Total	542	63	432	110	176		112.4

Origin sun (= sunshine duration): MeteoSwiss

Legend:

Snow cover
Snow cover has been recorded since the winter of 2024/25.
Snow cover in days is calculated from the degree of snow cover (0..100%) and the duration.

Photovoltaic/solar energy system ALS24 (Hasle-Rüegsau, Emmental)

The panels are partially shaded by two large trees during the winter months (loss of up to 20% of sunny days). At high irradiation, the inverter limits at 7 kW. Without these two restrictions, higher yields would result.
