How to build a solar panel part 10

In this video I am finishing up the frame and also talking about the blocking diode.

I started collecting old solar powered lawn lights that people threw away saving the solar cells, if you yard sale you can pick up a whole slue of them for a few bucks, I don't know how many have picked up on this.

@buckbeak1965 Great tip, Thanks

Thanks man for the showing I gotta build me a solar unit.

...and by the way thanks for sharing your ideas I'm having a great time learning and watching others experiments

I've enjoyed your videos and i like the fact that you've used recycled parts. I have a lot of fum with salvaged electronics myself. I noticed you have a miter saw, you could 45deg miter your corners on the outside of your frame and save having to fill the little hole also the corner brackets you used would have more to fasten to on the two inner most holes where as they way you have it now only two holes on one side and one on the other have a good bite. just an observation from a woodworker.

@buckbeak1965 I do not think so. After you put them together in series, Test your output and see how many volts you are getting. If you are charging a 12 volt battery you want right around 16 to 20 volts. After that you should be fine with just adding a blocking diode and then that is hooked up to a solar regulator. Then hooking it up to your deep cycle battery and then to your inverter. Thanks for the question.

@jonathans1212 I did not think about each cell having different out puts, will I have to build a regulating board for each cell?

@skippy3840 with home made pannels with different voltages its important because one can over power the other

i made one 2 sets of 38 cells with 2 6 amp diodes for each set

Usually, a good charge controller will take care of reverse power flow for you without having to use the blocking diodes on the panels.

@Den0Q hey Denoq, A blocking diode is like a resister. Its sole purpose is to block current from moving in the wrong direction...No such thing as a dumb question..Later from the west coast....
