Mission Solar MSE PERC 72 SX6W 415W

Performance

Power Rating 415W

The larger Mission MSE PERC 72 SX6W 415W module was once thought of as a hefty panel primarily used in larger commercial and utility applications. However, this 415W powerhouse is now being put into action on residential rooftops across Texas.

Efficiency 18.9%

Mission Solar MSE PERC 72 SX6W 415W module efficiency rating of 18.9% places it on the higher end of average solar panel efficiency. Their achievement is largely due to the 6 bus bars on their mono-PERC cells, which allow more electrons to flow through each solar cell

Power Tolerance 0/+3%

Power tolerance refers to the amount of electricity it will produce either above or below its rated power capacity at Standard Test Conditions (STC). The smaller the power tolerance deviation or range, the more accurate the rated power capacity is.

Mission Solar modules have a power tolerance of -0/+3%.

This means Mission Solar MSE PERC 72 SX6W 415W will, at the very minimum, operate at their rated capacity, However, these panels have exceeded, by as much as 3%, of its rated capacity. For example, a Mission Solar panel rated at 415 W will be able to operate anywhere from 415 W to 427 W (or 3% higher than 415) under STC

Temperature Coefficient PMax: -0.36

Solar panels perform best at 77°F (25°C). Obviously, Texas temperatures will far exceed 77°F for long portions of the year. A solar panels temperature coefficient is a measurement indicating how well a specific model of solar panel will perform outside of ideal operating conditions.

Knowing a panel’s temperature coefficient and the temperature of the panel will allow you to predict your panels performance during the dog days of summer.

Temperature coefficients are calculated in Celsius.

With each degree above 25°C (77°F) a given solar panels electric output will be diminished by its temperature coefficient.

Using the above methodology, The MSE PERC 72 panels has a temperature coefficient of -0.36%/°C. Hence, when this panels temperature increases by one degree, from 25°C to 26°C (77° F to 79° F), expect a 0.36% reduction in potential electric output.

When it's July in Texas and temperatures have climbed to 95°F (35°C) expect electric output to decrease by 3.6%. When the hottest hours of summer days drive the mercury into the triple digits – say, 113°F, the Mission Solar MSE PERC 66 and MSE PERC 72 will decrease by approximately 7.2%.
