Read full description

With SenseraAlign, positioning your solar panel has never been easier. Simply place your device on the solar panel bracket and follow the onscreen instructions to best orient your solar panel. The Calibrate page helps with calibrating your compass sensors. The Direction page helps with pointing the solar panel in the optimal direction. The Angle page helps with tilting the solar panel at the correct angle for how many times the solar panel will be adjusted throughout the year. The different settings include: - 0-1 adjustments per year (Low efficiency) - 2 adjustments per year (adjusting every 6 months / Medium efficiency) - 4 adjustments per year (adjusting every 3 months / High efficiency) All calculations are based on location so enabling location permissions is highly necessary.
