The panels are only 3 mm thick, making them easy to install. Perfect for RV's and boats, its flexible design can conform to almost any surface. The thin, lightweight design provides a low profile, which is aesthetically pleasing and more aerodynamic that traditional rigid solar modules.
Solar panels are made up of individual solar cells that convert sunlight into energy. That energy comes in the form of direct current (DC) electricity, which is used to charge and replenish your RV's batteries. Typically, several panels are joined together, creating a 'solar array.' What to look for.
How many volts does an RV solar charger take?
Many standard RV solar chargers don't produce enough voltage, only charging your RV battery to 13.7 volts—much less than the 14.4 volts required for a full charge. Without that complete charge, your “gas tank” won't be full. This means you won't be able to stay off-grid and run on battery power for as long as you would with full batteries.
How does voltage affect RV solar charging?
Think of voltage as “pump pressure”. Using our auto analogy, imagine you pull your car into the gas station to refill your gas tank. If the gas pump doesn't provide enough pressure, it will not completely fill your gas tank and you won't be able to drive as far next time. The same is true for RV solar charging.

How many watts a 12V battery does a solar panel use?
12V batteries are mostly used with 200 Watt (18V) solar panels. If you want to generate more than 50 amp-hours of power per day with direct sunlight, then a 12V 60Ah deep cycle battery or 75Ah normal battery would do the job. A 12V 100Ah battery will also suffice without a doubt.
Consider emerging features — options such as Bluetooth connectivity that will allow you to monitor and manage your controller remotely. While your RV batteries generally provide 12 volt DC power, many of the appliances you run in your RV require 120 volts AC (like in your home).
