My plan is to build a small solar farm as part of a train display, using ten to

My choices are:

Wow, cool project, please post more when you can!

(...) Well... first, if you connect 10 ten to twenty potentially 2V panels up in series, you're potentially cranking up to 20 to 40 VDC, but at other times you're going to have almost nothing for power. And if you connect all these in series, you're (...) (15 years ago, 4-Sep-09, to lugnet.technic)
