Solar Array | Willis A. Smith Construction, Inc.

Array Overview
Phase I: The first solar photovoltaic array installed at the Willis A. Smith headquarters building consists of sixty American-made, Evergreen Solar Inc. silicon solar panels. The total power of the solar array is 12.3 kilowatts, and produces an estimated 20,000 kilowatt hours of electricity per year.

Phase II: In January of 2014, we installed an additional 47.2 kilowatts using two different panel types – one to match the look of the original array and the other to maximize overall production.

Attachment System
The solar panels attach to the new Willis A. Smith headquarters roof using S-5 Systems Inc.’s standing seam panel clamps. These clamps eliminate the need to penetrate the roof system to attach the solar array, and ensure a totally secure, weatherproof, easy to maintain, long-life installation. The S-5 clamp system is available for a wide variety of metal roof systems, including all Butler Building roofs.

The Results
Willis Smith is now net zero energy, with total power of 59.5 kilowatts provided by the sun.
