Slew Drives for Solar Tracking Solution

Solar

30-year field tested product
  Units Installed Worldwide

Kinematics slewing drives are the most cost-effective solar-tracking solution. They are designed, tested, and guaranteed for accuracy and efficiency for a 30-year field life.

Fixed solar tracking systems produce the highest levels of energy only when the sun is at the optimum angle to the panel. Active systems improve performance and energy production and require slewing drives for mobility. Kinematics’ slewing gears help make solar installations more effective and profitable by supporting movement in both single and dual-axis solar trackers.

Moving enormous solar tracking systems requires slewing gearboxes that offer both multi-plane load-holding and rotational torque. Slewing drives that engage a greater number of teeth offer the maximum amount of durability, power, and performance. The Kinematics hourglass worm technology allows for maximum survivability load-holding capacity during wind storms by engaging 5 to 13 teeth at a time (depending on size) compared to the standard one tooth. With improved strength and stability over typical slewing drives, our drives can support the load of large solar panels and troughs while controlling rotational torque.

Specific Applications


Slewing drives enable active systems to track the sun by adjusting to the Earth's rotation relative to the sun. Solar applications include photovoltaic (PV) trackers, heliostats, solar troughs, concentrated photovoltaics (CPV), and stirling engines. Kinematics drives can be mounted horizontally, vertically, and at tilted angles so an infinite number of orientations are possible.

PV Tracker

PV Tracker

Slew drives enable photovoltaic trackers to track the light from the sun to minimize the angle of incidence between the incoming light and a photovoltaic positioner. This increases the amount of energy produced from a fixed amount of installed power generating capacity.

Heliostat

Heliostat

A heliostat is a device that includes a plane mirror that constantly reflects sunlight toward a set target. Heliostats are computer-controlled and regularly run a latitude-longitude sequence to keep the plane mirrors properly oriented toward the sun. The slewing drive used in heliostats is a dual axis drive that moves like an eyeball, keeping constant focus to the sun.

Solar Trough

Solar Trough

A solar, or parabolic, trough is a large curved mirror that follows the movement of the sun. The slewing drive is mounted vertically on each row to rotate the trough and hold its weight. The mirror's distinctive parabolic shape allows it to concentrate the solar power by gathering an enormous amount of sunlight and reflecting it onto a single point.

CPV

CPV

Concentrated Photovoltaics (CPVs) concentrate sunlight through a lens onto high-efficiency solar cells which increases the amount of electricity that is generated. The concentration decreases the required cell area while at the same time increasing cell efficiency, causing greater energy production even when using expensive material. An extremely accurate slewing drive like those made by Kinematics is essential for focusing the CPV to get the same amount of power in a smaller space.

Stirling Engine

Stirling Engine

The Stirling Engine is an external combustion engine that uses heat from things like gasoline, solar energy, or even decaying plants and focuses it on a power source to drive power production. It's known for its high efficiency, quiet operation, and ability to utilize almost any heat source. This engine is used in the solar energy sector to efficiently power solar tracking equipment.
