Solar Installer · Milton
Panels, inverters and batteries, connected under Ontario's net metering rules. Southface Solar will handle the building permit, the ESA notification and the utility paperwork before a single rail goes on the roof.

About us
Southface Solar started installing rooftop solar when the panels were expensive and the paperwork was worse. The approach has not changed: an honest production estimate first, tier-one equipment, every mount flashed into a rafter, and the ESA inspection and utility connection handled without you chasing anyone. We size systems to what a house actually uses, we say so when a battery or a bigger array is not worth the money, and we are still around when the inverter needs a look in year twelve.
What we do
Big jobs and small ones, across Milton and the surrounding area.
Roof-mounted arrays using tier-one modules from Canadian Solar, Silfab or Heliene with Enphase microinverters or SolarEdge optimizers, laid out from a shade and orientation study rather than a guess. Every mount is flashed and lag-bolted into a rafter, and the system meets Section 64 of the Ontario Electrical Safety Code, rapid shutdown included.
Tesla Powerwall 3, Enphase IQ Battery or FranklinWH systems that keep the fridge, furnace fan and sump pump running through an outage and shift your usage off peak on time-of-use or ultra-low overnight rates. Wired through a proper backup gateway so nothing ever backfeeds the line crew's grid.
We file the connection application with your local utility, whether that is Hydro One, Alectra, Toronto Hydro or a municipal utility, and coordinate the bidirectional meter swap. Under Ontario's net metering regulation, the power you export is credited to your bill and the credits carry forward for up to twelve months.
Rack or pole systems for rural properties where the roof faces the wrong way or sits under trees, with the trench, the conduit and the disconnect done to code. Sized to the service and the acreage, and permitted through the municipality where the size requires it.
200 amp service upgrades and solar-ready panels with the bus rating and breaker space for an array, a battery and a Level 2 EV charger, all counted in one load calculation to the Canadian Electrical Code. Done under one ESA permit instead of three separate visits.
Roof-mounted arrays usually need a municipal building permit for the structural load, and every system needs an ESA notification and inspection before the utility will connect it. We handle both and hand you the Certificate of Acceptance to keep with the house.
A system that stopped producing, a dead inverter or microinverter, or an array that has to come off for new shingles and go back on afterward. We read the monitoring data before we drive out so the visit actually fixes it.
Off-grid arrays with battery banks and generator integration for cottages and outbuildings beyond the last hydro pole. Sized to how the place is actually used, weekends in July or all winter, so the batteries are not empty by Sunday morning.

FAQ

In most of southern Ontario a well-placed roof produces around 1,100 to 1,200 kilowatt-hours a year for every kilowatt installed. Payback depends on your rate plan, how much of the power you use yourself and what rebates are running at the time; a typical house lands in the ten to twelve year range against panels warrantied for twenty-five. We give you a production estimate and a payback number in writing before you sign anything, and we tell you plainly if your roof is a poor candidate.
Your utility swaps in a bidirectional meter. Power you use straight from your own panels never shows on the bill, power you export is credited at the same rate you pay, and the credits carry forward for up to twelve months under Ontario's net metering regulation, so a sunny July offsets a dark January. You still pay the fixed delivery charges and you cannot be paid cash for a surplus, so we size the system to what you use, not to the biggest thing that fits.
Panels sit at the roof pitch, and snow slides off smooth glass faster than off shingles once the sun hits it. Production in December and January is a fraction of June, and the annual estimate we give you already accounts for that. Please do not go up and clear them; the risk is not worth a few dollars of electricity.
South, southeast or southwest facing with limited shade is ideal, though east-west roofs still do well. The roof should have at least ten to fifteen years of life left; if it does not, reroof first, and we coordinate with your roofer and install once the new shingles are on. Every mount is flashed and bolted into a rafter, and the building permit covers the structural check.
Not for net metering, where the grid is effectively your battery. A battery makes sense if you want backup through outages, if you are on time-of-use or ultra-low overnight rates and want to shift usage, or if you are rural and outages last. A Powerwall 3 or Enphase IQ Battery costs roughly as much as the array itself, so we run the numbers both ways and let you decide.
Programs come and go. Ontario's Home Renovation Savings Program has offered rebates on rooftop solar and battery storage, and the federal Greener Homes Loan has offered interest-free financing. Nearly all of them require a licensed contractor, a permit and specific documentation. Ask us before booking; we install to the program requirements and help with the submission.
