Built a tiny free site that tells you the best hours to run appliances tomorrow, does it match your real production?

Built this over a few evenings and I'm at the point where I need real systems to tell me if it's accurate or garbage.

The idea is to enter your panel specs (kWp, tilt, direction) + location, and it spits out today's and tomorrow's production curve and the best window to shift heavy loads into. Aimed at folks without home automation or a battery, give me some feedback please, thank you :)
