Sharrett goes solar

August 29, 2011

HAGERSTOWN — The Sharrett Auto Stores business along Dual Highway is among a growing number of local companies that have turned to solar systems.

Construction on the 429-module, 100-kilowatt hour system started on the roof of the car dealership’s Volkswagen, Mazda and Subaru showroom and service center around February, according to Will Perryman, president of the company.

The showroom and service center building at the Dual Highway and Interstate 70 interchange is 30,000 square feet, and the panels cover nearly the entire roof, Perryman said.

The switch was flipped on the system about May 5, and the dealership expects to see about a 30 percent to 40 percent savings on its electric bill, Perryman said.

The dealership expects to save more through the sale of renewable energy certificates, Perryman said.

Renewable energy certificates are sold through a compliance program that is in effect in 30 states, including Maryland.

In those states, electric companies are required to supply a certain percent of their electricity from renewable energy sources.

To help meet the requirement, some electric companies purchase the renewable energy certificates that are generated by individual solar energy-generating systems.

Renewable energy certificates, also known as green tags or renewable electricity certificates, represent proof that one megawatt-hour of electricity was generated from a renewable resource.
