How to read and use the data

Dubrovnik solar forecast: daily weather versus long-term PV yield

The daily and annual figures answer different questions. Use the dated forecast to plan tomorrow, and the PVGIS specific yield to compare locations or estimate a typical year.

Dated, weather-based

Tomorrow's forecast

Tomorrow's value is a weather-based estimate for Tuesday, September 1, 2026: 49.8 kWh from the 10 kWp reference system, with a likely range of 41.5 kWh–54.6 kWh. It changes with the next weather forecast.

Multi-year climate baseline

PVGIS specific yield

Dubrovnik's PVGIS specific yield is about 1,441 kWh/kWp per year. It is a multi-year climate benchmark, not a prediction for tomorrow or for this calendar year. In the PVGIS profile, July is typically the strongest month and December the weakest.

From forecast to a household plan

Battery, EV, heat pump and flexible loads

Treat the forecast as a gross solar-energy budget before household base load and conversion losses. The numbers support scheduling; they do not guarantee surplus.

Battery

Keep room for the solar window

Use 11:00-15:00 as the first candidate charging window. Battery state of charge, reserve settings and inverter limits still decide how much can be stored.

Heat pump

Shift only flexible thermal demand

If comfort controls allow it, place discretionary hot-water heating or pre-heating inside 11:00-15:00. Never override frost protection, hygiene cycles or manufacturer limits.

Large loads

Avoid stacking appliances

A 3 kWp system scales to about 14.9 kWh for the day before household use. Run flexible loads sequentially during the strongest hours rather than assuming all forecast energy is simultaneous power.

Local questions

Solar forecast FAQ

How much could a 5 kWp solar system produce tomorrow in Dubrovnik?

Using the same south-facing, 35-degree and 14% loss assumptions, the 5 kWp estimate is 24.9 kWh for Tuesday, September 1, 2026, with a scaled likely range of 20.8 kWh–27.3 kWh. This is a linear reference-system estimate, not a site survey.

What does 1,441 kWh/kWp mean for Dubrovnik?

It means the PVGIS multi-year profile produces about 1,441 kWh in a typical year for each installed kWp under the reference assumptions. A 5 kWp system therefore scales to about 7,206 kWh in a typical year before site-specific adjustments.

Is the Dubrovnik forecast the same as the PVGIS annual estimate?

No. Tomorrow's forecast uses dated weather and an uncertainty band for one day. The PVGIS figure is a multi-year climate-based specific yield used for typical monthly and annual comparisons.

When should a battery, EV or heat pump use solar in Dubrovnik?

Start with 11:00-15:00, then check household base load, battery headroom, EV energy required and heat-pump safety or comfort constraints. The forecast estimates daily energy, not guaranteed instantaneous surplus.

Typical year

Solar production month by month in Dubrovnik

A standard 10 kWp system produces about 14,412 kWh in a typical year at this location. Monthly averages show seasonality; they are not a forecast for a specific year.

Values are kWh per month. Source: European Commission JRC PVGIS.

What makes Dubrovnik's solar profile different?The typical annual yield is about 1,441 kWh per installed kWp, ranking Dubrovnik #2 of 5 modelled locations in Croatia. That is 11% above the median of the 5 Croatia locations in this dataset. July is typically the strongest month and December the weakest; the stronger month produces about 2.2 times as much.

Method and data

Every city uses a 10 kWp system facing south at 35 degrees with 14% system losses. Tomorrow's figure combines hourly weather with GridPassport's PV production and uncertainty model. The monthly profile uses the European Commission JRC PVGIS multi-year climate series. Roof direction, shade, snow, dirt, inverter clipping and local weather can change real output.
