Common questions
Do I need a solar time calculator or a panel tilt calculator?
A solar time calculator concerns the sun's position and timing, while this tool gives a fixed panel-tilt starting point from latitude. The NOAA solar calculator provides sunrise, sunset, solar noon and position calculations. NOAA currently says that service is no longer actively maintained, so review its limitations before relying on it.
計算方法
結果を使用する前に
A heuristic, not a weather-based optimization. Roof geometry, shading, wind, soiling and time-of-use demand can favor another tilt or orientation. West-facing systems may shift output later in the day without maximizing annual energy.
Is true south the same as compass south?
Not always. Magnetic declination varies by location. Use true north/south for the azimuth reference.
