HelioScale: Solar Irradiance

HelioScale is an offline-first solar science explorer that lets you calculate and compare solar irradiance, planetary distances, and theoretical solar-panel energy output across all eight planets of our solar system. Whether you're a student, hobbyist, or just curious about how sunlight intensity changes as you move away from the Sun, HelioScale turns real physics into simple, interactive tools — no internet connection required. FEATURES ☀️ Solar Irradiance Look up the distance and calculated solar irradiance for each of the eight major planets, from scorching Mercury to distant Neptune. ⚖️ Compare Pick any two planets and instantly compare their distance from the Sun and the solar irradiance they receive. 📏 Distance Explorer Drag a slider to see irradiance change in real time using the inverse-square law — a hands-on way to understand why closer planets receive so much more solar energy. 🔋 Panel Simulator Enter a solar panel's area and efficiency to estimate its theoretical electrical output at any world in the solar system. 📚 Learn Short, original explanations of the physics behind solar irradiance, the inverse-square law, and solar energy — written to be easy to understand.
