Hi all,
I've got a few questions about Solar performance and capacity. I don't see these specifically addressed on the forum already. I have seen the posts pointing to calculators for designing a system. I'm just trying to get a feel for battery performance.
Let's say I have two 6 volt golf cart batteries and one 100 watt solar panel.
1) I have a nice sunny day and a "full charge" in the batteries. I disconnect the solar panel. Could I expect my refrigerator to stay up (just on electric) for 24 hours? Longer? How long? Assume there is no other load on the batteries at all (for discussion purposes).
2) If it turns cloudy for a day or two, could I recharge the batteries via a generator or my vehicle wiring somehow? If so, would it be an easy connection, or would it have to be a "professional modification", wired up beforehand?
3) What is typical battery life - how often do you have to replace them?
4) Are two or four 6 volt batteries the preferred setup? Is there a better combination for everyday use?
As always, thanks for the valuable feedback!
