American-made and engineered for the long haul, the Mission Solar MSX10-435HN0B delivers 435W of class-leading N-type TOPCon output with 22.3% efficiency — built in San Antonio, Texas for residential and commercial rooftops that demand the best. This pallet of 28 panels gives you 12,180W of total array capacity straight off the truck.

• 22.3% High-Efficiency N-Type TOPCon Technology – Advanced high-density interconnect design with multi-busbar cells improves current flow and reduces resistance for best-in-class power output.
• Positive Power Tolerance – Ships at 0 to +3% of rated power, guaranteeing every panel performs at or above its 435W nameplate right out of the box.
• Low Temperature Coefficient – A -0.29%/°C temperature coefficient means this panel outperforms conventional PERC modules in real-world high-heat rooftop conditions.
• Built for Tough Conditions – Tested to 5,400 Pa front load and 2,400 Pa back load per UL 61730, with corrosion and degradation resistance engineered for harsh environments.
• Best-in-Class 30-Year Production Warranty – Backed by a 25-year workmanship warranty and a 30-year power performance warranty guaranteeing 86% capacity at year 30.

Manufactured in the USA with 6.2% domestic content and certified by Intertek, CEC, and SA, this panel is built to surpass industry standards in both performance and long-term reliability. Third-party verified low-light performance means your system keeps producing even when the sun isn't cooperating.

The 3.2mm AR-coated tempered glass and Polyolefin Elastomer (POE) encapsulant protect the N-type TOPCon cells from the elements, while the 35mm black anodized aluminum frame keeps the install looking sleek on any rooftop. An IP68-rated junction box rounds out a module built to handle whatever the weather throws at it.

With a 1,500V max system voltage, Staubli MC4 connectors, and degradation guaranteed not to exceed 0.45% annually from year 2 through year 30, this full pallet of 28 is the kind of investment that keeps paying back for decades.
