Construction on the Carmanah rooftop solar PV system, which is valued at about $2m, in October 2011 in Markham, Ontario.

The engineering, procurement and construction services for the rooftop solar PV system will be provided by Carmanah.

Carmanah CEO Bruce Cousins said combining Carmanah’s expertise with PowerSteam’s knowledge of the energy industry, and their deep roots in Ontario, puts PowerStream in a strategic situation to make significant in-roads in the feed-in-tariff program (FIT) rooftop marketplace for PV.

To ensure that the project meets the FIT program’s 60% domestic content requirements, Carmanah is constructing a solar array featuring 300W solar modules from Heliene of Sault Ste.

The project between Carmanah and PowerStream is scheduled to be commercially operational in early 2012.

PowerStream is an electricity distribution company in Ontario, delivering power to about 330,000 customers in communities located immediately to the north of Toronto and in Central Ontario.

Canada-based Carmanah is a provider of renewable and energy-efficient technologies.
