Terawatt Solar installs residential and commercial solar systems for homeowners and businesses in Kitchener, the hub of Waterloo Region's tech corridor. Our in-house design and installation team serves downtown Kitchener, Forest Heights, Stanley Park and Victoria Park and the surrounding area.
Kitchener marks the western edge of our current install territory, and we've worked on residential projects from Forest Heights to Stanley Park as demand in Waterloo Region continues to grow.
Most properties in Kitchener are served by Kitchener-Wilmot Hydro. Our team handles the interconnection application and net metering paperwork with your utility as part of every installation, so your system is approved to export surplus power back to the grid.
Working with a locally based, in-house installer means the team that designs your Kitchener system is the same team that installs it and handles any warranty service afterward. We size every proposal from your actual twelve-month usage, not a generic package, and walk you through available incentive programs before you commit.

A homeowner in Kitchener was paying well above the Ontario average for electricity and wanted to lock in predictable costs ahead of planned time-of-use rate changes.
Our design team reviewed twelve months of the homeowner's utility bills along with roof orientation and shading, then proposed a system sized to offset the bulk of their annual usage.
The system was installed by our in-house crew and passed Kitchener-Wilmot Hydro's interconnection review without delay, and the homeowner now tracks production against the original estimate through their monitoring app.
