In Thalwil, feed-in is the responsibility of EKZ. The quarterly reference market price of the Confederation is remunerated, but at least 6.0 Rp./kWh for systems up to 30 kW; anyone who assigns the guarantee of origin (GO) to EKZ receives up to an additional 3.0 Rp./kWh. Because the reference value is currently low, the minimum remuneration takes effect in practice. There are no cantonal PV incentive contributions – but there is the one-off feed-in incentive (EIV) from the Confederation and the full tax deduction. (As of: July 2026)
Key points in brief
- Your grid operator in Thalwil is EKZ, responsible for large parts of the left bank of the lake.
- Minimum remuneration 6.0 Rp./kWh up to 30 kW; the guarantee of origin brings up to 3.0 Rp./kWh extra – but only if assigned.

- You can check exactly by postcode on energiefranken.ch whether the municipality of Thalwil pays an additional contribution – 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).

How is your solar power remunerated in Thalwil?
In Thalwil, EKZ is your grid operator. Since the new Electricity Act, they remunerate the fed-in solar power according to the quarterly averaged reference market price of the Confederation. At the lower end, the remuneration is secured: For systems up to 30 kW, the minimum remuneration of 6.0 Rp./kWh applies (6.2 Rp. up to 150 kW without self-consumption).
For the guarantee of origin (GO), the active step is worth it: If you assign it to EKZ, they remunerate it with up to an additional 3.0 Rp./kWh – this does not happen automatically. For expectation management: The reference market price was around 3.9 Rp./kWh in the second quarter of 2026, i.e. below the minimum remuneration – currently the 6 Rappen apply. The complete system is explained in the EKZ tariff article. Calculate over the annual average and keep self-consumption high.
What incentives do you get in Thalwil?
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 on existing buildings are deductible from state and federal taxes. There are no direct cantonal PV incentives in the Canton of Zurich. You can check exactly by postcode on energiefranken.ch whether Thalwil runs its own municipal programme – budgeted, with application before the start of construction. We take over this clarification with every quote.
The current regulations of Pronovo or the municipality are authoritative. As of: July 2026.
How much does a solar system cost in Thalwil?

| 6 kWp | CHF 16,000–21,000 | smaller single-family home |
| 10 kWp | CHF 22,000–30,000 | typical single-family home with heat pump/EV |
| with battery (10 kWp + ~10 kWh) | surcharge CHF 7,000–11,000 | high self-consumption, backup power desired |
Guideline values incl. installation and connection, as of: July 2026, non-binding; the individual quote is decisive. Details: Solar system costs and 10 kWp system.
Which roofs characterise Thalwil – between lake and slope?
Thalwil is densely built-up and sought-after as a residential location: below by the lake and around the train station are apartment buildings, above them single-family home and lake view neighbourhoods stretch up the slope towards Gattikon. Completely different roofs thus meet in a tight space.
In the lake view and hillside locations, the orientation is often not ideally to the south – but with careful layout, these roofs deliver reliably. In densely built-up neighbourhoods, shading from neighbouring buildings is also an issue that we check in advance. In townscape-sensitive locations, well-integrated or roof-integrated systems are often the calmer way. On the apartment building flat roofs, a self-consumption community (ZEV) is worthwhile. A first reference point for your own roof is provided by sonnendach.ch.
In Thalwil, shading is often the real hard nut to crack – densely built neighbourhoods, trees, neighbouring houses. We therefore record the shading exactly before the quote, instead of sugar-coating it. If it is under control, even a hillside roof with a lake view delivers solid yields. And we take the GO to EKZ along as standard – otherwise it tends to get left behind.
Frequently asked questions
Which grid operator is responsible for Thalwil?
EKZ, responsible for large parts of the left shore of the lake. They set the feed-in tariff and handle the grid connection. Remuneration follows the market price model with a 6.0 Rp./kWh minimum remuneration up to 30 kW.
How much do I get for fed-in electricity?
The base is the quarterly reference market price; a minimum of 6.0 Rp./kWh applies up to 30 kW. For the guarantee of origin, EKZ pays up to 3.0 Rp./kWh extra, provided you assign it. Because the market price is low in 2026, the minimum remuneration currently applies.
My roof has shading – is solar still worth it in Thalwil?
Often yes, provided the shading is limited and the system is designed for it. We record it exactly before the quote and dimension the modules accordingly. Nothing is kept quiet.
Do I get cantonal incentives in Thalwil?
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 a solar system worth it in Thalwil?
In most cases, yes. Profitability comes from self-consumption, the one-off feed-in incentive and the tax deduction – not from feed-in alone.
How much does a 10 kWp system cost in Thalwil?
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.
