We have come a long way since the days when people used to harness horses, bulls, and donkeys to drive their simple machines. Then someone invented the steam engine, soon we had internal combustion engine, and finally the electric motors.
Those great inventions enabled us to work faster and efficiently. However, we still don’t have the ultimate solution to our energy problem. Fossil fuels are easy to use, they pollute the environment and they are finite. Moreover, some day we are going to deplete oil reservoirs, and possibly fill the air with pollutants.
That’s why we need an alternative source of energy that is infinite and will not pollute the environment. Solar panels are the only thing that has brought us closer to that goal.
Some of them are pricey and may not be for everyone. However, their efficiency and durability makes them worth every cent you spend on them.
Top 10 Portable Solar Panels for RV Batteries 2019
1. HQST 100 Watt– Best Solar Panels for RV Use
The HQST 100 Watt 12 Volt Polycrystalline Solar Panel tops the list for its wonderful performance even under low light conditions. That maybe the reason why buyers love it the most, nonetheless, it has other features that make it stand out from the pack.
We will now take a deeper look at each feature that enables it to give more wattage for each dollar invested in it.
You may have used the Renogy 150 Watts 12 Volts Mono-crystalline Solar Panel and thought that it’s the best. Well, it’s a great panel, but you need to try the HQST 100 Watt 12 Volt Polycrystalline Solar Panel. It’s immense power generating capability makes it the ultimate answer to homeowner’s quest for affordable power.
While it delivers as much wattage as possible, it does not sacrifice on its design and compactness. Every inch that it covers is worth the wattage it outputs. I must say there are a few panels whose wattage output outmatches their price the way it does.
High Quality Glass: One of the biggest challenges of installing solar panels outdoors is debris. There is a chance that something might damage the delicate cells. Even snow or hailstones can damage your solar panel when they accumulate over time.
The high low iron-tempered glass provides impact resistance as well as stiffness needed to protect the solar cells. The low iron-tempered glass enables it withstands snow loads of 5400Pa and wind speeds of 2400Pa, which gives this panel the protection it needs to last over 30 years.
The glass is also anti-reflective and highly transparent. Together, those characteristics allow maximum light penetration into the solar cells. That is why it’s able to generate power even under low light condition, such as when there is cloud cover.
Easy to Install: The Pre-Drilled Holes on the frame of this solar panel give you greater flexibility when mounting and securing it. You do not need to invest in a drill or any special brackets brackets. This panel’s frame is also compatible with other mounting brackets that include tilt mounts, pole mounts, and Z-brackets.
High Performance: Most panels perform poorly when covered partially by trees or anything that casts a shadow on them but not this one. Its design incorporates bypass-diodes that prevent a reversed flow of current into the cells covered by shade.
Without that design, power generated by cells exposed to light would end up flowing into cells under the shade. The panel would therefore output minimal or no power because of the cyclic internal flow of current.
You can expect to get up to 500Wh on a good sunny day, enough to charge a 500Wh. You can draw a current of 25A for 20 hours at 12volts. That’s enough to power a small freezer the whole day and let it coast at night when the temperatures drop.
Reliable and Durable: The Sturdy Construction of the HQST 100 Watt 12 Volt Polycrystalline Solar Panel can be witnessed in the IP65 rated junction box. The box provides maximum protection from low-pressure water jets and environment particles such as dust and snowflakes.
That makes it easy to clean this panel without fear of corroding the panel’s contacts. The MC4 leads of this panel as designed to fit securely and you do not need specialized fasteners to connect them.
Cell Protection: Finally, the use of TPT to protect the cells from below means a longer a service and optimum performance for up to 30 years. The TPT is a thin layer or transparent hydrocarbon material that offers protection between minus 40 degrees Celsius and +110 degrees Celsius. It’s impermeable to moisture, dust, oil, and common other contaminants that might affect the solar cells.
It’s however important to note that the performance of mono-crystalline panels drops significantly when they’re partially covered. Other than that, we have not heard of any complain related to its performance, neither did we find anything wrong with it ourselves. It’s one of those products that the manufacturers did what the consumer expected them to do. If you need a reliable panel, this one will do the job very well.
2. WindyNation 100 Watt Panel Review – Best Off-Grid 12 Volt Panel
The WindyNation 100 Watt Polycrystalline Solar Panel is another panel that you would want to consider. This panel’s capacity to generate power even under cloudy conditions is amazing.
Most panels will do a good job on a sunny day but perform poorly as soon as there is cloud cover. If you live in places where cloud cover is a regular thing, then you need to buy this panel, otherwise it will take a lot longer to recoup your Investment.
Which is why we placed it in second position, in fact, it could have gotten a tie with the HQST 100 Watt 12 Volt Polycrystalline Solar Panel, but the latter is just more popular with most consumers. What makes this panel outperform other panels of its class? Let us have a look at its features and benefits.
Wattage and Power: The WindyNation 100 Watt Polycrystalline panel outputs as much as 600Wh on a good day, and about 300Wh when it’s cloud. To put that into perspective, if you have a battery rated 600Wh, an appliance can draw a current of 20A for twenty hours from that battery continuously.
At 12 Volts, that comes to 240 watts available for 20 straight hours. If you get three or four of these panels, you will get enough power for most of your basic appliances. That is why this panel is among the best for RV, Boats, and camping.
Grade-A PV Cell: Many manufacturers are not keen on the quality of cells they use in their panels. That’s why you find that you may buy a panel you thought was great, but then it turns out, it’s not as good as the reviews say it is. Sometimes, you buy two panels that look similar but when you try them, one outperforms the other under identical light conditions.
If you have been wondering why that happens, this is why: Some manufacturers do not grade their solar cells. The best panels are those that use graded PV cells and make sure they only use Grade A PV cells.
Better Performance: Grade-A cells outperform the marked wattage rating on the panel by about 10% because of their superior quality. Grade-B cells have a performance that is identical to the marked wattage rating, while Grade-C performs 10% less than the marked wattage rating on the panel. The difference in performance is caused by micro-imperfection in the design of the cells.
You cannot identify the imperfection by looking at the cells with your naked eye. That is why Windynation tops this list, they use laser scan to identify imperfections on cells and grade them accordingly. Furthermore, they choose only Grade A cells for their panels. That’s why their panels are able to generate power more power than their respective marked ratings.
Anodized Corrosion Resistant Aluminum Frame: Solar panels are made of metal frames to protect the modules from compression and tensional forces. While metals offer better mechanical protection, they need some structural modification to resist corrosion. Windynations panels are made of anodized aluminum to make sure that the panels can withstand corrosive weather elements for more than 30 years.
For consumers, that means they can leave their panels outdoors even in humid and salty conditions without worrying about corrosion. The anodized aluminum also helps to protect the cables attached to it from corrosion attacks, something that is common when you attach copper cables to iron frames.
It is Efficient: The WindyNation 100 Watt Polycrystalline panel has a high efficiency due to the superiority of their PV cells. They perform optimally at 45 degrees Celsius, take or give two degrees. While most panels will fail to deliver any power when partially covered, this panel will still work even when partially covered by shadows.
Size and Weight: Size matters especially when you need to install several panels on your roof. That’s why you will be happy to know that this panel measures 40 inches long, by 26.4 inches wide, by 1.2 inches high. That’s a small size when you consider the power it outputs, and that it’s a polycrystalline panel.
Two or three of these will fit perfectly on your RV roof. It weighs only 8Kgs or 17.6 pounds. You can therefore be able to install it on your own without any assistance if need be. However, when installing solar panels, it’s best to have someone assist you, especially if you will be climbing a roof.
Sufficient Voltage and Current: On a good sunny day, these panels will deliver as much as 21.60 volts on open circuit and 17.4 volts when connected to a load. The short circuit current is 6.32 amperes while the operation current is 5.75 amperes.
Multiple Applications: This panel is meant for use a source of power, it’s not a solar tile or fabric. Having said that, you can use it to supply electrical power to your home, RV, boat, cabins, or campsite. Unlike a diesel power generator, you don’t need to fuel a solar panel or service it after several hours of use. Overall, you will love this panel for its amazing and reliable performance as a clean source or electrical energy.
If you use polycrystalline panels in less than perfect conditions such as when they are partially covered by snow, shade, or dust, they outperform the mono-crystalline panels. Overall, this silent guy is among the best power producers you can have, both as backup and a primary source of power. You should definitely not hesitate to add it to buy it. It’s worth every cent you will spend on it.
3. ACOPOWER 100 Watts– Best Solar Panels for RV Use
The ACOPOWER 100w Polycrystalline Photovoltaic PV Solar Panel has not been around for long but it’s definitely one of the best solar panels you can buy. Whether you need to power a small pump, to use it in a dry camp or RV, or simply recharge your boat’s battery, this panel will do the job.

If you live in places where the amount of sunshine exceeds 6 hours, you will get a lot more than the marked rating of 600W.
Performance: This 100w Polycrystalline Photovoltaic PV Solar Panel offers an excellent performance even under low light conditions. Even when partially exposed to light. It still outputs some power, which is unlike the mono-crystalline panels don’t perform when the PV cells are partial covered. While that means you can use this panel day and night, you must use it with a charge controller to avoid ruining the battery.
Under very low light condition or under total darkness, this panel will tend to allow current to flow from the battery cells to its PV cells. This is what any panel does when it is not charging. That will drain the batteries by morning.
Fits to a Charge Controller: When that happens, most consumers think their panel didn’t charge the batteries properly the previous day. If for some reason, you don’t have a charge controller, then you need to buy one. It will prolong your battery’s life and protect this panel as well.

Frame and Junction Box: The panel’s frame is made of anodized aluminum to protect it from corrosion while the junction box is water proofed. The junction box is rated IP-65, and is able to prevent water and moisture from leaking into the panel’s underside. That sturdy construction is the reason this panel can produce power all year round with minimal maintenance.
Application: This panel can be used to supply power to any device that is rated 600W or less. You will of course need to have a battery to fill the gap when it gets dark outdoors or when there is cloud cover and the wattage drops, which happens with all panels under low light conditions.
However, with a battery bank of the right size and a matching number of these panels to charge it, you can be sure you will not experience any power shortage or outage. You can use it to light your security lights, power a small pump, use it as an off-grid power source, and recharge your RV or boat’s batteries.
Application Class: This panel belongs to class A Polycrystalline Photovoltaic Solar Panel. The panels use only the PV cells that are perfect output 10% more than the actual rating. This panel will therefore deliver more than a satisfactory performance when exposed to optimum light conditions as well as low light conditions. If you need the best budget solar panel, then the ACOPOWER 100w Polycrystalline PV Solar Panel is your answer.
I would recommend this panel for domestic use as well as outdoor use such as dry camping, in RVs, as well as boats.

8. ECO-WORTHY 500W Solar Kit -Portable Solar Panels for RV Batteries
It would be great if the batteries on your RV or boat lasted forever. However, that is not the case and the only way you can conveniently recharge them is to use solar panels. However, buying solar panels for your home or recreational vehicle can be challenging.
You need to find the best 500-watt Solar Panel that has the right efficient, of the right physical size and weight, is easy to mount and comes with a reasonable warranty period. In this review, I will look at what you can expect from a Renogy 500W Solar Panel.
The ECO-WORTHY 500 Watts Solar Panel kit balances between price and power. Its photovoltaic cells made of a poly-crystalline structure. It is therefore more efficient than thin film 500-watt solar panels. However, it is less efficient than mono-crystalline 500-watt photovoltaic panels. The good news is it costs less than its mono-crystalline 500-watt equivalent.
5pcs of 100-Watt Polycrystalline Solar Panels: The ECO-WORTHY 500 Watts Panel kit comes in five pieces of 100-watt polycrystalline solar panels. That means you get a total of 500 watts with an option to play around with the overall voltage and current output. If you connect this photovoltaic solar kit in series, you get a 500 watts solar panel kit at 60 Volts. When you connect them in parallel, you get output 500W at 12 volts.
45-Amps Solar Charge Controller: The ECO-WORTHY 500 Watts kit comes with a 45-Amp solar charge controller. The control enables the solar panels to charge the batteries when there is enough sunshine to generate power. When the level of sunshine drops and the photovoltaic cells stop generating power, the charge controller stops the batteries from discharging. It can handle current of up to 45 Amps, which is a huge current even for an RV or boat operation.
32-Feet 12 AWG Solar Cable: The 32 feet long AWG solar cable allows the ECO-WORTHY 500 Watts Solar kit to be mounted connected with ease. You can mount it on any domestic roofs as well as RV, boat, or shed. That makes this ECO-WORTHY 500W Solar Panel kit to stand out. Short or poorly designed connection cables can make installation of any Solar Panel a nightmare. That’s why I appreciate it that they made theses cable long enough. They need to cover the distance from the roof to the indoor power distribution panel.
MC4 Connectors: The MC4 Connector makes it easy to connect the ECO-WORTHY 500 Watts Solar Panel either in series or in parallel. You can use them to connect the ECO-WORTHY Solar Panel by hand.
