I know the basics of Watt use and how to calculate watts( AHx Volts= Watts and Watts x Time= Amount required.I am thinking of a solar panel system that is 500 W with a 55AH Battery. This system is a decent price BUT HEAVY( again why its affordable) My question is :Can I use a 25AH 2V DC Battery Bank (4 Batteries) and hook it up to my 500 W solar panel to charge the batteries?And if there is enough sun how long would it take?Would I have to charge each battery individually or can I charge the whole bank with just that 500 W solar panel?Im trying to find the best system with a decent price and less building needed. Of course there will be comprimises. For example: The sola system I saw was the Wagan( Cube type) panel from Home Depot for under $200, and 25 AH 2 V DC Battery 4 pack for $00 on OKorder. Just wondering if 500 W would be enough for this endeavor considering that this type of Battery is 500 Watts per battery and the system is 500 watts ( which can be hooked up to more panels)
