SOLARSAN is the sun tracking complex based on the calculation of data received from the GPS receiver. This system consists of a basic module SOLARSAN-M (MASTER), which can work in standalone mode, and module SOLARSAN-S (SLAVE) working only as an actuator. SOLARSAN can be used to position solar concentrators, collectors or panels at right angles to sunlight. Controlling is carried out with the help of actuators or rotary drives, in two planes and with accuracy of one degree. The module has a set of inputs, i.The anemometer connection input for protection against strong wind, the weather vane input for determining the wind direction, the hail and snow sensor input, and photo sensor input for operation in sleep mode during low solar activity. The WiFi module allows configuring the tracker via a web-page or a local network. The built-in MQTT broker allows managing and receiving data via the Internet from around the world.
The units power supply requirement ranges from 12 V to 30 V (plus the HV version of 12 V to 55 V). The complex features an integrated autonomous power supply module, current protection function, short circuit protection function, built-in radio modem 433.92 (315.00) MHz, 100 mW, for data transmission within a range of up to 100 meters to SOLARSAN-S modules.
The complex can work both along one axis and two axes. The IP66 housing allows installing a solar tracker out of doors. The axis of rotation should not be inclined, as this adds declination and causes serious errors in extreme positions from 180 degrees (south).The correct operation of the control module requires to properly install the drives to ensure the fulfillment of necessary conditions. Movement along azimuth should be in the range or 120 - 370 degrees. The initial elevation angle should be in the range of 0 - 20 degrees, where 0 is the position where the panel is perpendicular to the ground.
The final elevation angle should always be 90 degrees. This is the position where the solar panels are parallel to the ground. Movement should be limited not mechanically, but by limit switches installed in the gearbox or on the moving parts of the drives.There should be no obstacles within the entire range of movement. The feedback sensor installed in the gearbox should close the circuit. This may be a reed switch or a hall sensor SS449A. Power cables of the drives should not be contact with any moving parts. The result, especially for parabolic concentrators, depends on the correct installation. The module should be installed within the GPS reception area. When using three-phase or single-phase AC motors with 110 V or 220 V power supply, a relay should be installed. However, the motor current will not be monitored. To ensure such monitoring, you must install an additional current protection unit. The control system is designed for DC motors. The motors installed in the drives should have the same supply voltage.
The load current of the drives on both axes should have close values. The power supply of the module should be ensured from a separate source with galvanic isolation! The sensor wires should not be located near power supply lines.
It is recommended to use shielded wires, or twisted pair cables, for connecting drives and sensors. The power supply should not exceed the supply voltage range. The power supply should range within 12 V 30 V (plus the HV version with power range of 12 V 55 V). When using SOLARSAN-S, check for reliable radio signal transmission. Also check the operation of SOLARSAN-S at a double distance.To increase the range, stretch the helix antenna of the receiver and transmitter. At the moment of drive movement, set the current threshold so that there is no overload signal. Install the light sensor in a place where there is no shadow. It is recommended to use a photo-resistor of 10 kOhm as a light sensor. When using the module indoors, in an iron box or under a canopy, install an external GPS antenna.
Use the anemometer with an analog output. Also, use a converter to connect an anemometer with a frequency output. The wifi module can only be connected to the module when the power is off.
