Barston's Child's Play

An SES representative approached the business owner about installing solar on his roof.  The property owner was inclined to investigate this both for altruistic and economic reasons and he was pleased to learn that the economics in DC were remarkably favorable.  SES was engaged to complete the feasibility study and finalize the proposal and agreement.  Because of the age and unique structure of the building, an extensive structural assessment was conducted to insure the viability of using a ballasted (non-penetrating) racking system for the solar array.

The building was undergoing some other renovation to accommodate a new tenant, so SES worked with the project designers and building contractor to insure all roof loads were considered and work completed with minimal interruption to the landlord's active business on the property.  

Installation, commissioning and interconnection went smoothly.  SES currently provides ongoing O&M, monitoring, and objective advice to the property owner on SREC contracting decisions with a third party SREC broker.
