I downloaded the videos with clip grab running on Ubuntu. They seem straight forward and not too technical.
Oztules, The videos show diodes but I will check for them anyway. Good point.
Ghurd, that looks like a plastic junction box available at major US DYI retailers. I wondered if that would work. J-boxes on flee-bay are about $10 per box. The non-acid silicon should not have the acetic acid (vinegar) smell. Correct me if I'm wrong.
Birdhouse, Thanks for the heads up about ordering information. I'll ask how long it will take to get them when I call.
Wolvenar, I'll be glad to do a post. It may take a while. BTW, there is talk among the politicians to put a big tariff on solar panels coming into the US now. I think most come from China anyway.
If my fuzzy math is correct, a 4KW system with all the trimmings can pay for itself in about 10 years. I'd pay today's solar prices simply to lock the cost of my future energy bills down and get dependable power. Of course, the system will not function without at least one wind turbine online.
Yes, there are worse addictions so I face it and keep building them.
Thanks for all the comments. Keep them coming.
