Solar in Zug: installed base, potential and electricity price 2027

  1. Self-consumption

    What a self-consumed kWh is worth in Zug

    On the standard tariff of WWZ Energie AG, a purchased kWh costs 17.96 ct in 2027 excluding fixed and metering fees. That is roughly what every kWh of solar power saves when it is used in the house instead of being exported. The total price is 0.73 ct below last year (21.88 ct).

    Exported power is paid at the quarterly reference market price; since 2026, systems below 30 kW are guaranteed a minimum of 6 ct/kWh. In Zug, self-consumed power is therefore worth up to 3.0 times as much as exported power — which is why the share of solar power used in the house matters most.

  2. Winter power

    How much solar power Zug delivers in winter

    Suitable roofs in Zug could produce 120.2 GWh of solar power per year, 25% of it between October and March. Adding façades raises the potential to 165.7 GWh and the winter share to 28%: vertical surfaces make better use of the low winter sun.

    For a house with a heat pump, this winter share is what matters: demand is highest in winter and self-consumption is most valuable. Whether a flatter or steeper layout pays off on your roof only becomes clear in the site assessment.

  3. Uptake

    How far Zug has come with solar

    The federal plant register lists 464 photovoltaic systems in Zug with a combined 19.4 MW. Since January 2025, 76 systems with 2.7 MW have been added. The register covers all systems above 30 kVA, subsidised systems and voluntarily registered small systems; new systems often appear with a delay. Per resident that is 605 watts — rank 11 of 11 municipalities in the Canton of Zug.

Figures with sources

Solar in Zug: cost, size, storage.

Three questions decide almost every project before a roof is ever measured. Here they are with source and date, so it stays clear what each figure rests on.

  1. Costs

    What a system costs

    Example: 5–10 kWp rooftop PV: CHF 13,500–27,000. Incl. 8.1% VAT, before incentives and tax deductions, without a battery. Calculated from the SFOE median of CHF 2,497/kWp: the range reflects different system sizes. A market comparison, not a quote.

    Roof renovation, structural reinforcement and replacement of the meter cabinet are not included. Roof access, electrical work and planning can change the price. Your specific quote follows the property assessment.

    Costs with calculation and sources

  2. Sizing

    Single-family home: the realistic size

    A typical household using around 4,000 kWh per year needs roughly 25 m² of module area (Swissolar, February 2024). As a starting figure, global irradiation in Canton Zug is around 1120 kWh/m² per year. Whether that works on your roof in Zug depends on orientation, pitch and shading — not on the floor plan.

    Two federal bonuses explicitly do not apply to a single-family home: the winter electricity bonus requires at least 100 kW, and the tilt bonus at least 75 degrees of pitch. Neither applies to an ordinary pitched roof. Counting on them makes the business case look better than it is.

    Clarify notification and permission before installation

  3. Storage

    Battery storage and self-consumption

    Battery storage earns its money through self-consumption: it shifts solar power from midday into the evening. With WWZ Energie AG, every kWh shifted this way is worth 17.96 ct instead of a feed-in payment of at least 6 ct — up to CHF 120 per 1,000 kWh a year. Whether that covers the battery over its lifetime depends on your evening consumption.

    Since 1 January 2025, an association for self-consumption (ZEV) may also use the existing connection lines. This makes apartment buildings and neighbourhood setups considerably cheaper, as no dedicated line is required. In Zug, the connection conditions are set by WWZ Energie AG.

Swiss facts

Applies to residential and commercial properties.

One-time remuneration
Federal support depends on system type and size band. Vigorek clarifies which remuneration rate applies to your property and how it interacts with canton and grid operator.
Storage as a system decision
A battery only pays off when it fits your consumption and home technology. We assess it as part of the overall plan — not as a late upsell.
Realistic payback
We calculate with ranges instead of wishful numbers: self-consumption, remuneration and tariff logic together give a realistic picture of your economic return.

Economics

What does your solar system save?

We map self-consumption, feed-in tariff and payback for your property — so you see early what the system realistically returns.

Proof

How sound planning becomes visible.

Our quotes are not built from flat packages, but from checked data, technical pre-assessment and clearly itemized positions.

  1. Planning basis

    Official data as the first cross-check

    Roof potential, irradiation and addresses are checked against GeoAdmin and BFE Sonnendach: the same datasets used by federal and cantonal bodies.

  2. Property review

    Final quote based on verified data

    The initial estimate gives realistic orientation. For the final quote, we capture roof areas, access and technical conditions through a 3D survey (drone) and on-site review — precise, not based on satellite assumptions.

  3. Electrical

    Coordination by licensed professionals

    From electrical planning through protection equipment to grid registration: all safety-critical steps are carried out by licensed electrical professionals, in-house or through vetted partners.

  4. Quote

    Itemized instead of a flat package

    Every line item is shown individually instead of hidden in a flat package — so variants and ranges stay traceable from the start.

Regional clarification

Not every system follows the same logic in Zug.

In Switzerland, permits, grid operator, metering concept and incentive path always depend on the property, municipality and canton. These are exactly the points clarified early before a quote becomes binding.

That avoids a generic promise and creates a well-founded assessment that fits the region and the building.

Municipality check

Solar system in Zug: what matters locally

Single-family homes, agricultural buildings and smaller commercial roofs need different mounting systems. Before quoting, we review roof membrane, cable routing, inverter location and possible scaffolding logic.

Zug belongs to Canton Zug. We therefore combine the local roof assessment with cantonal requirements for subsidies, permits, grid connection and documentation.

Roof potential

Canton Zug guideline: approx. 1120 kWh/m² global irradiation per year.

Grid & utility

Grid operator in Zug according to ElCom: WWZ Energie AG. Metering concept and registration are clarified before execution.

Permit

Solar obligation for replacement new buildings (min. 10 W/m² energy reference area, max 30 kW). Standard notification procedure for existing buildings. Ägerisee region: alpine special rules possible.

Subsidies & taxes

Solar obligation since 1.1.2023: All replacement new buildings min. 10 W/m² energy reference area, max 30 kW. No cantonal PV top-up; the federal one-time payment via Pronovo and the full tax deduction are decisive. WWZ remunerates at the BFE reference market price (quarterly) plus an HKN bonus.

Services with a real focus on Zug

The key services, tailored directly to Zug and the local requirements in your region.

Regional service

PV Installation Zug – Roof & Electrical

Canton Zug combines high innovation density with a strong sustainability agenda. WWZ (Werke Zug) has remunerated feed-in at around 8.5 Rp./kWh since July 2025; from 2026 remuneration tracks the BFE reference market price (quarterly, statutory minimum 6 Rp./kWh up to 30 kW) plus HKN. Many companies in Crypto Valley use solar systems as part of their ESG strategy – and expect installation quality matching international headquarters standards. Compact geography and high building density make ZEV and LEG models particularly economical.

Regional service

Flat-Roof Photovoltaics Zug – Loads, Roof Protection and Mounting

In Canton Zug, flat roofs on commercial buildings and company headquarters are the focus – especially international headquarters with sustainability requirements. WWZ has remunerated feed-in at around 8.5 Rp./kWh since July 2025; from 2026 remuneration tracks the BFE reference market price (quarterly, statutory minimum 6 Rp./kWh up to 30 kW) plus HKN. The high density of smart energy solutions and the blockchain ecosystem create demand for intelligent self-consumption management on flat roofs with monitoring and data connectivity.
