What to know about Solar panel installation
Rooftop solar panels turn daylight into electricity for your home. Photovoltaic modules on the roof produce direct current, an inverter converts it into the alternating current the house runs on, and whatever the home doesn't use at that moment flows out to the grid through the utility's meter. Most Canadian homes that go solar stay connected to the grid, drawing power at night and through the winter and sending surplus back on sunny days under a net metering arrangement.

Solar costs in St. Thomas

- Condition and age of the existing wiring
- Panel and service capacity
- Distance from the panel to the new circuit
- Access through finished walls and ceilings

How to choose solar installers in St. Thomas
- Hire a licensed electrician or electrical contractor for any wiring, panel or new circuit work.
- Ask whether the work needs a permit and inspection, and make sure the electrician arranges it.
- Get a written quote that lists fixtures, materials, patching of walls and ceilings, and permit costs.
- For panel upgrades and EV chargers, ask them to check whether your electrical service can handle the added load.
- Choose someone who explains what they found in plain language before starting.
Questions to ask solar installers before you hire
- Are you licensed for electrical work in my province?
- Will you get the permit and arrange the inspection?
- Can my current panel and service handle this work?
- Will you need to open walls or ceilings, and who patches them afterwards?
- Is the price fixed, or could it change once you see the existing wiring?
- What warranty do you offer on your work?
Solar permits in Ontario
Some solar work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in Ontario
Electrical work
Only a Licensed Electrical Contractor can be hired to do electrical work in your home, and the work must be reported to ESA through a notification (permit). A building permit doesn’t replace it. Ask for the contractor’s ECRA/ESA licence number before you hire.

This type of work often has to be done by a licensed or certified trade. Ask to see licences and proof of insurance before work starts.

Common solar questions
Is LokalMatch free for homeowners?

How many pros will contact me?
We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.
Do I have to hire someone?
No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
