RV Solar Battery Charger: Let Sun Power Charge Your RV Battery

Solar panels aren’t just for your home or business anymore.  Now with the right charge controller you can use them as an RV solarRenogy 100W Solar Panel Bundle Kit View battery charger whether you’re going off the grid, going green, or just like the idea of convenient and reliable low maintenance charging.

If you haven’t checked lately, solar panels and their accessories have dropped in price to the point where you can get a high powered solar panel and charge controller for a value price.

Why would you want to use a solar panel to charge your RV battery?  Let’s say your parking for days in a beautiful location that just happens to be without AC power (aren’t they all?).  What are your options for keeping your 12V batteries fully charged until you need them again?  Start up your gas or diesel generator?  That seems loud, inefficient, and not very green.

Why not choose a silent, efficient, and green way to charge your battery that only requires sunlight?  Sun power is the future, but fortunately you don’t have to wait for the future to charge your battery using the sun today.

Okay, it sounds like a good idea, but which RV solar battery charger should you buy?  The first thing you need to know is that a solar panel by itself will not safely do the job of charging your battery.  Solar panels need a charge controller that can regulate the current produced by the panel so that it provides the right voltage to your battery and doesn’t overcharge your battery.

Next, you need to think about solar panel wattage or how much power is produced by the panel.  It’s common to use solar power to trickle charge your battery mainly because most portable solar systems only produce from 5 to 30 watts of power and take a long time to charge a battery.  If you get a larger system the tradeoff is cost.  The more powerful the solar panels, the more expensive they are.

Fortunately, the cost has come down and now it’s reasonable to buy even a 100W panel and charge controller.  Why would you do that?  Do you really need that amount of power just to trickle charge a battery?  No you don’t need it for trickle charging, but think of what else you might use it for.

Higher wattage solar panels give you options.  First, they charge your battery more quickly saving you time.  You can use them to charge multiple batteries or produce power for lights and other equipment.

What is a good value in a solar panel and charge controller?  We recommend a 100W panel and charge controller to give you the most options and faster charging.  We recommend the Renogy 100W Solar Panel Bundle.  It is the perfect RV solar battery charger.
