helisignaal

Helisignaal is a Dutch term formed from heli- (sun) and signaal (signal). There is no single, widely accepted definition, and the term is not part of standard Dutch technical vocabulary. In contexts where it is used, helisignaal generally denotes a signal related to solar position or solar radiation that feeds into a control or measurement system. The precise meaning depends on the domain and the documentation from which it originates.

In solar energy applications, helisignaal may refer to a control signal derived from sun-sensing instruments, irradiance measurements, or astronomical calculations. Such signals are often used in feedback loops to adjust solar trackers or mirrors in a heliostat field, with the signal potentially encoding sun angle, daylight status, or irradiance level. The signal can be analog or digital, and its exact content is system dependent.

Outside solar energy, rare uses may appear in photobiology or general signaling discussions, where helisignaal is employed as a label for sun-related signaling phenomena. These usages are uncommon and not standardized, so precise terminology should be checked in the relevant source.

Etymology and spelling: helio- comes from Helios, the sun; signaal means signal. Variants such as heli-signaal or heliosignaal appear in some texts, reflecting publication practices rather than a fixed norm. Given the non-standardized status, consult the specific document to determine the intended meaning of helisignaal in that context.
