[QUOTE="Ded Driver, post: 476242, member: 12692"] my 100W polycrystalline solar panel I have mounted on my roofrack cost me about $130 middle of last year. I measured this panel's open circuit output at 23V in full sun mid December. In researching monocrystalline vs polycrystalline, a bit of info I dug up indicated that mono generally has a higher efficiency overall, but the gap is closing with poly now getting closer in efficiency (manufacturer quality obviously has a big bearing on that but). Poly panels are cheaper to produce & an interesting fact is that apparently the poly maintains its efficiency better at elevated temperatures. Handy in WA in the summer when it gets the most use. Today around midday it was (still is) fully overcast & on/off drizzling rain, & with everything turned off but the DC-DC/Solar charger running, I was watching the voltmeter on the solar panel input. It was fluctuating from just over 7V to just over 15V & occasionally hitting 18V In 4hrs the Aux battery has risen from 12.9V to 13.2V so im pretty happy with its performance [/QUOTE]
