Surpl SkyCast

Everything we built for weather, in one place. See what’s coming over your area, act on it faster, and plan solar use with more confidence — from the next hour through tomorrow.

This page is the full story of Surpl SkyCast: what it does for you, how it works behind the scenes, and why Pro unlocks the richest forecasting experience. It is a product explainer first and an upgrade path second.

Live sky monitoring

Know when conditions over Ireland are shifting before they show up on your roof. Surpl SkyCast ingests Meteosat satellite infrared imagery every ten minutes so you are not guessing from a static weather icon.

  • EUMETSAT Data Store (Meteosat HR SEVIRI) as the live sky source
  • Ireland-focused crop — area-level, never household-precise
  • Always labelled as a Surpl estimate, not an official national forecast

Cloud movement nowcasts

See roughly when cloud cover may reach your grid cell and how PV output could be affected in the next few hours — so you can time appliances, charging, and hot water with fewer surprises.

  • Minutes-to-cloud and PV impact estimates on Energy Signals
  • Confidence badges: High, Moderate, or Low
  • Complements day-ahead Surpl SkyCast — it does not replace official weather forecasts

Forecast fusion across data sources

Get a clearer surplus picture when day-ahead weather, live satellite motion, and your inverter readings point in the same direction — or when they disagree and you need more context.

  • Day-ahead solar baseline via Surpl SkyCast
  • Sub-hour Surpl SkyCast signal when cloud is imminent
  • Orchestration alerts first; device automations only with explicit control consent

Privacy-safe crowd confirmation

Strengthen confidence when several nearby opted-in homes detect a similar PV drop — without exposing who contributed or sharing exact addresses.

  • Opt-in only, with a clear “See what is shared” detail screen
  • Aggregated grid cells and 10-minute buckets — k-anonymous thresholds before any boost
  • Revoke anytime from Energy Signals

Pro-only insights and advanced views

Unlock the complete Surpl SkyCast experience on Energy Signals: advanced weather views, richer nowcast context, and prediction insights wired into orchestration — for members who want more than a simple weather check.

  • Surpl SkyCast card and nowcast API on Pro (prediction insights)
  • Fusion-weighted surplus confidence in household orchestration
