Your roof: Peseux
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.
Check building protection and appearance requirements with the relevant authority. Request a schedule that accounts for weather, access and team availability.
Exposure and access: Peseux
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.
Compare quotation items for the same scope of work and supply. Confirm the supporting structure, anchor points and mounting design.
Full cost and grants: Peseux
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.
Specify the work assigned to subcontractors and who is responsible for each task. Include maintenance, insurance and foreseeable replacements in lifetime cost.
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: Peseux
Peseux joined the municipality of Neuchâtel on 1 January 2021. The City publishes former municipal regulations that remain applicable until replaced. Confirm the planning and building rules for your plot when preparing the solar layout.
Measure usable roof area with obstacles and required clearances included. Price the necessary electrical distribution board changes and protection devices.
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 Neuchâtel, distinguish between Pronovo, battery aid, large PV roofs and possible municipal aid. If the timeline is poorly managed, you lose time and sometimes value on helpers.
Simulate generation and available surplus before choosing a battery. Check how equipment can be accessed and components replaced without damaging the roof covering.
