Factors that Affect Solar Panel Costs in Ontario
There are many factors that can play into your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
When it comes to estimating the cost of a solar panel system in Ontario, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past electricity bills. Your total cost can increase by about $3,470 for each additional kilowatt you need.Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Ontario, where sunlight is abundant, efficiency can quickly pay off. Plus, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a big investment. That’s why many Ontario homeowners decide to finance their solar panel systems to offset upfront costs.While solar loans make adopting solar energy more accessible for Ontario homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
Lastly, the company you opt for to install your solar panels can play a part in determining how much you pay. Ontario’s solar companies all have different labor costs and add varying upcharges to equipment. You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

EcoWatch's Ontario, CA Solar Cost FAQs
What is the average cost of installing solar panels in Ontario?
The average cost of solar panels in Ontario is about $17,350 for a 5-kW system and $34,700 for a 10-kW system before the ITC, but the real cost will depend on stuff like the model of solar panels you want, what size system you need and how much energy you use.
Should I lease or buy solar panels in Ontario?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your property value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most bang for your buck from going solar.
How will having solar panels impact the value of my home?
Solar panels can increase your property’s value significantly as long as you buy or finance your panels and don’t go for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% with a solar installation."
How often do you have to replace solar panels?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher amount of energy production.
