Your Solar Tracking Strategic Advantage Michael Orshan Executive Director P4Q Suntack
The Opportunity! Over the next 10 years  $1.2T  of solar energy will be installed and over 1/3 need trackers Green Media
Parts of A Solar Tracker :  http://www.projectfreepower.com/2008/07
Motor is Key to Tracking  Success Major Motor Topics Motion mechanics Machine controller Controller instructs the engine What is being sensed How to react Where to move to When to move
Controller Essentials Types of Technology Movement options Sun positioning Precision Access to Manager Motor power options Sensors supported Wikipedia
Controller Capable of All Technologies? PV Concentrated PV Solar Tower  Thermal Power
Can the controller handle  dual and single axis options? CPV requires dual axis PV can be dual or single axis CSP is single axis Towers are dual axis
How does tracker find sun? Timer Method Place the array Southeast and let the timer run on expected route Pro:  Inexpensive Con:  Misses a lot of light, inaccurate, lower energy output Sun sensor only Array continuously searches for strongest light Pro:  Inexpensive logic Con: Uses energy to find sun Closed loop manual entry Input longitude and latitude Pro:  High level of precision Con:  Clouds and shadows effect light input
How does tracker find sun? Closed Loop GPS Uses GPS to find the sun Pro:  High level of precision Con:  Additional GPS costs, clouds/shadows Closed Loop with Sun sensor Uses a sun sensor for minor corrections Pro:  Higher level of precision with clouds Con:  Must limit the amount of movement to save power Closed Loop with Sun sensor and Backtracking Uses the sensor to limit shadows on other arrays Pro:  Highest Level of Precision Con:  Must limit the amount of movement to save power Backtracking
How accurate is the controller? CPV and Towers requires 10 th  of a degree PV and CSP can be less accurate “ The more accurate the more power generated” http://www.dailykos.com/story/2009/11/25/804559/-Oz-Solar-TechnologiesWith-Poll
How to configure  via Hardware? Manually Go into  every  box, configure via jumper cables Pros:  Simple Cons:  Time consuming, static, no security-anyone can change this
How to configure  thru software? Computer Interface Direct to Device only Pro:  Simple interface Con:  Must be on site Direct/Wireless to Server Pro:  Can customize data display Con:  Closed system; proprietary interfaces Direct/Wireless to Network Pro:  Easy to access and move data to open managers Con:  Open data requires mapping
What Motor options? Hydraulic  Used to move heaviest items Requires about 6.3amps AC  Used to move fairly heavy items Requires about 1amp DC Brushed or Brushless Used for fairly heavy to really light items Requires about 400 watts
What types of sensors? Sun sensors for amount of light Sun sensors for shadows Inclinometers for angles Anemometer for wind speed
You might ask whether one controller does all of this…
SuntrackPro Does it All Capable of all technologies Single or dual axis Closed Loop with Sun sensor and Backtracking Accurate to a 10 th  of a degree Direct/Wireless to Network  Can use Hydraulic, AC, or DC motors Uses all sensors
SuntrackPro Approaching 500MW installed by 2011
Let’s Talk If You… Want product flexibility Need a high volume partner Demand an experienced engineering staff Require a price that keeps you  competitive
