How quickly does Ampere Dynamic respond after my enquiry?

We respond within 2 working days with an initial assessment of your project. No automated first contacts: direct feedback from a specialist who can evaluate your situation.

Which building types and roof forms are suitable for solar installations?

Flat roofs, trapezoidal roofs, corrugated roofs, facades and parking canopies are all suitable. Lightweight modules (up to 60% lighter than conventional glass modules) are available for roofs with limited load-bearing reserves. As part of our feasibility study, we assess statics, roof pitch, orientation and shading. For more detail, see Module and Roof Types.

Economics and Investment

For industrial and commercial businesses, economic viability is the primary decision factor.

Is a large-scale PV system worthwhile for my business?

For businesses with annual electricity consumption of 200’000 kWh or more, a large-scale system is clearly economically viable. The key factors are your load profile, self-consumption share and available roof areas. Through targeted self-consumption optimisation, well-planned systems achieve rates of 70–90%. This maximises the economics and accelerates payback significantly. Contact us for an individual economic calculation. Response within 2 working days.

How quickly does the investment pay off?

Commercial solar power plants in Switzerland typically pay for themselves within 4–6 years. This timeframe depends on system size, self-consumption share, available subsidies and local electricity costs. As part of our consulting process, we create an individual amortisation calculation for your specific situation.

What is peak shaving and how does it reduce my energy costs?

Peak shaving refers to the targeted reduction of load peaks using a battery storage system. It detects approaching load spikes and discharges before the grid connection is expensively burdened. Industrial and commercial businesses with high demand charge components in their grid fee invoices save around CHF 10’800 a year per 100 kW of peak capped (median demand charge 2026, ElCom). See Battery Storage for further details.

Is repowering worthwhile for existing installations?

Replacing ageing modules and inverters on an 8 to 15-year-old installation increases yield by 20–40% and pays for itself in 2–4 years. The investment is 30–50% less than a new build, as the roof structure, grid connection and permits largely remain in place. Inverters typically last around 15 years and are often the first trigger. See Repowering for details.

Shouldn’t I wait until prices fall further?

Whoever invests today benefits immediately from energy cost savings. Every month of delay means foregone savings. Current one-time subsidies (KLEIV/GREIV) are attractive, with no guarantee of better conditions in the future. Our economic analysis shows you the optimal investment timing for your situation.

Technology and Implementation

From the first contact to turnkey handover, every project follows the proven Ampere Method.

How does a project run from enquiry to commissioning?

Typical projects take 6–12 months from enquiry to commissioning. The phases are: needs analysis and feasibility study, engineering and planning, construction and installation, grid connection and commissioning. Ampere Dynamic manages all steps as general contractor from a single source. Zero operational disruption is a binding requirement throughout.

Does the installation disrupt our operations?

No. We carefully plan installation work and coordinate the schedule closely with you so that your business operations can continue undisturbed. Zero operational disruption is a binding requirement for us, not a statement of intent.

What is a ZEV and how does it work?

A Zusammenschluss zum Eigenverbrauch (ZEV, collective self-consumption scheme) allows multiple consumers on the same site to share solar power as a single grid metering point. The vZEV (virtual ZEV) has connected multiple neighbouring plots on the same service line through the grid operator’s smart meters since 1 January 2025, without using the distribution grid. This raises the self-consumption share from 30–40% to up to 70–90%. See ZEV and LEG for further details.

What is an LEG and how does it differ from a ZEV?

A Lokale Elektrizitätsgemeinschaft (LEG, local electricity community) has allowed the shared use of renewable energy at neighbourhood or municipal level since 1 January 2026, across multiple grid metering points. It is particularly suitable for industrial and commercial parks with several properties. Economically, ZEV internal prices of 15–22 Rp./kWh are achievable, compared with 3.9–10.3 Rp./kWh for grid feed-in (reference market price for solar electricity per quarter in 2026).

What charging infrastructure does Ampere Dynamic offer for electric vehicles?

Ampere Dynamic installs charging infrastructure with 10 to 200+ charging points and charging capacities of 22 kW to 400 kW per point. The offering includes integrated load management, PV truckports and EMS integration for complete sector coupling. The flagship project Hugelshofer (1’001 kWp, 28 charging points, 400 kW DC, Swiss Logistics Award 2024) demonstrates the achievable potential. See E-Mobility.

How can I market surplus solar power?

Surplus solar power can be marketed in several ways: grid feed-in (3.9–10.3 Rp./kWh per quarter in 2026), internal ZEV distribution (15–22 Rp./kWh), spot market trading, power purchase agreements (PPAs) for installations from approximately 3 GWh, and the sliding market premium (GMP) for full feed-in. Ampere Dynamic manages the active portfolio. See Energy Marketing for details.

Which modules are suitable for flat roofs, trapezoidal roofs or facades?

Conventional glass modules are suitable for all common roof types. Lightweight modules (up to 60% lighter) are available for flat roofs with limited load capacity. Bifacial modules maximise yield on facades and steep installations by utilising rear-side reflection, achieving up to 25% additional yield in suitable locations. See Module and Roof Types and Vertical PV.

Financing and Subsidies

Swiss subsidy programmes significantly reduce the initial investment. The application must be submitted correctly and on time.

What financing options are available?

We structure the right financing solution for your situation: self-investment, leasing or contracting. With self-investment, you receive all subsidies directly. With leasing, instalments typically remain below energy savings, with ownership transferring at the end. With contracting, you pay only for produced electricity, without capital outlay. Ampere Dynamic evaluates and structures the appropriate solution. See Financing.

What subsidies are available in Switzerland?

The main federal subsidies are the one-time payments KLEIV (below 100 kWp) and GREIV (from 100 kWp), supplemented by cantonal and municipal programmes. We handle the entire subsidy application process from A to Z so that no subsidy franc is lost. See Subsidies for more details.

Which new subsidy bonuses apply since 2025?

Since 1 January 2025, two new bonuses apply to KLEIV/GREIV under the Mantelerlass. The tilt angle bonus only applies to system parts tilted at 75 degrees or more: +CHF 400/kW for building-integrated modules (BIPV) or +CHF 200/kW for attached and freestanding modules; the mounting type sets the rate, and the same system part never gets both. The parking area bonus (+CHF 250/kW) applies to systems from 100 kWp over a permanent, previously uncovered car park. From 1 January 2026, the winter electricity bonus applies to installations from 100 kWp producing more than 500 kWh per kW during the winter half-year. It is an alternative to the tilt angle bonus, not an addition to it.

Are there specific subsidy programmes for e-truck charging infrastructure?

Yes. The «in charge» sector programme run by ASTAG and the Swiss Federal Office of Energy (SFOE) subsidises charging infrastructure for road transport SMEs with fewer than 250 employees at up to 40% of eligible costs, with a total budget of CHF 20 million. Larger companies with a net-zero roadmap can file their own application with the SFOE under the Climate and Innovation Act (KlG). It covers up to 50% of eligible costs, but only for novel technologies and processes; whether a charging park qualifies is assessed by the SFOE case by case.

Does my company need to draw up a net-zero roadmap?

No, the roadmap is voluntary. Since 2025, however, the Climate and Innovation Act (KlG) requires every company, whatever its size, to reach net-zero emissions by 2050 at the latest (Art. 5 KlG). If you want KlG funding, you need a roadmap. A published climate report is required only of listed companies, banks and insurers with 500 or more full-time employees (Art. 964a ff. CO). PV, battery storage and e-mobility reduce the direct and indirect emissions that the roadmap accounts for. Ampere Dynamic supports you in planning an energy strategy on the path to net zero.

Service and Operations

A solar installation is infrastructure with an operating life of 25–30 years. Proactive service secures the economics over the entire operating period.

What maintenance and service does Ampere Dynamic offer?

For maximum economic performance, we offer three service tiers (Basic, Plus, Prime): 24/7 remote monitoring with immediate alerts for deviations, fast support and proactive maintenance with regular inspections, thermography and performance reports. See Service and Operations.

What happens in the event of a fault or performance drop?

The 24/7 remote monitoring detects deviations immediately and triggers an automatic alert. Critical faults are resolved within 2 working days. Proactive maintenance and regular thermography inspections prevent most faults before they have any measurable economic impact.

How long does a solar installation last?

PV modules are designed for an operating life of 25–30 years. Inverters typically last around 15 years and are replaced on schedule within the service contract or modernised as part of a repowering project. A well-maintained installation produces economically over its entire operating life.

Does Ampere Dynamic also offer service for battery storage and charging infrastructure?

Yes. Service and operations cover all technologies: PV installations, battery storage and EV charging infrastructure. Clients benefit from a single point of contact for their entire plant portfolio, including EMS optimisation and energy marketing.
