Solar & Battery Installer in Stormont, Dundas & Glengarry

A Master Electrician who installs your system personally — ESA licensed, serving the United Counties from Long Sault to Maxville.

The United Counties of Stormont, Dundas & Glengarry cover a lot of ground: river towns along the St. Lawrence, farm country north of the 401, and the City of Cornwall in the middle. Solar and battery backup work well across all of it, but the right setup depends heavily on one question most people don't think about first — who supplies your electricity.

This page explains that difference and points you to the page for your area. Each one covers local utility rules, what a typical install looks like there, and the questions we hear most from homeowners in that part of the counties.

We travel from our Ottawa east end base to SDG regularly. Whether you have a bungalow in Ingleside, a century farmhouse near Williamstown or a newer home in Cornwall, Ontario, the person who quotes your job is the person who installs it.

Hydro One vs. Cornwall Electric: why it changes everything

Outside the City of Cornwall, almost every home in SDG is on Hydro One. Hydro One customers are on the Ontario grid, which means they qualify for the Ontario Home Renovation Savings Program: up to $5,000 for solar and up to $5,000 for a battery installed with new solar. Systems that take the rebate are set up for load displacement and can't be net metered.

Inside Cornwall, Ontario (and a few surrounding pockets), power comes from Cornwall Electric. Cornwall Electric buys its supply from Hydro-Québec rather than the Ontario grid, so its customers are not eligible for the HRSP rebate. Net metering is available through Cornwall Electric, though, so surplus solar can earn bill credits.

So the same 10 kW system can be a very different decision a few kilometres apart. Hydro One homeowners usually weigh the rebate against net metering. Cornwall Electric homeowners skip that question entirely and decide mostly on backup power and long-term bill savings. Check your bill — the utility name is printed at the top — and pick your area below.

Backup power across the counties

Much of SDG is rural, served by long overhead lines that run through bush and farmland. When ice storms or summer wind storms bring lines down, rural repairs often come after the towns are restored. Many homes here are also on private wells, so an outage means no water, no toilets flushing and, in spring, no sump pump.

A home battery handles this quietly and automatically. When the grid drops, the battery takes over in a fraction of a second; there's no generator to start, no fuel to store and no noise for the neighbours. Paired with solar, it can recharge during the day and keep essential circuits running through multi-day outages.

Why a Master Electrician

SDG homes vary more than city subdivisions do: steel roofs on farmhouses, outbuildings with their own services, 100-amp panels that predate the current code, and long trenches to a ground-mount array. Those details decide whether a job goes smoothly, and they are electrical problems first. That's why it helps to have a Master Electrician design and install the system.

True Beacon Solar is owner-operated. The owner is a Master Electrician licensed in Ontario and personally does the installs, so the person who designs your system is the person on your roof and in your electrical panel.

We work under ESA Licensed Electrical Contractor #7016796. Every system gets the permits and Electrical Safety Authority inspection it needs, and we handle that paperwork for you.

Built by our in-house crew — the same four-person team on every install, led on site by Master Electrician Nicholas Piche. You have one point of accountability from the first site visit to the day the system is switched on, and after that if you ever need service.

Frequently asked questions

How do I know if I'm on Hydro One or Cornwall Electric?

Look at the top of your electricity bill. If it says Cornwall Electric, you're not eligible for the Ontario HRSP rebate but you can net meter. If it says Hydro One, you're eligible for the rebate (with the no-net-metering trade-off).

Do you really travel to SDG from Ottawa?

Yes. We schedule SDG site visits and installs regularly, and the same Master Electrician handles your job from the first visit to commissioning.

Which batteries do you install?

Tesla Powerwall 3, Sigenergy SigenStor and FranklinWH aPower S. The right one depends on how much of your home you want backed up and what solar you have or plan to add.

Can you install solar on a farm building or in a field?

Yes. Ground-mount arrays are common on acreage in the counties, and barns or drive sheds can work too if the structure and service are suitable. We assess both during the site visit.

Do I need a permit and inspection?

Every install gets an ESA inspection, and some need a building permit depending on the township and the type of system. We handle the applications for you.
