I like the idea of solar and have got a few old Christmas battery/panel modules to play with. I am struggling to hide them in the layout.
I use a bit of proprietary SW for that purpose. [similarly to the way you program a loco]
That sounds like a pretty nice setup NCS. What software are you using to program your decoders?
How long do the 18v incandescent bulbs last for?
I am using a number of Massoth switch decoders also, although most are fully occupied. The max. for each output in the manual is 1.5 amps.
I run a 12V bus and then use these little DC-DC powersupplies to control the brightness of individual LEDS though I have groupings of leds run off each one. I also have discovered warm white leds with a diffused lens gives a really good incandescent light colour.

Coloured LED's are made so that the 'emitting' part is excited at a certain frequency.. Different frequencies emit light of different colours.I don't know if the LED bulbs are intrinsically coloured, or whether they just paint the glass around a white LED to get the required colour. I am hoping it will be the former!
