckle is self locking. Simply rotate the
handle to expand or collapse the turnbuckle for
dish depth adjustment.
It is important to check the distributor dish depth
routinely. The SolarBee naturally drops into
the water over time due to biomass buildup
and trapped air escaping from the hose. If the
distributor dish lip is too high, the water coming off
the lip may become turbulent and the ow rate of
the machine may be reduced.

If the distributor dish lip is too low, the water
coming off the lip will ow just underneath the
surface of the pond and the surface will not be
renewed.
Each oat arm is connected to the central
machine structure with 1 bolt and 1 pin. Each
oat is connected to the oat arm by 2 pins. The
turnbuckle can be removed from the oat arm by
pulling a pin, but should only be done when the
unit is resting on the shore.
If re-attaching the turnbuckle to the oat arm, be
sure that each threaded end of the turnbuckle
together are screwed all the way in or all the way
out before re-attaching. If threaded ends are not
equally expanded or collapsed before xing the
ends, the turnbuckle will have limited adjustment.
Floats - The SolarBee has 3 oats, made from
high density Polyethylene. The oats are lled
with a Polystyrene closed-cell foam for long term
buoyancy. The oats have a uniquely designed
shape to:
• Minimize the interference with the water
ow on the surface coming off the
distributor dish.
• Have a low prole above the water for
minimizing wind resistance and
offering less exposure to vandalism.
• Avoid being crushed by ice pressure.
• Provide extra buoyancy when needed
without going much deeper into the
water.

Anchoring Systems
The SolarBee uses one of the following anchoring
systems. The mooring block system consists
of submerged anchors and doesn't require lines
running from the shoreline. The tethering system
uses cable that spans across the pond or reservoir
connecting to tethering posts on the shorline.
Mooring Block System - The mooring block
system consists of two mooring blocks made of
high density Polyethylene with smooth, rounded
bottoms. The smooth bottoms prevent any
damage being done to a pond liner or reservoir
bottom. The mooring blocks are concrete lled
and weigh approximately 70 lbs. (32 kg).
Stainless steel anchor chain is used to connect
the mooring blocks to the SolarBee at the oat
plate on one of the oats. The anchor chain
contains swivels approximately every 15 ft (4.5 m)
to prevent the chain from twisting and tangling.
A 7:1 scope is generally preferred for the length
of anchor chain. For example, if the pond is
approximatley 10 ft (3 m) deep, the anchor chain
will go from the rst mooring block out 70 ft (21
m) to the machine. The 7:1 scope prevents the
machine from moving during high wind and wave
conditions. The two mooring blocks are generally
spaced apart along the anchor chain by a distance
approximately the depth of the water. From time
to time, as determined by specic circumstances,
the scope can be reduced to 5:1.
Features
Features
SB5000
Movement of machine - For a SolarBee
anchored by a mooring block system, the
machine may rotate 360 degrees around the
mooring blocks on a radius of approximately
5X to 7X the water depth. For example, a
machine that is in 10 ft (3 m) of water may
travel on a 70 ft (21 m) radius from the
location of the mooring blocks.

10267_20181113
Following severe weather conditions (greater than
80 mph (129 km/hr) wind, higher than 4 ft (1.2 m)
waves, or ice thaw), it is possible for the SolarBee
to drag the anchors and move out of position. If
this should happen, the pond or reservoir operator
will need to re-locate the machine to its original
position.
WARNING: IF MOVING OR DEPLOYING
MOORING BLOCKS CONNECTED TO THE
ANCHOR CHAIN, BE SURE THAT YOU AND
OTHERS ARE CLEAR OF THE ANCHOR CHAIN
BEFORE SINKING THE MOORING BLOCKS!
LOWER THE MOORING BLOCKS INTO THE
WATER SLOWLY. FAILURE TO DO SO COULD
CAUSE SERIOUS INJURY OR DEATH BY
DROWNING!
Tethering System - The tethering system
constists of 2 tether posts or duckbill anchors set
into the shoreline across from one another. A
stainless steel cable is strung across the pond
or reservoir and tied to both tether posts. The
SolarBee has 2 short chains running from two of
the oat plates on the machine out to the cable
line running across the pond or reservoir.
The tethering system is used in applications where
the body of water is very narrow or the Mooring
Block System is not applicable. Following severe
weather conditions (greater than 80 mph (129
km/hr) wind, higher than 4 ft (1.2 m) waves, or
ice thaw), it is possible for the tether posts to pull
partly or completely out of the ground. If this
should happen, the pond or reservoir operator
will need to re-locate the machine to its original
position.

Tethering System
Movement of machine - For a SolarBee
anchored by a tether system, the machine
will have limited movement, however slack
will be left to allow for water uctuation. The
tether line slack will be eld determined
based on tether line span and expected water
uctuation. The SolarBee will not rotate when
it is anchored using the tether system.

Maintenance and Field Adjustment
SB5000
10268_20181113
The performance of the SolarBee 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 applications, it is strongly encouraged
that the operator have a boat to perform routine
checkups and eld adjustment procedures on the
SolarBee. A large, expensive boat isn't necessary.
Our SolarBee eld teams use 12 ft (3.65 m) Jon
boats that work ne for almost all applications.
It is extremely important that safety comes rst
every time the SolarBee is inspected or having
maintenance procedures performed. It is strongly
encouraged that anyone working on or near the
machine follow these rules:
Wear a personal oatation device
Stay focused and alert
Turn the SolarBee off before working on it
Stay clear of parts while they are moving
To turn the SolarBee motor off, turn the On / Off
switch to the off position. To completely power
down the digital controller, remove all power
sources in the proper sequence.

kept clean. Over time, dust collects on the PV
modules or birds are not kept completely off by
the bird deterrent resulting in the panel's effective
surface area decreasing.
TOOLS RECOMMENDED:
Squeegee
Glass Cleaner
Paper Towel or Wash Cloth
STEP 1: Rinse panel face off with water.
STEP 2: Use squeegee, towel, or wash cloth to
clean surface of panel.
STEP 3: Remove any streaks or lms using glass
cleaner and paper towel/wash cloth.
STEP 4: Repeat Steps 1 through 3 for each solar
panel.

Solar Panel Angle Adjustment
The SolarBee technology includes tilting PV
modules to allow for optimal solar collection for
different geographical regions and changing sun
position during the seasons.
Use 35 Degree (Flattest Position):
Where - Locations south of 40 degree latitude.
When - During fall, summer, and spring or year
round if no adjustment is preferred.
OR
Where - Locations north of 40 degree latitude.
When - During summer only.
Use 45 Degree (Middle Position):
Where - Locations north of 40 degree latitude
(Especially Great Lakes Region and Canada).
When - During spring and fall or year round if no
adjustment is preferred.
OR
Where - Locations south of 40 degree latitude.
When - During winter
Use 55 Degree (Steepest Position):
Where - Locations north of 40 degree latitude.
When - During winter season or periods of
abundant snow (The steep angle will help prevent
snow from building up on the panels).
TOOLS RECOMMENDED:
Two 1/2" or 13 mm wrenches
STEP 1: Loosen 2 bolts on each end of the PV
module using 1/2" or 13 mm wrenches as shown
in the gure below.
Bolts
STEP 2: Firmly grip the PV module and slide
it up or down the tracks until it is in the desired
position. For each of the three recommended
angle settings listed, there is a slot in the top
tracks at both ends that the top bolt will drop into.
STEP 3: Once the PV module is in the desired
position, tighten all four bolts.
STEP 4: Repeat steps 1 through 3 for other two
solar panels
