SunStalker Solar eTrackers
Xtreme Energetics’ second product will be a fundamentally new kind of solar tracker, called SunStalker. This uses printable transparent electronics obtained under a Technology Collaboration and Licensing Agreement with Hewlett-Packard, together with an XE-proprietary eTracking mechanism, to generate electrostatic forces to actuate tiny optical components internal to the solar panel. As these tiny components move they steer sunlight incident from any direction into the acceptance angle of an underlying solar concentrator. Thus, the SunStalker can, in principle, be used in conjunction with any CPV panel, and when used with SunRise becomes the basis for the XE-CPV system. Manufacturing of SunStalker is expected to begin in 2013.
The key advantage of SunStalker trackers is that they allow us, when used with SunRise, to obtain the greatest amount of energy from the least amount of land. This is significant because, if we seek to replace fossil fuel power with renewable power, then the land area that will need to be devoted to renewable power generation is utterly staggering. Of all possible renewable energy schemes, XE-CPV has the highest energy yield per unit area and can therefore minimize the impact on land use. Few people currently appreciate the scale of land area that is in play. We encourage you to read this staggering article explaining the land use issues in greater depth.
In addition, the integration of low-profile SunStalker eTrackers with HCPV panels enables deployment of HCPV panels in locations that have hitherto been impossible, such as in high wind areas, and on the roofs and facades of commercial buildings and data centers, where energy needs are high and collecting areas limited. Thus, the use of SunRise concentrating panels in conjunction with SunStalker eTrackers greatly expands the market for HCPV panels, and is expected to provide a system that delivers the highest energy density of any solar product on the market, at very low cost.
