3×2 Solar cells

I received 42 3x2 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? ... solar panel cells 12volt DIY PHOTOVOLTAIC 12V

  1. Aren’t Blue side negative and the back side positive?

  2. 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.

  3. 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

  4. .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.

    FWIW, Jay

  5. I purchased my solar cells from solar-deals(.)com. 5″ x 5″ solar cells.

  6. Try eBay for loose cells….
