   Self-consumption

   What a self-consumed kWh is worth in Hüniken

   On the standard tariff of Genossenschaft Elektra Äusseres Wasseramt EAW, a purchased kWh costs 21.30 ct in 2027 excluding fixed and metering fees. That is roughly what every kWh of solar power saves when it is used in the house instead of being exported. The total price is 1.65 ct below last year (30.16 ct).

   Exported power is paid at the quarterly reference market price; since 2026, systems below 30 kW are guaranteed a minimum of 6 ct/kWh. In Hüniken, self-consumed power is therefore worth up to 3.6 times as much as exported power — which is why the share of solar power used in the house matters most.

   Winter power

   How much solar power Hüniken delivers in winter

   Suitable roofs in Hüniken could produce 1.7 GWh of solar power per year, 29% of it between October and March. Adding façades raises the potential to 2.2 GWh and the winter share to 30%: vertical surfaces make better use of the low winter sun.

   For a house with a heat pump, this winter share is what matters: demand is highest in winter and self-consumption is most valuable. Whether a flatter or steeper layout pays off on your roof only becomes clear in the site assessment.

   Uptake

   How far Hüniken has come with solar

   The federal plant register lists 12 photovoltaic systems in Hüniken with a combined 209 kW. Since January 2025, 1 systems with 12 kW have been added. The register covers all systems above 30 kVA, subsidised systems and voluntarily registered small systems; new systems often appear with a delay. Per resident that is 1,301 watts — rank 42 of 104 municipalities in the Canton of Solothurn.

   Costs

   What a system costs

   Example: 5–10 kWp rooftop PV: CHF 13,500–27,000. Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated from the SFOE median of CHF 2,497/kWp: the range reflects different system sizes. A market comparison, not a quote.

   Roof renovation, structural reinforcement and replacement of the meter cabinet are not included. Roof access, electrical work and planning can change the price. Your specific quote follows the property assessment.

   Sizing

   Single-family home: the realistic size

   A typical household using around 4,000 kWh per year needs roughly 25 m² of module area (Swissolar, February 2024). As a starting figure, global irradiation in Canton Solothurn is around 1150 kWh/m² per year. Whether that works on your roof in Hüniken depends on orientation, pitch and shading — not on the floor plan.

   Two federal bonuses explicitly do not apply to a single-family home: the winter electricity bonus requires at least 100 kW, and the tilt bonus at least 75 degrees of pitch. Neither applies to an ordinary pitched roof. Counting on them makes the business case look better than it is.

   Storage

   Battery storage and self-consumption

   Battery storage earns its money through self-consumption: it shifts solar power from midday into the evening. With Genossenschaft Elektra Äusseres Wasseramt EAW, every kWh shifted this way is worth 21.30 ct instead of a feed-in payment of at least 6 ct — up to CHF 153 per 1,000 kWh a year. Whether that covers the battery over its lifetime depends on your evening consumption.

   Since 1 January 2025, an association for self-consumption (ZEV) may also use the existing connection lines. This makes apartment buildings and neighbourhood setups considerably cheaper, as no dedicated line is required. In Hüniken, the connection conditions are set by Genossenschaft Elektra Äusseres Wasseramt EAW.
