Quote from: TheWire on August 09, 2010, 01:49:54 PMI'm looking at getting 4 40 watt PV panels from Sunelec specs are below and wiring them in series to a MPPT charge controller. Any thoughts as to these panels in this application, dealing with Sunelec or the quality of their products?Thank you.Model SUN-40Power (W) 40 WattsOpen Circuit Voltage (V) 21.90 VocShort Circuit Current (A) 2.54 IscMaximum Power Voltage (V) 17.50 VmpMaximum Power Current (A) 2.28 ImpDimensions 22" x 21 1/4" x 1 3/8"$120/ea

I'm curious if these are a quality or low end panel.As far as going with 4 small panels instead of single large panel, my challenge is mounting them. My cabin is in a wooded area and I expect I'm going to have to get creative with placing the panels to avoid shade. The small panels give me more mounting options and using 4 wired in series allows me to go 48V to my charge controller to cut down on the size of the wire.
Quote from: Tickhill on August 12, 2010, 03:58:42 AMThis may be an advertising scheme but I looked at sunelec.com today and the price glenn and I gave for our panels have gone up a .10 cents since yesterday and they are saying "PV Industry Shortage is Happening Now!"I wish I had done like glenn and went ahead and got 3 more. Just thought I would put that out there that there may be something to this and that $$ may start on the way back up.
