See what the sky is doing before it hits your roof.
Surpl SkyCast blends Meteosat satellite imagery, cloud motion and your home context to estimate solar generation for today and tomorrow — plus sub-hour nowcasts when clouds are moving fast.
- Ten-minute satellite refresh over Ireland
- Day-ahead and sub-hour nowcast signals
- Confidence labels so you know when to trust the view
- Built into Surpl Flex, Alexa and Energy Signals
Irish weather changes quickly. SkyCast helps you plan charging, hot water and appliance timing with a clearer picture of what the next few hours will look like — without reading raw weather charts.
What SkyCast does for households
- Estimates expected solar output for today and tomorrow from your panel setup and local conditions
- Tracks cloud motion with sub-hour nowcasts when change is imminent
- Surfaces simple guidance on when to run flexible loads or charge your EV
- Works alongside official grid data where indicated — always labelled clearly
How it works
SkyCast ingests Meteosat infrared imagery, applies cloud-motion modelling, and fuses signals at your grid cell. For members with connected inverters, live telemetry can refine the picture over time.
Pro members unlock the richest SkyCast experience on Energy Signals — advanced weather views, nowcast context and prediction insights wired into orchestration.
Alexa and daily guidance
Link your Amazon account and enable the Surpl Home skill to hear solar and charging guidance from your speaker. Surpl answers from your live data and SkyCast — it does not guess when confidence is low.
Official data and Surpl analysis
Where Surpl shows official grid information, it is clearly labelled. SkyCast forecasts and nowcasts are Surpl analysis — useful for planning, not a substitute for official system operator signals.

FAQ
Do I need solar panels?
SkyCast is most valuable with solar, but cloud and renewable-window context can still help EV and heat-pump households plan flexible loads.
Is the nowcast official?
No. SkyCast nowcasts are Surpl analysis based on satellite and weather inputs.
