Know where you stand.
Battery charge, solar input, and power use sit together. See whether you’re saving sunshine or using what you’ve stored.
Horizon Science · Introducing Horizon Solar
Solar, made simple.
A little clarity for your everyday energy. See what’s coming in, what’s being used, and what’s saved for later.
Interactive demo · Works in your browser · No account needed
Less to figure out. More to enjoy.
Your energy should
feel easy to understand.
The redesigned app starts with a simple question: how’s my system doing? A clear battery view, useful numbers, and everyday language help you find the answer at a glance.
Make it a routine.
Give your plugs a daily schedule or timer. Set a battery reserve, and the demo pauses a plug when power runs low.
Follow the light.
Choose automatic tracking, a resting position, or your own angle. A dedicated Panel screen keeps the choices clear.
Five simple places. One familiar feeling.
Find your way around.
Explore each screen in the working demo. Your changes stay in this browser.
A clearer view of your day.
Start with your battery, today’s solar energy, and the plugs using power right now.

A little room to explore.
Try the new interface right here. All readings and controls are simulated.
Demo readings are simulated. Earlier energy history is illustrative; today’s total accumulates while the app is open. Real controller integration is still in development.
Designed together
A natural companion
for Sunflower.
The app shares the updated Sunflower’s quieter design: soft surfaces, careful details, and room to breathe. The original twelve-petal shape stays at the heart of it.

Try it today.
Watch it grow.
The app runs in your browser with a simulated controller. Try sunny, cloudy, and night conditions to see how energy and battery behaviour change. Device capacity, plug schedules, and tracking choices also affect the demo.
The hardware is being developed separately with Charlie. The next step is bringing actual controller readings into this interface.
Designed for everyday use
Five clear views, large controls, a phone-friendly bottom navigation bar, keyboard access, and dialogs that work with assistive technology.
Make it feel like yours
Choose light, dark, or automatic appearance. Start with warm bronze, or try sage and sky accents, name your system, and set its example battery capacity.
A closer look at your energy
Explore day, week, month, and year charts. Select a bar for details or export the selected period as a CSV. Everyday energy equivalents include their assumptions.
Built with React
The interface uses React and Vite, with reusable components and separate simulation logic. Preferences, demo devices, and plug routines are saved locally. No real hardware commands are sent.
