Marine solar panels can generate renewable energy to power ships as well as personal gadgets while sailing, at anchor or docked. These solar panels use photovoltaic (PV) technology to charge the ship’s batteries, reducing the need to rely on fossil fuel generators or dock lines for power. By replenishing the boat’s batteries, they provide the power needed to run essentials such as bilge pumps, fish finders and echo sounders, radios, GPS devices, lights, fans, kitchen appliances, or other boat operations.Mono 210w Half Cut Cells Photovoltaic Panels
By harvesting the sun’s rays throughout the day (almost every day), offshore solar panels can help minimize the amount of fuel you need to carry to keep electronics running at full capacity. The best marine solar panels available today are designed to withstand high seas weather conditions so they can continue to power on-board electronics for years.from China Gaojing solar supplier.

In creating this guide, we looked at many types, styles, and sizes of solar panels to provide plenty of options. This list of the best marine solar panels includes some of the best options for each type of panel such as portable, flexible or rigid panels and includes a variety of sizes to suit different boating needs.
In many cases, manufacturers offer similar panels with multiple power options. For example, if solar panels are offered in 50W, 100W, and 170W sizes, we will not assign them all to the same solar panel, unless each specific wattage type is unmatched in its category.
While we focus on marine solar panels and systems, we also understand that these modules and systems are also intended for other mobile platforms such as motorhomes. As such, some of these products are sold or advertised in this way.
In total, we have evaluated over 75 professional reviews from over 60 different modules and solar systems, and reviewed thousands of customer reviews from almost 20 sites and resources. In this study, we have identified the top 20 solar panel brands for the marine environment. We use tools to ensure that customer reviews are created by real customers and select those that rank highly in both consumer and professional reviews.
While solar panels are an environmentally friendly way to generate electricity (more so than diesel or gas generators), only two companies currently have cradle-to-cradle certified panels in their arsenal. This means that consumers will have to decide what to do with their solar panels towards the end of a product’s life. This is a disadvantage of this solar solution (although most solar panels have a relatively long lifespan). We also checked to see if there were any specific solar products that we included in this list, any Cradle to Cradle certifications, but unfortunately there were none.
The maintainability of a product is critical to its overall longevity, so warranty and customer service is another important consideration. Whenever possible, we choose panels from North American companies because we know that many solar panels and their components are still manufactured overseas.
Why it’s included: Renogy’s 100-watt monocrystalline solar panel is one of the best options for most boaters’ needs. It is powerful and compact, making it ideal for boats of almost any size.
Specifications: – Dimensions: 42″ L x 21″ W x 1.4″ H – Weight: 14.1 lbs – Claimed efficiency: 22.3% – Battery type: Mono – Connectors: MC4
Cons: – Only solar panels, no mounting hardware – Slow customer service – No end-of-life recycling program
If you are just looking for one solar panel for your boat and already have the other equipment you need to connect to your power system (such as solar controllers and hardware), then the Renogy 100W monocrystalline solar panel is our answer. Darling. It is compact and can consume up to 500 watt-hours per day. In addition, the company rates the panel’s battery efficiency at an impressive 22 percent.
Renogy’s solar panels have bypass diodes so that each cell can transfer as much power as possible to the battery and charge controller. The solar panel is suitable for marine use and comes with an IP65 waterproof junction box and an IP67 waterproof solar connector. Pre-drilled for easy installation and compatible with Renogy mounting hardware (sold separately).
Made in Thailand, this panel is backed by a 5-year limited workmanship warranty and a 25-year product warranty (80%). Renogy offers many social initiatives, such as donating power plants to those affected by natural disasters, and the company is also involved in educational partnerships to develop solar energy projects and sustainable development.
Reason for choosing: If Renogy 100W monocrystalline solar panels are out of stock, HQST 100W 12V monocrystalline solar panels are a good choice. HQST panels have similar features, connections and good reviews.
Specifications: – Dimensions: 40″ L x 20″ W x 1.2″ H – Weight: 12.8 lbs – Efficiency: 22.3% – Battery Type: Mono – Connectors: MC4
Cons: – Solar panels only, no mounting hardware – Fewer mounting options than Renogy – Weaker frame
The HQST 100W 12V Monocrystalline Solar Panel looks and performs almost exactly like the Renogy 100W Monocrystalline Solar Panel, only at a slightly lower price. In fact, some suspect that this panel may just be a renamed version of the Renogy panel (something that happens with imported modules).
However, while HQST has the same high rating as Renogy solar panels, it has fewer overall ratings and customer reviews. Its panels come with a 25-year power output guarantee, which ensures that after 25 years of use, they will produce 80% of their rated efficiency. The panels are made in China and can be purchased individually or in packs of two or four.
Like Renogy, HQST has a block bypass feature that allows each block to run at its best performance even when parts of the panel are shaded. It also has an IP65 rated junction box, which means that it is quite water resistant and can withstand a jet of water for at least 15 minutes, which is an important protection against small or ocean waves when the boat is sailing.
Reason for choice: SunPower 100W monocrystalline flexible panels are ideal for small boats and curved surfaces.
Specifications: – Dimensions: 46″ L x 22″ W x 0.8″ H – Weight: 4 lbs – Claimed efficiency: 22% to 25% cells – Element type: Monocrystalline – Connectors: MC4
Advantages: – Light weight – Highly waterproof (IP67) connector and junction box – Slim and flexible – Cradle to Cradle certified company
SunPower makes some of the most efficient commercial solar panels, and the company’s line of flexible solar panels is no less impressive. In fact, several other manufacturers use Sunpower photovoltaic cells for their own panels (even if the products are not branded as Sunpower). It is also one of only two major solar companies to be Cradle-to-Cradle certified, which means it has a plan to recycle components at the end of their life cycle.
These semi-flexible panels are great for curved boat surfaces or where the solar panels are attached to something more flexible like biminis or covers. The plastic coating on these panels makes them highly impact and weight resistant (in case you accidentally step on them while rocking).
Flexible solar panels typically have thinner layers of photovoltaic material than rigid solar panels, and most solar panels are less efficient than monocrystalline (or even polycrystalline) rigid panels. However, SunPower still claims that their Maxeon solar cells can deliver up to 25% efficiency in flexible panels. We chose the 100 watt panel because it is most commonly used in boat applications, but the SunPower is also available in larger or smaller sizes.
All SunPower flexible panels use the same type of MC4 connector (cable adapter) and have an IP67 rated junction box, making them more waterproof than the competition.
Why it’s recommended: If you prefer polycrystalline solar panels (slightly cheaper, but larger), Newpowa’s 100W polycrystalline solar panel is perfect.
Specifications: – Dimensions: 36″ L x 27″ W x 1″ H – Weight: 15.4 lbs – Claimed efficiency: 22.9% – Battery type: polysilicon – Connectors: MC4
Newpowa’s 100W polycrystalline solar panels are slightly squarer and larger than monocrystalline panels of the same wattage, but cost slightly less than monocrystalline panels. The squareness of the panels can also be used for specific purposes or boat surface area. The solar panels have diode bypasses to help each cell generate the maximum power possible in partial shade (avoiding shaded cells) and have IP67 connectors and IP65 rated junction boxes.
While some are concerned that polycrystalline solar panels are slightly less efficient than monocrystalline solar panels, this simply means that more space is needed to produce the same amount of electricity. Therefore, polycrystalline solar panels should be considered for large boats or boats with a very flat surface.
The panel includes a two-year limited warranty on materials and workmanship, as well as a 10-year product warranty (90%) and a 25-year product warranty (80%).
Why it’s recommended: If you need all the hardware and accessories to connect your solar panels to your boat’s batteries, the Renogy 100W Monocrystalline Solar Panel Kit is the perfect choice.
Specifications: – Dimensions: 42″ L x 21″ W x 1.4″ H – Weight: 16.5 lbs – Claimed efficiency: 22.3% – Cell Type: Mono – Connectors: Solar Panel: MC4, Cell: Eyelet
Benefits: – Complete solar panel kit with controller and mounting hardware – Excellent value for money – Compact size – High efficiency – Multiple current controller options available
Buying just one solar panel is a good deal, but if you need all the hardware and equipment to properly connect a solar panel to a battery, check out the Renogy 100W Monocrystalline Solar Panel Starter Kit. This kit includes the same Renogy solar panels as our top pick, but includes everything else you need. The included Z-bracket mount allows the panel to be flush with the surface of the boat.
To help regulate power flow and prevent battery overcharging, you can keep your system cost below $200 by choosing a 10-amp Pulse Width Modulation (PWM) controller with this kit. Alternatively, you can upgrade the kit to include a more advanced or more powerful amplifier controller, such as a maximum power point tracker (solar MPPT controller), which is 30% more efficient than standard PWM devices. This means that controllers with a more powerful booster can charge batteries faster and connect multiple panels to the system (but they cost more). These controllers can also be connected to different battery types and voltages.
Why it’s on the list: The 100-watt DOKIO Solar suitcase is ideal for boaters who want to carry solar power with them while on the boat. This is a lightweight folio case with a built in charge controller so it can be used for any outdoor adventure.
Specifications: – Dimensions: folded: 24″L x 21″W x 2.8″H – Weight: 18.5 lbs – Declared efficiency: N/A – Battery type: Mono – Connectors: Battery: Alligator clips
Pros: – Portable lightweight single crystal panel – Sturdy anodized aluminum frame – All-in-one kit
Cons: – The stand could be more adjustable and sturdy – Can’t connect multiple devices – A bit expensive
The 100W DOKIO Solar Panel Foldable Carrying Case is ideal for users who require a powerful and portable solar solution. The all-in-one includes a charge controller and a USB port for direct charging of small devices. It also includes alligator clips for connecting an 18-volt battery.
Dokio, founded in 2007, is an ISO 9001 certified solar powered portable suitcase company based in China. The great thing about this set is that it is not only for boats, you can also use it for car camping, glamping and RV. So it’s a very practical solution, perfect for users with a lot of adventure gear.
Unfortunately, the stand is not strong enough to be used on a boat in bad weather conditions. However, because it is foldable and only weighs about 20 pounds, you can quickly break it down and store it in harsh environments. It’s also easy to go ashore to power devices such as laptops or USB speakers during daytime sailing breaks.
Why it’s recommended: This versatile multi-panel kit delivers superior electronics without having to buy a single-point panel.
Specifications: – Dimensions: Four Panels: 42″L x 21″W x 1.4″ – Weight: 72.8 lbs – Claimed Efficiency: 22.3% – Cell Type: Mono – Connectors: Solar Panel: MC4, Cell : eyelet
Benefits: – Complete solar panel kit with controller and mounting hardware – High efficiency – Multiple current controller options available
This Renogy 400 Watt Solar Starter Kit is ideal for large boats or yachts, and safari safari crews who plan to use the sun to power minimal electronics and devices such as microwave ovens, small refrigerators and laptops. It is equipped with four 100-watt Renogy solar panels, as well as all the equipment to install it and the equipment to connect to the boat’s batteries.
This four rigid panel kit requires more installation space than a single panel system, so it is not suitable for smaller boats. However, if you have a large boat with plenty of deck space, this can eliminate the need for the boat’s motor to charge the battery and quickly recoup the initial cost of the system using free solar energy.
