If you are looking for American-made panels at reasonable prices, Mission Solar panels might be the perfect option for you. They produce monocrystalline solar panels using PERC technology. In this Mission Solar panels review, we will learn about their solar products, prices, and terms of the warranty in detail.
Mission Solar Panels Review
Mission Solar Energy is an American solar panel manufacturer based in San Antonio, Texas. It is a subsidiary of OCI Solar Power, which is part of the South Korean conglomerate OCI Company Ltd.
The company uses materials and equipment from both domestic and international sources to design and assemble monocrystalline solar panels in the U.S.A. These panels are high-quality and are suitable for residential and commercial uses. Although these panels aren’t cheaper than their Chinese and Canadian counterparts the price difference is quite negligible and can be overlooked due to the superior quality.
Mission Solar Products
Mission Solar produces monocrystalline solar panels using PERC technology. PERC stands for passivated emitter rear contact, which is a technique that improves the power output and efficiency of solar cells by adding a thin layer of material on the back of the cell. They have a range of products for both residential and commercial purposes.
Mission Solar has two main product lines:
These are the following features of the MSE PERC 60/66 and 70 series panels:
- Positive power tolerance of 0/+3%, meaning they can produce up to 3% more power than their rated output
- High resistance to potential induced degradation (PID), salt mist corrosion, and ammonia corrosion
- Extreme weather resilience, withstanding up to 5,600 Pa of front load and 5,631 Pa of back load
- Compliance with the Buy American Act and the American Recovery and Reinvestment Act, making them eligible for government projects.

Mission Solar Panels Performance and Efficiency
One of the main advantages of Mission Solar panels is that these panels have been tested and certified by various independent laboratories and organizations, such as UL, IEC, TUV, and CEC. They have also been proven to perform well under real-world conditions, such as low-light, high-temperature, and harsh weather environments. In this Mission Solar review, let’s learn about the performance and efficiency of their panels.
1. Performance Influenced due to Temperature Coefficient
The performance of Mission Solar panels depends on how well they can handle heat and sunlight. The temperature coefficient is a measure of how much the panel’s electricity output changes with temperature. The lower the temperature coefficient, the better the panel can withstand high temperatures.
- MSE PERC 60/66 series has a temperature coefficient of -0.377%/°C -0.35%/°C
- MSE PERC 72 series has a temperature coefficient of -0.35%/°C.
This means that for every degree above 25° C (77° F), the panel’s output decreases by 0.377% and 0.35% for the MSE PERC 60/66 series and MSE PERC 72 series, respectively. If the panel’s temperature rises to 35° C (95° F), the output also drops by 3.77% or 3.5%, respectively. These values are comparable to the industry average, but not as good as some of the best-performing panels on the market. Therefore, Mission Solar panels are suitable for moderate to hot climates, but may not be the optimal choice for very hot regions.

2. Performance Influenced due to Degradation Rate
Another factor that affects the performance and efficiency is the degradation rate, solar panels typically lose some of their efficiency every year due to factors such as aging, weathering, and wear and tear.
Mission Solar Panels have a relatively low efficiency rate of 18%-19.5%. On the other hand, their degradation rate, which measures how much their power output declines over time, is 2% in the first year and 0.58% every year after that until year 25. This implies that Mission Solar panels will retain at least 84.08% of their initial power output even after 25 years. This is slightly higher than the industry standard of 80% but lower than some other brands that offer lower degradation rates, such as SunPower and LG.
Using this data, here is a chart for a simple understanding of the degradation rate of Mission Solar Panels.

Now, in this Mission Solar Panels review, let’s talk about their warranty.
Mission Solar Panels Warranty
Mission Solar Energy provides the customer with a Limited Product Warranty and a Limited Power Warranty for its Solar Panels. It begins on the purchase date or 12 months after the production date (shown in the serial number), whichever comes first.
- The product warranty lasts for 12 years or 25 years for modules made after August 1, 2019, and covers defects in materials and workmanship.
- The power warranty lasts for 25 years and covers power output below a certain level.
In case a Module’s power output falls below the Output Threshold, Mission Solar can choose to fix or swap out faulty Modules, give extra Modules, or pay back the gap based on the current market values.
Here are some of the terms of the Mission Solar Warranty
- The warranty does not cover changes in appearance after delivery or glass breakage from external causes.
- The warranty does not cover alterations without permission or events outside Mission Solar’s control.
- The warranty can be transferred to other owners or locations under conditions.
- The warranty also covers force majeure events and the validity of the remaining terms if any part is invalid.

Are Mission Solar Panels Good?
Mission Solar panels are good for customers who want to support an American-made product that offers durability and high quality. They are also reliable as they undergo rigorous testing and quality control. Their 25-year product and power warranty are among the best in the industry. The affordability of Mission Solar panels falls somewhere in the mid-range when compared to the other competitors in the market. To sum up this Mission Solar panels review, these panels may not be the best choice if you are seeking the highest efficiency in the market. However, their lower degradation rate makes up for it compared to the competition, such as LG or SunPower. Ultimately, buying Mission Solar panels depends on your preferences, and you should compare different options and get multiple quotes before making a final choice.
