SunPower vs Mission Solar: Whose Solar Panels are Better?

by | Oct 16, 2019 | about, Products

Making the switch to solar power brings up several questions. Is sunlight plentiful in your area? In our sunny North Texas climate, the answer is a resounding yes. We get more hours of sunlight every day than most other states. Do you have access to a highly trained and experienced solar panel installation team? Again, with Kosmos Solar serving the Dallas-Fort Worth Metroplex, that’s a yes. Which solar panels are the best? That’s a more complex question. There are many great panels to choose from, and the answer largely depends on your priorities and personal preferences.

SunPower and Mission Solar are two front-runners in the solar panel market. Each brand has a loyal customer base. To help you decide which solar panels are best for your needs, here is a quick look at their efficiency, performance, and warranties. Remember, Kosmos Solar is here to help get your panels installed correctly, whether you purchase them through us or come to us with panels already in hand.

Let’s take a look at how these two prominent brands compare.

Efficiency

Efficiency is the measure of how well a solar panel captures sunlight and turns it into usable electricity. Most solar panels have an efficiency rating between 15% and 17%. Mission Solar’s panels have an efficiency rating of 18.05% to 18.95%, depending on the model. 

SunPower’s X-Series solar panels have similar efficiency. Some reports put their energy conversion rate at 22%. The trade-off is the expense; SunPower panels are more expensive for a nominal difference in efficiency. Mission’s panels are more affordable and just as reliable.

Energy Output

This is a measure of how many watts of electricity each solar panel puts out. The more watts per panel, the fewer panels you will need to power your home – and the less money you’ll have to shell out to get them installed. SunPower’s A-Series solar panels have an output of 400 watts. Mission Solar’s MSE Perc panels follow close behind with an output of 315 watts. They have excellent long-term reliability and are fully compliant with the Buy American Act.

Warranty

All good solar panels come with a warranty of some kind. Most come with a 10-year materials warranty from the manufacturer. Mission Solar’s warranty is good for 25 years and protects the consumer against any defects in the solar panels. Not only does it cover all parts of the system (not just the panels themselves), it also covers the cost of shipping, the cost to remove and replace the defective part. This is better than the industry standard warranty for solar panels. SunPower offers a similar 25-year warranty for its products.

SunPower vs Mission Solar: The Bottom Line

When you look through all the comparisons above, it’s easy to see why Kosmos Solar prefers to work with panels from Mission Solar. We believe in giving our customers the very best service we can provide, and that starts with using the best products on the market. For the best combination of power and affordability, you can’t go wrong with solar panels from Mission Solar and an installation by the skilled team at Kosmos.
