15 Watt 12 Volt Solar Panel

I am trying to build a self sufficient system that can be ran about 12 hours a day.

The system uses approx. 15 amps 12 volts as long as it is on.
I am planning on hooking it to a 12 volt deep cycle battery with a 12 volt 15 watt

You don't say where you are, that will affect the number of sun hours, and therefore how much power you can generate a day. Let's assume an average of 5 sun hours, which is different from the hours of sunlight, it is the equivalent of standard...

Amorphous crystal solar panel provides superior performance in bright sun and in partial shade. Use this solar panel to power an appliance, light ...

i have tried to hook them up to my regulator on parrallel but they still display the same watts...how do i increase? or is it just reading it wrong?

You would wire the outputs in parallel. That would still give you the 12 volts but add the current capability of each. Make sure you get positive to positive and negative to negative when you wire them together. Check them with a meter if necessar

How long does it take a 15 watt, 12 volt solar panel to charge a 12 volt R.V. battery?

Most solar panels have something called a charge controller on them. This prevents electricity from going backwards from the battery to the panel. Solar panels are rated at 12V but they do put out a little more than that during full sun...

I am charging two ....6volt batteries connected to give me 12 volts 450 amp hours I would like to connect the 2 and possibly more panels togeather so the batteries will charge faster is all this possible if the panels are all 12 volt but different...

Connect them in parellel. This will give you 12vdc at 115 watts and around 9.5 amps.

I have 2 solar panels one is 15 watts 12 volts 1.2 amps or -
The other is 50 watts 12 volts 2.6 amps or-
Can I ...and what is the best way to hook them togeather to increase my amps being put back to my battery ?? I would be hooking

The answer is that the two panels should be put in parallel. The voltage out will drop to the voltage of the lower panel, but you should get most of the power, if the panels aren't too badly mismatched.

I would try to get a multimeter

The battery will be charge by a 15 watt solar panel and the bulbs will be routed to an 100 watt inverter
The light would be on at night
most days we get more than 4 hours of daylight ( I plan to add a 400 watt wind generator in the...

How many hours a day does the sun shine?
Do you know the efficiency of the inverter?

Just to make the math easy, I'll assume that you'll need 50watts input to the inverter to power the 38W light, probably a little too high, but
