System step
In a few minutesInitial assessment
Your key details are enough: in a few minutes you receive a first orientation.

SOLAR · STORAGE · HEAT PUMPS
For roofs in Baltschieder, we combine PV installation, electrical work and commissioning into one aligned process instead of disconnected trades.
Services
PV system, heat pump, storage, wallbox and monitoring from one team. Every service is planned as part of a working energy system.

01 · Roof & facade
We review roof, structure, shading, cable routing, inverter and grid connection. Then we create a technically reliable quote.

Process
From first contact to commissioning, every system follows a clear process. We clarify roof, electrical work, incentives and expansion path completely. Only then do you receive a reliable quote. No site chaos, no wishful math.
System step
In a few minutesYour key details are enough: in a few minutes you receive a first orientation.
System step
Response within 24–48 hWe measure the roof by drone and clarify electrical work, regulations and the grid operator.
System step
A few days after the surveyYou see clear line items, realistic ranges and sensible options such as storage or a wallbox.
System step
After permit and grid-operator approvalWe coordinate execution, registration, acceptance and documentation until your system is reliably connected to the grid.
Swiss facts
One-time remuneration
Federal support depends on system type and size band. For many residential projects it is now a per-kW rate without a separate base amount; Vigorek clarifies which logic fits the property, canton and grid operator.
Storage as a system decision
A battery only makes sense when it fits the usage profile, the tariffs and the home technology. We assess this as part of the overall planning, 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.
Next step
As a next step, we map self-consumption, feed-in tariff, and payback for your property. That creates the first reliable estimate of its economic performance.
Proof
Our proposals are not built from flat packages, but from checked data, technical pre-assessment and clearly itemized positions.
Planning basis
Roof potential, irradiation and addresses are checked against GeoAdmin and BFE Sonnendach: the same datasets used by federal and cantonal bodies.
Property review
The online estimate provides realistic orientation. For the final quote, we capture roof areas, access and technical conditions through drone surveying and property review: precise, not based on satellite assumptions.
Electrical
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.
Quote
Materials, installation, scaffolding, electrical work, registration and commissioning are listed individually so variants and ranges remain traceable.
Execution standard
Regional clarification
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.

The Founders
Two founders, two domains of expertise and one shared conviction: solar installations work long-term only when engineering and business case fit together from the start. Before signing, you know who calculates your project and who builds it.

Marc handles the technical side: planning, structural analysis, system integration and execution that remains traceable a decade later. An engineering mindset means no improvisation, only well-reasoned solutions for every roof.
Building in focus
Full-black, in-roof or flat-roof: in Baltschieder we plan not for a datasheet, but for a building that has to stand up architecturally and within its local context.

Architecture first
In Baltschieder, materiality, visual lines and technical details are aligned so the system fits the design language and performs cleanly over time.
Mounting, waterproofing, shading and the electrical setup are clarified before anything is promised. No quote without understanding the building.
The system grows precisely into the building: tight penetrations, protected facade, modules sliding into the rails, and an aesthetic that fits the architecture instead of disturbing it.
The inverter, registration and documentation are done, cable routes and labels stay traceable, and the roof becomes a calm, reliable energy source for everyday use.

Clarity before commitment
The key points are explained clearly, factually and without artificial urgency. For details, we assess your property in its project context.
It depends on canton/municipality, property and protection regulations. In many cases, a notification procedure is sufficient; in core zones, for heritage protection, or for structural changes, further clarifications are needed. We clarify this early and provide the required documents.
Municipality check
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.
Baltschieder belongs to Canton Wallis. We therefore combine the local roof assessment with cantonal requirements for subsidies, permits, grid connection and documentation.
Canton Wallis guideline: approx. 1400 kWh/m² global irradiation per year.
Relevant grid operators in the canton: EnBAG, EW Obergoms. Metering concept and registration are clarified before execution.
Solar obligation: new buildings >300m² floor area must have 40% solar equipment (since 1.1.2023). Gondosolar and large alpine systems: Solarexpress procedure. Vineyard agri-PV: flexible regulations. Normal notification procedure for standard systems.
Solar obligation for new buildings: since 1.1.2023, buildings >300m² floor area must equip 40% of building area with solar. EW Obergoms: up to 25.63 Rp./kWh — highest feed-in tariff in Switzerland! Mainly thermal subsidies at cantonal level.
In the region
Before a project begins, you need clarity on roof, consumption and technical setup. The following steps are arranged so you move from a first overview to a reliable foundation, without any pressure.
Roof, usage profile and target setup are aligned before a polished but vague number enters the room.
Electrical scope, metering, grid-operator constraints and expansion path are read as one connected system.
If the project fits, the next step is a traceable quote instead of pressure or sales haze.
Next step
The initial assessment remains the cleanest entry point: fast enough for momentum, concrete enough for a real conversation based on your building.
