Drives for PV systems and solar tracking systemse
The use of the sun as an energy source has proven itself over many years. Powerful tracking systems are used to capture every ray of sunlight and maximize the efficiency of photovoltaic systems. Solar tracking systems can be used in various ways, depending on the direction in which the PV system is to be positioned. In addition to the swivel movement (azimuth), the tilt movement (elevation) can also be implemented so that the solar modules precisely track the position of the sun throughout the day. Depending on the area of application, single-axis or dual-axis solar trackers are used, which are reliably operated with linear drives or gear motors. However, sometimes a custom-developed drive may be the best solution for fully exploiting the energy generated from sunlight. This makes optimum use of solar radiation, increases the daily energy yield, and achieves a more even feed-in to the grid – which ultimately improves the economic efficiency of the entire system.
Customized drive for tracking mirror reflectors
Framo Morat has developed a drive system for tracking large mirror reflectors in solar thermal systems that meets the highest requirements for backlash and torque. The drive consists of a servomotor, a 3-stage planetary gear, a worm gear, a position tracking system, and two adapter plates. This allows a mirror surface of 330 m² to be moved precisely – with low maintenance and high efficiency over the long term.
Solar tracking systems: Compacta drive for solar trackers
In solar trackers, modified Compacta drives perform precise azimuth and elevation adjustments (± 2°). All components are designed for outdoor use and can withstand wind and weather conditions over the long term. A specially developed positioning system also enables multiple trackers to be controlled with just one drive – a solution that combines stability, scalability, and cost-effectiveness. In this way, the two-axis tracking systems can increase the efficiency of photovoltaic systems.
Elevation adjustment of photovoltaic systems
Framo Morat has developed high-load capacity lifting spindle drives for the vertical tracking of PV modules. These drives offer high resistance to wind loads, moisture, and temperature fluctuations, withstanding dynamic loads of up to 50 kN and static loads of up to 210 kN. Our broad manufacturing expertise enables the use of trapezoidal or ball screw drives with or without integrated limit switches.
Worm gear sets for azimuth slewing ring drives
Framo Morat develops and manufactures high-performance worm gear sets for the precise tracking of large-area photovoltaic trackers. These gear sets transmit dynamic loads of up to 9,000 Nm and static loads of up to 20,000 Nm and are ideal for use as azimuth slewing ring drives in tracking systems with a module area of up to 60 m². The robust design guarantees reliable movement even under high wind loads and ensures that the panels are always optimally aligned with the sun. The drives thus contribute to increased energy yield and a consistent grid feed-in – over many years, with low maintenance and high resilience.
Wheel hub gearboxes for solar cleaning robots
In regions with high levels of dust and sand, our drives ensure the functionality of solar cleaning robots. Robust wheel hub gears provide the drive, planetary gears ensure brush rotation, and linear drives control the lowering of the cleaning units. All solutions are compact, durable, and designed for continuous use in extreme conditions.
