Forecast

Check My Solar can show solar generation forecasts for the next few days. Forecasts help you plan usage and see expected production. The app supports two providers: Forecast.Solar (free) and Solcast (premium, API key).

Where you see forecasts

Section titled “Where you see forecasts”
  • Forecast view — In the dashboard, the forecast section (or forecast tab) shows predicted generation for today, tomorrow, and the next several days. You can switch between days (e.g. Today, Tomorrow, +2, +3 …).
  • Tomorrow’s forecast notification — If the solar forecast integration is enabled and you turn on “Tomorrow’s Solar Forecast” in Notifications, you can get a daily push with tomorrow’s expected generation and peak times.

Setting up a forecast

Section titled “Setting up a forecast”

Forecasts are configured per device (inverter). Open Menu → Account (or Notifications) and use the option that opens Forecast / Solar Forecast setup (sometimes under “Advanced” or “Notifications” depending on the screen).

Forecast.Solar (free)

Section titled “Forecast.Solar (free)”
  1. In the forecast setup, choose Forecast.Solar (or “Free” provider).
  2. Add at least one roof (installation):
    • Label — e.g. “Home”
    • Latitude / Longitude — Your installation location (e.g. from MapQuest or similar).
    • Capacity — Installed kWp (e.g. 5).
    • Angle — Tilt in degrees (e.g. 30).
    • Aspect — Azimuth/orientation (e.g. 180 for south).
  3. Save. The app will fetch forecasts (e.g. 48-hour or extended) and refresh periodically.

No API key is required. Data is updated automatically (e.g. every few hours).

Solcast (premium)

Section titled “Solcast (premium)”
  1. Get a Solcast account and API key from Solcast / account API key.
  2. In the forecast setup, choose Solcast and enter your API key and (if required) Resource ID for the site.
  3. Save. The app uses Solcast for higher-accuracy forecasts where configured.

Solcast may have usage limits depending on your plan. The app uses a single forecast endpoint; if both providers are configured, the backend may prefer one (e.g. Solcast when available).

What’s shown

Section titled “What’s shown”
  • Per day — Expected generation (e.g. kWh) for today, tomorrow, and the next days.
  • Peak times — When the sun is expected to be strongest (where the provider supplies this).
  • Charts — Forecast curves or bars for the selected day.

Forecast data is predictions; actual generation depends on weather and system performance.

Tomorrow’s forecast notification

Section titled “Tomorrow’s forecast notification”
  • Only available when a forecast integration (Forecast.Solar or Solcast) is set up for the device.
  • Enable it in Menu → Notifications: turn on Tomorrow’s Solar Forecast and set your preferred time (e.g. 6 PM).
  • You’ll get a push each day with tomorrow’s expected generation and peak times.
