Marble supplier sells solar power to Progress Energy


Raleigh-based David Allen Co. has turned its attention from marble and terrazzo floors to the roof of the company’s headquarters.

The Triangle Business Journal reports the marble, granite, tile and terrazzo supplier recently flipped the switch on a photovoltaic solar energy facility that is one of the largest rooftop photovoltaic systems in the Triangle. It has 700 solar modules covering 23,000 square feet of the rooftop of the company’s warehouse and service building.

The company expects to offset about 35 percent of its current electric expanses with the 170-kilowatt system, which is also interconnected to Progress Energy’s power grid. During times of low energy consumption, the system sends excess energy to the utility, and David Allen gets credit through deductions in its monthly energy bill.

The system was designed and developed by Peak Solar Investors LLC with Barnhill Contracting Company providing installation services. Peak Solar Investors LLC is a company created in 2010 by the principals of residential land development company Five Star Development of NC to help clients take advantage of tax incentives in the renewable energy market.
