RV Solar Battery Chargers: The Basics

What is a solar charger?

In layman’s terms, a RV solar battery charger is a purpose-design charger that could charge battery banks of recreational vehicles using solar energy. Packing built-in solar panels, solar battery chargers for RV tend to take moments to set up and put away. 

How does it work?

When sunlight touches the solar panels of solar battery chargers, there would be a contact between photons (sunlight) and electrons (solar cells) which generate electricity. Assuming that the connection is good, the electricity that the solar battery chargers generate is going to move into batteries.

At that point, people can do whatever they want with the electricity they have in the batteries of their vehicles. In most of the cases, an inverter is necessary to change electricity from direct current (DC) to alternating current (AC). 

Benefits of RV solar chargers

  • Independence: Unlike other types of chargers for recreational vehicles, solar battery chargers allow camper owners to recharge battery banks anywhere and anytime during the day. That is a big plus for those with busy schedules. 
  • Longevity: Since RV solar battery chargers produce pure electricity, they optimize the lifespan of batteries in quite a few conditions. By using solar battery chargers, RVers could extend the replacement interval of batteries in the battery bank with relative ease. 
  • Quiet: In the course of operation, solar battery chargers stay silent so they don’t disturb people in the surrounding. You happen to have sensitive hearing and wish to keep the level of noise down? Then it’s strongly recommended that you grab a solar battery charger for your RV. 
  • Expense: To work, all solar battery chargers need is sunlight. Hence, with these chargers onboard, people have an easy time powering appliances and cutting utility bills at the same time. 
  • Environment: Solar battery chargers for RV release nothing as they generate electricity for the batteries. Because of that, the chargers receive a shower of praise from eco-conscious RV owners. 

Types of RV solar battery chargers 

Today’s market contains various solar battery chargers for recreational vehicles but it’s possible to split models into three types: monocrystalline, polycrystalline and amorphous

  • Monocrystalline Solar Chargers: Capable of generating electricity even if the availability of sunlight is less than ideal, monocrystalline solar chargers work well in numerous situations. In addition to that, models of the type boast top-notch endurance so they last a long time in use. That being said, monocrystalline solar chargers cost a lot so RVing enthusiasts have to take the shopping budget into account. 
  • Polycrystalline Solar Chargers: Reaching the market at reasonable prices, polycrystalline solar chargers prove popular among RV owners with tight wallets. Featuring a compact profile, models of the type only occupy a bit of space in the interior of rigs too. Still, in exchange, the efficiency of polycrystalline solar chargers is mediocre so the flow of electricity is not exactly impressive.   
  • Amorphous Solar Chargers: Also known as thin-film solar chargers, amorphous solar chargers don’t have many competitors in the market in terms of affordability. Furthermore, with fantastic flexibility, models of the type give RVers an assortment of charging options. For drawbacks, amorphous solar chargers take up a large amount of space inside recreational vehicles.
