HiTech quote:" I am ok living with the battery only being charged up to 90 percent DAILY for a week or 10 days."

A 68 watt panel can supply maximum 4.5 amps (good sun angle) for each hour. With an 85AH battery a discharge to 70%soc would represent approx. 60 AH, or 17 amps to get back to 90%soc.
You may have to limit any daily usage to 25% of capacity (maybe less) to be able to even reach 90%soc on a daily basis. I would hope your experiment might show more than the 10AH you expect. Also: any cloudy days in that 7 to 10 day period may mean needed generator time.
