Solar 18 needs a small amount of energy to power its tracking system, and motors are derived from a separate unit of photovoltaic elements mounted on the platform. You do not need separate generators or electrical power outlets to power motors and tracking devices. As a result, all of the energy produced by the Solar18 modules are used for electrical needs or for export to the grid. A combination of proprietary technology and specially designed silicon-based lenses, self-powered tracking, and a high-tech tracking module, the Solar18 delivers more solar energy at less cost than traditional PV systems.
