Canadian Solar and Mission Solar are leading manufacturers of high efficiency, mid-range solar panels. Their solar modules are desirable for a variety of system types from residential to commercial, roof mount to ground mount and more. Canadian Solar, headquartered in Ontario, Canada has proven itself to be an industry leader in solar cell and module technology since its founding in 2001. While Mission Solar has quickly begun building brand recognition with their U.S. factory in San Antonio, Texas, where they design, engineer and assemble their solar modules.

Both Canadian Solar and Mission Solar offer a wide array of options in their solar panel offerings, including black on black designs, split cell technology, 60 cell, and 72 cell designs. Canadian Solar’s offerings also include bi-facial modules, bi-facial modules are recommended for ground mount applications, preferably installed on a reflective surface, to ensure that both sides of the module are getting ample sunlight in order to run more efficiently. In short, they are typically used in specific applications, if you have a site with the mentioned setup, you will want to see what Canadian Solar has to offer for you.

In terms of cost, both  Canadian Solar and Mission Solar land in a mid-range price point, coming in between $0.10 - $0.20 more expensive than value-based modules such as those that can be purchased from Longi Solar. When compared to high value modules from manufacturers such as LG and Panasonic, the modules are between $0.20 - $0.35 less expensive on average.

In this Canadian Solar vs Mission Solar Panel Comparison, we will be explore the following:

• Specifications and Technology
• Average Costs and Efficiency
• Potential ROI
• Warranty and Degradation Rate
• And Solaris Recommendations

Specifications and Technology

Canadian Solar and Mission Solar both utilize Passivated Emitter Rear Contact (PERC) cell technology , which offers higher efficiency, and lowers the risk of hot spots developing. PERC works by utilizing the bottom layer of the cells to bounce sunlight back into the solar cell, which creates a dual capture process. This process enables the cells of your solar panel to capture more of the sun’s rays and generate electricity.

Where Canadian Solar differs from Mission Solar is largely seen in the solar module cell count. Canadian Solar's new lines largely utilize half-cut cell technology, which increases module efficiency and further decreases the chances of hot spots developing. The half cut cells work in the same manner as full cut cells, so a 144 half cut panel will be compatible with 72 cell module technology and 120 half cut cell panel is compatible with 60 cell module technology. To date, Mission Solar's modules are full cell 60 and 72 monocrystalline cell configurations.

Both Canadian and Mission's solar panels have high efficiency ratings for low irradiance environments, which further enhances the overall efficiency of your solar panel system. This increased efficiency is beneficial for both intermittent and frequent low light environmental conditions. So, no mater if you life in low light/temperature or high light/temperature, PERC cell technology is specifically designed to not only operate in the field, but do so with the upmost efficiency.

The table below reflects a number of available solar panels from Canadian Solar and Mission Solar, review Average Costs and Efficiency for a quick summary for comparison.

The number of cells your solar panel has may affect the type of inverter you can use with the system. For example, most 60 cell and 120 half cell panels are compatible with the IQ7 from Enphase Energy, where as 72 and 144 half cut cell panels cannot be paired with the IQ7 and must use the IQ7PLUS. There are exceptions to this such as Canadian Solar's CS1H series which has a higher overall production rate that is not compatible with the Enphase IQ7.

For string inverter systems, the overall electrical output of your system will determine the inverter, and in some cases, the optimizer that will be best for your system. For assistance in sizing out your system and inverter, fill out our quote request form here.

Average Costs and Efficiency

In terms of price per watt averages, Canadian solar panels start at $0.68/watt, and Mission solar panels start at $0.71/watt. These price points come in around $0.05 - $0.10/watt more than value based panels from manufactures such as Longi and Trina Solar. When comparing the modules to high range panels, both Canadian Solar and Mission Solar average $0.20-$0.25/watt less expensive.

Canadian Solar's average efficiency rating is well above average, especially for a mid range panel. Their half cut cell design elevates the overall efficiency rating to rival high value panels like Panasonic and LG. Mission Solar's average efficiency is also above average when compared to other mid-range panels overall, but they fall behind Canadian Solar. This difference in efficiency may be made up in the expected degradation rate and output power of the manufacturers modules, we will cover this under Warranty and Degradation Rate.
