Terawatt Solar installs residential and commercial solar systems for homeowners and businesses in Mississauga, Peel Region's largest city. Our in-house design and installation team serves Streetsville, Port Credit, Meadowvale and Erin Mills and the surrounding area.
Mississauga's mix of established subdivisions and newer condominium-adjacent townhome developments means roof conditions vary block to block. Our design team has installed systems from Streetsville through to Port Credit and Erin Mills.
Most properties in Mississauga are served by Alectra Utilities. 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 Mississauga 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 Mississauga 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 Alectra Utilities's interconnection review without delay, and the homeowner now tracks production against the original estimate through their monitoring app.
