Solar Yield Estimator
Estimate how much energy your solar system will produce each month based on location, orientation, and system size.
Check string compatibility
Verify if your panel-inverter configuration is safe and within limits.
Find compatible panels
Search all compatible solar panels for your inverter.
Already have panels?
Find an inverter that fits your panel array with the right MPPT range and DC/AC ratio.
How the solar yield estimate works
This tool estimates monthly and annual energy production for a grid-connected PV system at any location. It uses real historical irradiance data from the PVGIS-ERA5 database maintained by the European Commission's Joint Research Centre.
The estimate accounts for your panel orientation (tilt and azimuth), system size, and typical losses from wiring, inverter efficiency, soiling, and temperature effects.
How to use the estimator
- Set your location by clicking the map or dragging the marker
- Enter total system peak power in kWp (kilowatts-peak at STC)
- Adjust the azimuth — the compass direction your panels face (180° = South)
- Adjust the tilt angle — how steeply your panels are angled from horizontal
What affects solar production?
Solar yield depends on geographic location (latitude, climate), panel orientation, shading, temperature, equipment efficiency, and system losses. This estimator provides a good starting point — actual production may vary due to local weather, shading, and equipment-specific factors.
