Today, hour by hour, against a typical October day
Your solar year: a typical day in each month
Typical days are from the European Commission's PVGIS (PVGIS-SARAH3, 2005-2023 satellite radiation for this site), worked through your array's size, tilt and losses. About 4,956 kWh in a typical year.
Strong solar generation is expected between 07:00 and 17:00. Running your water pump or washing machine in this period uses sunshine directly instead of draining your battery.
13.1 kWh involved
About 11.3 kWh of solar energy will go unused between 09:00 and 17:00 because your battery will already be full. This is free energy — a good time for any extra work that needs power.
