**Looked into Line Loss re: barn and solar panels. I learned that most people call it wire loss and it I got confused with the voltages listed on the catalogue. The modules have voltages such as 16.3 that are significantly above the system voltage (which I assumed was twelve as the introduction to the products said it was) I was informed later by Charlie that voltages are extremely flexible, that the voltages listed were the peak (possibly unattainable) performance and that parallel and serial wiring will be covered in greater depth later. This put my mind at ease. From what I know now I'd venture a guess that we'll need about 360-400 feet of 4 gauge wire for a 48DCV system transmitting about 10 watts or 480 watts though we'll probably be running most of the time at lower than that. What I do know for sure is that we have about 45'x13' of space to work with on the barn roof. That's enough for 26 of the largest models of modules.

I learned that most people call it wire loss and it has nifty tables that illustrate the relationship between wire thickness, length, and amperage transferred.

**worked on the Watt Node with the rest of the class. Had difficulty figuring out how to hook up the display to the watt node as they were made by different manufacturers. However, after consultation with the manuals and a translation of technical language from Charlie figured out where the ground and the power went. Came to several realizations about how complex systems are set up without a kit or intended relations between products of the same manufacturer. Other items: Learned how to tin the ends of wire with solder to make them manageable. Set up learning how to weld and braze from Charlie. Have yet to arrange something more finite.
