In 2015, Today’s Power, Inc. (TPI) unveiled a 300-kilowatt solar array on the campus of the Electric Cooperatives of Arkansas located in Little Rock. The renewable energy resource is a tenKsolar REFLECT solar wave system that is designed to optimize space while delivering maximum energy production. This system is perfect for ground mount or rooftop applications.

When it comes to getting the most energy from each installed watt, the REFLECT system can’t be beat. Taking advantage of the tenKsolar’s module cell-independence, static reflectors are installed on the backside of each wave of the array, increasing the light received and overall production. This makes REFLECT the most productive of any solar power system available on the market, and an ideal choice for projects focused on peak energy production.

Modules in the REFLECT system are installed at a 26-degree tilt, making them more productive than lower tilts when north of the equator. The cell-independence of the tenKsolar module greatly increases shade tolerance, so modules can encounter small amounts of shading without seeing a drop in production. This allows the ten K Solar Modules to be installed at high tilt (increasing productivity) and close together (decreasing space requirements) all while improving energy density. Shade tolerance also allows modules to be installed closer to obstacles on a rooftop, opening up more space for energy production and decreasing the overall footprint of the system.

Following is a partial list of components for the TPI 300-kilowatt REFLECT system located on one acre of land within ECA's campus:

  • 988, RAIS XT 410 Polycrystalline PV Modules
  • 988, RTF-D Reflector Panels
  • 38, RAIS Inverter Bus, 480 Volt, 7.8kW
  • 13 AC Disconnect Kits
  • 6,210 Linear Feet of Delta Rail
  • 15,900 Feet of #2 AL, XLP Secondary Wire

Monitoring energy production is made easy with an eGuage data logging system. Click here to view the energy production and data from the campus array.
