Description
Portable solar panels aren't roof panels. The "just tilt it to 30°" advice is simply wrong when you're only charging for a few hours at a campsite. SolarPanelAngle finds the angle and direction that harvest the most energy for YOUR hours in the sun — then helps you physically aim the panel until it's right.
HOLD YOUR PHONE TO THE PANEL
Lay your iPhone flat against the panel and it reads the real tilt and heading
A two-axis target shows exactly how to adjust: "raise 8°, swing 12° right"
Sound and haptics guide you when you can't see the screen — because your hands are on the panel, not the phone
Turns green the moment it's aimed
OPTIMIZED FOR YOUR HOURS, NOT THE WHOLE YEAR
Tell it how long you'll charge — it finds the single best fixed angle for that window
Or track the sun right now for maximum instant output
A daily power curve shows what each angle earns, and compares flat vs best-fixed vs tracking
A NUDGE WHEN IT'S TIME TO RE-TILT
Portable setups drift as the sun moves — get reminded when to adjust
"14:00 — set tilt to 55°", scheduled to your own rhythm
A shade warning before a tree or ridge blocks your panel, and a pack-up heads-up before sunset
SEE THE SHADE COMING
Scan the horizon around your site and it predicts when the sun drops behind obstacles
"Effective sunlight 4.2 h (10:40–14:50)" — save each campsite and reuse it
FULLY OFFLINE — BUILT FOR THE BACKCOUNTRY
The sun is computed on your device from date and location. No internet, ever
Temperature loss is built in, so summer estimates match reality
One-time purchase. No subscription, no ads, no account. Nothing leaves your phone
SolarPanelAngle is a planning aid. Estimates assume clear sky; real output varies with clouds, temperature, shade and panel condition. Never stare at the sun or point the camera at it for long.
