15 Watt Solar Charger

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

My 5 watt solar panel car battery charger manual states that charge controller is not necessary for panels under 15 watts. I'm trying to understand the physics of why that's the case. Even if my panel is only putting out say 15 volts at 350mA...

A typical lead-acid battery can safely be "trickle charged" at C/100 rate, where C is the capacity (if you are talking car battery, that is about 50Amp-hours typical). C/100 for a 50Ah battery is 500mA, so 350mA won't hurt it. The...

I'm looking for an affordable way to charge a large 12v battery with solar power, but with a float so I don't boil it over and ruin the battery or worse. A year ago my brother and I nearly burned his house down with a tiny 0.5 watt solar charger that
