SolarLock

Solar Panel Alignment Instrument

This tool uses your device's compass and tilt sensors to help you align solar panels for maximum energy output.

Your location is needed to calculate the sun's position. All processing happens on your device — no data is ever sent anywhere.

Sensors Denied

Compass and motion sensors are required for alignment. Please enable them in your device settings, then reload this page.

No Compass Detected

This device may not have a magnetometer. Some devices provide orientation without a compass — try rotating slowly in a figure-8 to calibrate.

Information

SolarLock helps you align solar panels to maximize energy capture. Hold your phone flat against the panel surface and tilt it toward the sun.

All calculations are performed locally on your device. No data is transmitted anywhere.

For best results, calibrate the compass before use and avoid standing near large metal objects.
