Scotty's worked with Star Harvest, LLC to install this 2 million-watt system. The 2 mega-watt (2 MW) project uses a $.12 tariff premium over retail formerly
offered by TVA's Generation Partners program. It has 7,142 280-watt PV modules, plus four 500 kW SMA 500HE-US inverters.
The project utilizes single-axis trackers made by TTI Solar of Sacramento. In the picture above taken a bit before solar noon on October 7, 2011, south is to the left. The
modules tilt to the east. They will roll over and follow the sun through the day. Developer David Burt calculates
that the trackers boost production by 20% compared to a fixed array.
In order to maximize land space, the
modules do not tilt down toward the south. The benefit of more modules per acre overcomes the loss occasioned by
no tilt to the south. 1 MW requires about 6 acres. 2 MW requires 13 acres due to shading issues by a power
line. The system should produce between 3.1 and 3.2 million kWhs per year. Kentucky passed HB 1 in 2007. This is the first
system of any type to produce power while utilizing HB 1's "Incentives for Energy Independence Act,"
Subchapter 154.27, KRS.
