So - I have a location where I can fit either of these solar panels (but not anything larger), but just wondering, why is there a big discrepencey between the two specs of these units? They are approximately the same size - I am a newb on this stuff, so and help is appreciated - but I always though size was important in solar panels.
This HQRP one is (47x21 inches): "80 watts" - Maximum Power Voltage: 17.6V; Open Circuit Voltage: 21.8V; Maximum Power Current: 4.83A - [ame="http://www.amazon.com/HQRP-Mono-crystalline-Anodized-Aluminum-Coaster/dp/B002OSAB28/ref=sr_1_21?ie=UTF8&s=hi&qid=1283881003&sr=8-21"]CLICK HERE[/ame]
and this Bruton one is (42x15 inches): # "15 Watts" - Output Voltage: 12V; Maximum Power Current: 1000mA: [ame="http://www.amazon.com/Brunton-Solarflat-15-Solar-Amorphous-Protection/dp/B001NG0WVW/ref=sr_1_10?ie=UTF8&s=electronics&qid=1283881441&sr=8-10"]CLICK HERE[/ame]
So - why the big different in specs?
I am looking to run a Engel MT040. I have two small (space issues) 35AH batteries that I want to keep charged via solar.
Thanks for your help!
