Every Solar Installation Company Claims To Be The Best: Here’s What You Should Really Look For in Ontario

Most solar installation companies have an attractive website, social media ads and posts. Full of hope and promises of the best service at minimum cost. Many property owners in Ontario had bad experiences before signing up.

So how do you tell them apart?

Here’s what to check before you pay a deposit.

1. Are They a Licensed Electrical Contractor?

This is required in Ontario. Every grid-connected solar system must be installed by an ESA-licensed electrical contractor. Without a licence, the installation isn’t legal. You also lose net metering, risk voiding your insurance, and your system won’t pass inspection.

Ask for their ESA licence number before deciding. You can check it at esasafe.com. A trustworthy installer will give it to you right away.

2. Do They Actually Install, or Do They Just Sell?

Some companies sign you up and then hand the work to a subcontractor you have never met. If problems happen, no one wants to take responsibility.

You have the right to ask directly who will be working on your roof. Are their electricians part of the company or hired from outside? The most trusted solar installers GTA use their own trained teams, not just whoever is available.

3. Can They Show You Local Work?

A good solar panel installer will have real customers you can talk to. It’s not just about online reviews; it’s about actual people in your area you can call.

Ask for references from recent jobs in the area. If they hesitate or only give you one glowing review, keep looking. A reliable solar panel installer will always have local references ready.

4. Do They Cover Cottages and Off-Grid Properties?

Not all installers handle cottage solar installation or off-grid setups. These projects require additional planning, specialized equipment, and real experience with battery systems.

If your property isn’t connected to the grid or you want a cottage battery back up, make sure the company has done this kind of work before. Ask for examples. Cottage solar systems differ from standard home installations, and inexperienced crews can make costly mistakes.

5. What Does Their Deposit and Payment Schedule Look Like?

A 10-20% deposit is reasonable. If your installer is asking for 50 percent or more upfront for permits, it’s unreasonable.

Ontario’s Consumer Protection Act gives you rights in these situations. Make sure your contract follows these rules.

6. Are They Insured and WSIB-Covered?

If an uninsured installer damages your roof, it can be hard to get it repaired. And in a more serious scenario, if a worker without insurance gets hurt on your property, you could be held responsible.

Request proof of WSIB coverage and full liability insurance before any work begins. You can check WSIB coverage at wsib.ca. A reputable company will provide this right away.

7. Can They Help With Grants and Financing?

The Canada Greener Homes Loan can give you up to $40,000 in interest-free financing. Provincial rebates can reduce the cost of solar and battery systems by $5,000 or more. Not all installers know how to help with these programs.

A good solar installation GTA company does more than just install panels. They help you get the funding that makes your project affordable. Ask what grant support they offer before you decide. Homeowners miss out on thousands of dollars because their installer never mentioned it.

8. Will Solar Installers GTA Still Answer the Phone After Installation?

This is where many companies let customers down. The installation looks fine, but if something stops working and you call, no one answers.

Check recent Google reviews, not just the top ones. See how the company responds to negative feedback. If a business stops communicating after you pay, they were never truly invested in your results.
