Solar panels: Martigny, Valais Plan your project 2026

Your solar project: Martigny. Prepare a timetable showing procedures, approvals and work in their actual sequence. Confirm the supporting structure, anchor points and mounting design. Reserve space and access for inspections and future replacements. Specify fall protection and access for installation and maintenance.

Net cost — model

CHF 16'960

Payback — model

10-13 years

The 8 kWp scenario above uses the cantonal model assumptions: indicative output, 40 % self-consumption, hypothetical purchase and export tariffs, installed costs of CHF 2 200 to 2 800/kWp and assumed Pronovo support of CHF 360 to 400/kWp. It is not a local quote. Recalculate using your roof, hourly demand, contracts and confirmed grants; include fees, losses and replacements.

Your roof: Martigny

Adapt the project to the building’s use, whether a house, apartment building or business premises. Include future vehicle charging or heating changes in the consumption scenario.

In all cases, the useful surface area is almost always less than the gross surface area announced. Skylights, chimneys, setbacks, shading and future maintenance needs must be integrated before talking about final power.

Request the weather assumptions, losses and monthly results behind the stated output. Agree on tests, inspections and documents to be provided at handover.

Exposure and access: Martigny

Request a survey of nearby shading and the horizon, with monthly generation estimates. Compare options for your building using the same weather data and loss assumptions.

Use the building’s hourly consumption to size the project. Compare mounting and removal arrangements against the condition of the roof covering.

Full cost and grants: Martigny

The displayed scenario uses an indicative installed cost for 8 kWp. A quote must specify equipment, roofing and electrical work, connection, inspections and fees before deducting confirmed grants.

Programmes depend on the municipality and available funds. Obtain written confirmation of amounts, timing, limits and combined support for your address before including them in the budget.

Prepare a timetable showing procedures, approvals and work in their actual sequence. Record amounts, deadlines and revision terms in the offer.

Output must be assessed for the actual roof, its orientation, shading and condition. Tariffs depend on the grid, product and contract; a cantonal average does not replace your bill.

Building procedures: Martigny

Assess shifting compatible loads to solar hours before adding storage. Keep the simulation assumptions so results can be compared after commissioning.

A serious estimate specifies who prepares the announcement, who manages the connection, who follows the administrative back and forth and how any comments are absorbed into the planning.

In Valais, residential photovoltaics first go through Pronovo; Any municipal aid or other energy measures must be confirmed before signature.

Request plans, equipment references and service boundaries before accepting a price. Identify the service contact and stated response times after commissioning.

Compare installers: Martigny

When comparing installers, check access to the installation site. Then check the after-sales response times. These details matter more than the advertised price alone.

The quality gaps are quickly seen in the annexes: level of technical inspection, self-consumption assumptions, electrical diagram, service after commissioning and clarity of service limits.

Before choosing an installer, ask who attends the site after a fault, the travel charges and stated response time. A registered office address does not establish service availability for your building.

Check building protection and appearance requirements with the relevant authority. Record who installs, inspects and supports each part of the system in the contract.

Frequently asked questions: Martigny

Prepare these questions about the roof, costs, storage and procedures before comparing offers.

What should I check during the roof survey?

Show chimneys, roof windows and other obstacles on the installation layout. Confirm voltages, currents and module compatibility with the selected inverter.

How should I compare self-consumption and exports?

Compare avoided purchase costs and surplus export prices with your hourly demand. Self-consumption reduces purchases when generation is used on site; the choice also depends on full cost and losses.

How should I assess adding a battery?

First compare an option without storage for the same demand. Measure usable roof area with obstacles and required clearances included. Price the necessary electrical distribution board changes and protection devices.

Which procedures should I confirm for this building?

The procedure depends on the plot, building and integration. Present the plan to the municipality to confirm notification or permit requirements and any protection constraints before ordering.

What should I request from installers?

When comparing installers, check an on-site technical survey before relying on sales claims. Then check long-term access and maintenance arrangements. These details matter more than the advertised price alone.
