Short answer

In Wädenswil, feed-in is the responsibility of Werke Wädenswil, the own municipal utility. Like all utilities, it remunerates the fed-in solar electricity in 2026 according to the federal government's quarterly reference market price, with the statutory minimum remuneration of 6 Rp./kWh for systems up to 30 kW as a lower limit – which currently applies because the market price is below it. There are no cantonal PV contributions, but there is the federal one-off feed-in incentive and the full tax deduction. (As of: July 2026)

Key points in brief

  • Your grid operator in Wädenswil is Werke Wädenswil – an independent municipal utility.
  • Base model as everywhere: the reference market price as the base, 6 Rp./kWh minimum remuneration up to 30 kW; any surcharge is stated in the local tariff sheet.
  • No direct cantonal PV incentive; the base is formed by the federal one-off feed-in incentive and the tax deduction.
  • You can check whether the City of Wädenswil pays an additional contribution exact to your postcode on energiefranken.ch – budgeted, application before the start of construction.
  • Cost guideline for a single-family home: around CHF 22,000–30,000 for 10 kWp (non-binding, the quote is decisive).
  • On the left bank of the lake, lake-view locations, hillside neighbourhoods and vineyard areas meet – orientation and the townscape deserve special attention.

How is your solar electricity remunerated in Wädenswil?

Wädenswil does not belong to the EKZ area, but is supplied via Werke Wädenswil, its own municipal utility. This changes nothing about the remuneration model: since the new electricity law, the federal government's quarterly averaged reference market price applies everywhere as a basis, secured by the statutory minimum remuneration of 6 Rp./kWh for systems up to 30 kW.

This lower limit is not a formality in 2026: the reference market price was around 3.9 Rp./kWh in the second quarter and thus below the minimum remuneration – so the 6 Rappen currently apply for the fed-in kilowatt hour. Whether Werke Wädenswil pay an additional green electricity surcharge or remunerate the guarantee of origin separately is stated in the current tariff sheet. We take this clarification off your hands as part of the quote. The system behind it is explained in the article Feed-in tariffs of municipal utilities; the actual lever is self-consumption anyway.

What incentives do you receive in Wädenswil?

The basis is the federal government: the one-off feed-in incentive (EIV) via Pronovo, around CHF 360 per kW for attached, CHF 400 per kW for in-roof systems (under 30 kW). For a 10 kW system, that is a good CHF 3,600.

In addition, there is the tax deduction: investments in existing buildings are deductible from state and federal taxes. There are no cantonal direct PV incentives in the Canton of Zurich. You can check whether Wädenswil runs its own municipal programme exact to your postcode on energiefranken.ch – budgeted, with an application before the start of construction. We take care of this clarification with every quote.

Which roofs characterise Wädenswil – from the lake view into the vineyards?

Wädenswil stretches from the lake up the hillside: below are the more densely built-up neighbourhoods and commercial areas on the lakeshore, above them residential areas with lake views, vineyards and – towards the heights – more rural districts like Schönenberg and Hütten. This staggering of altitudes decides the orientation and yield of every system.

On the hillsides with a lake view, the orientation is often inclined to the north-east or towards the lake – careful planning is worthwhile here so that the module layout is right; not every roof is ideal, but many deliver reliably if the inclination and shading are suitable. In townscape-sensitive locations and for lake-view properties, well-integrated or in-roof systems are often the more elegant way. On the commercial and apartment building flat roofs on the lakeshore, elevated systems make good use of the area. A first point of reference is provided by sonnendach.ch.

From practice

On the left bank of the lake, we often get the question of whether a system is even worthwhile if it is not perfectly south-facing. The honest answer: mostly yes – the orientation costs some yield, but self-consumption remains the decisive lever. With lake-view properties, we also pay attention to a calm, well-integrated appearance. And we clarify the Werke Wädenswil tariff in advance so that the calculation remains realistic.

Frequently asked questions

Which grid operator is responsible for Wädenswil?

Werke Wädenswil, its own municipal utility. They set the feed-in tariff and handle the grid connection. The remuneration follows the market price model with a 6 Rp./kWh minimum remuneration up to 30 kW.

How high is the feed-in tariff in Wädenswil?

The basis is the federal government's quarterly reference market price; for systems up to 30 kW, the lower limit of 6 Rp./kWh applies, which takes effect in practice in 2026. Whether Werke Wädenswil pay a surcharge is stated in the current tariff sheet.

Is a system worthwhile despite a lake-view location without a perfect south orientation?

In most cases, yes. A deviating orientation costs some yield, but self-consumption remains decisive. We check the inclination, shading and layout individually.

Do I get cantonal incentives in Wädenswil?

There is no direct cantonal PV incentive in the Canton of Zurich. What remains are the federal one-off feed-in incentive and the tax deduction; check for any municipal programme on energiefranken.ch.

Is an in-roof system sensible for lake-view properties?

Often yes – it blends more calmly into the roofscape, which is an advantage in townscape-sensitive locations. Whether in-roof or on-roof fits better depends on the roof, budget and requirements; we show both variants.

How much does a 10 kWp system cost in Wädenswil?

As a guideline, around CHF 22,000–30,000 turnkey (as of July 2026, non-binding). The exact price depends on the roof, mounting type and additional work.
