12v Solar Panel Charger

This is a simple 5 watt solar panel that I am hooking up to a cigarette plug to charge my batteries on my truck that I don't drive much. The panel puts out 24 volts. How do I convert it to 12 volts?

Converters are shown in the link below.

However, most solar panels are 12 volts. I am thinking your have two panels connected in series to get 24 volts. It that is the case perhaps there is a way to wire them parallel instead of...

Basically, I wanted to make a "portable charger". I was planning to connect a solar panel to an English socket, and from there be able to plug any charger, a phone charger for example, and charge my phone from the solar energy.
...

you need to understand that house wiring is at 220 volts AC, and solar panels put out low voltage DC.

It's difficult and expensive to convert low voltage DC to 220 volts AC. You are better off not trying, specially with your limited...

This is under the best sunlight conditions, the solar panel is rated at 1.8W and the battery pack is 300W. The solar panel reads that it is a "trickle charger". My question is how long it would take such solar panel to recharge a completely

If the battery wouldn't self-discharge, it would be:

300W/1.8W = 166 h 40 m

With 12 hours of sunlight per day, it will take about 14 days.

However, since all rechargeable batteries self-discharge over...

I am trying to find a way to power my sirius sattelite boom box using solar. I was thinking of using the 12v 5 watt panel offered on harborfreight.com (ITEM 41144-0VGA) with my boombox (SUBX2.) The only problem that I see is the input voltage on...

You would be best served by using the solar panel to charge up some NiCad batteries instead of directly connecting the panel to a boom box. (unless you need this for a demo on solar power)

The solar panel is not going to output a stead

I have a 12v , 13 watt solar panel - here is a link to the page http://www.batteryjunction.com/12vbrsoge s.html - I want to use this solar panel to hook up AC adapters. IM not sure what to do and how to use the solar panel. I want to be able to use a

The solar panel has a 12 volt output with only 13 watts of power at 700mA.

This is very useful for charging low voltage devices directly, such as a radio, batteries or a GPS unit.

It is not effective to attach an inverter to

Can anyone tell me what wattage I need. I done some calculations which i dont know is correct but I got 12 watts. Can anyone help

Most batteries are designed for a 10 hour charge rate. In that sense 12 W is right for a 12 volt 10 ah battery. The catch is that the panels are usually specified for peak wattage. Since you can expect only about 6 hrs of sunlight even on a clear day
