    Best Solar Panels Reviews & Recommendations 2020

    Best Overall

    This is a good monocrystalline kit for first-time users. It includes 100 watts of power and a 40A mppt charge controller that transfers up to 30 percent more efficiently than a PWM charge controller. If you want to build up the system, you can add up to 400W (12 volt) or 800W (24 volt) for additional power.


    The kit can be used on RVs, trailers, boats, sheds, cabins, and other off-grid dwellings. After an average day and night's use, the batteries are fully charged by mid-afternoon. Even on cloudy days, the panel is able to pull plenty of power. Since you can expand the kit, you don't have to buy all the panels at once, and the controller is good for four panels. Renogy customer service is also very helpful.


    One of the downsides is that the charge controller is a little flimsy, forcing some people to upgrade it. It has weak connection points for the battery and panel wires and may fail after a short period of use. Also, the instructions are not the best, and there have been complaints that they are incomplete.

    Best Value

    This 100-watt, 12-volt polycrystalline panel is sturdy, strong, and very affordable. It is designed for RVs, boats, and off-the-grid dwellings. It comes with a pair of pre-attached, three-foot MC4 cables, and the diodes are pre-installed in the junction box. The product includes a 25-year transferable power output warranty.


    One of the best things about this panel is that it is easy to mount. It is also designed to be expanded to fit multiple panels. It will produce small amounts of power, even on overcast and cloudy days. It is well-built and high-quality with a solid double-wall aluminum frame and tempered glass. Overall, it is a great panel and comparable in cost per watt to much larger panels.


    The biggest problem with this panel is that since it is polycrystalline, it works best when it is pointing directly towards the sun. If there's a shadow on the panel, the power can decrease by a large amount. Also, it’s on the heavier side.

    Honorable Mention

    This polycrystalline solar panel kit includes a 100-watt solar panel, adjustable 30-amp LCD display controller with battery temperature sensor, 40 feet of 12 AWG solar cable, MC4 connectors, and solar mounting hardware. It's expandable, so you can add additional solar panels at a later date.


    All items work as intended right out of the box. It can be used on RVs, homes, boats, cabins, or as a back-up or remote power unit. Depending on available sunlight, it provides an average of 350 watt hours (33 amp hours) of charge per day. It provides enough electricity to run two full-sized refrigerators 24/7, even on somewhat cloudy days.


    However, it can be a little difficult to install this solar panel kit, and the product may be missing some parts for installation. It doesn't come with any fuses, which you must purchase separately. In addition, the charge controller display may fail after a short period of use.

    Honorable Mention

    This solar charger from Rockpals is designed to fit as many portable solar generators as possible. With four different connectors that fit nine generator brands, including Suaoki, Paxcess, and Rockpals’s own generators, this is as close to a universal fit as you’re likely to find. It’s even able to charge USB devices like your smartphone.


    Built-in technology detects the generator type and optimizes the connection, easily hitting the sweet spot between slow charging and over-charging. Rockpals promises this panel will convert more than 20 percent of sunlight into energy, which puts it on par with the most efficient solar technology currently on the market. All that and it’s mostly waterproof, too.


    Our favorite thing about the Rockpals foldable charger is how easy it is to carry around. When folded up, it’s less than two feet across and just over one foot high. It’s light and compact, so it’s able to be taken pretty much anywhere.


    The big downside of this charger is that it’s feature-poor. There’s no way to prop it up, and no indicator of how much power it’s generating, which can make slower charges frustrating. Also, while most of the system is waterproof, the junction box is not.

    Honorable Mention

    The Goal Zero Boulder 100 is a monocrystalline solar panel, which means the entire panel is cut from a single silicon crystal. Monocrystalline panels are more efficient than polycrystalline panels, but since getting a whole solar panel from one silicon source is time-consuming, they’re also more expensive. The Goal Zero Boulder 100, though, is worth the extra money.


    This 100-watt panel is extremely versatile. It’s not hard to install permanently on your roof as an emergency or off-grid power source. However, it’s also light and comes with an aluminum frame that makes it a good solution for camping power. It’s even more convenient if you already have one of Goal Zero’s Yeti power stations.


    That convenience is an unfortunate double-edged sword. Goal Zero’s connectors make it easy to chain their solar panels together and plug into their own power stations, but adapting their solar power to other brands’ appliances requires an uncertain and expensive adapter. It’s also heavy enough that carrying it by hand is a slog—we recommend getting a vehicle involved.

    Honorable Mention

    Contrasting with the Goal Zero Boulder 100, the HQST Polycrystalline Solar Panel is made from multiple silicon sources. It’s cheaper, but less powerful: If you want to save money, be prepared to get your electricity at a slower rate.


    HQST’s polycrystalline panels are available at four power levels (100W, 150W, 200W, and 400W), each for an escalating price. We tested out the 100W and found it more than efficient enough for off-grid power. For the most part, it generated about 95 usable watts in direct sunlight, one of the best ratios of efficiency to price that we’ve ever seen.


    But there’s more to recommend HQST than just power generation. The glass is tough, reinforced with iron and treated to let in the maximum amount of light. The junction box is protected against wind, rain, and snow. It’s even been tested to withstand elements such as water jets.


    We only have two complaints. First, the wires are uncomfortably short, and might require extensions depending on where you choose to mount the panel. Second, the panels aren’t packaged well and might arrive with blemishes.

    Honorable Mention

    Like the Rockpals charging kit above, TP-Solar’s foldable panels are made to be hooked up to power stations. They also share Rockpals’ focus on a universal fit. The various connectors that ship with this kit are compatible with all the leading power stations, including Goal Zero, Jackery, Webetop, Paxcess, and Suaoki.


    This is a DC solar panel, so if you’re in the U.S., you might need an extra adapter; however, it’s still more than possible to make it work. With these panels, you get portable, widely useful power, able to charge everything from a smartphone to a marine battery. Weighing just over five pounds, they can be carried anywhere.


    Monocrystalline silicon construction helps them run at peak efficiency. Even when these panels couldn’t get direct sunlight, we regularly saw them drawing over 60 watts. On a partly cloudy day, or at sunset, that’s fantastic.


    Granted, there are some aspects of the construction we’re not fans of. The wires are extremely thin, which undoubtedly leads to some voltage loss. Also, the flap for folding up the panels is hard to secure, and often blows around when the panels are oriented any way other than directly vertical.

    Honorable Mention

    If you’ve been skimming past the 100-watt panels wondering when we’d list something with real power, here’s where you stop. The Eco-Worthy 195-Watt solar panel is an efficient, monocrystalline unit designed to be installed on recreational and marine vehicles. It’s capable of providing up to one kilowatt-hour per day, and can charge a 50Ah battery from half to full power in less than two hours.


    Take that statement with a grain of salt, as it only happens in perfect conditions. However, even out of direct sunlight, Eco-Worthy’s solar panel outperforms. Its other big advantage is how easy it is to install. If you’re new to off-the-grid or marine living, you can plug this in according to simple instructions, and get down to your other tasks.


    One other big plus with Eco-Worthy is the customer service. If anything doesn’t make sense or needs to be replaced, their experts are helpful and responsive.


    That’s good, because these panels do demonstrate a couple of potentially harmful design flaws. It’s unlikely, but possible, that poor soldering will make a unit unusable after several months. You’ll know this happened if you see burn marks. Also, you have to drill your own holes to install wires.

    Honorable Mention

    Here is another set of solar panels from HQST. Remember how we mentioned that their polycrystalline panels were good-quality, but didn’t reach their maximum output rating even in direct sunlight? Good news: If you want peak efficiency at an affordable price, HQST also sells more reliable monocrystalline panels.


    This kit is a “solar suitcase,” designed to be a complete solar power solution that’s easy to carry around. With the help of a controller made by Renogy, it near-perfectly achieves the goal of providing for all your off-grid charging needs. You can unpack this suitcase and charge your devices as easily as you would at home.


    As you might imagine, trying to be a total solution makes this suitcase heavy: about 27 pounds, to be exact. Its non-electrical structure is also much weaker than the parts providing power, with a flimsy aluminum stand and inconveniently short wires. You can fix these issues with some DIY, but we understand that’s not for everyone.

    Honorable Mention

    Rounding out the list, we’ve got this 12V solar charger from MOOLSUN, which is working to achieve a very different goal from the others. At only 10 watts of maximum output, this solar kit isn’t going to serve as an emergency power source, or do much to help you go off the grid. On the other end of the spectrum, it’s not great for phones or smaller devices.


    Instead, it’s entirely focused on one thing: recharging vehicle batteries. The good news is that it’s much more flexible in that department. MOOLSUN’s solar charger is equipped with a cigarette-lighter plug, an O-ring terminal, and alligator clips, making it compatible with batteries in your car, motorcycle, boat, or RV.


    Other than the incredibly low price, the main advantage here is user-friendliness. It’s especially good for maintaining a charge in a vehicle you won’t be starting for a while—as long as the vehicle’s in sunlight, it’s as straightforward as plugging in your GPS.


    That simplicity is also its main drawback. There’s no indicator, so until you try to start your engine, there’s no way to know if it’s actually working. Also, like all commercial solar panels, it almost never reaches its full output.

    Benefits of Solar Panels

    • Save money. One of the main reasons why people install solar panels is because they save them a lot of money. Over time, efficient solar panels will slash the cost of your electricity bill.
    • Use them year-round. While a solar panel system works best in the sunny summer months, the best panels also produce a lot of electricity in the winter (even on cloudy days).
    • No maintenance is necessary. Solar panels do not require regular servicing. While the inverter may need replacement every 10 to 15 years, that's about it. Otherwise, you’re good to go for an extended period of time.
    • Long-lasting. Many manufacturers in the solar industry back their products with a 25-year warranty because they're so durable. It's not uncommon to get as much as 40 years of service life from some solar panel companies.

    Types of Solar Panels

    Monocrystalline

    This type of solar panel is made of silicon wafers, which are stacked in a rectangular shape. They are cut from a single piece of silicon and contain black cells. Monocrystalline panels look black in color because of how the light reacts with the panel's pure silicon. The back sheets of these panels may be black, white, or silver, while the frame is usually silver or white.

    Polycrystalline

    These panels contain a melting pot of silicon crystals. They are rectangular and are covered in glass. While they are cheaper than monocrystalline panels, they are not as efficient. The combination of silicon crystals and sunlight produces a bluish shade on these panels. That's because light reacts differently with polycrystalline panels versus pure silicon crystals, which are used in monocrystalline panels.

    Thin-Film

    Thin-film panels are composed of several materials, including cadmium telluride (CdTe) as well as amorphous silicon (a-Si) and Copper Indium Gallium Selenide (CIGS). The a-Si panels resemble monocrystalline and polycrystalline panels, but they are not solid silicon wafers. Instead, they contain non-crystallized silicon that's inserted on top of glass or plastic. These panels are the lightest type but are not as efficient as monocrystalline.

    • Over $100: Solar panel off-grid, RV, or boat kits are going to cost you a little more than a single panel will. You may pay a few hundred dollars for a good starter kit, and they usually include everything you need to get a system up and running.

    Key Features

    Power

    Not all solar panels or solar systems generate the same amount of power. They each have a different wattage or power rating. The wattage indicates how much power a solar panel generates. Most solar panels are typically 250 to 350 watts, depending on what they’re used for. The ones in this review have less power, but are used for RVs and boats. Higher-wattage panels are usually more efficient, but they cost more and tend to be larger in size.

    Efficiency

    It's vital to have a solar panel that has a high efficiency so that it produces optimum power. The more efficient a solar panel is, the better it will be at converting sunlight into electricity. Look for solar panels with the highest efficiency ratings. Higher-efficiency panels have the ability to transform more sunlight into more power.

    Temperature Coefficient

    This is how a solar panel operates in conditions that are imperfect. Similar to other types of electronic devices, solar panels perform best when they are cool, i.e., less than 77 degrees Fahrenheit. The temperature coefficient informs you of the product's performance during really hot days. Electricity production will drop at each degree over 77 degrees Fahrenheit. For better performance, look for products with a lower temperature coefficient.

    Other Considerations

    • Size and Space: After you take into account quality and performance, you need to consider size. Determine how much roof space you have on your RV, boat, or off-grid dwelling. Will it accommodate the size of the product you are considering? In addition, how large are your energy needs? Will the selected panel provide for them?
    • Product Warranty: As we mentioned earlier, many brands offer long-lasting warranties. Make sure you know what you're getting before making a purchase. Also, choose a brand that is well-known and that will be around for several years to come should you need to contact them for repairs.
    • Tax Benefits and Incentives: Many people buy solar panels with the intent of taking advantage of local tax benefits. However, not every state offers the same incentives. In fact, these incentives can vary considerably, depending on where you live. For example, Connecticut offers both a property tax exemption and a sales tax exemption if you use solar panels.

    Tips

    • No matter where you use solar panels, make sure they are properly secured. This is especially true if you attach them to the roofs of RVs.
    • If you want to get the most out of your solar panels, consider manually moving them to follow and track the sun throughout the day.
    • Place stationary solar panels in an area with the most amount of sunlight. Make sure no shadows can reach them, or you will risk losing a significant amount of power.

    A: This depends on the type of device you are using. You also need to keep in mind how many different devices and appliances are in your trailer or home. In addition, calculate how much space around or on the roof you have for mounting the solar panels. The more panels you have, the more power they produce. To find out how much energy you need, you can find calculators online.

    Q: Are solar panels weather-resistant or waterproof?

    A: All solar panel manufacturers design panels to be weatherproof so they resist rain, snow, and dust. You can check with the specific manufacturer to see what weatherproofing they have fitted for their particular solar panels. 

    Q: What is the difference between monocrystalline and polycrystalline?

    A: Monocrystalline solar panels are made from a single crystal and feature a thin layer of silicon. They include small square cells across the surface and perform better in low light conditions. Polycrystalline panels are developed out of smaller crystals in each cell. They have rectangular solar cells and may also include a blue coloring.
