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 cloud, haze, snow, soiling or high cell temperature. The system_derate factor covers cabling, controller and temperature losses as one flat number and defaults to 0.8. Shading is not modelled here. Times are UTC. Use the figure as an upper bound for sizing, not as an expected daily production.

More from Halowerk & similar services
Halowerk · LLM Catalog
modell.halowerk.com
A comparison table of language models: input, output and cache prices per million tokens, context window, maximum output length, batch discount and a short note on what each is suited to. Filter by vendor, by a maximum price, by the context window you need, or by capability tag. Every row carries the date its prices were last checked, so a stale figure is visible rather than silently wrong.
Halowerk · EV Charging
karte.halowerk.com
Queries OpenStreetMap for charging stations within a radius of a point and returns each with its position, distance, operator, network, connector types with their individual power ratings and socket counts, access restrictions, fee status, opening hours and whether authentication is required. Results are sorted nearest first and can be filtered to a minimum power or a required connector type, which is the question a vehicle actually has.
Halowerk · Inverter Load Check
solar.halowerk.com
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 continuous load, which is the case that trips an inverter; simultaneous starts of two motors are reported separately as a second figure. Starting factors and power factors are design rules of thumb per appliance class and are stated in the response, they are not device data.
