Energy self-sufficiency Zurich: your integrated energy system
Photovoltaics, battery storage, heat pump and wallbox as a coordinated system – for more self-consumption and gradually more independence from the grid.
Energy self-sufficiency Zurich – your integrated energy system
ecoEn plans photovoltaics, battery storage, heat pump and wallbox as a coordinated system – for more self-consumption and gradually more independence from the grid. We calculate transparently how far this can realistically be achieved for your house.
A sensible starting point is usually the photovoltaic system, followed by storage, heat pump and wallbox – depending on budget and priorities. We plan the system from the start so that later extensions fit in cleanly.
Swissolar certified
Your partner for an integrated energy system
ecoEn plans photovoltaics, battery storage, heat pump and wallbox as an overall system – not as loose individual parts. This increases your self-consumption and makes you more independent from the grid step by step. We calculate how far this can realistically be achieved for your house based on consumption, roof and budget.
Why an integrated energy system?
How your energy system is created
From the first conversation to the final expansion stage – the process follows your priorities.
- InventoryConsumption, roof, heating and vehicle: we get a picture of your starting situation.
- PrioritisationTogether, we decide what comes first – usually the photovoltaic system – and what follows later.
- Concept & quoteA system proposal with a realistic assessment of self-consumption and self-sufficiency rate.
- Implementation in stagesInstallation of the individual components – individually or as a package, depending on your plans.
- Control & handoverSet-up of energy management and handover – after that, we remain your point of contact.
What does an integrated energy system cost?
The scope determines the price: a photovoltaic system alone costs significantly less than a system with storage, heat pump and wallbox. The guideline prices of the individual components serve as orientation – they correspond to our respective cost guides:
| Component | Guideline (single-family home) | Note |
|---|---|---|
| Photovoltaic system | CHF 12,000–37,000 | depending on size, turnkey, before incentives |
| Battery storage (10 kWh) | approx. CHF 8,000–12,000 | CHF 800–1,200 per kWh of usable capacity, installed |
| Heat pump (air-to-water) | CHF 45,000–60,000 | SwissEnergy reference values, incl. installation |
| Wallbox | CHF 2,500–5,000 | Device plus installation, depending on cable route |
Guideline values as of July 2026, before incentives – the individual quote is decisive. You don't have to implement everything at the same time; most start with the photovoltaic system and extend later.
Details on each component: solar system costs, battery storage costs, heat pump costs and wallbox costs. If the storage is installed together with the solar system, the total cost falls – see Solar system with storage: package costs.
Further guides on the energy system
The building blocks at a glance
An integrated energy system usually consists of a photovoltaic system, battery storage, a heat pump and a wallbox. You don't have to implement everything at the same time – what matters is that the planning is designed for the overall system from the start.
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.
