So I did some searching online to figure out how to recharge my marine 12 volt battery with a solar panel.
I'm confused.
Basically I use a battery to run my pump for nutrients. It runs 3 minutes, 8 times per day. There are two hours in between waterings.
Trying to figure out what size panel to recharge this battery.
A lot of them seem to just provide enough juice to keep an idle battery from discharging.
I want to actually charge mine.

My pump is AC but I might get a DC so I don't have to use an inverter from the battery.
Pump specs:
Material metal, aluminum
Power Source ac
Voltage 115 volts
Wattage 104 watts
Amperage Capacity 0.9 A

I will return with battery specs shortly.
