SpecialtyMission Solar
Made in Texas — American manufacturing with solid performance
Mission Solar is one of the only solar panel manufacturers that produces panels entirely in the United States, at their San Antonio, Texas facility. The MSE410SX6T delivers 410W with Mono PERC technology and a 25-year warranty. While not a technology leader, Mission Solar appeals to homeowners who prioritize domestic manufacturing and want to support American jobs in the solar industry.

The Mission Solar MSE410SX6T 410W delivers 21% efficiency with Mono PERC cell technology, backed by a 25-year product warranty and 85% guaranteed output at year 25. As a specialty panel, it serves a specific use case where its unique characteristics — Mono PERC technology manufactured in San Antonio, Texas, USA — provide clear advantages over standard options. NuWatt installs this panel for homeowners whose projects specifically benefit from its strengths.

The Mission Solar MSE410SX6T 410W carries a temperature coefficient of -0.35%/°C. In practical terms, this means that for every degree Celsius above 25°C (77°F) — the standard test condition temperature — the panel loses 0.35% of its rated output. On a 95°F summer day in Massachusetts, with roof surface temperatures reaching 60°C, a panel's output drops by approximately 12.3%. A lower (less negative) temperature coefficient is better. At -0.35%/°C, the Mission Solar MSE410SX6T is in line with standard Mono PERC panels. For hot climates, panels with HJT or N-type TOPCon cells offer better heat tolerance.
The Mission Solar MSE410SX6T 410W uses 108 half-cut cells, which improves shade tolerance compared to traditional full-cell designs. When a shadow falls across part of the panel, half-cut cell architecture limits the impact to only the affected string of cells, allowing the unshaded portions to continue producing near full power. This matters for rooftops with intermittent shading from trees, chimneys, vents, or neighboring structures.
A 20-panel system (8.2 kW) using Mission Solar MSE410SX6T 410W panels in Massachusetts produces approximately 10,250 kWh/year. That is roughly 854 kWh per month — enough to offset the electricity usage of many New England homes. Actual production varies based on roof orientation, tilt angle, shading, and local weather patterns.
Over the 25-year performance warranty period, the Mission Solar MSE410SX6T 410W guarantees at least 98% output in year one, degrading linearly to 85% by year 25. The annual degradation rate works out to approximately 0.54% per year — a figure that directly affects your lifetime energy production and savings. This is a standard degradation rate for the panel's technology tier.
Comparing the Mission Solar MSE410SX6T degradation curve against similar panels in our lineup.
Guaranteed minimum output over 25 years
The Mission Solar MSE410SX6T 410W includes a 25-year product warranty covering manufacturing defects, material failures, and workmanship issues, plus a 25-year performance warranty guaranteeing minimum output levels over time. The product warranty protects you if the panel physically fails; the performance warranty ensures it keeps producing electricity at guaranteed levels.
The degradation curve above shows the guaranteed minimum output over 25 years. Starting at 98% in year one and declining to 85% by year 25, the Mission Solar MSE410SX6T trails the comparison panels shown. In real-world conditions, panels often exceed their warranty guarantees — the numbers shown represent the manufacturer's guaranteed minimum, not expected average performance.
When evaluating warranty strength, consider the manufacturer's financial stability. A 25 or 30-year warranty is only as good as the company backing it. Mission Solar maintains manufacturing operations with a track record in the solar industry, though buyers should consider company size relative to larger manufacturers.

The Mission Solar MSE410SX6T 410W has a price adder of +$0.05/W compared to our base panel option. For a standard 20-panel system, this translates to approximately $410 more than the base panel option.
System pricing varies by state due to permitting costs, labor markets, and local regulations. Use the calculator above to estimate costs for your specific location. All prices shown are pre-rebate — state incentives and utility programs may further reduce your out-of-pocket cost. Note that the federal residential solar tax credit (Section 25D) expired on December 31, 2025, and is no longer available to homeowners purchasing solar systems.
The Mission Solar MSE410SX6T occupies a specialty niche where its unique characteristics provide advantages that standard panels cannot match. The cost premium is justified when the project specifically benefits from what this panel offers — whether that is domestic manufacturing compliance, bifacial energy gain, or a specific form factor.
“Mission Solar panels install like any standard residential module. Frame dimensions are close to the QCells Q.PEAK DUO. The quality is consistent and our crews haven't encountered issues with these panels. We primarily offer Mission Solar to customers who specifically request American-made panels and are willing to pay a slight premium over QCells for the Texas manufacturing origin.”

Common questions about the Mission Solar MSE410SX6T 410W, answered by NuWatt's NABCEP-certified team.
Mission Solar panels are manufactured at their facility in San Antonio, Texas. They are one of the few solar panel companies that produce panels entirely within the United States, from cell assembly to final module fabrication.
Both offer 410W Mono PERC panels. QCells Q.PEAK DUO is slightly more efficient (21.1% vs 21.0%), has a marginally better year-25 guarantee (86% vs 85%), and costs slightly less per watt. Mission Solar's key advantage is 100% Texas manufacturing — QCells manufactures in Georgia. Both are excellent Made-in-USA options.
Yes, Mission Solar is a reputable American solar manufacturer. They've been producing panels in Texas since 2014 and supply residential, commercial, and utility-scale projects. Their panels meet all UL and IEC certification standards and carry a 25-year warranty.
Yes. Mission Solar panels are manufactured in San Antonio, Texas and meet Buy American Act requirements. This makes them eligible for federal, state, and municipal projects that require domestic manufacturing compliance.
Mission Solar provides a 25-year product warranty covering manufacturing defects and a 25-year performance warranty guaranteeing at least 85% output at year 25 (98% at year 1). This is a standard-length warranty, though the degradation guarantee is slightly below QCells' 86%.
