Flat solar panel performance today in Quartzsite

Watching a couple of playoff games on Sunday, I got 42 AH on 130W tilted. Compared to 505W flat & 105AH; I get 55% more power tilted.

42AH is a major power use for me. Wouldn't know where to put 105AH.

Can you elaborate or point to a thread which elaborates? Thanks!

150 watts, portable, PWM controller, aimed at the sun two to three times a day, set at 14.4 V, 13.8V showing at the terminals, started up at 10:30 AM on Friday, showing 8.3 amps charge rate, aimed at the sun, Plomosa campground, Quartzsite, AZ. One 150 amp hour Telecom AGM battery, down perhaps 30-35 amps from full charge.

I've no idea when it stops charging, I do know that I got a full charge, even with all the high clouds all day on Saturday. By 9pm at night, Saturday night, I was showing 12.74V, down from 12.84V when fully charged.

Now that I am home again, I will top charge it again for about 3 to 4 hours at 14.40V for storage purposes and to prevent sulfation.


I've seen 8.9 amps out of it in mid June, along the Madison River, Raynolds Pass Road, MT, 8 miles from the Continental Divide there, laid flat on astroturf, battery in same state of charge and plugged in at 11 AM in the morning to start charging.

That explains it, thanks.

For some reason I have been unable to post a reply all day to this particular thread.

I'm now sure that my 60 AH was highly overstated. I calibrated my meters today. I'm not convinced they are going to give me great accuracy though.

16.6A panels * 3.69 kwh/mm/today total = 61 ah
