Solar Aligner
Optimal direction & tilt for UK solar panels
What it does
Solar Aligner calculates the best compass direction and tilt angle for a fixed solar panel at your exact location. Enter a postcode or use GPS, then lay your phone flat on the panel — a live tilt gauge and compass needle guide you onto the target, with haptic confirmation when you're there.
Features
- Optimal orientation for your latitude, with Annual, Summer and Winter presets
- Live phone-on-panel alignment — tilt from the motion sensor, direction from the compass
- Sun times — sunrise, solar noon and sunset for your location, every day
- Sun path chart — how high the sun climbs through the day
- Noon sun height at midsummer, the equinox and midwinter — see what winter shading costs
- Private by design — no account, no ads, no tracking; the only network request is the optional postcode lookup
Sun position uses standard published astronomy, verified against the US Naval Observatory to a fraction of a degree. Solar Aligner is an independent app and is not affiliated with or endorsed by any certification scheme or installer body.
