I have questions about panels. I have a Flare 2010-2011 fall,winter catalog. Et,Kyocera,Sharp and CDT Solar are the brands in in the catalog.I'm sre prices have changed,hopefully they went down some. 80 watt NE-80EJE Sharp is priced at $360. ETSolar 85 watt is $295. Kyocera 85 wat is 4449. Is there that much difference and what type of power bank would I need for a 80 watt panel? Any of these from China?And does it matter?
