How to Choose the Best Portable Solar Panels for RV Battery Charging?

Below are the best buying guides that helps you get the right solar panels that suit your preferences and needs.

Solar power

It’s a vital consideration as it determines whether you will have enough battery power for your needs.  Bear in mind that portable solar panels are suited for smaller uses. 

RVs needs portable solar panels suited to its needs and can meet your different power needs. Factor in the number of people using the RV.  One person doesn’t need much power like three or four people do.  Therefore, pick the right solar panels based on the power output and your usage.  For a family, you need more power which translates into panels with more solar power output.

Installation, carrying and portability

Installation is a scary topic for many people.  However, not all solar panels need professional installation. Portable panels are convenient and easy to install. Most portable solar panels don’t have complex installation procedures. The instructions are simple and easy to understand.

Standing technique

It’s better to get a portable solar panel that is easy to mount. When on your RV, you need to mount it on the side or on top of the vehicle without stress. Check if it has a frame that can hold it for convenience and to ensure that nobody steals your solar panel.

Weatherproof

You may be out on an RV adventure and suddenly it starts to rain, its comforting if your solar panels are weather-resistant. Weather patterns are unpredictable and you can be caught unawares. Check to see if the solar panels are weather proof. The resistance includes things like dust, water and snow. At least ensure your panel is waterproof as it makes it more durable and spills or rain will not affect its performance.

Ammeter

An ammeter keeps track of your energy. It tells you how much is converted from solarpower to electrical. Most people can’t read it and consider it more or less as an option.  However, it’s an important consideration when buying a portable solar panel.  Ammeter enables you to know how much energy you have left at night during which the solar panel is not charging.

Reliability and efficiency

Check the performance and ensure it’s a clean power source. Choose a panel that converts more solar power to electricity.  The efficiency depends on size in proportion to power output. RV panels are smaller than home panels. Choose a more efficient option to ensure your RV has enough power for appliances.

How Much Solar Power Do I Need For RV?

Nowadays, campers and TV travelers are taking advantage of the solar revolution to solve their power problems. It’s not just that solar panels are green, very efficient. This feature makes it a viable option as it eliminates your need for traditional power sources like electricity, gasoline or diesel-powered generators. 

RV solar panels harness solar energy with the help of the several photovoltaic cells producing a DC. The direct current (DC) is stored in your RV 12 volt batteries.  Your RV onboard inverter turns the DC into AC and your appliances can charge or run on it.

Determine your power needs by taking into account the number of panels, wattage, solar panels size and your energy storage for the energy generated.

Determining your solar power need

Start by finding out your required wattage to run your appliances and RV on a good day. This ensures that there will be no power shortage or current. Calculate the wattage by appliance and total them to know your average usage. You get the information printed on your appliances alongside the specs. 

Total up the watts you need to run y all your appliances in a single day, per appliance per hour. For example, if you watch TV for 2-hours, total the wattage for two hours. The calculation gives you an accurate assessment of your power needs.  Factor in your battery bank capacity, size, wattage requirement and type of your photovoltaic cells. 

Real world testing

Proceed to do a real-world test to factor in any hiccups o you may face when on an off-grid RV vacation. Choose a location close to electricity backup power. If you pick a backyard, disconnect power to the RV completely as you get real world test results. Try not to conserve power, do things normally. 

Use a battery meter to monitor your battery discharge levels.  Ensure the acid levels don’t dip below 50% as it affects battery life and can cause damage.  Use the power consumption to know your wattage needs.  Do this by calculating your battery amp hours. 

For example, if you have a 240 amp hour battery bank at the start and after the field test you find 120 amp hours. It means you used up half the stored current or your usage is 120 amp hours per day.  Watch the battery level toensure it doesn’t dip under 50% to avoid draining the battery completely.

Convert watts to amps hours

Use the simple formula amp-hours x voltage = watt hours. You can get amp hours by manipulating the same equation.  All batteries have their voltage printed on them and you get the wattage from your wattage estimate consumption in a given hour then use the equation.

For example, you leave a 60-watt lightbulb on for 4 hours, it means it consumes 4 x 60 = 240 watt hours. If you connect it to a 12 volt battery, then your amp hours is 240 /12 = 120 amp hours.  Divide 120/4 = 30 amps for every hour of usage.  Do the same for all appliances to get your solar power need.

Do You Need a Battery, An Inverter, Or a Charge Controller?

Battery and inverter

The battery, inverter and charge controller are vital in solar power. The battery stores harnessed solar power while the inverter converts that stored DC current to AC current which can run your appliances.  Under ideal conditions, a 12 volt battery can store an upward of 300 watts giving you around 100 amp hours. 

Therefore, if you have two 12V batteries or four 6V batteries, you can store 200-250 amp hours which is sufficient to support 600 watts of solar panels.  To run a 120VAC appliances you will need an inverter to invert DC power to the AC power. Consequently, you need a larger battery bank than just one 12V battery you get on most TVs. 

Charge controller

Transition from DC to AC requires an inverter system. The charge controller regulates power that goes into your batteries to prevent overcharging or damage.   Common charge controllers are PWM and MPPT with the latter being the most modern and best in the market for charging batteries. MPPT are efficient and converts excess voltage to amperage.

Most panels deliver excess volts than you need to charge your batteries, this increases amperage which means it takes a short time to fully charge your batteries. This is a good feature if you are off-grid and gives you efficient battery management.

What Is The Difference Between Solar Panel Types (Poly Vs. Mono)?

Monocrystalline crystal solar panels

Are the premium solar product with sleeker aesthetics and higher efficiency. Monocrystalline panels use purer silicon crystal which means that one cell has a single crystal, leaving ample space for electrons to move generating more power output.

Therefore, expect a monocrystalline solar panel to produce enough power to power both your RV and accompanying devices or appliances. Furthermore, the purer nature of silicon crystals makes them more durable. However, these solar panels are very expensive.  Usually, a single panel has 60 to 72 solar cells, depending on the size of the solar panel.

The power efficiency is 17-22% and needs less space to reach power capacity which gives you a higher power output than polycrystalline panels. In simple terms, you require less monocrystalline panels generate the power multiple polycrystalline panels will generate under similar conditions.

Polycrystalline solar panels

Polycrystalline panels have lower efficiency in comparison to monocrystalline panels.  However, it has many crystals meaning there is less freedom of movement for electrons to generate flow of electricity which accounts for the lower efficiency feature. 

They are made of a combination of materials one being silicon. The solar panels are identified by their bluish exterior. Remember, monocrystalline panels have black exterior.  The fact that it combines different materials means it gives you less power in comparison to monocrystalline panels. Besides, polycrystalline panels are less costly. 

Just like monocrystalline panels, a single solar panel has 60 to 72 solar cells. It has an efficiency rating of 15 -17%. Technology is bridging the efficiency gap with manufacturers making 240-300 watt panels.

How Do You Hook Up Solar Panels to Charge an RV Battery?

Set up the solar panels on the roof to generate solar power. Hook your better to the charge controller. You can use the tray cable to connect them. Ensure you put the wire into the battery terminal of your charge controller. Match the respective + and - of both charge controller and battery.

Tightly screw any exposed tire inside the controller terminal then screw the battery rings to your battery.

Connect the solar panel to the charge controller. You can first connect an adapter kit to the solar panel first. Repeat the same process by matching the + and - signs off the lead solar panels with that of the + and - signs of the charge controller respectively.

CAUTION: inserting it incorrectly reverses polarity and can short your system giving your unwanted damages to both charge controller and solar panels.

Hook up the inverter to your battery using those battery ring cables. Also, match the + to + and - to -.

Charging two RV batteries

Most solar charge controllers only let you charge one battery. So, if you have two batteries, you need a better system that can charge the extra battery. A few charge controllers have default option of charging two battery banks.  However, in this case, the battery banks charge separately using the same solar panels and charge controller.

So how do you charge 2 RV batteries?

Get a dual bank charge controller. There are two discrete battery connection terminals on either side of your solar array connection. Start with one battery then add the next later.  The first battery receives full charge then the second battery starts to charge.  The solar charge controller mainly prevents your solar panel from overcharging the battery.  Consequently, the dual battery bank has two independent batteries discharging different functions.

Can I Connect a Solar Panel Directly to a Battery?

You can but it’s not advisable because it’s risky. As much as it can work, you will be putting out more power into the battery than

Can I Use the Electrical Outlets in My RV If I Have Solar Panels?

Yes. But first, you must ensure the electrical connections are done properly. By now you know how much wattage you need or amp hours to power your electrical appliances. Start by sizing your batteries to suit your electrical demands. Connect your solar batteries to your RV electrical system and install the inverter to ensure your RV electrical outlet uses the converted AC current.

RV solar panels power everything from lights, fans, TVs, mobile devices, and electrical appliances such as microwaves, electric kettles and blenders among others. You enjoy free power and only purchase vital accessories like fuses, cables, batteries and mounting hardware.

Besides, solar panels need minimal maintenance cost which saves you money and time. It only requires only occasional dusting.  However, regularly recharge your batteries to extend their life.  However, you need the right RV solar panels to ensure that your battery life is extended and you enjoy all these benefits. Plus, you can comfortably plug into your RV electrical outlet to run any appliance.

How Long Will It Take to Charge My RV Battery With Solar Panels?

It takes 5-8 hours to fully charge your RV battery if you are using a 12V battery if fully discharged. The time depends on your battery sizeand the wattage of your panels. Plus, environmental factors play a big role.  On a bright sunny day, it takes less time to fully charge your RV batteries. However, on a cloudy or rainy day, it takes considerably longer to charge your battery.

Other factors include the angle of your solar panels and whether they are pointing away from the sunlight direction.  Therefore, rotate your solar panels towards the sun to increase power output and decrease RV battery recharge time.

Charging time isn’t an issue if your RV batteries are constantly hooked as they will not drop below 50%. The moment they draw near the 50%-mark, recharging begins. Therefore, it will take a shorter time to fully charge and you will be enjoying full power as long as weather conditions are ideal.

Where Is the Best Place to Install the Solar Panels?

Position, orientation and placement are vital when dealing with solar panels.  It doesn’t make sense to place the panels horizontally. Remember, you want value for the investment which means placing the solar panels correctly is important.  Most often, solar panels are placed ontop the RV for good reasons.

The aim is to harness maximum solar power, and it makes sense to mount them on top of your RV than on the side. Nevertheless, some people also mount them to the side of their RVs. Consider your RV setting and how much energy you need, then pick a position that gives you maximum sunlight. 

Orientation and positioningdepend on roof strength, tilt and weather conditions of the area. Obstructions like snowing and hail bring shading.  As much as roof mounting is popular, it’s impractical in some RVs due to pace limitations or tilt angle. In rare cases ground mounting is the only viable option.

Shading affects the solar power you harvest, so understand positioning and orientation factors before making the decision. If you have trouble setting up your solar panels or positioning them right, contact professionals for assistance. The placement areas should be ideal and enables you to maximize solar harnessing to give your RV more power

Do Solar Panels Work at All When It’s Cloudy?

Yes. However, the panels harness less power that it does on a bright sunny day. Solar panels are indeed less effective at night and cloudy days, but still give you some energy.  Expect less than the rated capacity and the power output largely depends on whether the clouds are dense or not. Furthermore, power output depends on the design of the solar panels.

Some panels can harness power from blue and red wavelengths, meaning they generate power even on cloudy conditions.  On a cloudy day, the panels have a power output of 10-25% of their normal output on a good sunny day. Obviously, this is much less than direct sunlight periods its better than nothing.
