The weather for our cruise in the North Channel of Lake Huron this year was excellent.  It was warmer and sunnier than last year.  Our Kyocera 85 watt solar panel performed very well.  The following are some statistics:

Days cruising:                                       22 days
Max power generation:                        40 amp-hours
Min power generation:                         13 amp-hours
Average power produced per day:  35 amp-hours

Average power consumed per day:      51 amp-hours

Our primary use of power was for the refrigerator/freezer.  We ran a power deficit each day of about 16 amp-hours at anchor but with our 360 amp-hour battery bank, this not a problem.  Moving on every 4 days or so gave the 75 amp alternator plenty of time to bring the batteries back up to charge.
