3×2 Solar cells

I received 42 3×2 solar cells today. This is enough to construct a decent sized panel of around 30 watts. The fun part will be soldering all 42 in series. I know I say 60 amps in the video ( or close to it) but that was assuming I wire it all in series/parallel….and I doubt ill do it…wouldnt that be 1260 watts?
Try eBay for loose cells….
I purchased my solar cells from solar-deals(.)com. 5″ x 5″ solar cells.
.5V @ 1.4A * 24 in series = 12V *1.4A = 16.8W
Voltages add in series and current adds in parallel.
You would have to parallel 43 strands of 24 to get 12V * 60.2A = 722.4W. Of course it’s not that easy as you’d need blocking diodes to prevent “shaded” cells from drawing current.

I just got another 50 pcs of 5″ x 5″ KPE monocrystalline solar cells for $169! Offer is going on until Sunday, July 12th, 2009! Solar-Deals(.)com
poss + is on the bottom of the cell, and neg is on the top of the cell, check out my web site
at solarcells101 for solar cells and soldering instructions.
Aren’t Blue side negative and the back side positive?
Sorry buddy, this is miss info on everything. You should redo this video !
