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 NOAA currently says that service is no longer actively maintained, so review its limitations before relying on it.

Berekeningsmetode

Rule of thumb: annual tilt ≈ absolute latitude. Winter tilt ≈ latitude + 15°; summer tilt ≈ latitude − 15°, limited to 0–90°. Tilt is measured from horizontal; azimuth is measured clockwise from true north.

Voor jy die resultaat gebruik

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.
