Why is it Our Top Pick ?

Sophisticated, durable, convenient and efficient are some of the words that describe Renogy PV Solar Panel.

While our entire review is based on the best marine solar panels that would keep you longer on water, our top pick would keep you the longest.

You can not only charge your 12V batteries, but also set up Renogy PV to light up a great portion of your boat.

This means you can officially stop worrying about gas, or battery drains and set your mind free to enjoy your time on water.

  • Get the highest power from a small fortune - 2 pieces of Renogy PV with a maximum wattage of 100 each, can be used to charge deep cycle RV batteries easily. It costs a small fortune, but it’s not even closer to what you get to save.
  • Bad weather, but still wanna hit the waters? No problem, Renogy PV would give you enough power even if the clouds decide to snatch the sun away! What’s more, it can also stand high wind (2400 Pa) and snow loads (5400 Pa).
  • Want a panel to last nearly for a lifetime? Then this solar panel should be your choice. An efficiency breakdown of 95% for the first five years, 90% for the next 5 years and 80% up to 25 years - yes, it’s totally cool.
  • Sick of worrying about gas? Then put an end to your worries by using 2 pieces of these panels. Would help you light up your whole boat, keep your fish fresh in the deep freezer, and simply enjoy.


Made up of advanced encapsulation material with multi-layered sheet laminations, Renogy PV promises the highest efficiency and longest life.

Even though each panel has a capacity of 100W, if the optimum sunshine falls on it, the wattage may exceed 120W. Which also means that 100W on a normal sunny day is an easy record.

The maximum system voltage is 600V while the optimum operating Voltage and current are at 18.9V and 5.29A respectively.

Easy to move around as well because each panel weighs up to 16.5 pounds. It can also fit in to a space as small as 47 x 1.4 x 21.3 inches.


The aluminium frame of the panel is strong enough to resist corrosion, and thus ensures a very long life. To be more specific, it would last for nearly 25 years and still work at 80% of its initial efficiency.

Another significant feature is that, though this is a solar panel, it can still function when the sun is not-so-bright. Nope, it’s not magic, the bypass diodes do that.

If you already have another Renogy panel, then fixing it up with Renogy PV is a breeze as this package comes with MC4 connectors.

Together you can multiply the electricity supply and light up an additional bulb or watch an additional hour of television while you cruise off your favourite water body.

Mounting the panel on your boat should be the least of your worries as well, for it has pre-drilled holes at the back. In the meantime, if you have any question with regards to the panel, contact customer support. They are waiting for your call.


Even though the panel may last for a quarter of a century, the warranty lasts only for 5 years. Within this period, if you encounter material and manufacturer’s defects, you can claim on your warranty.

The Bottom Line

Let’s face it, Renogy 2 piece 100W PV solar panels are more expensive than our other picks. But remember that this is an investment worth for decades.

They are extremely efficient and made up of high quality material which would give you hardly any trouble.

Also remember that the power capacity is very high and sometimes could exceed what’s being advertised! All in all, there won’t be a better bang for your buck cause Renogy PV is simply amazing

 Best Budget Pick 

Sunforce 50022 5-Watt Solar Battery Trickle Charger

Rating : 4.5/5

As the name itself suggests, if you’re looking for an inexpensive solar panel that both charges and trickle charges your 12V batteries, then Sunforce 50022 5-Watt would fit in perfectly.

Small wattage, yet fast paced and you can have your batteries ever-ready to meet your unexpected journeys on water.


Though the maximum power output is 5 Watts at 333 milliamperes, for the price, it is quite handy. It weighs just 2.5 pounds and measures 14″ x 0.75″ x 13″ (WxHxD) - which makes it easily portable.

The amorphous solar cells and quite recently added Aluminium frame ensures durability and stability while its weatherproof nature gives you no reason to worry if the wind gets tough or the rain pours down.


Once you have the panel installed on your boat, with the 12V DC plug, Battery clamps, Mounting hardware that come as a part of the package, you can just forget about the panel - it will charge your batteries on its own and needs no maintenance. It would also work on gloomy days - which means you seem to get more than what you pay for!

Then there is this built in feature of overcharge and discharge protection that protects your battery from overcharging and damage. It also puts away the expense of buying yourself a regulator.

Though this is advertised as weatherproof, there have been complains about fractures due to long term exposure to the sun. Just to be on the safe side, avoid placing the panel right under the direct sunlight during mid summer.


The warranty lasts for 5 years. However, only the warranty for power output lasts for 5 years whereas the manufacturer’s and material defects are covered by a warranty of 1 year.

The Bottom Line

Though Sunforce 50022 creates only 5 Watts, it is more than enough to charge and trickle charge your 12V batteries.

You can leave them on your boat or anywhere else for that matter, and come back to enjoy ready to action batteries that would promise you some long, jolly hours on any water body.

We won’t hesitate to recommend this solar panel to you.

Top Marine Solar Panels 

If you’re on a budget, then buying Renogy 2 piece 100W PV solar panels may seem far fetched.

That is basically why we have some back-up models lined up just for you.

They may not have everything you want, but they do have some incredible features that didn’t go unnoticed to our keen eyes.

So check them out and see for yourself what they have to offer.

- Go Power! GP-SF-5 SUNfilm 5 Watt Solar Panel -

More like a battery maintainer than a charger, this inexpensive little solar panel would be a great buy for keeping your batteries topped up.

Go Power! GP-SF-5 SUNfilm 5 Watt Solar Panel

Rating : 4.3/5

Leaving your batteries to idle until you plan on having your next boating vacation doesn’t sound healthy. Self discharging of batteries is very common and it would eventually shorten the life span.

That is when Go Power! GP-SF-5 comes in to the picture. It ensures your 12V battery is always topped up and ever-ready to be used anytime and anywhere. What’s more, you can also use it to charge your electronic devices while you put your feet up and have your time on water.


14 x 13.2 x 0.5 inches small in size and 3 pounds light in weight, Go Power! GP-SF-5 has a maximum power capacity of 5 Watts. At 260mA it could be easily used to charge and retain the charge of 12V batteries.

Though the chances of bringing back to life a completely dead battery is slim, it’s not impossible. But still, it would be better if you could at least semi charge your battery before you plug in this panel.


Carry your deep cycle marine batteries and other electronic devices hours away from land and worry the least with Go Power! GP-SF-5. Even if you don’t have a voltmeter, you can still check whether the panel is working through the LED which goes on as the current starts flowing.

The panel also has adaptors to charge your life’s necessities: like your mobile phone and your laptop.

But mind you, don’t even think of connecting it directly without a regulator. So use it only to charge 12V batteries and then to the devices via the battery.

The biggest con reported with regards to the panel is that the plastic parts on it cannot resist the charms of the blazing sun- it can melt! So avoid placing it under the mid summer direct sunlight. However, it is surprisingly weatherproof and can hold out against strong winds, snowfall, heavy rains and sleet.


Like most solar panels, Go Power! GP-SF-5 too, has a 5-year limited warranty from the date of purchase. Make sure to thoroughly check your warranty conditions before you use the panel so that you can claim easily on manufacturer’s and material defects.

The Bottom Line

Whether you’re an off-grid user or an environmentalist, or simply a mariner looking for means of saving gas, Go Power! GP-SF-5 would be ideal. While the power is pretty low at 5 Watts and not durable enough to last for decades, it is well worth a buy when compared to its price.

- Buying Guide: How to Choose the
Best Marine Solar Panel - 

The ‘Best’ marine solar panel could vary from person to person. What is best for us may not be the best pick for you because individual needs are usually worlds apart.

That is why we’ve pulled off a list and not just one top pick. You can leisurely go through this list before you make your choice.

But prior to going through our review list and opting, don’t forget that you have some homework to do. As we’ve mentioned earlier, the best or the ideal marine solar panel is a choice of your own.

We cannot make it on your behalf but we can certainly help you out. And that’s exactly what we are gonna do through our buying guide.

Let’s get straight to the heart of the matter - not every one of us is an electrician or an engineer. All the tech terms could be really confusing, not to mention the different brands, sizes and prices.

So allow us to break them down and make it crystal clear for you.


First and foremost, you need to get this right. Different panels advertise different capacities of power. In our review the maximum was 100 watts and the minimum was 5 watts. 50W and 30W were in between.

If your boat is bigger and needs more power, you will obviously need to choose a solar panel with a high wattage.

However, at times, multiple solar panels with small wattages could be cheaper and far more efficient than that with a high wattage.

So you not only need to compare and contrast the maximum power capacities, but also the watt hours pay day.


The rate at which current flows through the solar panel is directly linked with the time taken to charge your 12V battery. Every second counts and higher the voltage, the better.

Solar cell

There are different types of solar cells being used in manufacturing marine solar cells. But the most common cells are namely amorphous cells and mono-crystalline cells.

Amorphous cells usually produce only a low output but they are relatively cheaper than mono-crystalline cells.

On the other hand it is less efficient and short lasting. So if you have decades in mind, and a deep pocket, a mono-crystalline solar panel would fit in perfectly.

But then again, if your boat is small and has a low weight capacity, an amorphous solar cell would be better as it is lightweight.


Size matters, as always. To determine it, you need to first decide where you will be mounting your solar panel - whether on your boat or on any other place. Next, get your measuring tape and set to work. Don’t settle for any approximate measurements, measure it right. Only then will you be able to get a panel with the right size.


Durability is often ensured by the materials used to manufacture the solar panels. If it consists an aluminium frame, then it is way durable than plastic frames because plastics have reportedly melted under the direct, blazing sun!

Apart from that, if the panel is weatherproof, then you should totally consider buying it. The ability to withhold extreme weather conditions would not make you rush after it if a storm decides to hit unexpectedly.


Warranty is as important as other points we’ve listed here. But unfortunately, most customers don’t give it much thought. Some solar panels have a really long life, perhaps even more than 25 years. In such instance, a 1-year or 2-year warranty seems hilarious.

The conditions of the warranty is as equally important as the period of time. Certain manufacturers do not accept any manufacturing or material defects if the product is at least used once.

So a thorough inspection is a must. Our expert suggestion is to request a copy of a warranty and have a close look before you make a buy.


In most cases, the quality of your choice depends on the depth of your pocket. If you ain’t gonna spend more, you should be ready to accept less.

However, if you inspect well, you will be surprised to find marine solar panels that are greater in value than the price.

Our top picks here are such panels. So you can be confident in purchasing any of them.


For how long do you expect to reap benefits from a marine solar panel? If angling is your profession or your life-long hobby, then a long-lasting solar panel would do.

But from a logical standpoint, this actually depends on your budget.

Then again, there are low powered solar panels that last longer than high powered ones. So do your math and make your choice.


Performance is a key indicator of quality. A high ampere per hour, low charging time, good ratings are all part this.

All the marine solar panels listed in our review are the most highly performing ones available on the market today.

Choosing any of them according to your needs would undoubtedly be a big score.

Apart from these, there can be many more points that you’ll want to consider. Suppose you live in a shadier part of the country and don’t see much sun but still want to have your 12V batteries topped up and ready-to-action?

No problem, any of our best picks here would do. Some better than others, but still would work impressively with lesser amount of sunlight.

Just like that, you might have many more points to consider. But they are for homework, and we’ve mentioned the general points here.

However, the best part of our buying guide is that, if you follow the steps you won’t go wrong. So have a list of your expectations prepared and tick them off one by one as you leaf through our review. Finally, you can choose the one with the most ticks. Simple as that.

- Benefits of Marine Solar Panels -

Marine solar panels are generally known as ‘gas-savers’. Right, but how else could they benefit you? Here is a simple list.

 Not doing a good job at fishing? Stop taking all the blame, your generator or engine could be a reason too. Marine solar panels give you one of the best solutions by being less noisier and more environmentally friendly.

 Cuts costs - At a time when fuel is becoming increasingly scarce and pricier, solar panels act as a great alternative. They are durable too, which means you spend once and for all.

 Is your boat too small? This could’ve been a problem if you’ve been using a generator which is quite heavy. But with solar panels being lightweight, you can easily overcome this problem.

 Have your battery always ready to hit the water - A solar panel would do its duty and keep your 12V batteries topped up even when you’re not around.

And much, much more.

Our responsibility as expert reviewers is now complete. Now it’s your turn to take charge. Compare and contrast, clear all your doubts, and finally head straight to Amazon and place your order!
