The Situation

A Markham homeowner near our own headquarters wanted to reduce a rising electricity bill and was concerned about upcoming time-of-use rate changes.

Our Approach

Our design team modeled twelve months of usage and proposed a rooftop array sized to offset the bulk of the home's annual consumption, factoring in roof orientation and minor shading from a mature tree line.

The Outcome

The system was installed in two days by our in-house crew, passed Alectra Utilities' net metering interconnection review without delay, and is tracking in line with the original production estimate.

The Situation

A Hamilton warehouse operator was looking to offset rising daytime electricity costs tied to equipment and refrigeration loads.

Our Approach

Our commercial team assessed the facility's roof loading capacity and daytime demand curve, then designed a rooftop array sized for maximum offset against the facility's commercial rate structure.

The Outcome

Installation was completed with no disruption to warehouse operations, and the system now offsets a significant share of the facility's daytime electricity draw.

The Outcome

The completed system has performed consistently with the original estimate through its first full season.
