HelioCast — kWh forecast per solar-system body
PSP measures the Sun directly; JWST observes other bodies that reflect sunlight. For each body, geometric solar flux × multi-junction PV efficiency gives the kWh per m² per day available at that location. Click a body in the 3D scene for its 24 h forecast.

HSO multi-probe coincidences
When PSP fires a PVI event, we Parker-advect it to every other probe and check for a real event within ±20° / ±24 h. Matches below.

kWh formula & caveats
Per-hour kWh / m²: TSI / r² × η × Δt where TSI = 1361 W/m² (solar constant at 1 AU), r = body-to-Sun distance in AU at the forecast hour (from JPL Horizons), η = 0.30 (multi-junction PV efficiency, Spectrolab XTJ Prime), Δt = 1 hour.
Daily (24 h) kWh / m² is the sum of hourly values; integrates orbital motion over the horizon.
This is an upper bound assuming an ideal Sun-tracking collector, no atmosphere, no eclipses, no rotation losses. Real harvester yield is a fraction of this. PSP-event flags (orange dots) mark hours where a wind-mechanism PSP disturbance is predicted to arrive — those hours likely deviate from geometric prediction.
