Further reduce cost of energy cost can be achieved in Photovoltaic Concentrators. Main disadvantage of existing PV Concentrators are low reliability of solar tracking systems, reduced life of PV modules, higher system and maintenance costs Energystore Group developed Photovoltaic Concentrating Power plants with a minimal cost of electricity PV generates AUS 15 cents/Kwatt and life expectancy not less then 25 years.  ⌠SUNFLOWER STC■ system is more energy-efficient Photovoltaic Solar power systems compared to current mainstream products on the market with twice less  demand in PV modules. Such a big break through achieved by combination of existing  Photovoltaic Solar modules technology  with our market proved Solar Trackers SUNFLOWER ST series and  new invented  Ridge Soft Concentrators with concentration ratio C1.8.  Further 11 % efficiency increase was achieved in Air Cooled System Sunflower STCA system Cooler operating temperature of solar  modules increases the life expectancy of solar modules in concentrators and avoids browning of the EVA encapsulant compare to existing soft concentrated PV systems. The main advantages of Solenergy Photovoltaic Concentrators are:  high reliability, low components costs, installation and maintenance costs, less ground space requirements.  Table. 1   New  designs  used in plants Extra power  compared to existing standard fixed frame design with monofacial modules Encrease PV efficiency due to the concentration effect. 12%  Daily Tracking Frame 30-50% (depends of latitude of  the location)     Seasonal tracking 5-7% Soft concentrators  with concentration ratio C1.8 30-40 % Passive cooling   frame design 5 % Active  air cooling 6 %  Total surplus 88%- 120%   Solar Tracking Concentrator  STC-series Assembly Instruction EASY ASSEMBLY FRAME TRACKER INTRODUCTION Congratulations! You have made a wise investment by purchasing this SOLAR TRACKING CONCENTRATOR. The heavy-duty mount is a collective effort of industry-educated designers and engineers with strength, durability and performance. Innovative, high-performance features combined with proven durability and dependability make the tracker dream for installers and users.  The Polar Mount solar tracking concentrator designed to track sun orbit with using one actuator. Seasonal adjustments can be done with pivot axis adjustment bolt or additional actuator. POWDER-COAT FINISH The finish coat consists of a thermoset resin that provides excellent weather protection.  UNIQUE EXTRUDED BRIDGE RIB  This additional center bridge rib, extruded between the sidewalls, provides more strength than a conventional hollow rib. Standard on all STC Models.  3/4" SHOULDER BUSHINGS   Shoulder bushings (2) provide a maintenance-free smooth polar pivot on the pre-assembled mount.  PRE-ASSEMBLY INFORMATION  PARTS LIST MOUNT BOX:                            1 √ Pre-assembled Mount                                                      1 √Actuator                                                       2 √ Centre Hub Plates                                                      1 √ Bolt Bag                                                      1-Electronic tracker unit  TOOLS NEEDED FOR ASSEMBLY 1 √ 1/2", 7/16■, 10/12■ AND 14■ Open End Wrenches 1 √ 16■ Adjustable Wrench 1 √ Steel Tape Measure 1 √ 7/16■ Socket and Ratchet 1 √ 3/4" Open End Wrench POLE  AND FOUNDATION REQUIREMENTS Tracker model STC-2 STC-4 STC-8 STC-12 STC-16 Round pole, OD mm 50 76 92 92 92 √ 2 poles Square pole, mm   100x100 100x100 100x100 100x100 √   2 poles Height of pole above the ground, min mm 700 1800 1800 2100 Depending of latitude Ground extension 400 800 900 1100 900 Concrete foundation, m3 0.3 0.5 0.8 1.0 0.8x2 SITE SELECTION The location of the Concentrator must have an unobstructed East-North-West  (East-South-West in Northern Hemisphere ) view of the sky. Insure that no large trees, building, etc., prevent a clear sky view. ASSEMBLY INSTRUCTIONS Assemble STC frame  according to Figs Solar module holes should fit exactly to the frame holes Fit reflector to the Solar modules side frame with the self tap screws Setting the Elevation/Declination. Install elevation angle equal to latitude of the installation site with an  Elevation Adjustment Bolt. It is recommended to install  -20 deg less Elevation angle for maximum winter output for the Stand Alone Solar System. For Grid Connected System it is recommended to install +20 more Elevation angle for maximum summer output. Seasonal adjustment of the polar mount increase output of the system up to 5% and can be done manually by Elevation Adjustment Bolt. (Seasonal Automatic Tracking  system available  with STD dual axis trackers)  The Concentrator assembly is now complete. Make sure that all the bolts and nuts are securely wrench tightened. The Concentrator is ready to adjust for tracking.                           Solar Tracking Concentrators specification Model STC-2 STC-4 STC-8 STC-12 STC-16 Total concentrator surface area, mm 1038x1500 2080x1500 3120x2400 4680x2400 6240x2400 Solar Modules SPR90x2 SPR90X4 SPR210x4 SPR210x6 SPR210x8 Maximum Power, Watt     270    540    1260    1890     2520 Tracking East √West, deg. 160 170 170 170 170 Elevation angle , deg 0-80 0-90 0-90 0-90 0-90  Mounting Poles , mm 30-50 90 90 100x100 2 sq. poles 100x100 2 sq. poles Maximum wind speed km/hour 150 150 150 150 130 Linear actuator, inch 6 18 24 36 36 Frame Two Aluminum Channels 60-32-3mm Four Aluminum Channels 60-32-3mm Four  Aluminum Channels 60-32-3mm   Four Aluminum Channels 60-32-3mm Four Aluminum Channels 60-32-3mm Weight without  modules , kg 7 30 45 70 80 Weight of  modules , kg 15 30 60 90 120  Sensor Tracking Controller STU-48 Sensor Tracking Controller are designed for tracking the brightest spot in the sky.

Solar Tracker Controller STU-48 Installation instruction: The Solar Tracker Controller  STU-48 is designed to drive linear actuators with built in limit switches. Warning: please set up extension limit switch correct to avoid damage of actuator. Maximum actuator extension and recommended tilt angle of the frame from horizontal line is 60deg. STU bracket can be fitted on top or bottom part of the frame or modules. In the battery less application (direct connection to PV modules) STU recommended to fit on the East side of the frame.  Two sensors should be in horizontal position, when solar array are facing to the North (South in Northern hemisphere). Connect yellow wires to No1 and blue wire to No2 actuators terminals (inside  the cover actuator circuit diagram indicated No1 and No2 terminal as a ⌠motor wires■) . For ST-2 model: plug in connector inside the cover of actuator.  Connect battery supply voltage 12-48Volt to red and black wires of STU (there is 1 min checking time available, if it is not enough, reconnect red wire again). First check is for correct motor wires connection: block the light on the sensors (by hand or any other object), actuator should move frame to the east position. (If it moves to west, change polarity connections wires to the actuator) Second check is for correct STU sensors position:  two sensors always are pointing the tracker to the brightest spot in sky. Block one LED sensor from the light. Tracker should move in direction of open to the light LED (If it moves opposite, turn over STU unit).
