Your roof: Belfaux
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.
Define included and excluded work during the technical survey. Check how equipment can be accessed and components replaced without damaging the roof covering.
Exposure and access: Belfaux
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.
Measure usable roof area with obstacles and required clearances included. Specify fall protection and access for installation and maintenance.
Full cost and grants: Belfaux
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.
Check the simultaneous consumption used to estimate avoided electricity purchases. Agree on tests, inspections and documents to be provided at handover.
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: Belfaux
Request plans, equipment references and service boundaries before accepting a price. Specify fall protection and access for installation and maintenance.
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 Fribourg, photovoltaics go through Pronovo; cantonal aid mainly concerns solar thermal, renovation or the Buildings Program. Verify any local support before including it in the budget.
Request a technical site survey before relying on a sales estimate. Compare mounting and removal arrangements against the condition of the roof covering.
