  • Page 6 Operation Operation SB Series 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 flows outward radially, in diverging “stream lines” from the distribution dish.
  • Page 7 Features Features SB2500 The SolarBee with technology includes new features which enhance its performance 35 Degree through more efficient 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.
  • Page 8 Features Features SB2500 For cable tethered anchoring, the north facing panel may be flipped to face the south using a Latch special panel gate. A tethered machine is fixed PV Module Gate and will not rotate, so the north facing panel will receive the least sunlight, unless flipped using the special gate.
  • Page 9 Features Features SB2500 Digital Controller - The digital controller is located near the top center of the SolarBee. Digital Controller 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.
  • Page 10 SB2500 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.
  • Page 11 Features Features SB2500 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.
  • Page 12 Features Features SB2500 Impeller Assembly - The impeller assembly is CAUTION made up of the stainless steel impeller shaft, Moving blade. stainless steel flag indicator, freeze sleeve, Rotating parts and shaft can stainless steel impeller blades, and plastic impeller cause injury. bushing.
  • Page 13 Features Features SB2500 Distributor Dish / Hose The distributor dish, structural members, structural fasteners, and mounting brackets are constructed of stainless steel. Distributor Dish - Near-laminar flow 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.
  • Page 14 Features Features SB2500 Float Arms / Floats The SolarBee contains 3 float arms and 3 floats. The float arms allow vertical positioning of the Turnbuckle machine and the floats provide buoyancy. Float Arms - The float arms are constructed of Float Arm stainless steel components.
  • Page 15 Features Features SB2500 If the distributor dish lip is too low, the water coming off the lip will flow just underneath the surface of the pond and the surface will not be renewed. Each float arm is connected to the central machine structure with 1 bolt and 1 pin.
  • Page 16 Features Features SB2500 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.
  • Page 17 Features Features SB2500 Following severe weather conditions (greater than 80-mph (129 km/hr) wind, higher than 4-ft (1.2m) 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.
  • Page 18 Maintenance Maintenance and Field Adjustment SB2500 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 field adjustment procedures. In most applications, it is strongly encouraged that the operator have a boat to perform routine checkups and field adjustment procedures on the SolarBee.
  • Page 19 Maintenance Maintenance and Field Adjustment SB2500 PV Module Cleaning The solar panels are the SolarBee's primary source of energy, so it is important that they be 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.
