Pulled the trigger on a 30 watt Powerfilm foldable solar charger.

:archaeolo Yea, CWK, remember that any of these panels are only 80 %, efficient at FULL SUN--




And your flexible panel, has diff. outputs from each segment, but overall--whats the problem???

None of the solar panels will work very good on a cloudy day and your MAX output, will be 23 volts +++

Like (762) says, thats with no load, but you're probably at 40/50% effeciency, on the cloudy days and once the sun gets down to afternoon exposure--you get down to 20/30%, if that much

I look forward to your further posts

I'm 500 miles from home now and I'm "surfing"

Jimbo, you were right about the power drop when you pass your hand over the panel. But before I could do that, an acrobatic paraglider got the jump on me. Consequently, she was hot! And yes my voltage dropped as I glanced over to see me wife's hands on hips staring at me, staring at the glider chick....

Alright anyways, I think I get it. With no load attached, the voltage will always run higher than if a peripheral is connected. Which in turn will drop the free unrestrained voltage down. And when a load is connected, will the equation render a accurate measurement in watts right?

Volts x Amps= watts

I am impressed with the 19.7 volt output considering the weather conditions and look forward to seeing what the averages will be. I wish I had measured it before and after the charge controller, next time. I think I might have get the Sunforce 60 watt panel next. The wife is going to love that one...:bigbossHL:

Don't be discouraged by all the what ifs...We purchased a 20 watt panel for my dad's trailer about 20 years ago (at a cost of $500 back then) and it was fine for topping up the battery to keep the incandescant 12 volt lights and the water-pump running on his Jayco travel trailer for 10 years.We didn't even think to use a charge controller back then and only boiled 1 battery dry.Charge something with the panel and enjoy it.

No pic of the glider chick? :bike_rider:

Since you asked... Of course! She actually almost high-fived a standing dude on one swooping pass unfortunately said dude was not me... At this juncture I was done looking at the solar charger.

Una mas... Unfortunately I didn't get her telephone number...Maybe I need to step up my game...Wait, I'm married...Just forget it....I give up. Maybe I could get that seagull's number...:REOutShootinghunter

unk03: Well, CWK, since you're becoming practiced at SUN effects

Una mas... Unfortunately I didn't get her telephone number...Maybe I need to step up my game...Wait, I'm married...Just forget it....I give up. Maybe I could get that seagull's number...:REOutShootinghunter

Just start practicing your SUN/MIRROR messaging and you can do all of it SILENTLY !!!
