In Küsnacht ZH, Werke am Zürichsee are your grid operator. Fed-in solar electricity is remunerated in 2026 according to the reference market price, currently at the statutory minimum remuneration of 6.00 Rp./kWh (up to 30 kW), as the market price is lower. There are no cantonal PV incentive contributions – but the municipality of Küsnacht incentivises roof-integrated systems and saltwater batteries, plus the federal one-off feed-in incentive and tax deduction. (As of: July 2026)
Key points in brief
- The grid operators in Küsnacht are Werke am Zürichsee – they determine your feed-in tariff.
- Küsnacht provides incentives itself: roof-integrated PV with CHF 50 per MWh of annual production, saltwater batteries with CHF 300/kWh.
- The tax deduction weighs particularly heavily with Küsnacht incomes; on the other hand, there are no direct cantonal PV incentives.
- Single-family home guideline value: around CHF 22,000–30,000 for 10 kWp; on the Gold Coast, larger systems and batteries are above-average in frequency.
- Near the lake and on exposed hillside locations, aesthetics and townscape count – there are in-roof and anti-glare solutions for this.

How is your solar electricity remunerated in Küsnacht?
Via Werke am Zürichsee, which also supply Zollikon and Erlenbach. Since the new Electricity Act, the market price model applies: the federal quarterly averaged reference market price is remunerated. This is currently low – at around 3.90 Rp./kWh in the second quarter of 2026. Therefore, the statutory lower limit of 6.00 Rp./kWh applies for systems up to 30 kW, and this is currently the authoritative value.
The Werke am Zürichsee tariff sheet does not list a separate surcharge for the guarantee of origin – check the current publication in case this changes. For planning, this means: calculate over the annual average, keep self-consumption high. The complete classification: Werke am Zürichsee tariff article.
What incentives do you receive in Küsnacht?
Küsnacht is more interesting here than many municipalities. The basis is provided by the federal government with the one-off feed-in incentive (EIV): around CHF 360 per kW for attached, CHF 400 per kW for roof-integrated systems (under 30 kW). However, the actual lever in Küsnacht is the tax deduction – the investment on an existing building is deductible, and the effect is large with the marginal tax rates usual here.
The new "Climate, Energy and Green Space 2026–2029" incentive regulations have applied since 1 January 2026 (framework credit CHF 2 million; the predecessor programme was exhausted in October 2024). Targeted support is provided for solutions that protect the townscape: in-roof systems with CHF 50 per MWh and year – calculated over the assumed lifespan of 15 years, around CHF 675 per kWp (10 kWp: CHF 6,750) – and facade systems with CHF 40 per MWh and year (around CHF 540 per kWp). Classic on-roof systems do not receive a municipal contribution, systems on new buildings only as facade systems. When it comes to the battery, Küsnacht consciously incentivises lithium-free technology: saltwater batteries CHF 300 per kWh, redox flow CHF 200, other non-lithium-based batteries CHF 250 per kWh – a rare constellation on the Gold Coast. Maximum CHF 40,000 per project; the application must be submitted before construction begins.

What does a solar system cost in Küsnacht?
The price depends on the roof, not the postcode – in Küsnacht, however, it is noticeable that the roofs are larger on average and batteries are more often part of it:
| System size | Cost guideline (turnkey, incl. VAT) | Suitable for |
|---|---|---|
| 10 kWp | CHF 22,000–30,000 | medium single-family home |
| 15 kWp | CHF 27,000–37,000 | larger single-family home, heat pump + e-car |
| 20–25 kWp + battery storage | from ~CHF 45,000 | Villa, high self-consumption, emergency power |
Guideline values incl. installation and connection, as of: July 2026, non-binding; the individual quote is decisive. Details: Solar system costs and battery storage guide.
Küsnacht on the Gold Coast: What counts with lake location and townscape
Küsnacht is located on the right bank of Lake Zurich, with hillside locations between the lake and Forch. We see two things here more often than elsewhere: representative properties with demands on aesthetics – and plots in locations that characterise the townscape, where the authority looks more closely at the roof design.
Both are solvable. Those who do not want to see elevated modules choose a roof-integrated in-roof system – which Küsnacht even additionally incentivises; against reflections in exposed locations, there are modules with anti-glare coating. There is no general rule as to whether a system is allowed in a location worthy of protection – the municipality assesses this on a case-by-case basis. Whether your roof has enough area and sun is shown by a first approximation on sonnendach.ch; the fine details are clarified by the site visit.
On In der Teien in Küsnacht, we realised a system in 2023 that is exactly typical for this clientele: around 24.7 kWp on a south-facing roof, combined with a salt battery storage (Salidomo 18, about 18 kWh) and emergency power output – a battery that manages without lithium and cobalt. What was then considered a pure sustainability decision now additionally meets the incentive logic of the municipality, which supports exactly such saltwater batteries. The system is partially island-capable, so the house remains supplied in the event of a grid failure. Such larger, well-equipped systems are rather the rule than the exception in Küsnacht.

Werke am Zürichsee, which also supply Zollikon and Erlenbach. The remuneration follows the reference market price with a minimum remuneration of 6.00 Rp./kWh up to 30 kW – currently the authoritative value.
Does Küsnacht provide incentives for solar systems and batteries?

Is a solar system worth it in Küsnacht?
In most cases, yes. In addition to self-consumption and the one-off feed-in incentive, the tax deduction has a strong effect in Küsnacht because it grows with the marginal tax rate; plus there are the municipal incentives for integrated systems.
Are solar systems allowed in locations worthy of protection?
There is no general answer – the municipality assesses this on a case-by-case basis. Roof-integrated in-roof systems and discreet modules significantly increase the chances of approval.
What does a system with battery storage cost in Küsnacht?
For a larger system with a battery, the guideline values start from around CHF 45,000 (as of July 2026, without obligation). The exact price depends on the roof, system size and battery capacity – the municipal battery incentives reduce the net costs.
