How to Choose the Right Solar Panels for an RV
Despite being simple to use nowadays, RV solar power systems can be a little intimidating to the uninitiated. For more information you can check out our RV electrical systems guide here.
The truth is it helps to know a little bit about them in order to not only feel comfortable relying on solar 40 miles from the nearest gas station but to also pick the best one for your experience and off-grid solar power needs.
So, let’s start by taking a closer look at some RV solar panel kits and go over how they work, what features you need to consider, and lastly, how to calculate your energy needs. Then, we’ll get to the good stuff.
Solar Panels for RV – How Do They Work?
Solar panel kits make use of panels constructed of solar cells. These cells absorb energy from the sun and convert it into electricity (or as we like to call it, “free power”).
That’s the general concept. In more explicit terms, photons from the sun, which contain natural kinetic energy, continuously hit the silicon wafer of a solar panel. When they do, electrons are released, creating electricity that then flows through the panel’s cells.
However, RV portable solar panels don’t store electricity; they merely generate it and act as a power source.
The Direct Current flows from the cells through the PV wires and to the inverter, where it’s converted to usable Alternating Current power. Then, it runs through the charge controller, which stabilizes the voltage before reaching the battery where it’s stored for use.
RV Solar Panel Kits – Key Features
While there are a few solar kits for RVs that stand out ahead of the rest, the right one for you will largely depend on your RV and specific energy needs.
That said, all good RV and motorhome solar panels and kits have some common key features:
The solar panel is the meat and potatoes of any kit. It allows you to capture the sun’s energy, and with higher-quality RV solar panels, you can even do so on days when the sunlight is less than ideal.
As mentioned, each panel is made up of solar cells, with each cell made of silicon. The purer the silicon used and the better the construction of the cells, the higher the output and the greater the conversion efficiency of the panel.
When shopping for RV solar panels, you’ll find two types of portable solar panels to choose from. Monocrystalline solar panels are constructed from purified silicon, making them more efficient and effective. Polycrystalline solar panels, on the other hand, have less pure crystalline structures, making them less efficient but also less costly.
If you’re living or camping in an area with limited sunlight, you’ll want to go with higher-grade monocrystalline panels. However, if you’re in the desert southwest or somewhere with plenty of sunshine, polycrystalline panels will likely serve you just fine.
Unless you only plan on setting the system up on the ground next to your battery bank while camped for a day or two at a sweet little spot, you’ll need enough roof space to mount it without obstruction by the air conditioner, antenna, or other hardware.
The energy produced by RV solar panels isn’t steady. Instead, it surges and ebbs and flows, which can damage or affect the performance of the battery.
A solar charge controller solves this dilemma. This device, which is included in every solar kit, uses a process known as pulse width modulation (pwm) to automatically regulate the electric pulses being sent from the solar cells to the battery.
By receiving a steady supply of electricity, the battery is able to charge more quickly and maintain its charge level.
Batteries aren’t included in most solar panel kits for RV travel, but they’re a critical component of RV solar setups and worth discussing. Without a battery bank, you can’t store the power generated from your solar panel for later use.
Most RV batteries are 12 volts and rated for 100-ampere hours (Ah). A 100Ah battery can supply you with 100 amps of power for one hour, 10 amps for 10 hours, one amp for 100 hours, and so on.
However, you should never run your battery all the way down to the point where it’s fully discharged. Doing so can result in permanent damage.
Ideally, installing a solar panel should provide enough power to recharge your batteries and keep them above 50 percent. If not, you may need a generator or an electrical hookup to keep them level.
Batteries only store energy as direct current (DC). However, most appliances and devices run on alternating current (AC). A power inverter is needed to convert the power from DC to AC.
Power inverters are rated in watts. A 1500W inverter should be just fine for operating a TV, laptop, lamp, coffee maker, and other small appliances. Still, you’ll need a more powerful inverter to run an air conditioner, refrigerator, and other large appliances.
Just remember, the more power you use, the sooner your battery or batteries will need to be recharged.
To maximize the efficiency of your RV solar setup and make sure you have enough power to stay comfortable in the great outdoors, you need to calculate how much solar power you need.
Remember, the number of ampere-hours (Ah) your batteries can store will determine how much power you’ll be able to use. Meanwhile, the output of your RV solar panel kit will determine how quickly you’ll be able to recharge your batteries.
How to Calculate Your Solar Power Needs
Calculating your power needs comes down to a little math. Let’s start with the conversions.
To convert AC to DC, simply multiply by ten: 10A AC = 100A DC.
Conversely, to convert from DC to AC, you divide by ten: 100A DC = 10A AC.
Why is this important? Well, let’s say your TV runs at 110V AC, which most do, and is rated for 90W. Since Amps = Watts/Voltage we can then calculate that this will draw around 0.81A AC. When we convert it to DC, it draws 8.1A DC.
So, using this example, watching an hour of TV would use 8.1Ah. If you have a 100Ah battery, you would be able to watch around 12 hours of TV before depleting the battery.
However, since you should keep your battery above 50 percent, you would in reality only be able to watch around six hours of TV per charge.
By considering the devices and appliances you plan on using, thinking about how many hours per day you plan on using them and taking note of how many amps they draw, you’ll be able to put together a plan of how much solar power you’ll need.
Not only will you need an RV solar panel kit capable of producing the solar power you need, but you’ll also need enough batteries to store it to genuinely enjoy living off-grid.
