Calibrated Solar Forecasting
SunPlanner calibrates its 16-day production forecast to what your system actually makes, so the numbers reflect your rig, not a generic estimate. The compass is calibrated too, so sun-finding stays accurate even next to metal and battery banks.
First 20 testers get a free year, the next 30 get 50% off.
Other solar apps estimate from your panel specs and stop there. SunPlanner keeps going: it tunes the forecast to what your system actually produces, so the numbers match your rig. No other app calibrates to your real output. On the compass side, metal and battery banks shift the magnetometer reading by 10 to 30 degrees. SunPlanner calibrates that too, so sun-finding stays accurate in the places you actually use it.
Give it your panel specs and a location, and you get a day-by-day production forecast. Your current spot, your cabin, your mooring, or anywhere you're considering. Not a regional average.
Save spots or tap the map. Useful before you decide where to set up, or just to see what tomorrow looks like from where you are now.
Point your phone and see where the sun rises, how high it gets, and when it sets. Helpful when trees, a hill, or a building is cutting your production day short.
SunPlanner is entering closed beta on Android first, with an iPhone build on the way. We want testers with real systems: panels, an inverter, actual production numbers to calibrate against. Pick your platform above and join the list. The first 20 testers get the full app free for a year, and the next 30 get 50% off. No credit card, no auto-billing.
