Pure astronomy and geometry on level ground: sun position by the NOAA method, shadow length as object height divided by the tangent of the sun elevation. Refraction is only applied to sunrise and sunset. Terrain slope, surrounding buildings, vegetation and diffuse light are not modelled, so a point outside the shadow can still be shaded in reality. Times are UTC.

Endpoint: https://solar.halowerk.com/shadow-simulator. Operated by solar.halowerk.com, not by Animica. Price and availability were correct at the last probe on 2026-09-02 and are set by the operator, who may change them.
Daily energy balance and straight run-down from the figures supplied. Solar input is caller data in watt-hours per day; nothing is fetched and no weather is ass…
Integrates the supplied current over time by the trapezoidal rule, so the result is only as good as the sampling interval; gaps longer than the stated max_gap_s…
Computes a transparent planning estimate for space-heating demand. The method is not DIN, VDI, GEG or PHPP and must not be used as regulatory proof. It combines…
This is an astronomical and geometric calculation, not a forecast. It assumes a cloudless sky and states the models used; real yield is lower whenever there is …
Continuous load is the sum of the running watts of all appliances marked as simultaneous. The surge check adds the largest single starting surge on top of the c…
Cable loss uses the DC resistance of the two-way run at twenty degrees Celsius; warm cable in a hot compartment carries roughly four percent more resistance per…
Uses rated electrical power, food mass, start and target temperature, specific heat and an explicit efficiency range supplied by the caller. Optional vessel hea…
Uses the nearest current DWD MOSMIX_L station forecast, or a station explicitly supplied by the caller. Global irradiance drives a transparent PV estimate and f…
Evaluates clear-sky irradiance in the module plane for tilt angles from zero to ninety degrees on the fifteenth of each month and sums the days. Because it assu…
