The Mission Solar N-Type Bifacial 132HC series comprises bifacial modules designed to maximize energy yield in every square meter. A key advantage is the combination of N-type and TOPCon cell technology with a half-cut architecture, which ensures stable operation even at high temperatures and under varying solar conditions. Thanks to dual-glass construction, the panels are better resistant to environmental stresses and long-term use, while also allowing for real gains from light reflection from the ground - particularly on bright roofs, in ground-mounted systems, and on carports. The series also features low degradation over time, which simplifies energy production forecasting and reduces project financial risk. This makes it a good choice for C&I and PV farm investors who expect certainty in parameters and high repeatability in supply, rather than just high power from a catalog.

What owners get
US-based manufacturing (San Antonio, TX)

Mission Solar has assembled modules at its own Texas facility since 2014, which is relevant for qualifying for IRA domestic content bonus credits and reduces exposure to import tariffs and supply-chain risks typical of Asia-based manufacturers.

N-type TOPCon with half-cut cells

132 half-cut N-type TOPCon cells deliver a lower LID/LeTID degradation rate and better high-temperature performance than older PERC technology, translating into higher realized annual yield, especially in summer conditions.

Dual-glass bifacial construction

The dual-glass design improves mechanical and chemical resistance to environmental stress and enables real energy gains from ground-reflected light - an attractive option for PV farms, carports and bright flat roofs.

30-year linear power warranty

The manufacturer offers a uniform 30-year linear power warranty across the entire series (610-620 Wp), matching or exceeding the typical 25-30 years offered by competitors and simplifying LCOE modeling for C&I projects.

Specs on par with segment leaders

610-620 Wp power and 22.6-23% efficiency put the series in line with top peer comparables - HT-SAAE HT66-18X(ND)-F (620 Wp, 23%) and Weran Solar LR7-72HTH (620 Wp, 23%) - showing no gap versus the best offerings currently on the market.

Trade-offs
No Tier-1 (bankability) status

The manufacturer is not listed as tier-1 bankable, which can limit access to project financing requiring BNEF Tier 1-listed modules - a meaningful constraint for large-scale C&I investments and debt-financed PV farms.

Short track record for the series

The N-Type Bifacial 132HC series only debuted at RE+ 2025, so multi-year field data confirming the claimed low degradation and dual-glass durability under real operating conditions is not yet available.

Common questions

6 answered
What is the power output warranty on Mission Solar N-Type Bifacial 132HC panels?
The Mission Solar N-Type Bifacial 132HC series comes with a 30-year linear power output warranty. Thanks to the N-type TOPCon cell technology, annual degradation is lower than in conventional PERC modules, resulting in higher real-world energy yield over the system's lifetime and more predictable financial returns for project owners.
Are Mission Solar 132HC panels bifacial and what does that mean in practice?
Yes, the 132HC series features a bifacial design with a dual-glass construction. The rear side of the module captures light reflected from the ground, rooftop surface, or surrounding structures, delivering a real-world energy gain of several to over ten percent. The effect is most pronounced on light-colored or white surfaces, ground-mount systems, and carport installations.
What is the peak power of the Mission Solar N-Type Bifacial 132HC and is 620 Wp a verified figure?
The module is rated at 620 Wp under STC conditions. This is achieved by combining 132 N-type half-cut cells with TOPCon technology. Unlike many Asian-market suppliers, Mission Solar manufactures its panels at its facility in San Antonio, Texas (USA), ensuring tight quality control and consistent module-to-module power tolerance.
Is Mission Solar a Tier 1 manufacturer and should that affect my purchasing decision?
Mission Solar is not currently listed as a Bloomberg NEF Tier 1 manufacturer. However, it is an established American PV producer with a San Antonio, Texas factory operating since 2014. Modules are UL 61730 certified and meet all standards required in the US market. For many C&I buyers, supply consistency and local warranty support matter more than the Tier 1 label itself.
How do Mission Solar N-Type 132HC panels perform during hot summer days?
N-type TOPCon cells have a lower temperature coefficient of power than PERC cells, which means less power loss on hot days. The half-cut architecture (132 cells) further reduces resistive losses under high irradiance, helping the system maintain more stable output during peak summer hours compared to conventional full-cell PERC modules.
Are Mission Solar N-Type Bifacial 132HC panels suited for C&I and utility-scale PV farms, or only residential rooftops?
The 132HC series is primarily aimed at commercial and industrial (C&I) investors and utility-scale PV farms, where the high 620 Wp module power, low long-term degradation, and bifacial energy gains make the most financial sense. The module's size and weight make it less practical for small residential rooftops but an excellent fit for ground-mount systems, carports, and large industrial rooftops.
