Re: How do I calculate my power needs?

Download "Battery, Load and generator calculator" by Bill Roosa here: Sailboat Solar Panel News---Information

It will give you something to experiment with.

You can also check your battery voltages after a day and see how the % you have drained the batteries. That will give you another estimate.
