Solartrak{trademark} controller developments for today`s applications

PDF Version Also Available for Download.

Description

The SolarTrak{trademark} array tracking controller, originally developed and licensed by Sandia National Laboratories as a low-cost, high-accuracy, reliable controller for photovoltaic (PV) concentrator arrays, has undergone significant development to make tracking accessible to a much broader segment of the PV market. Hardware and software improvements (1) reduce power consumption for PV/battery- powered applications, (2) enable the controller to connect directly with low-cost, off-the-shelf, television satellite dish actuators, (3) enable on-site setup without an additional input board, (4) increase clock accuracy by providing daily and weekly adjustments to the on board clock, and (5) include a low-cost wind stow sensor.

Description

The SolarTrak{trademark} array tracking controller, originally developed and licensed by Sandia National Laboratories as a low-cost, high-accuracy, reliable controller for photovoltaic (PV) concentrator arrays, has undergone significant development to make tracking accessible to a much broader segment of the PV market. Hardware and software improvements (1) reduce power consumption for PV/battery- powered applications, (2) enable the controller to connect directly with low-cost, off-the-shelf, television satellite dish actuators, (3) enable on-site setup without an additional input board, (4) increase clock accuracy by providing daily and weekly adjustments to the on board clock, and (5) include a low-cost wind stow sensor. The result is a stand-alone tracking system sufficiently low cost and reliable to make 1-kW tracking systems practical for flat plate and concentrating arrays. Results of a year of testing are presented showing clock accuracy better than a minute per year can be maintained.
