How to use the Solar Generation Scenario Calculator
Peak-sun hours represent irradiation equivalent to rated full-sun power, not the time between sunrise and sunset. Enter a location-appropriate scenario and a separate loss factor.
The calculation
Worked example
Ten 400 W panels, four peak-sun hours and 80% retained output give 12.8 kWh/day, or 384 kWh over 30 identical days.
Assumptions and limits
No weather or location data is fetched. Shading, orientation, inverter limits, temperature and seasonal variation are not individually simulated. This is a constant scenario rather than a production guarantee.
Common questions
Are daylight hours the same as peak-sun hours?
No. The sun’s irradiance varies during daylight; peak-sun hours are an energy-equivalent measure.
Does this size an inverter or electrical system?
No. It estimates energy only from the assumptions supplied.
