Solar Battery Charger vs Solar Panel: What’s the Difference?

You might be wondering what the difference is between a solar battery charger and a solar panel.

A solar panel converts electricity into sunlight. That’s it. Pretty simple, right?

A solar battery charger, on the other hand, is a solar panel with a few extra components tacked on so you can easily and conveniently charge your battery.

So a solar battery charger includes a solar panel, as well as wires to connect the solar panel to your car battery or USB ports to connect your smartphone or tablet, and can include a few additional tech items like charge controllers and blocking diodes (more on those later).

Of course, you could make your own solar battery charger with a solar panel, some wires, and a few other pieces of gear, but the beauty of solar battery chargers is their simplicity and ease of use. Just put the solar panel in the sun and connect your battery. It’s that easy.

Before we move on, here’s an important distinction. Solar chargers for 12 volt applications like cars, RVs, and boats are designed to only maintain your battery’s charge when not in use. These small solar chargers aren’t big enough to fully charge dead batteries, so instead they just trickle charge the battery, ensuring they’re always ready for your next adventure.

Solar chargers for smartphones and tablets, however, produce the 5 volts your iPhone actually needs to recharge after a complete discharge. Needless to say, solar chargers for vehicles and smartphones are quite different, and are NOT interchangeable. However, we include them all here, as most of us collectively refer to all of it as solar battery chargers.

Best Solar Battery Charger for Cars: Battery Tender Solar Charger

Quick View: A physically large, waterproof solar charger that comes in three sizes, from 5 to 15 watts, built-in controller and diode

If you’re looking for a well-built, leave-it-and-forget it solar battery maintainer for your car, Battery Tender’s Solar Charger is the perfect solution. It’s heavy-duty, waterproof, and comes with everything you need to keep your battery topped up with free, clean energy.

Battery Tender’s been around for ages and you can find their products online and in person at stores like Walmart and local auto parts store. On Amazon, you can find their Solar Charger in 5, 10, and 15 watts. Each comes with alligator clips to attach to your battery, but not much else.

It’s waterproof, so you can leave it outside, but remember it’s quite large – the 15 watt panel is over 3 feet long and a foot wide! However, it’s got some great features that set it apart from almost every other solar charge controller out there.

First, Battery Tender’s Solar Charger includes a built-in charge controller to protect your battery from over-charging and possibly suffering from premature death.

Almost all other solar chargers don’t include a controller, leaving you to hope you never have any issues or forced to buy one more piece of equipment for your solar battery charge system. Some manufacturers and/or users argue that including a charge controller on solar panels this small is overkill, but it certainly takes all the worry away wondering whether you should use one, since you’ve already got it.

Second, Battery Tender also includes an integrated blocking diode in their solar chargers. Without a blocking diode, your battery can actually leach electricity to your solar panel at night, leading to a dead battery. If you don’t have a blocking diode in your solar charger, you have to disconnect your battery from your solar charger every night.

People use these solar chargers for all sorts of vehicles: boats, RVs, cars and trucks, and camper trailers. Some even permanently mount the solar charger to the front of their camper trailer. Customers confirm the charger’s great performance stats and noted that, even though the chargers are quite large, they’re lightweight and easy to maneuver.

If you’re looking to keep your car topped up, you can simply place the solar panel on your dash and let the sunlight do its work.

Bottom Line: Battery Tender’s Solar Charger is a bit more expensive than others on our list, but you get an integrated charge controller and blocking diode. Even though it’s larger than others on our list, with these nice additions you don’t have to worry about your car’s battery. It’s one of the safest, easiest chargers to use.

Best Solar Battery Charger for Boats: DuraVolt 20W Marine Solar Battery Charger

Quick View: DuraVolt’s sturdy solar chargers are specifically designed for heavy-duty marine use

Solar panel manufacturer ITC Solar originally manufactured their DuraVolt solar panels to power high-tech buoys designed to monitor water quality in Tasman Bay in New Zealand. Realizing recreational boaters and other industries could benefit from these small, durable solar panels, they branded them as DuraVolt and now you can find them on Amazon.

These solar chargers are semi-flexible and covered in a plastic film and aluminum backing. The solar charger is wrapped in a heavy duty rubber gasket with a mounting hole in each corner. Their 20 watt solar charger is quite small, at 14” x 16” and just 1/4” thick.

The solar chargers come pre-installed with an SAE output plug, as well as alligator clips, battery terminals, and a lighter adapter so you can charge your boat in whatever manner is easiest.

An important note: The charger doesn’t come with a blocking diode or charge controller.

DuraVolt claims that electricity loss is so little thanks to their solar panels’ high-quality internal components that a blocking diode is unnecessary, though they’ll send you one for free if requested. Also, a handful of buyers have installed blocking diodes or kill switches themselves to avoid any potential issues.

DuraVolt also notes that their 12v chargers don’t need a charge controller, as they use self-regulating panels with a lower operating voltage than other 12v solar panels. A handful of buyers still use a charge controller, but the manufacturer notes it’s not necessary thanks to this low voltage.

Many buyers permanently attach the charger to the deck or T-top and use it to keep the battery topped up when moored or when out on the boat during the day.

Customers continually praise the charger’s simplicity and toughness. All you have to do is bolt it down, put on the right adapter, and connect it to your battery.

Bottom Line: The DuraVolt 20W Marine Solar Battery Charger is the perfect option for your boat or any other intense setting where ruggedness and dependability is key – and water is imminent.

Best Solar Battery Charger for RVs: DuraVolt Magnetic Battery Maintainer

Quick View: Thanks to the ultra-strong magnetic back, DuraVolt’s Magnetic Battery Maintainer is about the easiest solar charger to install.

We looked at DuraVolt’s Marine Solar Charger above, but their solar chargers are not just for boats. DuraVolt also manufacturers a magnetic solar charger based around the same extremely rugged solar panel as their marine products.

Their Magnetic Battery Maintainer is specifically designed for fifth wheel and camper trailers. The 8.3 watt solar panel has an extremely powerful magnetic back that sticks to any surface, including your fifth wheel’s hitch or even the hood of your vehicle.

DuraVolt uses neodymium magnets, the strongest magnet on the market, for these chargers. Many users note that, while skeptical initially of the strength of the magnet, they don’t move an inch even after high speeds and bumpy roads. This makes DuraVolt’s magnetic solar panel – quite literally – the easiest installation of all the chargers on our list!

Just like DuraVolt’s marine charger above, this solar panel is covered in a semi-flexible plastic film and aluminum backing for maximum durability, while also making the solar panel incredibly light. It’s 12” x 10”, just a ¼” thick, and weighs 1.9 pounds. As the solar panel is semi flexible, it can flex to the curve of your vehicle’s hood or any other metal, ‘gently curved’ surface.

The charger includes a 10 foot cord that ends with an SAE output as well as alligator clips and battery terminal adapters.

DuraVolt claims their solar battery chargers do not need a blocking diode or charge controller, thanks to their unique design and quality components. Some buyers choose to add one or the other, or both, after buying the kit, but most seem to just install what’s included without any additions and report the charger still works great.

DuraVolt customers typically have two things to say about the company. First, their solar panels are incredibly durable. You’ll certainly pay more for them, but you’ll also know your RV’s battery will always be ready to go. Second, DuraVolt’s customer service is excellent. Wait time is short, there’s no long phone prompt menu, and the employees are knowledgeable.

Bottom Line: DuraVolt’s Magnetic Battery Maintainer might be more expensive than other similarly-sized battery chargers, but it’s easy to install, extremely rugged, and backed up by excellent customer service.

Quick View: A compact, low-cost solar charger with great reviews.

Keeping your motorcycle battery topped up in the off-season is easy with POWOXI’s compact, 100% waterproof 3.3 watt solar charger.

The charger uses amorphous silicon solar cells, which perform well in low-light conditions. At 3.3 watts, you should have more than enough power to keep your bike’s battery charged up. The solar panel is encased within UV-resistant ABS plastic and includes mounting holes in each corner, along with suction cups to mount the panel.

The charger itself is 14” x 8.5” and just under an inch thick. This small size and the low weight of just 2.2 pounds makes this charger extremely portable and easy to set up. It includes a 10’ cord ending in an SAE output, with alligator clips and a cigarette lighter adapter (if you want to charge a vehicle).

POWOXI also integrates a blocking diode into the charger, so you’re able to leave the charger connected to the battery 24/7 without fear of damaging it (read more on blocking diodes at the end of this article).

The solar panel also includes a small blue LED light right on the front which flashes when its charging your battery – a nice little touch that allows you quickly keep tabs on your battery’s current state of affairs.

This kit doesn’t come with a charge controller, but most experts agree that any 12v solar kit under 5 watts doesn’t need a controller, so you should be good to go without one.

Of course, this solar charger isn’t just for motorcycles. Customers report using this little battery charger for jet skis, RVs, trucks, and cars. And many report it works great in low light, cold weather, and extreme heat – exactly what you want to hear for an all-weather, outdoors solar charger.

If you want to shave some costs, you’ve got a couple options. Fist, POWOXI also manufactures a monocrystalline version of this same solar charger for a bit less. It won’t produce as much electricity in low light conditions, but if you’re just going to connec the charger and leave it for a full season, it’ll work just fine and save you a few bucks.

If 3.3 watts is still too big for your needs, POWOXI also manufactures a smaller 1.8 watt version at about half the price, so take a look at that one if funds are low.

Bottom Line: POWOXI’s solar battery charger is low-cost, compact, and easy to set up, perfect for winter when your motorcycle is covered.

BigBlue though has solved the issue by including a chip that automatically pauses charging when shaded, then restarts when sunlight is available again. Needless to say, this allows you to not worry about your charging and just enjoy your experience.

The device even includes a built-in ammeter, so you know how much electricity your solar panels are producing. This is the only charger on our list that has this very helpful feature!

The solar charger measures 11” x 16” x 1” when closed, and weighs just 21 ounces. Basically, it’s smaller and lighter than a laptop, so it’s easy to throw in a backpack when you’re on a day hike or moving around the city all day. Once unfolded, you’ll find four small solar panels wrapped in heavy-duty, waterproof canvas.

This is one of the more popular solar chargers for iPhones and other smartphones, and for good reason. Users routinely say the charger is durable, fast-charging, and well-priced.

Some seemed disappointed that the charger doesn’t provide a full 28 watts, but unless you’re in absolutely perfect conditions, no solar panel is going to provide its nameplate wattage – that’s just how it works.

Bottom Line: BigBlue’s solar charger is the perfect option to charge your iPhone. It’s extremely portable, low cost, and well-made.

Pros and Cons of Solar Chargers

Solar chargers are a great way to keep your batteries easily charged up, but they’re not perfect. Let’s take a look at the pros and cons of solar chargers.

Pros of Solar Chargers

  • Free energy: This is an easy one. Once you buy the solar charger, you never have to pay for electricity or generator gas to top your batteries up. Use it for a year or 20 years, your fuel costs will be the same: absolutely zero.
  • Charge without utility power: This is the biggest draw to solar chargers. Since they’re powered by the sun, you’re able to charge your devices anywhere there’s sunlight. On your boat, while camping, in your RV, your driveway – you name it! No longer do you have to worry about moving your batteries into the garage or running cords outside. Just hook the charger to your battery and put the solar panel in the sun!
  • Easy setup: No need to take out your batteries or move your boat or ATV close to the garage. Just hook your battery or smartphone up to your solar charger and place the charger in the sun. Done!

Cons of Solar Chargers

  • Not too powerful: Solar chargers typically only produce about 2 to 30 watts of electricity, depending on intended use. It’s more than enough to keep your battery topped up, but that’s really not a lot of electricity at all. You’ll need to base the size of your charger on your own needs. The more you use the battery, the bigger your solar charger needs to be. If you want to keep two batteries fully charged, you’ll need to buy two solar chargers.
  • More expensive: Solar battery chargers are more expensive to purchase than plug-in chargers. That’s just a fact. Of course, with a solar charger you don’t have to pay for any electricity, but we add this to the list of cons to keep everything balanced.

Overall, we think the flexibility, functionality, and ease of use of solar-powered battery chargers easily make up for their higher purchase price. If you’re looking to keep your vehicles’ battery or smartphone topped up, solar chargers can get it done.

Charge Controllers and Diodes

If you’re looking at solar chargers for cars or boats (or any other 12 volt application), you’ll probably see a lot of discussion around blocking diodes and charge controllers and whether this or that particular product needs one. But what the heck are they? And are they even important?

Blocking Diodes – You Need Em!

Most of the better solar chargers include a blocking diode integrated into the solar panel. The diode allows electricity to flow towards the battery, but blocks electricity following in the opposite direction. Without a blocking diode, your battery can actually send electricity back to the solar panel at night, when the panel isn’t producing electricity.

If your solar charger doesn’t have a blocking diode, you’ll need to disconnect the charger from your battery each night. With a blocking diode, you don’t have to worry about this unnecessary waste.

Unless the manufacturer specifically notes that blocking diodes aren’t necessary (like DuraVolt above), make sure your solar battery charger includes one!

Charge Controller – You Might Need It

Charge controllers keep your solar panel from overcharging and damaging your battery. For large solar installations, they’re a required piece of equipment. Small battery chargers though usually don’t include a solar charger and many manufactures note that small 12 volt solar panels really don’t need a controller, as they don’t provide enough juice to overcharge the battery.

Others however recommend purchasing and using a charge controller for any solar panel larger than 5 watts. Many people report they use their solar battery charger without any charge controller and haven’t experienced any negative issues.

However, if there’s ever any voltage spikes or your battery charger is left connected to your battery for an extended period of time, there’s a chance you could damage it.

If you’re worried at all, it’s probably best to either buy a solar charger with an integrated charge controller (like the Battery Tender above) or spend the extra $20 on a separate charge controller.

Tips for Choosing the Right Solar Charger

Solar battery chargers are pretty simple pieces of equipment. They’re just solar panels with some cords attached. Still though, there’s a few things you need to know if you’re in the market. Here’s a couple tips to help you find the right solar charger for you.

Size

With solar chargers coming in sizes from 2 watts up to 30 watts, finding the right size for your needs is key. You want it to be big enough to keep your battery topped up, but not too big to the point where you’re just wasting money.

Most solar chargers for vehicle batteries come in around 5 to 15 watts. Larger vehicles typically require larger batteries, but it really depends on your vehicle’s phantom loads (ie power pulled from the battery even when the key isn’t in the ignition) and driving frequency. If you’re worried, 10 to 15 watts should be enough to keep any vehicle ready for use.

If you’re looking to charge your smartphone or tablet, you’ll probably want a larger solar panel. Most solar chargers for small devices sit around 15 to 30 watts, with the average around 22 to 28 watts. Exactly how many watts you need depends on the specific devices you want to charge, as well as how many devices. We recommend 20 watts or more for general use.

Features

If you’re looking for a solar charger for your 12 volt battery (in other words, for your car, boat, or RV), you’ll want your charger to include, at least, a blocking diode (see above), and the correct cords for your application (alligator clips for short term use, battery terminal rings for long-term storage, cigarette adaptors if you want to charge in the car, etc.)

On top of that, you’ll want to ensure the panel can be installed in the manner you’d like. Does it have mounting holes in each corner? Can it be glued down or not? These questions are easily answered by reading the description and customer reviews, or even asking a question to the extremely-helpful Amazon community.

If you want to charge your 5 volt gadgets (smartphones and tablets), you’ll need to ensure the charger has enough ports for your needs (usually 1 or 2 USB ports) as well as the right type – USB, USB-C, etc.

Also, how about mounting? Does it have holes in each corner? Does it come with carabiners or suction cups to clip or stick to different surfaces? Take a second to read the description and reviews to see exactly what features come with the charger.

Cost

Solar battery chargers really aren’t expensive at all, typically falling between $20 and $60, depending on the size of the solar panel and the features included. The higher end models can come in at $100+ and tacking on a battery pack can add even more.

If you’re looking at solar chargers for your vehicles or boat, you’ll find that solar chargers are a bit more expensive than a typical battery charger that you plug into your wall. However, the benefits of a solar charger, their portability and versatility, far outweigh the slight cost increase.
