How To Build A Solar Panel - Part 8

nice..!!!!!

Rob man what can i say thank you so much for your awesome video's your 1 mean solar making m f**ker! your guides are the best and your a real pro great teacher and from da heart thank you squillions ....love coming at ya from the united kingdom peace out solar man

Hey ya Rob,

Thanks for the vid. Do us a favour mate, gimme your addres so i can send ya a propper soldering iron - ;)).

Good job bud, watched all the vids, cheers.

Oh by the way, would it have been a better idea to solder the wires to the terminals being that the two mating surfaces are of different materials i.e. copper to aluminium = electrolisis.

Thanks

what solder u use ? 40pb and60sn ?

[parek142536]

Sorry, but you can't soldering

[martyjrjr]

i don't recomend plexiglas as it will frost or darken discolor use lexan.it looks the same but stays clear and is more scratch resistant and a little more money it's also harder to break

[frankt04]

Caution! Never use pixel glass only use Plexiglas...

[elmergamez]

How do you decided where it goes the positive and the negative conection?

The time has come for Free energy to be revealed ,But the big oil corporations don't want that technology revealed,Check this free energy magnet motor at LT-MAGNET-MOTORdotCOM ,Be part of the revolution!

[VFsplash]

Does it matter which end is negative and which is positive?

[DJControllerC]

Isn't it easier to use 4 rows or two rows of cells- so you dont have to run a long power wire?

Nice work Brah! Enjoy the vids thanks.

[typeXJuggernaut]

them round wire clips are meant to be crimped with the end of wire stripper your using the wrong end I would solder the wire direct only my choice

[soulshinobi]

Excuse me if it's been said, but using the crimp terminals on the ends of the wires is not only unnecessary, but offers poorer conductivity than than soldering the wires straight to the buses.

[Martintfre]

I like how he spends so much time and effort making things clean and professional looking...I am working on a similar project with out spending that attention to detail and well its butt ugly.

[rh001YT]

Robert: while the eyelet terminal soldered to the bus wire looked cool, I can tell you that from years of experience connectors crimped that the cheap tool will not be sound, will loosen up and may actually oxidize, causing voltage loss. Problem will be especially pronounced outdoors - some humidity will get into the rig, and the extreme heat will exacerbate. Solution: solder the lead out wire directly to bus wire. Solder is your friend.

[JimmyJacks00]

might wanna put silicon between the rails and the unit around your screw holes, this might be a stop that moisture can get in, btw, thanks for the videos!

[bulletjive]

Great video but what about blocking diodes? You should have at least one. I recomend one between each string. What was your total build cost? For a DIY this is THE best looking panel I've seen yet.

[CurrentlyDisconected]

great stuff man this tutorial has aswered most of my questions i belive i am ready to build.

[1978CamaroRedneck]

I been following these vids as a tutorial, im confused on what bus wire to hook the neg and pos wires to. Does it matter? In this vid it looks like you have the neg and positive wires diagonal from each other separated by the entire length of the plywood. Any help greatly appreciated. I'm watching these and taking notes for my first DIY panels.

[gcdrummer02]

@1978CamaroRedneck

the front of the cells are positive and the backs are negative. All the cells are wired in series to help build up voltage. If they were wired in series, they would build up amperage.

[EXTREMEGNASHER]

I commend you for your effort! Nice video! I would like to see you do another one now that you have worked out some of the bug! What do you say?

[mrairjer]

soldering the wire directly to the buss wire would have been a lot better.

More isn't always better. You only need enough solder to make the two connection bond. The solder should lay flat and smooth and still be shiny when done properly. Clumpy solder is a result of one or more of these (too much solder, not enough heat, too large diameter of soldier. The end of your iron should be "tinned" and look shiny when you are soldering joints.

Otherwise nice job!

hi robert,your video on u tube very informative,but is too slow,any chance me getting the complete video?how much ect,kind regards keith

[CTOL1]

Robert, First Good Project High Fives very informative

The weakest link I see is the crimp on eyelet terminal Personally I don't like them, too many things can go wrong, over crimped causing the wire to break prematurely, to loose, corrosion etc.

For the tabbing and buss wire. Try folding the extra over the other, same for your power leads. You will have twice the surface area for better contact and mechanical / electrical bond. Crease it only once can cause metal fatigue in the flat wire!

Mr Robert, Your project is a great idea to share to all of us learning now how to built a solar cell. Can you find a website that sell aluminum frame with the glass , this be a plus. a frame that will fit to 36 cells ( 3x6) and get the proper size to us. Also Can you guide me on how to Built a 175 watts solar cells frame. how many cells do I need. Whis is a better selection. 3x6 or other size cell, wher can I buy cells website. thanks again for all your support Franco

[Anothercoilgun]

Tile spacers.  Is there anything they are not good for :)

[englewood1961]

Did you check the current and voltage with a load in sun light? Those evergreen cells don't put out 1.7 watts each, the 3.5 Amps is a short circuit current, not to be use to calculate power. You need the Vmp and the Imp to calculate the max power.

[RobertSmith3]

Very true, however, we have to keep in mind that for the typical Do It Yourself (DIY) person, they usually do not have the equipment necessary to test these the actual Imp/Vmp/Pm. For most DIY solar panels, we by default test the open circuit/short circuit rather we say it or not. So my goal here in these videos is to keep things simple and follow the approach of a regular DIY solar panel, and not a fully professional built and tested solar panel. Of course if you can afford a MPPT go for it.

[Stime64]

You are doing a great job!

[RobertSmith3]

Thanks! :)

great video. thanks for the help
