#2 Ring Solar Panel


WHY WE LIKE IT: The Ring Solar Panel is made specifically for the Ring Spotlight Cam and Ring Stick Up Cam. With easy installation and high performance, the Ring Solar Panel assures you’ll never need to change a battery in your smart home security cameras again.

Read Full Review: Ring Solar Panel Review

  • Best for Ring cameras
  • Requires minimal sunlight to charge
  • 13 foot power cable
  • Disappointing winter performance
  • Ring app doesn’t show solar performance
  • 1 year warranty

The Ring Solar Panel is made with one purpose in mind: charging the batteries in either your Ring Spotlight Cam or Ring Stick Up Cam. Since these are security cameras meant for the outside of your home, constantly changing batteries can be a hassle, but the Ring Solar Panel has fixed that problem. Measuring in at just 7.75 x 5.5 x 0.5 inches, this solar panel is compact and versatile. Its small size means you can install it nearly anywhere on your home without problem. Installation is also really easy, and all of the installation hardware is included in the package. Don’t worry if your camera is in a place where the solar panel won’t fit. You also get a 13 foot power cable so can install the panel away from the camera in order to get the best sunlight.

While the Ring Solar Panel’s performance isn’t much to talk about on paper with only 6V/2.2 watts of power output, it’s perfect for the Ring cameras. Of course, total output is dependent on sunlight exposure, but you should expect your batteries to stay charged throughout the day while using the solar panel, even on overcast days. Unfortunately, you might experience less-than-average performance in winter weather with the Ring Solar Panel, especially in temperatures below -5° Celsius. However, the Ring Solar Panels are built with durability in mind, and they can withstand tough weather, including snow and rain. The only disappointment in that area is the short, 1 year warranty you’ll get with your purchase. With your solar panels doing the work at home, you’re free to grab your best two person tent for a weekend camping trip.

#3 RAVPower Foldable Solar Panel

We’re sorry, this product is temporarily out of stock


WHY WE LIKE IT: The RAVPower Foldable Solar Panel is portable, durable and lightweight, making it the perfect addition to your camping gear. It produces enough power output to charge all your portable devices via USB, whether on cloudy or clear days.

Read Full Review: RAVPower Foldable Solar Panel Review

  • Best for camping
  • Smart charge functionality
  • Slower charge time
  • D rings could be sturdier

Extra batteries do nothing but add weight and take up extra space in your camping gear, making them inconvenient for serious camping trips. The RAVPower Foldable Solar Panel solves that problem completely. This solar panel can be folded into a compact and lightweight package that fits easily into a pack. When you’re ready to use it, simply unfold it and plug in your devices to charge. The RAVPower can charge up to three separate devices simultaneously via USB. It outputs up to 16 watts of power with an efficiency between 21.5% and 23.5%.

The RAVPower also uses “iSmart” technology to automatically adjust power output based on the specific device you have connected to the unit. If your camera needs more juice than your phone, for example, the solar panel will dole out the appropriate amount of power to both devices without overcharging and ruining their batteries. While it isn’t the fastest charge of all time, the convenience of charging while away from an outlet is well worth it. If you need a durable and reliable power source while camping, the RAVPower Foldable Solar Panel is the choice for you. While you’re at it, pick up the best flying insect spray to keep your camp bug free.

#4 Arlo Solar Panel


WHY WE LIKE IT: If you have Arlo security cameras installed at your house, then you absolutely need the accompanying Arlo Solar Panel. This handy little solar panel keeps your Arlo cameras charged at all times without succumbing to weather conditions or difficult installations.

Read Full Review: Arlo Solar Panel Review

  • Never change a battery again
  • Easy installation
  • Good performance on cloudy days
  • 6 feet power cable
  • Only available in black

Like the Ring Solar Panel above, the Arlo Solar Panel is made specifically for Arlo-brand security cameras. More specifically, this solar panel is compatible with both Arlo Pro and Arlo Go cameras. When connected, this model will provide a continuous charge to your camera’s battery so you don’t have to swap the battery out to charge every so often. Instead, the solar panel draws energy from the sun and uses it to charge the battery. Since these are small batteries, the solar panel is really only good for this single application, which limits its overall versatility. However, it does this one thing extremely well.

Even on cloudy days, the Arlo Solar Panel’s performance was impressive. During our research, we never once noticed our batteries falling too low. Installation was also super easy. You get all the mounting brackets and hardware with your purchase, and the instructions are very clear and easy to follow. The only downside to installation that we noticed was the length of the included power cable. At only 6 feet, you won’t get much flexibility in placement. Keep this in mind as you plan your installation. Some might consider the connector between the power cable and the camera to be too snug, but we found it to be good for weather resistance. If you also want a match to brave the elements, take a look at the best all weather matches on the market.

  • Best for solar generators
  • Compatible with many solar generators
  • Includes 3 quick charge USB ports
  • Heavier than other options
  • No kickstand for angled charging

The Rockpals 100W foldable solar panel is the best foldable option on our list. It’s easy to unfold when you’re setting up and fold up when you’re packing your things. Once folded, it measures in at 20.5 x 14.2 x 2.6 inches, making it one of the most compact options on our list. Unfortunately, it’s a little heavier than other options, weighing in at 5.4 pounds, but it’s by no means too heavy to pack around.

One of the best things about the Rockpals foldability is that it doesn’t sacrifice performance and functionality. It’s compatible with most solar generators, but it also includes three Quick Charge USB ports so you can power all of your portable devices with ease. And with smart charging technology, you don’t have to worry about overcharging the batteries of your devices.

Read Full Review: Newpowa 100 Watt Monocrystalline Solar Panel Review

  • Best marine
  • Pre-attached MC4 cable
  • Easy installation
  • Lower winter performance
  • No mounting brackets included
  • 2 year materials warranty

If you’re looking for a solid solar panel to use on your boats or in other marine applications, look no further than the Newpowa 100 Watt Monocrystalline solar panel. This solar panel is more compact and lightweight than previous NewPowa iterations, which makes it even better for boats, where space for solar units is increasingly limited. They’re also rated to withstand high winds and wet weather conditions, making them even better for marine applications.

The Newpowa solar panels offer a high level of efficiency at around 21%, even during cloudy weather or partial shade. The solar panel is easy to install overall with pre-drilled mounting holes, but the package doesn’t include any kind of mounting hardware, which was a bit of a disappointment. Finally, the Newpowa solar panels include an impressive 25 year power output warranty, which is even transferable, but a disappointing 2 year materials warranty.

How We Decided

During our research, we wanted to guarantee our Top Picks solved your RV, boat, or home solar power dilemma, so we focused on solar panels that could provide the most energy in the most efficient manner possible. In order to make the cost of solar energy efficient, you need to be able to produce energy cheaper than what traditional power sources would cost. This efficiency is measured in a variety of different ways, ranging from how much sunlight exposure they can convert to consumable power, along with the temperature coefficient of the unit.

When you combine that efficiency with the price of purchasing the solar panel itself, you get a better picture of the overall value of the product. Try to find something that makes sense for you and your home, RV or other application.

We also considered the difference between solar panels for your exterior smart home devices like security cameras vs. larger solar panels meant to power your home, RV or boat. We didn’t weigh one heavier than the other. Instead, we focused more on each specific panel’s ability to power whatever application they’re connected to.

We also measured each option on our list based on its ease of installation. The best solar panels should be easy to install and include all the necessary mounting hardware. They should also include clear instructions so you know exactly what you’re doing during the installation process, including how to appropriately connect all of the electrical components.

Finally, we also took into account the solar panels’ warranty. Large solar panel applications often carry two separate warranties: a materials warranty and a performance warranty. Materials warranties should be 5-10 years while performance materials should be around 25 years. Solar panels for smaller applications like smart home devices and solar generators often carry a standard 1 year warranty.

Best Solar Panel Buyer’s Guide

The Most Important Features to Consider

  1. Power Output
    The amount of power you need from your solar panels depends largely upon the application you’re using them for. Powering an entire home with solar energy will require more output than powering an RV or generator. Most individual solar panels will output anywhere from 100 watts to 400 watts. When you combine multiple panels, you’ll be able to achieve higher levels of power output in order to power larger applications.
  2. Solar Panel Efficiency
    The most important feature you should consider when purchasing new solar panels is how efficient they are. This is a measure of how well the solar panels can convert sunlight into electricity for your home. Each solar panel product available today has a specific efficiency rating, measured in a percentage. Most solar panels offer an efficiency rating of 15% to 20%, with the absolutely best options exceeding ratings of 22%.
  3. Temperature Coefficient
    While you may think that solar panels would improve their performance on hot and sunny summer days, they’re actually just like other electronics in the fact that they perform best in cooler temperatures. The temperature coefficient will tell you how much your solar panels’ efficiency will decrease on those hot days. You’ll want to purchase panels with a lower temperature coefficient, which is measured in percentage of efficiency lost per degree Celsius (%/°C). For example, if your solar panels have a temperature coefficient of -0.5%/°C, it means your efficiency will decrease by 0.5% every time the panels’ temperature increases by one degree Celsius. If the temperature rises by 10 degrees Celsius, then the solar panels will produce 5% less electricity for your home.
  4. Warranty
    As you can imagine, solar panels go through a lot while attached to your roof 100% of the time. Depending on where you live, they may have to endure rain, snow, hail, hot sun and more. This is why it’s so important that you purchase solar panels that have a solid materials warranty attached to them. At the minimum, you should purchase panels with a 10 year materials warranty, but the best manufacturers will include a 15 or even 20 year warranty. Another thing to consider when it comes to warranty is coverage for diminishing performance over the lifetime of the solar panels. For the most part, solar panel manufacturers will include an additional performance warranty on top of the materials warranty. This performance warranty guarantees that the solar panels will maintain at least 80% of their original performance over the life of the warranty, which is usually around 25 years.

Solar Panel FAQs

What is the best solar panel?

The best solar panel on our list is the Renogy 100 Watt Monocrystalline Solar Panel Starter Kit. With a durable construction, high energy efficiency and low temperature coefficient, these solar panels are perfect for a wide variety of applications, including both homes and RVs.

What is the most powerful solar panel?

The most powerful solar panels offer up to 400 watts of power, but these are a little out of scope on our list. The most powerful solar panel on our list is the Renogy 100 Watt Monocrystalline Solar Panel Starter Kit. You can link multiple panels together for even great power output for larger applications.

What are the 2 main disadvantages to solar energy?

The two of the main disadvantages to solar energy that those opposed to solar bring up most often are the need for constant sunlight exposure and the need for oftentimes large installation areas. These “downsides” are mostly myths, though. You can still use solar in areas that don’t get sun 100% of the time and you can even work with smaller installation spaces. While cloudy days and smaller installation spaces may not give you the maximum efficiency that solar panels can provide, it doesn’t mean you should avoid solar outright.
