Maybe this question is already been answered, but I am asking it too.
I am new to NGSPICE, I always worked with PSICE, working with the schematics. NGSPICE is working with the .cir files, right?
Is it possible to draw schematics? or maybe use another program to draw schematics?
or what do you prefer?
ngspice does not offer schematic entry. Third party tools use ngspice as simulation engine.
You may find a first info here:
In addition xcircuit (http://opencircuitdesign.com/xcircuit/) allows schematic entry and generation of a spice cir file.
Thanks for the info.
I am first trying to make a .cir file only using NGSPICE. I want to simulate a solar cell. but I need to make a whole solar module in ngspice. so i think i need to work with parameters for the different PV cells. I send a picture of what i waant(schematic) and what i got, (ngspice .cir file)
can you please have a look and give me some advice.

I use Kicad as a front end all the time... Just watch your node numbers on devices like BJTs and FETs.
It makes very nice schematics. You can use a symbol for a part like a BJT and have the pins match the real part, but tell the tool to override the pin numbering so it matches what Spice wants to see, i.e. collector is pin 1.
