Hey All,
I'm in the process of designing an off grid system and I've been reading and posting to this forum and it's been awesome. Great community here! I find the sticky posts on this forum to be particularly good and try to read them all at least twice. That being said I'm still wading through the mountains of choices.

If you've ever played with microprocessors like Arduino or Raspberry Pi you might be familiar with Fritzing which is a circuit designing software. Basically you input your various components and the software helps you design a safe and functional circuit diagram.

I know there are lots of design tools for off grid solar PV systems out there but haven't found one that doesn't ask for my name and address.

Looking for recomendations for design websites or software.
