Your solar project: Courroux. Request a technical site survey before relying on a sales estimate. Include the constraints identified during the survey in the quotation. Define included and excluded work during the technical survey. Distinguish avoided purchase costs from the tariff paid for exported surplus.

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: Courroux

For a detached house, check roof condition, shading and electrical capacity before signing. A single owner’s decision still requires a technical roof survey.

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.

Measure usable roof area with obstacles and required clearances included. Keep the simulation assumptions so results can be compared after commissioning.

Exposure and access: Courroux

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.

Check the simultaneous consumption used to estimate avoided electricity purchases. Identify the service contact and stated response times after commissioning.

Full cost and grants: Courroux

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.

Request a technical site survey before relying on a sales estimate. Record who installs, inspects and supports each part of the system in the contract.

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: Courroux

Check building protection and appearance requirements with the relevant authority. Confirm voltages, currents and module compatibility with the selected inverter.

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 the canton of Jura, residential photovoltaics refers to the federal Pronovo mechanism; any municipal aid must be confirmed before signature.

Reserve space and access for inspections and future replacements. Request a schedule that accounts for weather, access and team availability.

Compare installers: Courroux

When comparing installers, check a detailed comparison of each quotation item. Then check the written allocation of responsibilities. 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.

Request the weather assumptions, losses and monthly results behind the stated output. Price the necessary electrical distribution board changes and protection devices.

Frequently asked questions: Courroux

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

What should I check during the roof survey?

Specify the work assigned to subcontractors and who is responsible for each task. Confirm the supporting structure, anchor points and mounting design.

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. Assess shifting compatible loads to solar hours before adding storage. Include the constraints identified during the survey in the quotation.

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 the obstacles that reduce usable roof area. Then review the tests and documents planned for handover. These details matter more than the advertised price alone.
