To help narrow down the ideal manufacturer for your boat, tell me:

• Where do you plan to mount them (e.g., bimini canvas, hard deck, or coachroof)?
• Do you need a walkable surface (do people step on them)?
• Roughly how many watts of power are you looking to generate?

Yes. If you’re looking for a manufacturer rather than simply a retail brand, I’d start with these:

• Solbian — Probably my first choice for a serious marine/OEM project. They manufacture in Italy and specifically engineer lightweight flexible panels for boats, catamarans and yachts. Their panels are designed for salt, wind and temperature exposure, and they offer custom shapes, dimensions, voltages and connection layouts for OEMs. Their SP series uses high-efficiency Maxeon back-contact cells.
• Sungold Solar — A good option if you need OEM/ODM manufacturing at larger volumes and are more cost-sensitive. Its TF series is specifically marketed for marine applications, with ETFE construction, salt/moisture resistance and customization of size, voltage, cable layout and installation.
• Sola-E — Specializes in flexible/portable solar manufacturing and has a dedicated marine series. Its UT waterproof series uses one-piece ETFE lamination and is IP67-rated; it offers 100–200 W configurations. The company is based in Shenzhen, China.
• Couleenergy — Worth investigating if you need custom dimensions or relatively low OEM quantities. Its marine-oriented ETFE modules range from 30–300 W, with custom dimensions, wattage, voltage, connectors and cell technology; it states an OEM MOQ of 100 units.

My recommendation

If this is for a commercial marine product, yacht/boat builder, or OEM program, I'd shortlist Solbian, Sungold and Sola-E and ask each for:

1. Custom panel dimensions and CAD drawings
2. Minimum bend radius
3. ETFE vs. other encapsulation
4. Salt-spray/corrosion test results
5. Waterproofing/IP rating of the complete module and junction box
6. UV and thermal-cycle test data
7. Walk-on/deck loading capability, if applicable
8. Shading performance — particularly important around masts, rigging and hardware
9. Cell technology and efficiency
10. MOQ, tooling/NRE charges and sample pricing
11. Warranty and expected marine service life
12. UL/IEC certifications relevant to your target market

For a high-end marine application where reliability and power density matter more than lowest price, Solbian stands out. Their current materials specifically emphasize marine use and custom OEM manufacturing rather than simply adapting an RV panel for a boat.

If you tell me (a) required wattage, (b) panel dimensions/shape, (c) whether it will be walked on, (d) expected annual quantity, and (e) where you want it manufactured, I can narrow this to 3–5 manufacturers and compare their MOQ, technology, certifications, estimated pricing, and contact information.

Several prominent manufacturers specialize in or offer high-end flexible and semi-flexible solar panels engineered specifically to withstand harsh marine environments (saltwater exposure, high UV, humidity, and deck foot traffic).

If you can share the available dimensions on your deck or bimini , your target power output (watts) , and whether you need them to be walkable , I can help you narrow down the ideal manufacturer and kit.

Yes. If you are looking for a manufacturer rather than simply a retail seller, I’d shortlist these:

My top three

1. Solbian — best if marine durability is the priority.
They have been developing semi-flexible panels specifically for marine environments since 2007. Their panels can be walkable when properly installed, can be sewn through for canvas applications, and some models are available in custom shapes and sizes.

2. Sungold — best for an OEM/private-label program.
They explicitly offer custom voltage, wattage, dimensions, connectors, logos and packaging, and have a marine-grade line designed for salt air and moisture.

3. Sola-E — interesting if you need a purpose-built marine module.
Their UT series is specifically described as a marine/deck product: one-piece ETFE laminate, IP67, and designed for salt-spray/wet environments. They also offer engineering/test data for vibration and thermal cycling.

If you're sourcing these for your own product

I'd specify ETFE rather than PET, and ask the manufacturer for:

• Salt-mist/corrosion testing
• IP rating of the complete module, not just the junction box
• UV/thermal-cycle testing
• Vibration and fatigue testing
• Minimum bend radius
• Walk-on/impact rating if they will be installed on a deck
• Delamination testing
• EL images before/after environmental testing
• Cell/bypass-diode configuration for partial shading from masts, booms and rigging
• Custom dimensions and cable-exit locations
• Warranty specifically covering marine installation
• MOQ and prototype pricing

For example, Couleenergy currently advertises custom ETFE marine panels from 30–300 W, prototypes of 1–2 units, and OEM production from 100 units, which could be useful if you're developing a new product rather than buying a few panels.

If you tell me the approximate panel size, wattage, quantity/MOQ, whether it needs to be walkable, and whether you're looking for a U.S. or overseas factory, I can narrow this down to 3–5 manufacturers that are the best fit and compare their OEM capabilities, certifications, MOQ, and estimated pricing.

When searching for flexible solar panels tailored specifically for marine environments , you want brands that use high-grade anti-UV ETFE top sheets (rather than cheap PET plastic that yellows and cracks) and premium solar cells (such as SunPower Maxeon back-contact cells Go to product viewer dialog for this item.) to withstand salt spray, foot traffic, and constant motion.

Top manufacturers and specialized suppliers focusing on marine-grade flexible and semi-flexible solar panels include:

• Solbian — Widely regarded as a premier choice for offshore sailors and marine integrators. They specialize in high-efficiency, highly durable semi-flexible panels using SunPower cells and advanced texturing to handle low-angle light and shading.
• Custom Marine Products (CMP) — Specializes heavily in marine power setups, offering high-efficiency A+ grade SunPower flexible and shade-tolerant panels split into independent diode-isolated quadrants to combat mast and boom shading.

• Rich Solar — Offers durable, highly bendable "PRO FLEX" series panels featuring IP68 waterproof ratings and robust busbar technology suited for rough weather and marine decks.

To help narrow down the best manufacturer for your specific layout, let me know:

• Where do you plan to mount the panels? (e.g., canvas bimini top, hard nonskid deck, coachroof)
• What is your target wattage or daily power consumption?
• Are you dealing with persistent shading from a mast, boom, or rigging?

Yes. If you mean a manufacturer/OEM rather than simply a retailer, I’d put these near the top of the list:

My first choice depends on what you're doing

If you're developing your own marine product and need a factory: I'd start with Sungold Solar or Couleenergy. Both explicitly support OEM/custom production. Sungold has a particularly strong marine-oriented product line.

If you need a high-end panel for an actual boat: Solbian is probably the most interesting manufacturer to investigate. Its SP series reaches up to 25.9% cell efficiency and was specifically engineered for demanding marine/mobile applications.

If you want a U.S.-oriented marine supplier: Custom Marine Products is worth contacting. They specify their panels for boats, yachts, fishing vessels, ferries, etc., and offer custom sizes/configurations.

Important specifications to ask manufacturers about

For marine use, I would specifically request:

• ETFE front surface, rather than inexpensive PET
• Saltwater/salt-mist testing
• UV and accelerated-aging testing
• Delamination resistance
• IP rating of junction boxes/connectors
• Maximum permissible curvature/bend radius
• Walk-on capability, if mounting on a deck
• Bypass-diode configuration and partial-shading performance
• Cell technology: IBC/Maxeon, TOPCon, HJT, etc.
• Custom dimensions and electrical configuration
• Minimum order quantity and tooling charges
• Warranty specifically covering marine/saltwater exposure
• IEC certification/test reports
• Samples before committing to production

One particularly important distinction: “flexible” can mean anything from a panel that bends a few degrees to an extremely flexible thin-film panel. For a boat, the mechanical requirements of your mounting surface matter enormously.

If you tell me (1) the approximate panel dimensions, (2) desired wattage, (3) quantity/year, and (4) whether you need a custom/OEM panel or an existing product, I can narrow this down to 3–5 actual manufacturers and compare their specifications, MOQ, location, and OEM capabilities.
