How To Build A Solar Panel - Part 6

[jrchairez]

Why dont you use the silocone to hold it down while you soder?

[NewnotesJR]

Okay, I see, so one column goes from back to front all the way down, the next column goes from front to back all the way down, and you're third column is going from back to front again all the way down right?

[NewnotesJR]

Having some solder on the tip of the iron helps to conduct the heat into what you're trying to melt solder onto.

If you have a wet sponge, you can easily melt a bit of solder onto the iron tip and then wipe the excess solder onto the wet sponge so that the tip remains with the silver color of the solder.

Hey Robert, if you have all these videos on a disc that I can watch without the youtube buffering that jacks up the video, I will pay to have you overnight it to me. thanx! jimmy browder

[dimpychhabra20]

which solar cell should we use the one you have used in the video or the square ones?? which is better and what is the voltage produced by a group of 4X9 panel or 3X12??

[SunGreenSolarEnergy]

Do solar flares and sunspots have any adverse effect on solar energy systems?

[kevlaxer]

Do you need 36 or can it work with just 24?

[1981dasimpson]

also apply the soldering iron to both peaces of metal to be solderd then apply the solder

[1981dasimpson]

double sided tape is best way to hole the bus wire in place

[frankt04]

@kevow7 the voltage is constant

[LiluyeLanna]

What House hold items can one of these power?

[LiluyeLanna]

What can the panel power?

[permacultureli]

thank you Robert...i have a permacultural project just south of the border...in Baja...lotsof sun...and will proceed to make my panels thanks to your clear and complete inclusion of the whole process here...you are doing this at the very best time...when we need it. keep up the great work!.

[qcages]

dude you're my hero. These videos are great. I think i'll be ordering my first cell kit soon! These videos helped me realized it's not an impossible project, and with these types of cells, a panel like this isn't insanely expensive :)!

[kevow7]

is it 10 volts per second or minute?

[rgaff357]

Mr Smith, I think you could have named your video How to make solar panels for Dummies. Excellent Job young man

[zameul35]

Your connecting your - and + together on all cells so your multipling voltage but your amperage for the whole panel would be the same as only one cell right? If i remember right all your + and - hooked together multiply voltage if all your - to - and + to + you would be multipling amperage not voltage? I know enough about electricity go get me into trouble.

[MegaSolidSteel]

do you have to use bus wire or can you use tabbing wire instead of the bus wire  i dont want to have to spend money on bus wire when i can use tabbing wire

[RobertSmith3]

@MegaSolidSteel Yeah you can use tabbing wire. Most use bus wire because of it's width allowing you easily connect strings to one another and for use in junction boxes. But it's up to you how to go about it :)

[SirSchumii]

Serius maybe im just tirred.

But when u series 24* 5 voltage how can you end up with as litle as 10 V ? sound more like paralel connection 12* paralel to raise Ah and then 2*12 serial to double the voltage ?

A car battery is 12 V = 6 cells * 2v in a series. like in a remote control were plus meats minus to raise the voltage . But ur mesured 1 cell to 4.13 V (5 in the sun)

Tell me whats gone wrong in my head plz c",)

[pauluminous]

@SirSchumii

each cell is 0.5 (zero-point-five) volts :P

[bearboneskentuck]

put a drop a solder on the iron first

[zliminator]

If there is just one cell bad, then you won't get any reading, correct? I know, you were supposed to check each one when glueing together like you showed in the previous video.

[RobertSmith3]

@zliminator Yep, if one goes bad, it messed up all the strings of solar cells.

[RobertSmith3]

@zliminator Or I should say, electricity cannot successfully travel from one end to the other with a dead cell in the string, but it doesn't destroy your other cells, you just will not produce any power :)

[creasyj21]

Were these cells shipped with a wax coating? They look like the may have wax on them... I could be wrong but this close-up view in the light looks strange.

[zliminator]

@creasyj21 I saw someone on the web said that sometimes they ship with wax to help prevent damage. You can put them in hot water to melt the wax.

[daniel46148]

Try using some flux to clean the materials so the solder bonds better.

Great video!

[tedohho]

Thanks again Robert , this old man is learning alot. Your great in teaching.. God Bless and keep it up

[birdwing98]

Be very care with all those scraps of tabbing wire that you trim. One of those tiny scraps might be lost in the panel, and move around latter causing a short. I am beginning to understand what you are saying about the three sections being in series. From left to right, the current flows UP, DOWN, and UP again. OUCH! I just saw a pile of those tab scraps sitting on your pegboard. Find a better trash area!!!

[birdwing98]

Those tab wires like to jump around! Use small rocks, wooden blocks, or other weights to keep those rascals still. Keep up the good work.

[Sp33dstix]

Nice vids, my group and I are trying to create a Peak Power Tracker (make a solar panel operate at maximum power at a given voltage) we ordered the cells and were looking for a way to mount the cells. Great vids, thanks for shedding some light on this subject.

[centralscrutinizer76]

i always wanted to try to build a solar panel but was afraid the cells would break .think i may try it after watching your video .

[1978CamaroRedneck]

Great videos!!!!!! Thanx for sharing your wealth of knowledge!!!!!!!!!! I'm just finishing video 5. In the vids to come are you going to talk about tapping these into the main power grid so you don't have to use battery storage? awesome videos thanx

[o1OpTiMuS1o]

good stuff man awesome vids. you got good patience too

[rayofminneapolis]

"Pixel Glass is awesome!"

[joe18370]

what abought the ground wire,what does it hook up to

[RobertSmith3]

In this video I'm not hooking up any gauge wires, but only have a temporary wire in that hole to prevent the hole from closing by the silicon.

[edstar83]

Awesome!

[EdwinRamos89]

GREAT VIDEO
