100 Watt Carbon Fiber Marine Solar Panel With SeaDog Rail Mount Brackets – DIY Install
The 100 Watt Carbon Fiber Marine Solar Panel with SeaDog Rail Mount Brackets is a rugged, high-performance power solution designed specifically for sailboats and marine rail systems. This version is offered as a DIY setup, giving customers greater control over the installation process.
This package includes the solar panel and one pair of genuine SeaDog rail-mount brackets. The brackets are designed to be mounted to the back of the panel by the customer as part of a simple DIY installation process.
Once installed, the SeaDog brackets clip directly onto standard 1” boat rails and can be adjusted by hand to face the sun or folded flat when docking or not in use.
The solar panel features a carbon fiber reinforced backing, offering a rare balance of flexibility and strength. It has slight “give” while remaining extremely stiff and durable, , capable of handling heavy marine use and vibration.
It uses A+ Grade SunPower solar cells with 24.4% efficiency for maximum energy output. The advanced split-panel design allows one half to continue producing power even when the other half is shaded. The cells themselves are also shade tolerant, so partial shading does not stop production.
The surface is protected with a premium ETFE laminate that resists cracking and will not turn milky over time, even under intense UV and saltwater exposure. This is a marine-built solar solution designed for real-world offshore use, combining efficiency, durability, and simple hands-on adjustability.
✅ Each cell works when partially shaded unlike most other solar cells where the whole panel will go down if a portion of a cell is shaded.
✅ A+ grade Sunpower Maxeon cells produce relatively high amounts of power even at low sun angles, thus generating more watt-hours over the course of a day than lower quality panels.

After purchase, we will provide a recommended list of items needed as a kit on Amazon to complete the installation.
For convenience, you may purchase the following recommended items separately from Amazon to complete the installation. These items are not included and are purchased directly by the customer.
Recommended Installation Items (Purchased Separately):
🔹 3M VHB Waterproof Mounting Tape
🔹 3M Primer 94
🔹 Isoprophyl Alcohol
🔹 3M 5200 Marine Adhesive Sealant or another sealant is a good idea all around the edges (to apply additional holding power)
Why Primer is Needed
ETFE (ethylene tetrafluoroethylene) (the solar panel backing material) is a low-surface-energy fluoropolymer, so it can be tricky for adhesives like 3M VHB tape to bond reliably without help. While many people successfully mount flexible ETFE-backed solar panels using VHB tape (especially 5952 or 4952 series) after thorough cleaning, a primer is strongly recommended for maximum strength, longevity, and to avoid peeling over time—particularly in outdoor/exposed conditions with temperature swings, UV, and vibration.
Recommended Primer
3M Tape Primer 94 (also called 3M Primer 94) is the best choice for ETFE and most low-surface-energy plastics.
- It's specifically formulated for difficult substrates like polyethylene, polypropylene, fluoropolymers, and other low-energy plastics.
- It creates a better bonding surface and helps block any additives or oils that could migrate and weaken the bond.
- Widely used in solar, RV, marine, and sign applications where VHB is applied to ETFE or similar films.
3M Adhesion Promoter 111 (AP111) is a good alternative, but it's better suited for high-surface-energy materials (metals, painted surfaces). It works on some plastics, but Primer 94 is the preferred option for ETFE-like surfaces.
How to Apply the Primer and Tape
- Clean both the ETFE panel back and the aluminum bracket base with 50/50 isopropyl alcohol/water (or 3M VHB Cleaner) and a lint-free cloth. Let dry completely.
- Apply a very thin, even coat of Primer 94 to the ETFE surface (and optionally to the bracket if needed). Use the pen/ampule applicator for control—don't over-apply, as excess can reduce bond strength.
- Let the primer dry for 30–90 seconds (it should feel tacky but not wet).
- Apply your VHB tape to the bracket, remove the liner, press firmly onto the primed ETFE surface, and apply strong pressure (ideally 15 psi for 10–20 seconds) or use a roller.
- Full bond strength builds over 24–72 hours.
Quick Tips for Best Results
✅ Always test on a small, inconspicuous area of your panel first.
✅ If you're using a thicker VHB like 5952, it already bonds well to low-energy surfaces, but Primer 94 still gives the most reliable long-term results.
✅ For critical/high-wind applications, combine the primer with edge sealing (Sikaflex 521 UV or similar) to prevent water intrusion.
⚠️ If you skip the primer and the bond fails later, the tape is extremely hard to remove from ETFE without damaging the panel—so using Primer 94 is cheap insurance for a permanent hold.

Frequently Asked Questions (FAQ)
Does this panel fit standard boat rails?
Yes. The included SeaDog rail-mount brackets are designed to fit standard 1” marine rails once installed by the customer.
Are the SeaDog brackets pre-installed on the panel?
No. This product includes the solar panel and a pair of genuine SeaDog rail-mount brackets. The brackets are installed by the customer as part of a simple DIY installation.
Can I adjust the panel’s angle once installed?
Yes. After installation, the panel can be tilted toward the sun or laid flat against the rail for docking or low-clearance situations.
Will I need additional items to complete the installation?
Yes. After purchase, we will provide a recommended list of items needed as a kit on Amazon to complete the installation.
Is this panel strong enough for harsh marine environments?
Absolutely. The carbon fiber reinforced backing and ETFE laminate are designed to withstand vibration, salt spray, UV exposure, and heavy marine use.
Does the ETFE coating turn cloudy over time?
No. ETFE is highly resistant to cracking, clouding, and yellowing unlike PET-based panels.
Is this panel waterproof?
Yes. The panel is fully marine-rated and designed for exposed outdoor use.
Do I need to drill holes to install it?
No. The rail clamps allow secure mounting without drilling into your boat.
What is the difference between the SeaDog bracket version and the sliding aluminum bracket version?
The SeaDog bracket version is permanently pre-installed and allows the panel to rotate and tilt only, making it quick and simple to aim toward the sun. The sliding aluminum bracket version allows the brackets to slide back and forth along the panel, giving more flexibility in matching rail spacing and custom mounting positions.
