For full-time mobile off-grid living
Plan the power before the road decides for you.
SunPlanner estimates how much solar your setup may produce today and across 16 days. It is built for people who depend on off-grid solar, whether that system powers a home, cabin, van, bus, or converted rig. This guide focuses on mobile setups that move between camps, live without hookups, and need to plan real loads around the sun.
16forecast days for the rig and location you select
Life beyond the hookup
A moving home needs more than a generic weather forecast.
01You may need to choose the next camp before you can see its trees, terrain, or solar window.
02A cloudy stretch changes when the battery bank can comfortably carry flexible loads.
03Moving changes the location and weather inputs. Logged production teaches SunPlanner how the same rig behaves.
Start with this rig
Keep today's solar outlook close to the loads you need to run.
Configure the array and location you are using. The Dashboard brings today's energy estimate, expected range, confidence, and PowerBar together so you can judge the day before turning on a flexible load.
See how the forecast works
Before the next stop
Check the useful sun before you commit to the campsite.
Search the place you are considering, choose the exact result, and compare the sun path with your panel direction for the date you plan to be there. You still judge the trees, terrain, and other obstructions you can see.
Before the heavy loads
See the stronger days and plan around the weaker ones.
Compare daily solar estimates across 16 days. Each day has its own range and confidence, so you can move charging, cooking, cooling, or travel toward the part of the outlook that gives the rig more room.

Let logged production teach the forecast about this rig.
Log the final kWh your system produced. After three usable readings, SunPlanner starts applying what it has learned to future forecasts. The calibration profile keeps building toward 25 usable readings.
Straight product truth
Know what the app is telling you.
A planning estimate
Daily energy, the expected range, confidence, and the PowerBar are forecasts. They are not live readings from the inverter, battery, charge controller, or utility meter.
Sun geometry you can judge on site
Sun Finder shows the sun path and panel direction. It does not calculate tree height, terrain shadows, or obstruction shading for you.
A new place changes the forecast inputs
Changing the selected location updates the weather and solar conditions. Calibration changes from usable production readings, not from movement alone.
Built for off-grid decisions
Make the next off-grid power decision before you turn the key.
Configure the rig you actually use, check the days ahead, and compare the sun at the place you are considering.
