Benefits of Solar Energy

Solar energy offers multiple advantages that will enhance your home for years to come.

  • Lowered energy bills: You can dodge the expensive cost of grid-tied power by creating some electricity right where you use it. Plus, many states provide net metering which can allow you to sell your unused energy back to credit part of your bill.
  • Reduced carbon footprint: Solar is one of the universe's most abundant clean energy sources, meaning you can lower or beat your home's dependence on "traditional" sources.
  • Better energy independence: Solar panel systems can keep your home functioning through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with an optional battery backup system.

How To Choose the Best Solar Company in Ontario

The cost and performance of solar panels often rely on the solar company that installed them. Here are some crucial criteria to bear in mind while shopping 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 boilers, HVAC, photovoltaic (PV) systems, water heaters, and pool heaters. Contractors must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar sector's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Ontario

The kind of solar panels you choose decides how much electricity you can generate. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

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

A majority of Ontario homeowners opt for solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to set up, considering both parts and installation. You can see more specific solar cost information in the table.

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 companies use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are solar leases, solar loans, cash payments and power purchase agreements (PPAs). Most solar experts recommend paying cash or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a home or auto loan, you'll pay a set monthly rate with as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) lets you pay a monthly rate determined by the energy you use, as with an electric bill. We generally don’t recommend these two choices because you won't own the panels and cannot use solar incentives. Look for companies that offer several payment plans to find the right fit for your wallet.

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

A 26% federal solar tax credit applies to new residential solar equipment purchased through 2032. Further incentives may be available through local governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Ontario

How much energy and money could I save per year by switching to solar?

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 gaining popularity in Ontario. Some homes already benefit from solar power on-site or through utility grids, and they're backed by a state solar economy with 74255 workers and counting.

Should I expect a boost in my property value after adopting solar power?

Yes, solar energy systems will boost your property value. According to the National Renewable Energy Laboratory, for every dollar you reduce on energy bills, your home value increases 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 few months on average.

What maintenance do my solar panels need, and how frequently do they need it?

To protect your solar system's efficiency, inspections and cleanings every six months are usually enough. In dry or dusty seasons, your panels might need cleanings every one to two months. Your technician can recommend a maintenance schedule. Its team could also do 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 home's electricity usage. Your surrounding shading, panel model, and roof size could also impact your final result. A professional solar company will consider these factors and determine the right array size for your home.

Should I get quotes from multiple Ontario solar companies?

It's wise to obtain three or more estimates before committing to a single solar provider. This allows you to evaluate customer feedback, pricing, warranty options, and product quality. It also helps you gauge an installer's responsiveness, knowledge and reliability, all of which are positive signs.
