Scorpius Trackers launches ‘No Bearings, No Maintenance’ solar trackers
SAN FRANCISCO, July 3, 2013 /PRNewswire/ — Scorpius Trackers is the only company in the world to have pioneered a superior tracking technology in their Solar Trackers. This is in the form of a “NO BEARINGS” frictionless pivot, the Vader-xFP, which replaces a bearing in their single axis tracking solution.
About the Trackers
The primary benefit of a tracking system is to allow the movement of the Photovoltaic panels in accordance with the movement of the sun, thereby enabling maximum capture of sunlight throughout the day.
In order to follow the sun from sunrise to sunset the position of the sun is calculated using a high precision astronomical algorithm. The Scorpius Tracker calculates the optimum rotation angle every minute or more, depending on tracker configuration.
The Innovation at Scorpius
Taking the process of intelligent tracking to an even higher level, Scorpius Trackers have used innovative technology to develop a ‘no bearings, maintenance free, frictionless pivot’, the Vader-xFP, which replaces a bearing in their single axis tracking solution.
The Mechanical Design advantage
The USP of the Vader-xFP is its frictionless No Bearing Design. As a result:
- There is no requirement of lubrication for life of the plant (>30 years)
- It is completely immune to dust and
- There is zero wear and tear of mechanical parts
Typically, in a 1 MW installation, 900 of the Vader-xFP are required.
Minimum Power Consumption: Since the mechanism is frictionless, very less force is required to move a tracker. Less than 0.1% of the generated power is consumed for tracking a >1MW plant.
What makes the embedded system unique are some Intelligent Tracking features like:
Back Tracking with azimuth correction
As the tracker panels are arranged in an array, at low solar angles, one panel may shade the panel behind it, hindering its efficiency. This effect is even more in winter when the solar angles are lower. This is where in-built backtracking algorithm increases the efficiency of single and dual tracker panels.
A backtracking algorithm tries to minimize shading and maximize the angle between the panels by taking into account
- The position of the sun
- The spacing between the panels and
- The size and shape of the panels in the array
This results in maximizing plant load factor (CUF) as maximum amount of solar energy is harvested.
Scorpius Trackers have a ‘Turn on, Forget it’ installation mode with:
- In-built GPS (Global Positioning System) sensors
- Real time clock
- Inclination sensors
This allows automatic calculation of the solar position and turning of the solar PV panels both from east to west and up and down to ensure the panels always follow the sun’s elevation and continue tracking.
