    there one you said you found on ebay for 40 bucks whats the wattage and voltage of that pannel compaird to the one you was shoing for 150 I would almost guess that the one for 150 could be like a 150 to 200 watt witch if you were to buy built wold cost you about 700 bucks so if you can buld one you self and be as good as the professional ones then you could almost build 3 for the price of one build buy some one else and thats what I like to do build my own would save me a lot of money.

    The one I bought off eBay for $40.00 was a 6 watt solar panel. The one I was aiming for was the same wattage (6 watts).

    Most PV Cells are rated at .5 volts each, so that’s why I only needed 36 solar cells no matter what the size of the cells are since each one is rated at .5 volts. However, what is reduced is the amperage output. The amperage output compared to an evergreen 3×6 solar cell is fairly low.

    Evergreen 3×6 Solar cells = 3.5 Amps
    These small solar cells = 0.30 Amps

    It’s usually setup like this:

    The larger the solar cell, the greater the amperage, but the voltage will usually always be only .5 volts.

    So no matter what, I was going to end up paying a lot more to build one myself. A lot of people don’t understand that solar energy isn’t as cheap as many of these articles state they are unless you can find resources where you can receive discounts, or even receive the cells for free. Some use broken solar cells like Virlusun, which you can find cheap.

    O yea I know that I have two solar pannels they are 18 bolt and are only 10 watt got them for 25 bucks for a lot of 5 at a goverment auction. all solar cell big or large produce about .5 volts. some are less some are more +or_ .05 and amperage varrys depending on the pannel if you want current I know you link in parrellel and if you want voltage you go in Series and you do both for voltage and amperage and I know you take the amps x the voltage to get wattage.

    so you can talk tech to me if you like I pretty sure I will under stand lol. I was a telephone computer repair tech in the marines for 5 years and I love working on electronic and building stuff and love trains. and want so much to tell the power company were they can stick it lol

  6. #6 by RobertSmith3 at January 13th, 2010

    Great, it just looked like in your message that you stated with the small panel I was creating, I could produce 150 to 200 watts from that?

    What type of solar cells are you using, as I don’t believe they offer that technology in the US yet? lol The max wattage I can see coming out of a frame that small is anywhere from 5 – 10 watts, but I’m just estimating there.

    Either way, it would still come out cheaper to buy the professionally made panel off eBay in this case.

    sorry for the confusion the small ones I have are only 10 watts and produce 18 volts in full sunlight. I saw on the video you was talking about a 36 cell pannel and I was thinking you was using the full size cells that are like 4×4 inch. and I was looking at the figures you had and thats were I got the cost so I guess I thought you was bulding a large on with 36 cells to build like a 150 to 200watt for like 150 bucks give or take a few bucks

  8. #8 by mccunecp at January 13th, 2010

    so you are talking about the small one I guess you are using 36 broken peices to make that pannel but its cool but either way its cool what your doing. I was thinking you was talkng about building one of the large pannes for that price and I was like heck that is cheep lol because one of the 36 cell 150 to 200watt pannels are like 600 bucks or more. not cheap almost 4 bucks or more per watt.

  9. #9 by RobertSmith3 at January 13th, 2010

    I planned on using similar cells that the professional panel used, which are regular solar cells, just smaller. So they don’t have to be broken at all to use 36 solar cells, just cut down to size so that you have enough to produce 18 volts since no matter the size of the cell, each one will produce .5 volts. It’s hard to see from far away, but that 6 watt professional panel I have in the video is made up of 36 small solar cells.

  10. #10 by mccunecp at January 13th, 2010

    ok got yea its cool. but using th same ideas and steps you show there you can do the same to make the larger pannels I wonder how much it would cost me to build a larger one finding uv glass will probably be the hardest thing. and I have found even with my small pannels I can get them to push 20 watts if I use a fenell lenz like those found one big screan tv. liek the projection ones. or even a mirror. getting free power from the sun is exciting.

    as an engineer, i see a lot of wasted material on that frame, that could have been used to cut down on overhead.

  12. #12 by RobertSmith3 at January 13th, 2010

    Yeah I agree, however, it’s still a decent simple frame that gets the job done, and since no one else seems to be selling the frames I had no room to complain lol.

    thanks for making these vids. I always wondered about pricing. Seems like you’d only save money if you did this thing large scale.

  14. #14 by steveman223 at January 15th, 2010

    looks like a sturdy well built frame to me. yah it could have been built cheap and would definilty show in quality

    This dude is the best. I watched his video’s on how to build a solar panel and it’s excellent. Definitely impressed!
