Canadian Solar – Solar Panel Review

Canadian Solar Panel Review

Many countries have realized the harmful effects of fossil fuels and are trying to reduce their carbon footprint. Technology is improving, and countries are adapting to new ways to use renewable and sustainable energy. Consequently, the entire renewable market is on the rise.  Especially, the Australian renewable industry is booming because of multiple government rebates and incentives to encourage energy efficiency. As a result, solar energy solutions have seen a positive shift since solar is a huge part of renewable energy. This brings us to the “Canadian Solar – Solar Panel review.”

Overview of Canadian Solar

Canadian Solar is a Tier 1 solar panel company. This company has been in business for over 20 years. Dr. Shawn Xiaohua Qu established Canadian Solar in 2001. He remains the Chairman, President, and Chief Executive Officer. Canadian Solar was listed on the NASDAQ in 2006. Although the majority of its production is in China, Canadian Solar has two manufacturing facilities in Ontario, Canada.
According to Bloomberg NEF, Canadian Solar has the world’s fifth-largest solar panel manufacturing capacity and is expanding its presence in Australia. They have four warehouses across Australia and employ 50 locals in solar panel sales and service, as well as large-scale solar farm projects.
In March 2020, the Canadian Solar research and development team created an n-type poly-crystalline silicon solar cell with a world record efficiency of 23.81%. The world’s most efficient residential solar panel currently has an efficiency of 22.6%. 
Over the years, they have grown to be one of the biggest solar panel manufacturers in the world. Their production capacity is almost 2.5 gigawatts per year. Their panels are popular among homeowners and businesses because they are high-quality, affordable, and because they have the Tier 1 title. 

What is a Tier 1 Solar Panel?

You may have encountered the term Tier 1 while researching solar for your home and wondered what it meant.
Solar panels have 3 categories – Tier 1, Tier 2, and Tier 3. Tier 1 is the more efficient and reliable. Therefore, you should always choose the Tier 1 category. Tier 1 solar panels are known for their long lifespan, so their 25-year performance warranties will be honored. Their automated manufacturing techniques reduce the possibility of defects, and their long-standing reputation ensures that any problems arise are resolved.
A variety of factors are considered when determining Tier 1 solar panels. 
  • At least 5 years of experience: This ensures that they are a reliable source of solar energy and are respected enough to withstand the test of time while remaining financially secure.
  • Public trade and strong balance sheet: These companies are more reliable because they have previously been subjected to specific standards and have been declared worthy of investment.
  • Strong manufacturing techniques and strong vertical integration: This results in increased productivity and more efficient material utilization. Also, it ensures safe and high-quality solar products.
  • Invest heavily in marketing: A growing market reflects brand confidence and a desire to invest in quality control. 

Range of Panels 

Canadian Solar manufactures solar panels for residential, commercial, and utility-scale applications that are reasonably priced and have a good reputation for quality and dependability. Like most large-volume manufacturers, Canadian Solar has switched to higher efficiency mono PERC half-cut cells in almost all new generation panels. The HiDM module, manufactured in Canada, is the sole exception, employing a special shinged mono PERC cell configuration.

To get the best price, you should get multiple quotes from Canadian Solar. Checking out different products might help too. The final price depends on the equipment you get, based on your product. More specifically, the kind of inverter or battery you need with your panel depends on what panel you get. Most Canadian Solar PV systems are priced between $2.70 and $3.20 per watt, making them an excellent value in the home solar market.
This means that the gross cost of a 6 kW system (before any tax credits or other incentives) would range between $16,200 and $19,200.
Furthermore, most homeowners pay far less than the total gross cost. With the federal solar tax credit of 26 percent, a 6 kW system with Canadian Solar panels would cost between $11,988 and $14,208. And everyone is eligible for the said credit. Numerous state-level solar incentives and rebates are available to help you further reduce your upfront costs. 
The table provides below is not an exact amount. Rather, it’s an approximate amount. Check out the best solar packages here. 
System Size (kW).Average cost (with installation)
6kW$11,988 – $14,208
8kW$13,500- $15,650
10kW$16,550- $17,900


“Solar panel efficiency” refers to how effectively a solar panel captures and converts sunlight into usable electricity. A high-efficient solar panel can produce more electricity than a lower-efficient panel of the same size under the same conditions. As a result, a higher efficiency rating is generally preferred.
The efficiency of your Canadian Solar panels will differ depending on the model you select for your system. The efficiency rating of Canadian Solar panels ranges from 15.88% to 20.60%.

Performance (temperature coefficient) 

The temperature coefficient indicates how well your solar panel will perform in less-than-ideal conditions. Like other electronic equipment, solar panels perform better when kept cool (ideally at temperatures around 25° C/77° F). The temperature coefficient indicates how much your panel performance will change during hot, sunny summer days.
Your solar panel’s electricity production decreases by a temperature coefficient for every degree above 25° C (77° F). The temperature coefficient of the Canadian Solar CS1H-325MS panel from their HIDM residential series, for example, is -0.37%/°C. This means that if the temperature of the panel rises by one degree, from 25° C (77° F) to 26° C (79° F), electricity production will fall by 0.37%. If the temperature rises to 35° C (95° F), electricity production will fall by 3.7%.
Your solar panels will most likely see a few hot and sunny days throughout the year, so they should have the lowest temperature coefficient possible.
The temperature coefficient of Canadian solar panels ranges between -0.41 and -0.35.


Whether you’re purchasing a television, a car, or solar panels, the manufacturer should provide a strong warranty. The materials warranty (also known as the product or equipment warranty) of a solar panel is a guarantee from the manufacturer that they will replace your panel if it fails due to manufacturing defects or environmental issues.
Depending on the product line, Canadian Solar provides a warranty of up to 15 years for defects in their solar panels. Warranty claims were also made easier by the government of Australia.
