JamestownNo2 System Size:  4.95 kW DC
Electric Bill Reduction:  35%
Solar Panels: 275 Solarworld Sunmodule Plus

System Description:
This system was installed on a standing seam metal roof of a barn style garage in Jamestown, RI.  This section of the roof faces south-southwest.
This 18 panel installation has been used as a hedge against increased electricity price for a portion of the customer’s electricity bill.
Unique Factors and Challenges:
This installation was completed on a very steep roof, with a slope of 45 degrees.  In addition, the standing seam metal roof required a unique attachment system that pinches the standing seams rather than penetrating the roof into the rafters.
Other Comments:
The grant covered 25% of the installation cost.  The owner of this system valued the financial return as well as the environmental benefits associated with solar installations.
