A steel stand keeps it up and is designed to fold out.

What solar panel do i need to charge a 12v battery.

The big folding panels have about 80 to 20 watts. Solar battery charging basics. People globally have gone solar since it helps reduce the ever rising power utility bills. Divide the wattage of the solar panel by the voltage of the battery to get the number of amps your charge connector needs to handle.

A 24v panel may give as low as 18 20v depending upon sunlight but you should a voltage regulator in between. Like the acopower vs20ak that includes the cables we need to connect it to the renogy solar panels and the 12v battery. These solar panels are equipped with a solar controller to charge a single 12v battery. Then run wires from the battery to the charge connector making sure to match the positive and negative poles.

If you need panels that are portable a flexible product is the best choice. Let s say you want to compute for the average charging time of a system with a 12v battery with 50 ah capacity and a 15 watts solar panel. The first thing you have to do it to compute for the ampere rating of the solar panel by following the equation below. It comes with an sae connector for pre wired 2 pin sockets found on some rv brands.

In order to charge a 12 volt battery efficiently you ll need a solar panel that produces 12 volts. If you re concerned about performance and speed invest in a 16 volt solar panel instead.
