Your roof: Crissier
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.
Reserve space and access for inspections and future replacements. Check how equipment can be accessed and components replaced without damaging the roof covering.
Exposure and access: Crissier
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.
Request the weather assumptions, losses and monthly results behind the stated output. Specify fall protection and access for installation and maintenance.
Full cost and grants: Crissier
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.
Use the building’s hourly consumption to size the project. 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: Crissier
Simulate generation and available surplus before choosing a battery. Agree on tests, inspections and documents to be provided at handover.
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 Vaud, distinguish between Pronovo, municipal aid and Buildings Program if solar accompanies a renovation. If this timeline is poorly managed, you lose time and sometimes value on aids.
Prepare a timetable showing procedures, approvals and work in their actual sequence. Compare mounting and removal arrangements against the condition of the roof covering.
