Terawatt Solar installs residential and commercial solar systems for homeowners and businesses in Toronto, Ontario's largest city. Our in-house design and installation team serves the Beaches, Etobicoke, North York and Scarborough and the surrounding area.
From century homes in the Beaches to newer builds in North York and Scarborough, Toronto's housing stock varies widely in roof type and age, which is why every Toronto proposal starts with a structural review specific to your property.
Most properties in Toronto are served by Toronto 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 Toronto 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 Toronto 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 Toronto Hydro's interconnection review without delay, and the homeowner now tracks production against the original estimate through their monitoring app.
