OnSun: Solar Forecast & Plan

Schedule Appliances, Cut Bills

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Solar panels don't save you money. Using your solar power at the right time does. OnSun forecasts your production and schedules your appliances at the best times. Power bills are rising. Solar panels help, but only if you use them at the right time. Most solar households export more than half of what they generate at 4–6 cents per kWh, then buy it back at 25–35 cents when they actually need it. The panels are working. The timing isn't. OnSun fixes that. ------------------------- WHY TIMING MATTERS A typical 6.6kW solar system peaks between 10am and 2pm. But most household demand, washing, drying, dishwashing, EV charging, happens in the morning rush or evening. That mismatch costs the average solar household hundreds of dollars every year. Shift those flexible loads into the solar window and you use more of what you generate. That's less money to your energy provider, every single day. ------------------------- HOW IT WORKS 1/ See your solar before it happens Accurate 7-day solar forecasts based on the best available meteorological models for your specific location. Forecasts factor in your panel size, tilt and orientation — so the numbers reflect your roof, not a generic average. 2/ Schedule smarter Add your appliances in seconds. OnSun tells you the best time to run your washing machine, dryer, dishwasher, EV charger, pool pump or heating, with specific, actionable recommendations like "Run your washing machine at 11am Tuesday." 3/ Track your savings See how much grid energy you've avoided and what it's worth in dollars. Watch your self-consumption improve week over week. Long-term insights show how your habits are changing over time. ------------------------- SEE THE WEEK AT A GLANCE Gradient visualizations show solar strength across the entire week. Instantly see which days have the strongest production windows, no data science degree required. ------------------------- PRO FEATURES Upgrade to unlock: • 7-day solar forecasts • Unlimited appliances • Advanced long-term savings insights ------------------------- DESIGNED FOR REAL HOMES No hardware required.
