Hello everyone,
I am a newbie to solar power and this forum. I have purchased some 6"x6" and 1.5"x4" solar cells and am in the process of planning to build two panels. One will be 18v (36 each 6"x 6" cells) and the other will be assembled as a small 16v "camper battery" charging panel. (If I would have had another four cells I would have made it an 18v panel too) I have attached a .jpg schematic of the smaller panel to this post.
I have two questions...
1) Is the wiring diagram in the attached schematic correct? I did this in Visio on my own so that I would have a clear plan to follow during assembly. This is my first attempt at tying tabbing wires and bus wires together. I will be terminating everything in an Evergreen Solar junction box.
2) Four of the cells are rated at 8A, while the other 28 cells are rated at 1.5A. All have equal voltage rating obviously and will be wired in series to achieve 16v. Is there an easy calculation that would tell me how many amps to expect from a mixed cell size configuration? I'm estimating about 2.2A for the panel, but not sure.
Any comments or pointers would be appreciated!
