Instant browser-based solar prototype simulator that runs smoothly on any laptop or phone
Students developing solar power prototypes can't reliably simulate designs because current software crashes on basic laptops and lacks mobile support.
SolarSimly provides a lightweight, cloud-powered simulation engine that handles complex solar designs without crashing basic hardware. Students input panel specs, wiring, and environmental data via an intuitive drag-and-drop interface, getting real-time results instantly. Fully mobile-responsive with offline caching for fieldwork simulations.
