Structural review of the existing roof structure to support a 138 kW ballasted PV solar installation.  The open web steel joists (OWSJ) required reinforcement due to the various building additions and increase in snow loads.  JADE Engineers designed the OWSJ reinforcement and monitored the reinforcement and system installation from development to completion.

Much research was done to determine the snow and wind effects of roof top PV solar installations on the roof structure.  There is very little history or research conducted on PV solar installations in winter climates. Preliminary structural roof review of the various roof structures was conducted to determine adequacy to support a solar installation.  It was determined the roof OWSJ was required to be reinforced while panel arrays were strategically located in other areas of the roof.
