How To Choose the Best Solar Company in Ontario

The more thorough your company investigation is, the better your solar installation will ultimately work. Here are some essential aspects to keep in mind while searching for a solar company.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar pool heaters, water heaters, HVAC, photovoltaic (PV) systems, and boilers. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. You should also visit a company's website to learn about its private credentials. Two of the most recognized are the PV Installation Professional and Solar Heating Installer certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Ontario

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as battery storage and electric vehicle (EV) chargers, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar company provides these add-ons, so look for a provider that sells them if it's important for you.

You can expect to pay about $17,350 on average for a five-kilowatt solar energy system in Ontario. Use the table in this section to get an idea of what amount Ontario solar companies might quote for your specific system.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,314
Solar Polycrystalline$1,025
Thin-Film$599
Solar Battery$841
Solar Home EV Charger$3,154

Financing Solar Energy in Ontario

Solar installers use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are cash payments, power purchase agreements (PPAs), solar loans and solar leases. We suggest paying with cash or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar incentives to minimize your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to use your panels for a fixed monthly rate, while PPAs let you pay just for the energy you use, similar to an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each provider you're evaluating about the financing options it offers. A salesperson can help you determine the most suitable option for your budget.

The table below lists the average payback periods for different capacities of solar systems in Ontario.

You are eligible for a 26% federal tax credit for new solar energy devices until the year 2032. Local and state governments and utility companies might also offer rebates, discounts, and dedicated financing plans that could save you more.

Frequently Asked Questions About Solar in Ontario

How much money could I save by going solar in Ontario?

Most Ontario homeowners spend about $1,185 on energy each year. Your costs could drop by $1,307.60 for each kilowatt you generate after you pay off a solar array.

Is solar energy widely available in Ontario?

Yes, solar energy is reaching new heights in Ontario. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 74255 workers and counting.

Should I expect a boost in my property value after installing solar panels?

Yes, solar energy systems will increase your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you save on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How long does the solar panel installation process last?

Your solar job's duration will depend on its size and complexity, as well as Ontario's permit and inspection procedures. It could take two weeks to a couple of months on average.

What care do my solar panels need, and how often do they need it?

To preserve your solar system's efficiency, inspections and cleanings every six months are usually sufficient. In dry or dusty seasons, your panels might need cleanings every few months. Your provider can recommend a maintenance schedule. Its team could also handle the cleaning for you.

What size should my new Ontario solar system be?

The average Ontario solar system size is 2.9 kilowatts (kW). However, your final system size depends on your household's power consumption. Your roof size, panel model, and surrounding shading could also impact your final result. A professional solar installer will consider these factors and determine the right system size for your home.

How many estimates should I get before making a final solar company decision?

Yes, we advise asking for free solar quotes from at least three companies. You should review each quote and compare prework scope and costs, labor fees, financing options, warranty details and equipment costs. Ensure each quote offers an itemized financial plan and includes your anticipated payback period.
