Green Technology

The worldwide demand for regenerative energy is rapidly rising. Today more than 10% of the current consumption in Germany is provided by alternative energy production. Water and wind power are in the forefront, but solar power is gaining importance due to the efficiency of solar panels utilizing intelligent tracking systems. Solar panels deliver optimum performance when fully aligned with the sun.

To achieve this, the panel moves in two axes – (azimuth) and height (elevation). Solar panels with fixed mountings do not deliver their full potential. The performance improvement using a two-axis tracking system can be as much as 40%.

Products from Framo Morat perform their tasks in solar energy plants, as well as wind turbine farms.

For the precise positioning of wind turbine blades, solar cells, or reflectors in harsh environments Framo Morat components and systems will ensure maximum performance.

Framo Morat is experienced in the design and manufacture of drives for solar tracking systems. With the Compacta series for azimuth tracking and the Mini linear actuators, which are used for elevation tracking, a complete and fully developed drive system for different panel sizes is available.

For special applications and larger quantities, Framo Morat is able to fully design and develop a system for a specific project.

The range of our components is comprehensive, from worm, spur, and planetary gears to complex drive systems.
Framo Morat is certified according to ISO/TS 16949:2009 and DIN EN ISO 14001:2005.

Tracking Drive for Mirror Reflectors

This drive, developed by Framo Morat, is used to enable the tracking of mirror reflectors. During its development, great attention was paid to achieving minimum backlash and maximum torque. The drive consists of a servomotor, a 3-stage planetary gear, a worm gear, a position tracking system and two adapter plates. A single drive moves a total mirror area of 330 m².

Tracking of Fresnel Collectors


Nachfuehrung Fresnel KollektorenThe reflectors of a solar thermal power station must make several thousand tracking movements a day for optimum energy yield. Drives must therefore meet maximum demands for robustness and durability, resist the high temperatures and fluctuating dampness, and withstand dust and sandstorms in desert regions. The adjustment drives from Framo Morat thus have a very high enclosure rating and are only made of high-quality, corrosion-resistant materials.

The “Solar Tracker”

solar-trackerThis two-axle tracking system (Solar Tracker) is used to increase the effectiveness of photovoltaic plants. The Solar Tracker aligns the solar module to the sun horizontally and vertically. Framo Morat developed special drive systems for the precise adjustment of azimuth and elevation (± 2°) in which all components – from the drive housing to the cable – have been specially designed for use in harsh outdoor environments. A positioning system developed in-house allows the control of a complete row of trackers with just one drive.

Adjusting the Elevation of Photovoltaic Plants


We have developed special linear actuators for the vertical tracking of photovoltaic modules. They are characterized by low maintenance requirements and high resistance to wind, dampness and temperature fluctuations (dynamic and static loads of up to 50 and 210 kN respectively). Trapezoidal or ball screws are used with or without integrated limit switches. A variety of transmissions and motors are also available.

Components for PV Tracking Systems


Worm gear sets for high torque transmissions of up to 9,000 Nm dynamic and 20,000 Nm static loads are used for the azimuth-drive for tracking systems with panels up to 60 m2.
