It has become widely accepted that single axis tracking increases the production on many utility scale installations. Due to the competitiveness of the market, prices are always trending downward. Improvements in panel and inverter technology and market pressure have reduced the selling price of trackers by 50% or more over the last 3 -4 years. This puts tremendous pressure on manufacturers to innovate new ways to reduce product costs and/or installation costs. One method that will help to reduce both costs is to develop technology to use the solar string to power the drive motor on single axis trackers. Installation costs are reduced because much less wiring and labor are required during construction. This will require technical innovation to work due to many challenges. Some of the challenges include the range of input operating voltages, sudden voltages spikes, certification, tight packaging constraints and, of course, cost. P4Q Electronics has developed the technology to make this possible. The first phase was to develop the DC-DC convertor that could handle the rapidly changing voltage inputs caused by clouds passing over the array. These can be 1500 volt spikes occurring in milliseconds. As part of the this the packaging to insulate that sort of spike was developed as well. This technology is being beta tested in large numbers now. The second phase of the development is develop the system to proved small battery backup to the string-powered controls. P4Q will use its extensive knowledge of battery chemistry and packaging in the this phase. Expect the see this technology available this year!
