Factors that Affect Solar Panel Costs in Ontario

The cost of installing a solar system in Ontario can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is the size of the system your household needs, and other factors include equipment choices, financing options and the solar company you choose.

Solar Equipment

Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of going solar. For that reason, it's important to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use. The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your power bills. Additionally, extra products, such as solar batteries, can bring your total well above the Ontario average.

Solar Financing Terms

If paying for solar panels out of pocket is too expensive, solar loans are a popular route because they reduce your upfront costs and allow you to pay for your system over five to seven years on average. You'll have to consider the long-term cost of financing options, including the amount of interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs considerably.

Solar Panel Installation Company

The solar installer you select will play a role in your total cost to make the switch to solar power. Different companies will bill different amounts for the equipment and labor. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those larger companies.

How to Save on Solar Panels

There are many companies available in Ontario, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be difficult, so here are some tips to help you decide:

  • Contract: Though reading through a contract can be tedious, it's important to do it fully so you can make sure you understand how much the equipment and services will cost and the terms of the warranty.
  • Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: Different companies carry different brands and kinds of panels. If you want a specific brand, make sure the solar panel company you're considering has it.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to install your solar system. Another way you can look into your installer's reputation is by reading reviews.

EcoWatch's Ontario, CA Solar Cost FAQs

What is the average cost of installing solar panels in Ontario?

This is a tough question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have above-average energy consumption. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Are solar panels free in Ontario?

You can't get solar panels for free in Ontario. However, you may still be able to get them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd prefer to own your solar panels, you can finance them with a solar loan.

Is it worth going solar in Ontario?

Whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How many solar panels should I get to power my home?

To figure out how many solar panels you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
