The footprint for the array itself will be approximately 32,522 square feet with periodic gaps <br />between rows and a 20-foot perimeter between the outer edges of the array and the edge of <br />the roof area. <br />tenKsolar, Inc. is headquartered in Bloomington, Minnesota USA and has been selling its new <br />generation of solar technology since 2008. At the core of this technology is the proprietary <br />RAIS-WAVE module architecture (Redundant Array of Integrating Solar), in which cells in each <br />module are interconnected redundantly in mesh rather than series. When combined with a <br />unique digital control algorithm and embedded low-voltage redundant electronics that were <br />also developed by tenK, the module eliminates nearly all of the serial constraints found in other <br />solar modules. <br />To extend this redundancy from the modules to the grid, and take full advantage of the <br />proprietary control methods in the module, a simplified conversion process is used to create <br />grid-quality alternating current (AC). A proprietary stepped-pulse transformer (SPT) technology <br />uses a simplified set of automotive-grade, low-voltage electronics to step-pulse the energy into <br />a solid-state transformer. Unlike conventional inverters, no active electronics are exposed to <br />grid-level voltages, improving up-time performance and reducing operating and maintenance <br />costs. The technology also uses fully embedded, anti-islanding controls that have been third- <br />party validated and certified for U.S. and many international solar markets. <br />Because of the controls residing in its electronics, tenK is able to interconnect SPTs in parallel, <br />allowing the AC conversion process to operate redundantly. If one fails, the energy that would <br />normally be lost is able to flow to another SPT. At times of low solar radiation, a reduced <br />number of SPTs still operate, improving overall system efficiency. As a result, each tenK solar <br />installation delivers full, 480-volt AC grid-quality power directly from the array. <br />Within the array, the maximum voltage of any DC component is 60 V, compared to conventional <br />arrays at 600-1000 V, and each module has full, built-in ground-fault and arc-fault protection. <br />The modules are intelligent, and can sense an active connection. In case of a fire, de-activating <br />the system from the grid anywhere on the AC side causes the modules to stop internally, <br />avoiding safety issues for firefighters and first-responders. These same safety and embedded <br />assembly features also simplify the installation process. <br />The RAIS-WAVE module control technology and stepped-pulse transformer technology are ideal <br />configurations for integrating energy storage directly into the system without additional <br />electronics or infrastructure. And due to its phasing controls, the system can also be used to <br />actively balance phases. <br />Beyond the improvements in reliability from eliminating all single points of failure and the high- <br />voltage active electrical components in conventional solar arrays, tenKsolar panels take <br />advantage of cell independence within the module to add illumination from static reflection. A <br />proprietary spectroscopic reflector-based racking system developed by tenK and 3M gathers <br />additional light from the unused gaps in typical solar arrays to increase energy delivered by the <br />system. This results in a much higher level of energy density for the system as a whole. <br />With its low-voltage systems design and integration, tenK is able to manufacture and sell its <br />product at competitive pricing. The non-reflected efficiency of a tenK system is at or above <br />
