The Ten K DUO is the best performing integrated component solar PV system on the market. Our pre-engineered systems approach gives us control over every aspect of system performance and cost.

The Ten K DUO beats yesterday’s solar arrays in every performance metric, including cost of energy, energy density, reliability, and safety.

Two Ten K Modules are installed in tandem – facing back-to-back to maximize installed DC watts and energy yield per square foot. This is ideal for applications where maximum energy generation is required in limited space. Our shade tolerant design allows more PV modules to be packed into a limited space at a higher tilt angle.

The DUO takes full advantage of the performance gains of the Ten K Module. The wave format eliminates wasted space and provides an area with complete PV coverage. The DUO places the modules at a higher tilt angle than yesterday’s layouts, increasing efficiency during the peak summer months to help maximize energy production.

Wind forces acting upon a rooftop PV system can be divided into 2 categories. Pressure forces occurs when wind collides with the front or back of a module and is greatest at the edge of the array. Lift forces are best thought of in relation to an airplane wing. When wind flowing over an array is moving faster than the wind flowing under the array this results in lift due to pressure differences on each side.

The greater the difference in speeds, the greater the pressure difference and resulting lifting forces. The lifting forces occur throughout an array. Conventional PV systems oppose both of these forces by adding lots of ballast and roof penetrations.

DUO is smarter. The tall peak and structural integrity offered by coupling the module’s shear stiffness into the racking, via integrated frame extensions, allows pressure forces to be resisted by transferring them into the interior of the array, where the entire array can help resist them. The asymmetrical dual tilt greatly reduces lift by allowing the pressure to equalize from top to bottom through the large valley gap. Combined, these features dramatically reduce and can even eliminate ballast, allowing DUO to be used in many places where conventional systems are just too heavy.

Most buildings don’t face directly North-South, so the size of a solar array is sacrificed in favor of slightly better performance. Because the DUO offers complete PV coverage of a space, the performance of the system is virturally unaffected by system Azimuth. At 40° off Azimuth, production only sees a 0.2% decrease. This flexibility makes the DUO the ideal choice for any rooftop, not just the perfect ones.

The Ten K DUO and all Ten K modules have built-in attach points, reducing installation times and labor costs. Fixed installation costs are distributed across a higher energy generation capacity. The result is a more productive system that is cheaper to install that yesterday’s solar.
