I wrote a solar power system designer for small-scale solar projects. It started as a PC Parts Picker for solar panels, but I added a simulator and a few other features focused on solar power.

Would love to know what you think about it!

Some takeaways I had playing with it quickly:

I think "Time of Day" numeric value display in the simulator is using "Day of Year" as the refresh requirement (remains static through changing time, but with update if manual change time or date).

The physical space display at the top of the simulator is cool, but difficult to see everything on mobile.

I like the power line diagram in the builder. Makes it very easy to understand how things would hook together.

Thank you! I will look at the Time of day bug. I will think about the mobile simulator.
