This is a project of photovoltaic module for a solar power hybrid. Two 24V, 235W modules from BP are used as batteries. They are connected in parallel, so the maximum power is approximately 0,5kW at 24V. Panels are automatically guided to the sun by means of solar track. When the wind is strong (the wind speed is measured by a simple sensor from weather station), they are automatically parked to the horizontal. The whole mechanism can be home made. The rotation horizontal axis is made of worm gear from conveyor belt, while the vertical is supported by an actuator from the door. Sometimes you have to use specific external limit switches, if you use poor quality gears with limit switches in the actuators.
The system allows the device to follow the sun. It has a very large angle of view – it may be a cloudy day, and only when the sun appears, then the solar module immediately turns to it. After sunset, the collector automatically rotates to the east. The construction and solar panels weight approximately 50kg.
The device is supplied two 225Ah accumulators connected in series. They are connected with 1000W Compac UPS, which was modified, so it can be self-activated. Used APZ automatically switches to the mains voltage, when the driver disconnects the voltage from accumulators to the UPS.
Counter is added to have a preview, how much of ready power was produced (except the UPS consumption, control, etc.).
