SERVICE
Photovoltaics Switzerland: your solar system from a specialist company
A direct specialist company for photovoltaics in German-speaking Switzerland: consultation, planning, installation and registrations from one hand – manufacturer-independent and Swissolar-certified.
Photovoltaics Switzerland – direct from the installer
ecoEn plans and installs photovoltaic systems in German-speaking Switzerland – as a direct specialist company, not a brokerage platform. Consultation, planning, installation and registrations with the grid operator and Pronovo come from one hand. If you'd like to have a solar system installed, you'll typically receive a free, no-obligation quote with all items from us within a few days.
Our team works in the City and Canton of Zurich as well as in the cantons of Aargau, Zug, Schwyz, Thurgau and Schaffhausen. Over 150 completed systems and more than ten years of experience stand behind every quote – from single-family homes to apartment buildings to commercial roofs.
Swissolar certified
Your photovoltaics partner in Switzerland
ecoEn plans and installs photovoltaic systems as a direct specialist company – from the first consultation through installation by our own team to registration with the grid operator and Pronovo. We work manufacturer-independently: we choose modules, inverters and storage to suit your roof, consumption and budget, and every item is shown transparently in the quote.
Why photovoltaics with ecoEn?
How your photovoltaic project works
From the first question to a running system, you have one point of contact with us. The process is the same for every project – the details depend on your roof.
- Initial consultationFree and without obligation: we discuss your roof, electricity consumption and goals – by phone, WhatsApp or on site.
- Site visitWe check the roof, meter cabinet and shading directly on site. That way, the quote is based on real figures instead of assumptions.
- QuoteYou receive a transparently itemised quote with all items – typically within a few days of the site visit.
- InstallationOur installation team installs the modules, inverter and electrics. Roof installation for a single-family home usually takes a few working days.
- Registration & incentivesConnection application to the grid operator, notification to the municipality and one-off feed-in incentive with Pronovo: we take care of the administration.
- Handover & operationAcceptance with safety certificate, monitoring set-up and handover – after that, we remain your point of contact.
What does a photovoltaic system cost?
Cost depends mainly on system size, roof covering and the condition of the household electrics. The following guideline prices per kilowatt of capacity (kWp) serve as orientation:
| System size | Guideline price per kWp | Typical use |
|---|---|---|
| 3–5 kWp | CHF 2,400–3,000 | small roofs, partial coverage |
| 5–10 kWp | CHF 2,100–2,700 | classic single-family home |
| 10–15 kWp | CHF 2,000–2,500 | larger single-family home, with heat pump or EV |
| 15–30 kWp | CHF 1,800–2,300 | large single-family roofs, small apartment buildings |
| from 30 kWp | CHF 1,500–2,000 | apartment buildings, businesses |
Guideline prices as of July 2026, turnkey incl. installation and VAT, before incentives. The binding figure is the individual quote.
On top comes the federal one-off feed-in incentive of currently around CHF 360 per kWp for roof-mounted systems (up to 30 kWp, as of July 2026; Pronovo's current rates apply) – plus the tax deduction and any municipal contributions. Worked examples and all price factors can be found in the complete cost guide.
Our solar calculator reads your roof from the official federal data (sonnendach.ch) and shows guideline figures for cost, incentives, yield and payback in two minutes.
On-roof or roof-integrated?
On-roof is the standard and the cheaper option: the modules are mounted above the existing covering, which works on most tiled, metal and flat roofs. Roof-integrated systems replace the roof skin and blend visually into the roof – they cost more per kWp, but the calculation changes as soon as a roof renovation is due anyway. At the site visit, we look at both and tell you honestly which option suits your roof. The same goes for components: we quote standard and premium lines transparently side by side, so you can see the difference instead of guessing it.
If appearance matters or the roof is being re-covered anyway, it's worth a closer look: on the roof-integrated solar page, we show four completed roof-integrated systems, when the surcharge pays off and why the federal government subsidises integrated systems more than roof-mounted ones.
Getting more out of solar power: storage, heat pump, EV
A photovoltaic system pays off all the better the more electricity you use yourself. Battery storage shifts solar power into the evening, a heat pump turns it into heat, and a wallbox preferably charges the EV when the roof is producing. Because we plan all trades together from the start, we match the components to each other – one system, one point of contact.

Solar systems in your region: local cost, incentives and feed-in tariff
Incentives and feed-in remuneration differ from canton to canton and from utility to utility. For our core regions, we've summarised figures, grid operator tariffs and real references on separate pages:

What our quote includes – and what it doesn't
The most common worry before signing isn't the price but the question of what gets added at the end. That's why we show both.
Included: planning and design, materials (modules, inverter, mounting system, cabling), scaffolding, installation, the electrical connection by our own specialist company, commissioning and measurement, registration with the grid operator and the incentive application to Pronovo – we submit it for you.
Shown separately: anything added in individual cases appears as its own item in the quote, not in a lump sum. The most common case: if the existing meter distribution board – the fuse box – is not suitable for the system and needs to be adapted, we invoice this separately. Depending on the property, official fees and work provided by the client may also apply.
Payment in stages, linked to project progress. Under our terms and conditions (AGB), that's 30% on placing the order, 50% on delivery of the main components and 20% after commissioning and acceptance. We agree different terms on a project basis; the arrangement in your quote always applies.
Who is liable for what
After the company bankruptcies in the Swiss solar industry, this is the question that counts in the end – and it has three different answers:
- Product and performance warranties lie with the manufacturer of the modules, inverter and storage. A manufacturer's warranty is only ever as reliable as the manufacturer behind it – that's why, when choosing products, we also consider who will still be reachable if something goes wrong.
- The installation warranty lies with us: installation, electrical work, commissioning. That's the part we honour directly.
- Business liability insurance: as an installation company, we carry liability insurance.
In the event of a fault, you have one point of contact – us – regardless of whose component is affected.
