Recent Trends and Developments

  • Eternegy installed its Solar Kites at the Mediterranean Sea and in Eilat at the Red Sea in March 2013. It can collect 40 percent more power from the sun on a daily basis, with an investment that costs about the same as a fixed panel installation.
  • TITAN TRACKER set up its CPV tracker in Gujarat, India in May, 2013. It is the only solar tracker which has part of its structure in an advanced position: placed in front of boards or parabolas without casting shadows.
  • Multiple rows of PV modules were constructed in August, 2013 at Hoffenheim, Germany. The rows are connected by a rotating drive-train, which is powered by a motor. This drive-train turns several rows of modules to track the sun throughout the day. The design provides sitting flexibility for varied terrain conditions as the drive-line can be installed at varying angles. It also uses fewer motors per megawatt, which increases long-term reliability by reducing potential failure points.
  • Rusnak Jaguar Dealership, Pasadena, California has developed sun tracker skylights. These skylights are basically a mini, fully-autonomous sun tracking motor which uses GPS to align itself and a solar electric panel for power. (August 2013).
  • In March 2014, a new sun tracking system devised by the Arizona State University, USA that provides high tracking precision has been developed using fuzzy logic and image processing. The system consists of two main modes. One is LDR-based that adjusts the orientation of the solar panel approximately, and the other is based on image processing that provides small tracking errors.
  • In May 2014, Artificial Intelligence-Based MPPT Algorithms have been developed by the California Institute of Science and Technology in order to overcome the difficulties post by environmental conditions (especially instantaneous climate changes and partially shading).
  • Exosun’s trackers in France employ a unique grease-free design that enhances system reliability and minimizes long-term O&M costs; constructed in July 2014.
  • NEXTracker120 constructed its dual-axis solar tracker in September 2014 at Atacama, Chile is the first horizontal tracker on the market with a UL-certified self-grounding design that does not require separate parts. These attributes eliminate many of the design, cost and performance constraints associated with typical linked-row trackers.
  • DuraTrack HZ installed its single-axis solar tracking system at Lancaster, CA in November, 2014 which consists of a customized 120° range of motion enabling it to be 20% more efficient than other solar tracker systems.
  • Frankenstein Solar-Power Tracking System (STS) deployed its single axis solar tracker system at Worcester, MA in November, 2014 is a complete solar thermal system designed to automatically adjust the position of its solar panels throughout the day to receive an optimal level of direct sunlight.
