Car Battery Solar

I have a 10 watt solar panel. I want to charge a car battery with it. What other equipment or peripherals I would need?
Thank you

That panel is too small to charge a car battery. You won't get more than half an amp out of it.

If you connect a solar panel directly to a car battery, it will eventually overcharge the battery and damage it. That's why you need to use a ...

Is it reasonable for an avg solar powered (30cm x 10cm) car battery charger to have an output of 661W over the span of 1 day?

Its the answer I got for my assignment and I'm not sure whether that is correct.
when i use my...

In reality it totally depends on the output of your solar panel. It must be cleaned weekly. 6.61 watts per hour for 10 hours of sunlight equals 661 watts. Another terminology for your quantity is nearly 2/3 of a kilowatt hour per day. However when...

I'm trying to put something together in a rural region of the developing world. I have the solar panel and some car batteries. The goal is to be able to deliver 120vA for short periods.

You need to hook enough solar panels in series to give a voltage slightly higher than that delivered by the car batteries. I'll assume that they're 12 volt batteries. Connect the panels in series until the output is about 12.5 volts. Connect...

I want to install a solar trickle charger on my motor home but some state they only work if the 12V cigar lighter socket is permanently live (ie, when the ignition is off) Is this true of ALL these chargers?

If you connect through the cigar lighter then yes it must be live.
These solar chargers also come with crocodile clips to attach direct to the battery.

I just bought a 1.8-Watt Solar Battery Maintainer because I only drive my car once per week and I have to get a new battery every 12-15 months. Can the 1.8-Watt Solar Battery Maintainer help keep my battery charged?

also check the water on the battery....a lot of ppl overlook this.

I've never seen any car with one in, but see a lot on sale.

My car battery is old, and I'm just thinking this might be a way to extend it's life.
Oops... my router went down for 20 mins... thumbs up for you all.

they work really good, i use one on my old car to keep the battery up in it,and it works really well,its always at a 100% charge when i go to drive it,and the good thing about is it wont over charge it,it even works on a cloudy day also,i have...
