Re: Solar anyone?
Some quick ballpark calculations (using conservative safety error margins):
Flooded lead acid batteries self-discharge at about 1% capacity per day.
A 200AmpHours battery bank has a discharge capacity of 10amps (200AH/20H).
That equates to a self-discharge rate of 1% = 0.1amps, let's double that for a worst case scenario during the hot summer = 0.2 amps discharge.
If is only sunny every other day, 0.2amps x 2 = 0.4 amps needed.
If You only get 8 hours of sun on those days, 0.4 x 3 = 1.2amps needed.
So You would need a charge rate of about 1.2amps during those sunny hours to fully counter balance the self-discharge rate.
The panel You posted is able to provide 2 amps, so it is more than enough.
I would be more concerned with the cart left outside, the hot sun while good for the solar panel, it is not so good on the rubber tires, vinyl seats, etc....
Depending on the area you leave the cart, You may want to consider keeping the cart under cover/roof and place only the solar panel where it gets the most sun.
You can always run a cable from the solar panel to the cart.
