I usually buy HQST panels but these have a good rating and are 8 dollars cheaper per panel so I thought I'd take a chance.
Generally you use something called a solar regulator to connect panels to a battery.. they are inexpensive for a smallish setup..
I would NOT get a gel cell battery. I would get a 12V 100Ah LiFePO4
The LiFePO4 will have a much longer service life and they are NOT the same as the batteries in EVs ... I wouldn't have those burst-into-flames things in my home :-/
I recommend these, about 270.00 after the coupon and free ship.
One thing to remember though, do NOT charge a LiFePO4 if its temperature drops below freezing!!
Those panels are ridiculously cheap. When I first got into solar over 20 years ago they were running $5 a watt for cheap ones. lol
