The only thing you need to know is your consumption
.. this is the be all and end all of charging
... 95% of your consumption
is your fridge setup, underway, 75% is your auto pilot.
If you dont have a battery monitor
, install one of these first...then you will be able to get a very clear idea of what you need...there is simply no substitute for knowing your boat.
for example, I run a single
fridge, and comsume approx 45aH/day at anchor
.. one single
panel that i throw onto the boom, or on the foredeck and a MPPT charger
will maintain this in mostly sunshine without ever charging
... in one case, 3 weeks straight in Georgetown
If you wish to run offshore
without charging then you will likely need a wind generator
to supplement any solar

Batteries: My new Leopard
has: 2 x 220ah deep cycle lead acid, 2 x 100ah lead acid
Inverter/chargers: Standard Trace 2kw/100amp
Question: Given the size of the battery
bank, what would be the correct wattage of solar panels
to keep the current
batteries topped off? I don't know my watt usage yet but there must be a maximum amount of watts my 2000W/ 12V, 120A inverter charger
I almost have this down but would greatly appreciate your answers.
