Battery storage Zurich: home batteries from a specialist company

Battery storage for Zurich and the surrounding area: planned manufacturer-independently, installed professionally – with a new solar system or as a retrofit.

Battery storage Zurich – planned by a specialist company

ecoEn plans and installs battery storage in and around Zurich – together with new systems or as a retrofit to your existing solar system. We work manufacturer-independently and have implemented various solutions, from compact home batteries to salt battery and backup power systems.

Storage shifts solar power from midday into the evening, increasing self-consumption. Whether and in what size it pays off for you depends on your consumption profile, feed-in tariff and incentives – exactly what we calculate transparently in the consultation.

Swissolar certified

Your partner for battery storage in Zurich

ecoEn plans and installs battery storage as a direct specialist company – manufacturer-independent, from compact home batteries to backup power solutions. Whether the storage comes with the new solar system or is retrofitted: sizing, installation and commissioning come from one hand.

Why ecoEn for your battery storage?

How your battery storage gets connected

From the first conversation to a running battery – the process is straightforward, the details depend on your system.

  1. Initial consultationFree and without obligation: we discuss your system, consumption and goals – from self-consumption to backup power.
  2. SizingSize comes before price comparison: we determine the capacity based on evening consumption and system size.
  3. QuoteTransparently itemised, with a clear statement of usable capacity – typically within a few days.
  4. InstallationTogether with the new solar system or retrofitted AC-coupled – by our own team.
  5. Commissioning & monitoringIntegration into energy management, instruction and handover – after that, we remain your point of contact.

What does battery storage cost?

For battery storage costs, the most reliable anchor is the installed price per usable kilowatt-hour: currently roughly CHF 800 to 1,200. Bare device prices from the internet are no basis for comparison – no battery runs without a professional connection.

Usable capacityInstalled guideline priceTypical case
~5 kWhCHF 4,000–6,000small household, low evening consumption
~10 kWhCHF 8,000–12,000common single-family home size
~15 kWhCHF 12,000–18,000large household, high evening/night consumption

Guideline values as of July 2026, before incentives and tax deduction – the individual quote is decisive. Smaller and backup-capable systems tend to be at the upper end, larger ones at the lower end.

It becomes significantly cheaper if the storage is installed together with the solar system rather than later. All price factors and examples: Battery storage costs in detail.

Getting more out of storage: solar system, wallbox, heat pump

Storage unfolds its value in combination: with the photovoltaic system as the source, a wallbox that preferably charges with solar power, and a heat pump that turns it into heat. Because we plan all trades together from the start, we match the components to each other.

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.

QUESTIONS

Questions about battery storage

Installed, a home battery currently costs roughly CHF 800 to 1,200 per kilowatt-hour of usable capacity – so a typical 10 kWh battery costs around CHF 8,000 to 12,000 (guideline values, as of July 2026, before incentives). It becomes cheaper if the storage is installed together with the solar system.
That depends on evening consumption, feed-in tariff, storage price and incentives. The more solar power you can shift into the evening, the more likely the storage pays off – we calculate this transparently for your situation.
Technically almost always – usually via a separate battery inverter on the AC side (AC coupling). Retrofitting is somewhat more expensive than installing together with the solar system; the fundamental question remains the same.
Only if it is explicitly designed for backup or emergency power – without this function, even a house with a full battery switches off in a grid outage. We have implemented several systems with backup power and advise you on the right solution.
Service life is measured in charge cycles and calendar years. Current lithium systems are designed for several thousand cycles; manufacturers usually guarantee around ten years or a defined remaining capacity.
Size comes before price comparison: evening consumption and system size are decisive. Between 10 and 15 kWh there are several thousand francs – capacity that an average household often doesn't even empty in the evening.
We work manufacturer-independently and choose the system based on the installation, consumption and inverter. The most frequently requested systems we offer are Huawei LUNA2000, BYD Battery-Box, Fenecon Home with emergency power and sonnenBatterie – all with LFP cells. From our projects: Huawei LUNA2000 with 14 kWh and backup power in Zollikon, Fenecon Home 30 in Affoltern am Albis and Home 20 in Watt (around 20 kWh each), and an 18 kWh salt battery in Küsnacht (as of September 2026).
Yes, as a niche: salt batteries do without lithium and cobalt, are non-flammable and easily recyclable, but need significantly more space and cost more per kilowatt-hour. According to the Swissolar battery monitor 2026, they account for around 1.2 percent of the Swiss market, and the number of suppliers is small. We implemented such a system in Küsnacht and clarify availability, warranty and service of the current system before quoting.
